  1) Hardware:

  1.1) Factory settings:The Gefran 600-R-R(D)-0-0-1 is factory set
  for PID heating, direct absolute alarm, input type «J» and access
  to the «EASY» programming menu

  (Protection level «0»).

  The main control output is mapped to «Out2» (terminals 19 &
  20). This is noteworthy as one would intuitively consider OUT1 to
  be the main output. Thisimplies that one changes the cycle time of
  the main control output by adjusting Ct.2 in the Out menu.The Alarm
  output is mapped to Out1 (terminals 21 & 22).

  1.2) Transmitter supply / Pt100: Inside the controller are
  jumper settings to connect either the third wire input for Pt100 or
  the internal +24V(10V)transmitter voltage to terminal no. 3Note:
  the factory setting of the jumper is for Pt100 input. You need to
  change the jumper setting to enable the +24V output on terminal no.
  3 (see sketch

  on hardware).The internal transmitter supply is common negative
  (internally linked to negative sensor input on terminal no. 2). The
  positive output is connected toterminal 3 via the jumper (see
  above).

  1.3) Transmitter supply voltage: inside the controller is a
  solder link to select the transmitter output voltage (24, 15, 10,
  5, 1.23VDC). Factory setting is

  24VDC (small track on PCB needs to be cut when changing to other
  voltage). (see sketch on hardware).

  1.4) Digital input: On models 600(I)-R-?-N-?-? the digital input
  is NOT isolated. It is common negative (terminal 6 and terminal 2).
  To activate the inputyou need to apply 24VDC to the digital input
  (terminals 5 and 6). Alternatively you can enable the internal 24V
  transmitter supply (jumper setting, seeabove) and use a dry contact
  between terminals no. 3 and no. 5

  1.5) Outputs: Type 600 controllers have up to 4 outputs,
  depending on the model. Each output can be mapped via software to
  perform one or more

  functions. It is for example possible to assign a combination of
  alarms to one output relay. It is also possible to assign the main
  control function to any ofthe outputs. If for example the relay
  contact on output 2 (factory setting for main control output) is
  damaged, you can by software change the main

  control function to output 1.Factory setting: output 1 is mapped
  to alarm 1 and output 2 is mapped to main control (heating).

  1.6) Analog output: Type 600-R-?-C-?-? and 600-R-?-W-?-? have a
  small PC-board attached to the CPU board. There is a jumper setting
  on this board: with the jumper in place (factory default) the
  output is set to 0(2)-10V. When the jumper is removed the output is
  0(4) to 20mA.

  5 PROGRAMMING and CONFIGURATION

  On the 600-R-?-C-?-? the analog output can only be used for
  control purposes.

  The 600-R-?-W-?-? can be configured for analog control or for
  analog retransmission.

  Change from 0-20 (0-10V) to 4-20mA (2-10V): This is a software
  setting. In the «Out» menu set rL.3=64 heat) or 65 (cool) for
  control purposes. Forretransmission go into the «U.CAL» menu,
  function 1. Connect a mA (V) meter to the analog output and adjust
  the value (4mA or 2V) with the UPand DOWN arrow keys. The factory
  default setting is 0—20 mA.

  2) Configuration menus:

  2.1) Description of menus:The programming of the 600 controller
  is divided into 10 menus:

  INF: the information menu contains general information (software
  version etc.)CFG: the configuration menu contains all parameters
  affecting the control behavior (enabling of self-/autotune, PID
  parameters, hysteresis, softstarttime, loop break power etc.)Ser:
  The serial communication menu only applies to controllers with
  serial communication. It allows selection of addresses, protocol,
  baud rate,Parity checking etc.InP: the input menu contains
  selection of input type, the input range, filters, and limits for
  setpoints.Out: the output menu allows selection of reference
  signals for the various alarms, alarm types, heater-and sensor
  failure functions, mapping ofcontrol output and alarms to the four
  output ports, setting of the cycle time for all PID outputs,
  assignment of the reference signal for the analogoutput.

  PAS: the following menus (7-9) are password protected. Entering
  a password of «99» allows access to these menus:

  Pro: the protection menu allows tamper proofing and restriction
  of access to the various menus and settings.Hrd: the hardware
  configuration menu allows enabling of control via serial comms,
  selection of control type (PID heat, heat-cool), the alarm
  types,function of the three LED’s (L1—L3) , the «Auto/Manual»
  key, the digital input, function of the lower displayLin: Custom
  linearization for the main input can be performed in 35 steps.

  U.CA: User calibration allows precision calibration of inputs
  and analog outputs.

  2.2) Getting into the various menus:Press and hold the «F» key
  on the controller down: The menus INF, CFG, Ser, InP, OuT, PASS and
  LEVEL 1(main menu displaying temperature andsetpoint) will appear
  in succession.Release the function key whenever the desired menu is
  displayed.Press the button briefly to get to the first parameter in
  the selected menu. The parameter type is indicated in the top
  display, the value is shown in thebottom display.Use the up/down
  arrow keys to change the parameter value.Press the function key
  briefly to accept the parameter value and to move on to the next
  parameter.Press and hold the «F» key down to move to other
  menus.

  Note: It is possible that some menus do not appear while holding
  the function key down. This is because the protection level is
  preventing access tothese menus. Refer to step 3.2)

  Password protected menus:Press and hold the «F» key on the
  controller down to get to «PAS». Release the F-key and enter the
  password: 99To get into the Pro menu, press the F-key briefly.To
  get into any subsequent menu (Hrd, Lin, U.CAL) press and hold the
  «F» key on the controller down to get to «PAS». Release the F-key
  and enterthe password: 99

  Now press and hold the function key down until the desired menu
  is displayed. Release the function key, then press the function key
  briefly to get tothe first parameter in the menu.

  3) Setting up the controller:When setting up a controller it is
  advisable to work through the menus in the following sequence:PAS
  (password=99)-Pro (enable access to menus), PAS (password=99)-Hrd,
  InP, Out and then CFG.The reason is that by selecting options in a
  menu, some parameters in another menu become superfluous and are
  thus skipped, making setting-upeasier.(e.g. in ON/OFF control the
  h.It and h.dt parameters are skipped)

  3.1) «Pro» protection (barring access to settings):The
  protection menu allows tamper proofing by restricting access to the
  various menus and settings. After configuring and tuning the
  controller werecommend setting Pro=12, thus protecting the setup,
  only allowing access to the control setpoint and the alarm
  setpoints.Pro=0 (factory default) allows access to the «Easy»
  Programming menu, which contains onlythe most commonly used set-up
  parameters.Pro=128 enables full access to all parameters.Pro=12
  allows access to the control setpoint and alarm setpoint, blocking
  access to all othermenus.Pro=13 will prevent changing of alarm
  setpoints.Pro=14 will also prevent changes to the control
  setpoint.

  3.2.3) Configuration parameters (CFG):

  Press and hold the «F» key down until you get to the CFG menu,
  then release the «F» key.Press the «F» key briefly. The top display
  will show:»h.Pb» Use the up/down arrow keys to select the
  proportional band for the main control

  output. The value is a % of the input range (Hi.S — Lo.S in the
  InP menu).E.g. for Type «J» sensors h.Pb =4 equals 40C (4% of
  1000C)

  Press the «F» key briefly. The top display will show:»h.It» Use
  the up/down arrow keys to select the integral time for the main
  control output. The

  time is set in minutes.Press the «F» key briefly. The top
  display will show:

  «h.dt» Use the up/down arrow keys to select the derivative time
  for the main control output.The time is set in minutes. (this
  parameter should not exceed of the h.It parameter)See note 4.10
  (PID parameters)

  Press the «F» key briefly. The top display will show:»hP.H»
  Normally this parameter remains set to 100 %. Use the down arrow
  key if you want toreduce the maximum output power of the control
  output. This parameter is useful if

  elements are rated too high for the application.Press the «F»
  key briefly. The top display will show:»hy.1″ This sets the
  hysteresis for the Alarm output (output 1) and is a % of the input
  range. Itshould normally remain set at 0.1 Use the up/down arrow
  keys to change thisparameter. Setting it to 100 means the alarm
  will latch.

  Alternatively hy.1 sets the time delay before the alarm trips if
  the alarm type (Al.t parameter) in the Out menu is set to n+32 or
  n+64.

  The value is a % of the inputrange (Hi.S — Lo.S,) in the InP
  menu.e.g. for Type «J» sensors h.Pb =4 equals 40C (4% of 1000C)

  «h.It» Sets the integral time for the main control output. The
  time is set in minutes.

  «h.dt» Sets the derivative time for the main control output. The

  At 50% the proportional band is centered about the set point.At
  100% the proportional band is entirely above the set point.

  This function only applies to PID control.See note 19

  «A.rS» Anti reset reduces the window (scale points 0-9999)

  Standard Sensor

  8 DECIMAL POINT

  9 INPUTS (SCALE, TYPE)

  When changing the decimal point the parameters Lo.S, Hi.S, oFS,
  Lo.L and Hi.L are affected and also the control and alarm
  setpoints! Make

  sure to check and adjust all these parameters after changing the
  decimal point.For example changing the decimal point from 0 to 1
  will change Hi.S from 1000 to 100.0. As a result the unit will
  register a sensor fault if the

  temperature exceeds 100C. Set the HI.S parameter to 999.9 to
  rectify this.

  10 CONTROL MODE

  The control type is determined by the Ctr parameter in the Hrd
  menu.

  Most commonly used setups are:

  Ctr=6 PID heating (factory default setting)Ctr=9 ON / OFF
  heating (the h.Pb parameter in the CFG menu sets the hysteresis,
  normal setting: h.Pb=0.1)

  Ctr=10 ON / OFF cooling (the c.Pb parameter in the CFG menu sets
  the hysteresis, normal

  setting: c.Pb=-0.1)

  Ctr=12 PID heating, ON/OFF cooling (c.Pb sets hysteresis, same
  as above): This controlmode is ideally suited for extruders with
  air cooling using fans. In this mode the

  controller prevents overlap of the heating and cooling
  output.

  The deadband (temperature band between heating and cooling) is
  set by adjusting c.SP in the CFG menu. Because overlapping of
  heating

  and cooling is prevented by the controller, it is possible to
  set the deadband very small ( e.g. c.SP=0.2), thus achieving very
  accurate control.

  This control mode is preferable to normal PID heating (Ctr=6)
  using the alarm function for cooling. Normal PID heating with Alarm
  usuallynecessitates a large deadband (5-10C) to prevent overlapping
  of the heat / cool operations.

  Please note: you have to enable the cooling output (Out1) by
  setting rL.1=1 in the Out menu.

  Also check that the heating output is enabled by rL.2=0
  (alternatively rL.3=0 for analog control).

  You also have to set the deadband c.SP in the CFG menu.

  Ctr=12 PID heating, PID cooling: This control mode is ideally
  suited for applications where the

  cooling medium (air, water, oil) is controlled via a solenoid
  valve or motorized valve.

  The deadband (temperature band between heating and cooling) is
  set by adjustingc.SP (e.g. c.SP=0.2) in the CFG menu.

  The PID parameters for the cooling function are automatically
  set by entering the

  relevant cooling medium in C.ME in the CFG menu (e.g. C.ME=2 for
  water cooling).

  Check the note above regarding enabling of the cooling
  output.

  The input scale is defined by the parameters Lo.S and Hi.s in
  the CFG menu.

  If the temperature falls outside the scale defined by Lo.S and
  Hi.s, the controller will indicate a sensor fault.

  Changing the input scale also affects the proportional band in
  PID control because h.Pb and c.Pb are a % of the input range.

  The Gefran 600 controller allows changing of the sensor
  scale.

  For standard temperature sensors (thermocouples, Pt100) the Lo.S
  and Hi.s parameters should normally correspond with the minimum
  and

  maximum temperature scale of the particular sensor, as listed in
  the input table.Example: for a type «J» thermocouple Lo.S=0 and
  Hi.s=1000 .

  NB: When a decimal point is selected, these parameters are
  affected and must be reset. For instance on a sensor input type «K»
  setting

  dP.S=1 in the InP menu will change Lo.S=0 to 0.0 and Hi.s= 1300
  (no decimal point) to130.0 (with decimal point) . When the
  temperature

  rises above 130.0C, the controller will thus indicate a sensor
  fault. The Hi.S parameter must therefor be reset to Hi.s=999.9 to
  eliminate this

  problem.

  Analog Inputs

  For analog inputs (e.g. 4-20mA or 0-10V) Lo.S and Hi.s represent
  the zero and span of the input signal.Example: input type is a
  temperature transmitter 4-20mA and a zero and span of -5-C and
  +100C respectively (4mA representing -50C

  and 20mA representing +100C).

  The correct setting for Lo.S= -50 and Hi.S= +100. If a decimal
  point is set (dP.S=1) then the correct setting is Lo.S= -50.0 and
  Hi.S= +100.0

  Custom Inputs (user calibration)

  For custom lnputs the calibration (32 step) is performed in the
  LIN menu. The steps are numbered from 5.00 to 5.32Example: Custom
  input tyP.=53 (1-5V), corresponding to a reading of 0 to 150C

  Procedure:

  divide the input signal range by 32: (5-1)/32=4/32=0.125 Venter
  the corresponding value to be displayed for each step. Since the
  curve is not linear, look up the matching reading for each input
  value

  on the graph or table for the input device.step 5.00 (first
  step): enter value for input signal 1V ( in this case «0»)

  step 5.01 (second step): enter value for input signal 1.125V

  step 5.02 (third step): enter value for input signal 1.250V

  continue through all 32 steps, increasing the input signal by
  0.125V per step and entering the corresponding value to be
  displayed.step 5.32 (final step): enter value for input signal 5.0V
  (in this case «150»)

  Now set the input range in the InP menue as follows: Lo.S=0 and
  Hi.S=150. This will define when the input signal is out of
  range.

  For very fast processes (e.g. air heaters and Infrared heaters)
  PID control performance is improved by:

  -selecting a faster derivative action sampling time. This is
  achieved by adding 64 to the Ctr parameter in the Hrd menu ( e.g.
  Ctr=6+64=70).-reducing the digital input filter action by reducing
  FLT (e.g. FLt=0.1) in the InP menu.

  -selecting the shortest possible cycle time for the control
  output (e.g. Ct.2=1 in the Out menu)

  -using analog output (20mA, 10V) in conjunction with Thyristor
  drives.

  Heating/Cooling control with relative gain

  In this control mode (enabled with Ctr = 14 parameter) the type
  of cooling has to be specified.

  Cooling PID parameters are therefore calculated based on heating
  parameters according to the specified ratio.

  (for example: C.ME = 1 (oil), H_Pb = 10, H_dt = 1, H_It = 4
  implies: C_Pb = 12,5, C_dt = 1, C_It = 4)

  We advise you to apply the following values when setting output
  cycle times:Air T Cool Cycle = 10 sec.

  Oil T Cool Cycle = 4 sec.

  Water T Cool Cycle = 2 sec.

  NB.: Cooling parameters cannot be modified in this mode.

  Control mode:The control type is determined by the Ctr parameter
  in the Hrd menu.Most commonly used setups are:

  Ctr=6 PID heating (factory default setting)Ctr=9 ON / OFF
  heating (the h.Pb parameter in the CFG menu sets the hysteresis,
  normal setting: h.Pb=0.1)

  Ctr=10 ON / OFF cooling (the c.Pb parameter in the CFG menu sets
  the hysteresis, normalsetting: c.Pb=-0.1)

  Ctr=12 PID heating, ON/OFF cooling (c.Pb sets hysteresis, same
  as above): This controlmode is ideally suited for extruders with
  air cooling using fans. In this mode thecontroller prevents overlap
  of the heating and cooling output.The deadband (temperature band
  between heating and cooling) is set by adjusting c.SP in the CFG
  menu. Because overlapping of heating and coolingis prevented by the
  controller, it is possible to set the deadband very small ( e.g.
  c.SP=0.2), thus achieving very accurate control.

  This control mode is preferable to normal PID heating (Ctr=6)
  using the alarm function for cooling. Normal PID heating with Alarm
  usually necessitatesa large deadband (5-10C) to prevent overlapping
  of the heat / cool operations.Please note: you have to enable the
  cooling output (Out1) by setting rL.1=1 in the Out menu.Also check
  that the heating output is enabled by rL.2=0 (alternatively rL.3=0
  for analog control).

  You also have to set the deadband c.SP in the CFG menu.

  13 ALARMS

  Alarm Reference Signals

  Enabling Alarms:Before any alarms can be configured they need to
  be enabled (see Al.n in the Hrd menu).

  If you do not require an alarm function, set AL.n=0. This will
  remove the prompt for an alarm setpoint in the level1 menu.For
  combined heat/cool control two outputs will be occupied. Hence you
  need a controller with more than two outputs (e.g. 600-R-D-R-0-1)
  if you wantheat/cool control with alarm.

  If you use a controller with only two outputs for heat/cool
  control (e.g 600-R-R-0-0-1), no spare output for alarm is
  available, hence the alarm should bedisabled by setting Al.n=0

  It is possible to enable up to 3 alarms. In addition the HB
  alarm (heater break) and the LBA (sensor fault) alarm can be
  activated.Alarm outputs:Each alarm can be assigned to any one of
  the available outputs (see parameters rL.1-rL.4 in the Out menu).It
  is possible to assign more than one alarm to the same output. It is
  therefor possible to use one output relay to operate if either one
  ( AL1 or AL2)

  alarm condition occurs. Alternatively the condition can be set
  that both alarms have to be flagged ( AL1 and AL2) before the
  output relay operates.Alternatively the same alarm can be assigned
  to more than one output. For example setting rL.1=2 and rL.3=11
  will cause Relay Out1 to operate ifalarm 1 is on and relay Out3 to
  operate if both alarm1 and alarm2 are on.This makes alarm functions
  very versatile and reduces the number of output relays
  necessary.Example: Extruder with heat / cool control, a contactor
  to shut down the machine if a high temperature condition or low
  temperature condition occurs,

  and a relay to start the process when the temperature is at
  operating temperature.This would normally necessitate 5 outputs
  (heat, cool, high alarm, low alarm, symmetrical alarm). On the
  Gefran 600 this can be achieved with 4outputs, using the
  600-R-D-R-R-1.

  The alarm reference signals (usually the process variable) are
  set by the Al.r-A3. parameters in the Out menu.

  There are two variables that can cause alarms to trigger:Firstly
  you can cause an alarm in response to a change in the process
  variable PV ( e.g high temperature condition, low temperature
  condition etc.)You can also cause an alarm if the control setpoint
  is set to excessive levels.The reference setpoint for an alarm can
  either be absolute or relative to the main setpoint (see next
  section)

  Al.r=0 ( normal setting) means the alarm will react if the main
  input signal is higher (lower) than the AL.1 setpointAl.r=1 means
  the alarm will react if the main (active) setpoint is set higher
  (lower) than the AL.1 setpoint. (only applies to absolute alarm).
  This featureis useful to draw attention if the main setpoint is set
  to excessive levels by machine operators.Al.r=2 is identical to
  Al.r=0 except that it only applies to relative alarms, referred to
  the active setpoint in multiset function (special case where a
  second

  control setpoint is introduced via serial communication)The
  above also applies to A2.r and A3.r

  The alarm types are set by the A1.t-A3.t parameters in the Out
  menu.Alarms can be set to be absolute, relative or symmetrical.

  «Direct» alarm means the alarm contact closes when the input
  variable (eg. Temperature) exceeds the alarm setpoint»Inverse»
  alarm means the alarm contact closes when the input variable drops
  below the alarm setpoint.»Absolute» means the setpoint is
  independent of the active (control) setpoint.»Relative» means the
  alarm setpoint is relative to the active (control) setpoint

  «symmetrical» means the alarm is active inside / outside a
  window around the control setpoint. It is used to detect abnormal
  deviation (positive andnegative) of the input variable from
  setpoint.Alarms can be delayed by adding 32 (delay in seconds)or 64
  (delay in minutes) to the selected alarm parameter. The
  Hy-parameter (Hy.1 -Hy.4 in

  CFG menu) becomes the delay time.Examples:Al.t=0 means that the
  alarm relay will close when the temperature exceeds the alarm
  setpoint («high temperature alarm»)Al.t=2 and an alarm setpoint
  AL.1=10 means that the alarm relay will energise when the
  temperature rises by 10C above the control setpoint.

  Al.t=33 (1+32) and Hy.1=45 means that a low temperature alarm
  will come on if the low temperature condition has prevailed for 45
  seconds

  Alarm Types

  The system will indicate a sensor fault whenever the input
  signal falls outside the range set by Lo.S and Hi.s ( InP menu).In
  this condition the main control output power will default to the %
  set in FA.P (CFG menu).

  This is a useful feature, allowing you to finish a production
  run before attending to a sensor fault. We recommend monitoring the
  % outputpower during normal operation (temporarily set dSP=2 in HrD
  menu) and then entering this value as the FA.P parameter.

  Alternatively set FA.P=0 to disable the control output (failsafe
  mode).

  Sensor Fault

  14 SENSOR FAULT AND LOOP BREAK (LBA) ALARM

  LBA loop break alarm:

  The LBA alarm is enabled by setting Al.n= (between 16 and 31) in
  Hrd menu, but can be disabled by setting Lb.t=0 in the CFG
  menu.

  Lb.t sets the waiting time for a LBA alarm. The % output power
  under fault condition is set by Lb.P in the CFG menu. An alarm
  output can beenabled by setting rL.1 (2, 3 or4)=6 in the Out menu.
  LBA is triggered when the output power is fully on (100%) but the
  process variable does

  not respond. This will typically happen when the heating circuit
  is defective, a fuse is blown, the thermocouple cable is short
  circuited or the

  sensor is not mounted in position.

  Apart from triggering an alarm output, the LBA alarm can be
  configured to force the control output into a preset % output power
  when a loop

  fault occurs. The idea is to enter an output power at which the
  process will continue at normal temperature without causing
  overheating.NB: Do not set the Lb.t too short to avoid nuisance
  tripping. Do not set Lb.t too long causing overheating before
  output power is reduced.

  15 HEAT BREAK ALARM (AUX. INPUT 2)

  controllers with input/output 3 option =»H» monitor the load
  current via a 50mA secondary current transformer (refer to Gefran
  CT type 330200

  and 330201). The load current can be displayed via the bottom SV
  display (set dSP=1 in Hrd menu). The scaling of the input is
  achieved bysetting LS.2 (normally LS2=0) and HS.2 in the InP
  menu.

  The heater Break (HB) Alarm is enabled by setting either rL.1 or
  rL.2 or rL.3 or rL.4=5, 13, 14, 15 or 16 and by setting Hb.F to the
  appropriate

  level (see Out menu).

  A.Hb in level 1 menu sets the HB alarm setpoint.Hb.t in the CFG
  menu sets the waiting period before a HB alarm is triggered.

  16 MANUAL MODEThe controller can be set into manual mode. This
  is achieved by setting but.=1 in the Hrd menu. It is also
  recommended to set either Ld.1,

  LD.2 or Ld.3=17 (flashing) in the the Hrd menu, thus getting LED
  indication if the controller is in manual mode. By operating
  theAUTO/MANUAL button on the faceplate the controller will switch
  from normal control to manual control. The PV display ( bottom
  display) will

  now show the % output power. The power can be adjusted via the
  UP/DOWN arrow keys.

  The controller will return to AUTO mode if the AUTO/MANUAL
  button is operated again.

  HB ALARM FUNCTION

  This type of alarm depends on use of the current transformer
  (C.T.) input.

  It can signal variations in load input by identifying the
  current value in ammeter input in the range (0 … HS.2). It is
  enabled by means ofconfiguration code (AL.n); in this case, the
  alarm trip value is expressed in HB scale points.

  By means of code Hb.F (Out phase), select the type of
  functioning and the assigned control output.

  The alarm limit setting is A.Hb.

  The direct HB alarm trips when the ammeter input value is below
  the limit set for Hb.t seconds of the «ON» time for the selected
  output.The HB alarm can be activated only with ON times greater
  than 0.4 seconds (excludes continuous output).

  The HB alarm also checks load current during the OFF interval of
  the cycle time for the selected output. The HB alarm trips if the
  measured

  current exceeds approximately 12.5% of the full scale set for
  HB.t seconds of OFF status of the output (parameter HS.2 in
  InP).

  The alarm is reset automatically if its cause is
  eliminated.Setting limit A.Hb = 0 disables both types of HB alarms,
  with de-energizing of the assigned relay.

  You can display the load current by selecting the item In.2.
  (level 1).

  NOTE: ON/OFF times refer to the cycle time set for the selected
  output.

  Continuous alarm Hb_F = 3 (7) is active for a load current value
  below the set limit. It is disabled if the heating (cooling) output
  value is below3%.

  HOLD function

  The input value and alarms are frozen while the logic input is
  closed.With logic input closed, a reset turns OFF both the relay
  outputs and the alarms latch.

  If a process is out of tune we recommend to first disable the
  Integral and Derivative action by setting the Integral and
  Derivative parameters to

  zero. Increase the proportional band until you obtain stability
  (no cyclic fluctuation). You will get a constant error (offset).
  Now introduce integral

  action. This will remove the error (offset). If excessive
  ringing occurs, increase the integral time. Reduce the integral
  time if the error reducestoo slow. Now add a very short Derivative
  time (e.g. h.dt=0.02), not more than 25% of the Integral time.

  A) Enter the setpoint at its working value.

  B) Set the proportional band at 0.1% (with on-off type
  setting).C) Switch to automatic and observe the behavior of the
  variable. It will be similar to that in the figure:

  D) The PID parameters are calculated s follows: Proportional
  band

  Peak

  P.B.= —————————————- x 100

  (V max — V min)

  (V max — V min) is the scale range.

  Integral time: It = 1.5 x T

  Derivative time: dt = It/4

  E) Switch the unit to manual, set the calculated parameters.
  Return to PID action by settingthe appropriate relay output cycle
  time, and switch back to Automatic.

  F) If possible, to optimize parameters, change the setpoint and
  check temporary response. Ifan oscillation persists, increase the
  proportional band. If the response is too slow, reduce it.

  The function of this display can be configured by setting the
  dSP parameter in the Hrd menu.

  Normally dSP=0, showing the control setpoint. However the
  display can also be configured to display the value of the
  auxiliary input, the

  output power or the deviation of the process variable from the
  setpoint.Display of the % output power (dSP=2) is useful to
  determine the output power during normal running conditions, thus
  obtaining the value to

  feed into the FA.P parameter in the CFG menu. This will then be
  the % output power the controller defaults to when a LBA (sensor
  fault)

  alarm occurs.

  PID parameters must be tuned to provide accurate control . There
  is often a tradeoff between rapid response to deviations from the
  setpoint ,

  elimination of overshoot and stability of the process. PID
  parameters can either be tuned manually or automatically through
  selftuning or

  autotuning.

  PID parameters:

  The PID parameters determine the control performance and are
  settable in the CFG menu.

  P: Proportional band:

  The function of the Proportional band (see h.Pb and c.Pb) is to
  eliminate the cyclic overshoot/undershoot caused by thermal lag.
  This isachieved by reducing output power before the setpoint is
  reached, thus anticipating the overshoot. The closer one gets to
  the setpoint, the less

  power is provided. The proportional band is expressed as a
  percentage of the input scale (Hi.S-Lo.S). See example below.

  A very narrow proportional band can lead to cyclic
  overshoot/undershoot. An excessively wide proportional band will
  slow down the heat up

  time becvause power is reduced too early.Proportional control
  results in an error (offset).

  e.g. for a type «J» input with Lo.S=0 and Hi.S=1000 and h.Pb=4.5
  the proportional band is 4.5% of (1000-0)=45C. As a result the
  output

  power of the control output will be reduced when the rising
  temperature enters a 45C window below the setpoint.

  I: Integral parameter

  The Integral parameter (see h.it and c.it) automatically removes
  the error (offset) caused by the proportional control. It reduces
  or increases

  power to counteract any deviation of the process variable from
  setpoint. The integral parameter represents time («Integral time»)
  and isexpressed in minutes. A long integral time results in slow
  correction of errors. A very fast integral time can cause ringing
  (oscillation) as a

  result of aggressive error correction.

  D: Derivative parameter

  The Derivative parameter (see h.dt and c.dt) counteracts rapid
  changes in the process variable. It is useful to reduce overshoot
  caused by

  aggressive Integral action. It also provides fast corrective
  action to a sudden change in the process variable. The Derivative
  parameter

  represents time («Derivative time») and is expressed in minutes.
  A long Derivative time results in a strong response to a change in
  the processvariable. Derivative time should be used with caution as
  it can lead to instability by overreacting to noise
  (electromagnetic interference) on the

  sensor input line. As a rule of thumb the Derivative time should
  be less than 25% of the Integral time. Any higher value will lead
  to a conflict

  between Integral and Derivative action, resulting in the process
  spiraling out of control.

  18 PID PARAMETERS, AUTOTUNE, SELFTUNE

  Manual Tuning

  L1, L2,L3 LED Displays

  The three LEDs on the left hand side of the faceplate can be
  configured to indicate various conditions. The function of each LED
  is

  determined by the Ld.1-Ld.3 parameters in the Hrd

  menu. The LEDs can also be configured to flash by adding 16 to
  the selected parameter.

  Each LED can be assigned a different function. It is also
  possible to assign the same function to all three LEDs . e.g.
  settingLd.1=Ld.2=Ld.3=24 will cause all three LEDs to flash when an
  error (sensor fault) occurs. This is a very visible indication.

  It is recommended to assign these LEDs when any of the following
  features are being enabled:

  Softstart, selftuning, autotuning, Manual/Auto mode.

  It makes diagnostics easy if one can see in which mode the
  controller presently is.

  Selftune is performed on a cold process (power-up) and is a
  once-off process. At power-up the controller will provide full
  power for a briefmoment, then monitor rise and fall of the process
  variable, calculate the PID parameters and the revert to normal
  control. It is useful to

  configure one of the three LEDs L1, L2 or L3 to indicate or
  flash while autotuning is active.

  How to activate self-tuning:1. Activation at power-up1.1 Adjust
  the setpoint to the required value

  1.2 Enable selftuning by setting Stun=2 in the CFG menu)1.3
  Switch off power to the instrument and to the process1.4 Make sure
  the process has cooled down and is far below the setpoint

  1.5 Apply power to the controller and the process

  2. Activation from keyboard2.1 Adjust the sepoint to the
  required value

  2.2 Enable self tuning by setting S.tu=2 in the CFG menu2.3
  Enable stop/start self tuning via the M/A button by setting but.=6
  in the Hrd menu2.4 Make sure the process has cooled down and is far
  below the setpoint Usually this is done by switching power off or
  disabling the heating

  elements2.5 Apply power to the process and press the M/A button
  on the faceplate of the instrument2. Activation from keyboard

  1) Continuous autotune:Enable autotuning by setting S.tu=1, 3 or
  5 in the CFG menu.

  The controller measures system oscillations to find the
  optimum.The calculated parameters are not stored.

  2) One-shot autotune:2.1) Enable autotuning by setting S.tu=8,
  10 or 12 in the CFG menu.2.2) Enable stop/start autotuning via the
  M/A button by setting but.=7 in the Hrd menu2.3) Initiate
  autotuning by pressing the M/A button on the faceplate of the
  instrument.The controller produces 10% variations from normal
  output power, examines the effect and optimizes PID parameters over
  time. It then stores

  the new PID parameters and automatically ends the autotuning
  process.

  The tuning process can be ended prematurely by pressing the M/A
  button.

  3) Automatic GO autotune:In this mode the controller
  automatically triggers an autotune cycle when the process deviates
  from the setpoint. There are four sensitivity

  levels (deviation thresholds) that can be selected by choosing
  the appropriate S.tu parameter.At power-up or after a change of
  setpoint, autotuning is inhibited for a time equal to five times
  the integral time, with a minimum of 5 minutes.3.1) Deviation
  threshold=0.5%: Set S.tu=24, 26 or 28 in the CFG Menu3.2) Deviation
  threshold=1%: Set S.tu=40, 42 or 44 in the CFG Menu3.3) Deviation
  threshold=2%: Set S.tu=72, 74 or 76 in the CFG Menu.3.4) Deviation
  threshold=4%: Set S.tu= 136, 138 or 140 in the CFG Menu.

  Selftune

  The reset facilities listed below effectively shift the
  proportional band in order to eliminate the error (offset) caused
  by proportional control. This

  method has its origin in the pre-microprocessor time when offset
  was removed by adjusting potentiometers.

  We recommend that you disable the parameters below buy setting
  them to 0.

  «rSt» This function shifts the proportional band manually, by a
  fixed amount (scale points -999 to 999), in order to remove a
  steady error. It can

  be used instead of the automatic Integral parameter.

  This function is only effective for a steady set point, as it
  calculates the shift according to the proportional band and not the
  set point for which

  it aims.

  «P,rS» Reset power is interchangeable with Manual Reset. It
  shifts the proportional band up and down about the set point by a
  percentage of

  the proportional band (0-100%).

  At 0% the proportional band is entirely below the set point.At
  50% the proportional band is centred about the set point.

  At 100% the proportional band is entirely above the set
  point.

  This function has no effect on on-off control.

  «A.rS» Anti reset reduces the window (scale points 0-9999)
  within the proportional band where the integral action is
  calculated. Normally

  integral action is active as soon as the process variable enters
  the proportional band Outside of this window the integral time is
  frozen. ie:

  Antireset will inhibit the integral action WITHIN the
  proportional band. Ultimately, this will decrease overshoot.

  «FFd» This function adds a calculated proportion of the set
  point to the output power, and thus effectively shifts the
  proportional band (0-100%). Like Manual Reset, it can be used
  instead of the integral parameter, but this function is more suited
  to processes that require large

  variations of the set point, due to its mechanism of calculating
  the shift according to the set point and not the proportional band
  itself.

  The formula for this calculation is as follows:

  OUT%(contribution of the feedforward power) = feedforward
  coefficient x (Set point — LoS) / (HiS — LoS)This OUT% is then
  added to the output power.
