  Summary of specific features included in SX series

  Soft Start algorithm. This takes the form of an output limit
  applied for a fixed duration after start up. Duration and threshold
  level may be set by the user. This is achieved by the internal
  timer as detailed in sections 5.4 and 13.

  When moving between setpoints (as forced by logic inputs, etc) a
  limited rate of change can be applied. Two parameters, one defining
  the rising rate of change (SP.RRT) and one defining falling rate of
  change (SP.FRT), are available in SX series. These parameters are
  found in the level 2 operator list section 5.3 and also in the
  Setpoint list section 10.1.

  Holdback is available in SX90 only to stop the ramp when the PV
  deviates from SP more than a set threshold value. The holdback
  parameter (HOLD.B) is found in the Setpoint list section 10.1.

  There are three local setpoints in SX80 and SX90 and the ability
  to take a remote setpoint in SX90 only. See also level 2 parameter
  section 5.3 and sections 9.1.11, and 10.

  A forced output may be activated when the controller is switched
  into Manual mode. The forced output is defined by parameters (F.MOD
  & F.OP) in the Control list section 11.10.

  In SX90 only and when the controller is configured for bounded
  valve position control a remote analogue input may be configured to
  read valve position. This is defined by a parameter (VPB.IN) in the
  Control list section 11.10.

  EIA422 digital communications is only available in SX90. See
  section 15.

  1. Installation and Basic Operation 1.1 What Instrument Do I
  Have? The SX series provide precise control of temperature or
  pressure in industrial processes and is available in two standard
  DIN sizes:-

  1/16 DIN Model Number SX80

  1/8 DIN Model Number SX90 A universal input accepts various
  thermocouples, RTDs or process inputs. Up to three (SX80) or six
  (SX90) outputs can be configured for control, alarm or
  re-transmission purposes. Digital communications is included in
  SX90 only. On start up the controller may be configured using a
  Quick Start code. It is possible, however, to add further features
  by configuring the controller in deeper levels of access. This is
  described in this manual.

  1.2 Unpacking Your Controller The controller is supplied
  with:-

  Sleeve (with the controller fitted in the sleeve)

  Two panel retaining clips and IP65 sealing gasket mounted on the
  sleeve

  B 96mm (3.78 inch) D 90mm (3.54 inch)

  1.4 Step 1: Installation This instrument is intended for
  permanent installation, for indoor use only, and enclosed in an
  electrical panel Select a location which is subject to minimum
  vibrations the ambient temperature is within 0 and 55oC (32 —
  131oF) and humidity 5 to 85% RH non condensing. The instrument can
  be mounted on a panel up to 15mm thick. To ensure IP65 and NEMA 4
  front protection, mount on a non-textured surface. Please read the
  safety information in section 3 before proceeding. The EMC Booklet
  is available for further installation information.

  1.4.1 Panel Mounting the Controller 1. Prepare a cut-out in the
  mounting panel to the size

  shown. If a number of controllers are to be mounted in the same
  panel observe the minimum spacing shown.

  2. Fit the IP65 sealing gasket behind the front bezel of the
  controller

  3. Insert the controller through the cut-out 4. Spring the panel
  retaining clips into place. Secure the

  controller in position by holding it level and pushing both
  retaining clips forward.

  5. Peel off the protective cover from the display.

  1.4.2 Panel Cut Out Sizes

  1.4.3 Recommended minimum spacing of controllers

  1.4.4 To Remove the Controller from its Sleeve

  The controller can be unplugged from its sleeve by easing the
  latching ears outwards and pulling it forward out of the sleeve.
  When plugging it back into its sleeve, ensure that the latching
  ears click back into place to maintain the IP65 sealing.

  2.3 Wire Sizes The screw terminals accept wire sizes from 0.5 to
  1.5 mm (16 to 22AWG). Hinged covers prevent hands or metal making
  accidental contact with live wires. The rear terminal screws should
  be tightened to 0.4Nm (3.5lb in).

  2.4 Precautions Do not run input wires together with power
  cables

  When shielded cable is used, it should be grounded at one point
  only

  Any external components (such as zener barriers, etc) connected
  between sensor and input terminals may cause errors in measurement
  due to excessive and/or un-balanced line resistance or possible
  leakage currents

  Not isolated from the logic outputs & digital inputs

  Pay attention to line resistance; a high line resistance may
  cause measurement errors

  2.18.1 General Note About Relays and Inductive Loads

  High voltage transients may occur when switching inductive loads
  such as some contactors or solenoid valves. Through the internal
  contacts, these transients may introduce disturbances which could
  affect the performance of the instrument. For this type of load it
  is recommended that a snubber is connected across the normally open
  contact of the relay switching the load. The snubber recommended
  consists of a series connected resistor/capacitor (typically
  15nF/100). A snubber will also prolong the life of the relay
  contacts. A snubber should also be connected across the output
  terminal of a triac output to prevent false triggering under line
  transient conditions.

  WARNING When the relay contact is open or it is connected to a
  high impedance load, the snubber passes a current (typically 0.6mA
  at 110Vac and 1.2mA at 230Vac). You must ensure that this current
  will not hold on low power electrical loads. If the load is of this
  type the snubber should not be connected.

  2.19 Controller Power Supply 1. Before connecting the instrument
  to the power line,

  make sure that the line voltage corresponds to the description
  on the identification label.

  2. Use copper conductors only.

  3. The power supply input is not fuse protected. This should be
  provided externally

  High voltage supply: 100 to 230Vac, +/-15%,

  48 to 62 Hz

  Recommended external fuse ratings are:-

  Fuse type: T rated 2A 250V.

  2.20 Digital Communications Digital communications uses the
  Modbus protocol. The interface is EIA422 (5-wire).

  Cable screen should be grounded at one point only to prevent
  earth loops.

  2.21.3 Cascade Control Temperature/Pressure The application of
  temperature control, with pressure limitation can be used when
  there is a pressure or temperature limit on anitem of equipment, or
  a temperature limit of a sensitive product. This application is
  described as Cascade Control. The application uses a single control
  valve to control both temperature and pressure. The example below

  2.21.4 Cascade Control Back Pressure/Pressure Reduction The
  objective here is to reduce the steam pressure but not to exceed
  the output of the boiler.

  The SX80 is set to the pressure necessary to maintain good
  boiler operating conditions. If the load exceeds the boiler
  capacity and the pressure at the boiler drops the control valve
  closes and maintains a suitable upstream pressure. When the steam
  demand falls,and allows the boiler pressure to return to its normal
  operating pressure, the valve will re-open.

  Consider the boiler pressure to be 10 bar g and the reduced
  pressure 5 bar g. The minimum allowable boiler pressure is 8 bar
  gwhich means that if this pressure is reached the valve is fully
  shut.

  The SX90 remote setpoint limit will represent the downstream
  setpoint, 5 bar g The SX80 local setpoint will represent the
  upstream setpoint, 8 bar g

  3. Safety and EMC Information This controller is intended for
  industrial temperature and process control applications when it
  will meet the requirements of the European Directives on Safety and
  EMC. Use in other applications, or failure to observe the
  installation instructions of this manual may impair safety or EMC.
  The installer must ensure the safety and EMC of any particular
  installation.

  Safety This controller complies with the European Low Voltage
  Directive 2006/95/EC, by the application of the safety standard EN
  61010.

  Electromagnetic compatibility This controller conforms with the
  essential protection requirements of the EMC Directive 2004/108/EC,
  by the application of a Technical Construction File. This
  instrument satisfies the general requirements of the industrial
  environment defined in EN 61326. For more information on product
  compliance refer to the Technical Construction File.

  GENERAL The information contained in this manual is subject to
  change without notice. While every effort has been made to ensure
  the accuracy of the information, your supplier shall not be held
  liable for errors contained herein.

  Unpacking and storage The packaging should contain an instrument
  mounted in its sleeve, two mounting brackets for panel installation
  and an Installation & Operating guide. Certain ranges are
  supplied with an input adapter. If on receipt, the packaging or the
  instrument are damaged, do not install the product but contact your
  supplier. If the instrument is to be stored before use, protect
  from humidity and dust in an ambient temperature range of -30oC to
  +75oC.

  SERVICE AND REPAIR This controller has no user serviceable
  parts. Contact your supplier for repair.

  Caution: Charged capacitorsBefore removing an instrument from
  its sleeve, disconnect the supply and wait at least two minutes to
  allow capacitors to discharge. It may be convenient to partially
  withdraw the instrument from the sleeve, then pause before
  completing the removal. In any case, avoid touching the exposed
  electronics of an instrument when withdrawing it from the sleeve.
  Failure to observe these precautions may cause damage to components
  of the instrument or some discomfort to the user.

  Electrostatic discharge precautions When the controller is
  removed from its sleeve, some of the exposed electronic components
  are vulnerable to damage by electrostatic discharge from someone
  handling the controller. To avoid this, before handling the
  unplugged controller discharge yourself to ground.

  Cleaning Do not use water or water based products to clean
  labels or they will become illegible. Isopropyl alcohol may be used
  to clean labels. A mild soap solution may be used to clean other
  exterior surfaces of the product.

  3.1 Installation Safety Requirements

  Safety Symbols Various symbols may be used on the controller.
  They have the following meaning:

  Helpful hints

  Personnel Installation must only be carried out by suitably
  qualified personnel in accordance with the instructions in this
  manual.

  Enclosure of Live Parts To prevent hands or metal tools touching
  parts that may be electrically live, the controller must be
  enclosed in an enclosure.

  Caution: Live sensors The controller is designed to operate if
  the temperature sensor is connected directly to an electrical
  heating element. However you must ensure that service personnel do
  not touch connections to these inputs while they are live. With a
  live sensor, all cables, connectors and switches for connecting the
  sensor must be mains rated for use in 230Vac +15%. .

  Wiring It is important to connect the controller in accordance
  with the wiring data given in this guide. Take particular care not
  to connect AC supplies to the low voltage sensor input or other low
  level inputs and outputs. Only use copper conductors for
  connections (except thermocouple inputs) and ensure that the wiring
  of installations comply with all local wiring regulations. For
  example in the UK use the latest version of the IEE wiring
  regulations, (BS7671). In the USA use NEC Class 1 wiring
  methods.

  Power Isolation The installation must include a power isolating
  switch or circuit breaker. This device should be in close proximity
  to the controller, within easy reach of the operator and marked as
  the disconnecting device for the instrument.

  Overcurrent protection The power supply to the system should be
  fused appropriately to protect the cabling to the units.

  Voltage rating The maximum continuous voltage applied between
  any of the following terminals must not exceed 230Vac +15%:

  relay output to logic, dc or sensor connections;

  any connection to ground. The controller must not be wired to a
  three phase supply with an unearthed star connection. Under fault
  conditions such a supply could rise above 264Vac with respect to
  ground and the product would not be safe.

  Equipment protected throughout by DOUBLE INSULATION

  ! Caution, (refer to accompanying documents)

  14 IM-P323-35: Part No 3231354 Issue 7.0 Feb-13

  Conductive pollution Electrically conductive pollution must be
  excluded from the cabinet in which the controller is mounted. For
  example, carbon dust is a form of electrically conductive
  pollution. To secure a suitable atmosphere in conditions of
  conductive pollution, fit an air filter to the air intake of the
  cabinet. Where condensation is likely, for example at low
  temperatures, include a thermostatically controlled heater in the
  cabinet. This product has been designed to conform to BSEN61010
  installation category II, pollution degree 2. These are defined as
  follows:-

  Installation Category II (CAT II)

  The rated impulse voltage for equipment on nominal 230V supply
  is 2500V.

  Pollution Degree 2

  Normally only non conductive pollution occurs. Occasionally,
  however, a temporary conductivity caused by condensation shall be
  expected.

  Grounding of the temperature sensor shield In some installations
  it is common practice to replace the temperature sensor while the
  controller is still powered up. Under these conditions, as
  additional protection against electric shock, we recommend that the
  shield of the temperature sensor is grounded. Do not rely on
  grounding through the framework of the machine.

  Over-temperature protection When designing any control system it
  is essential to consider what will happen if any part of the system
  should fail. In temperature control applications the primary danger
  is that the heating will remain constantly on. Apart from spoiling
  the product, this could damage any process machinery being
  controlled, or even cause a fire. Reasons why the heating might
  remain constantly on include:

  the temperature sensor becoming detached from the process

  thermocouple wiring becoming short circuit;

  the controller failing with its heating output constantly on

  an external valve or contactor sticking in the heating
  condition

  the controller setpoint set too high. Where damage or injury is
  possible, we recommend fitting a separate over-temperature
  protection unit, with an independent temperature sensor, which will
  isolate the heating circuit. Please note that the alarm relays
  within the controller will not give protection under all failure
  conditions.

  Installation requirements for EMC To ensure compliance with the
  European EMC directive certain installation precautions are
  necessary as follows:

  For general guidance an EMC Installation Guide is available —
  contact your supplier.

  When using relay outputs it may be necessary to fit a filter
  suitable for suppressing the emissions. The filter requirements
  will depend on the type of load.

  If the unit is used in table top equipment which is plugged into
  a standard power socket, then it is likely that compliance to the
  commercial and light industrial emissions standard is required. In
  this case to meet the conducted emissions requirement, a suitable
  mains filter should be installed.

  Routing of wires To minimise the pick-up of electrical noise,
  the low voltage DC connections and the sensor input wiring should
  be routed away from high-current power cables. Where it is
  impractical to do this, use shielded cables with the shield
  grounded at both ends. In general keep cable lengths to a
  minimum.

  4. Switch On A brief start up sequence consists of a self test
  during which the software version number and the Spirax instrument
  type is shown. The way in which the controller starts up depends on
  factors described below in sections 4.1, 4.2 and 4.3.

  previously been configured it will start up showing the Quick
  Configuration codes. This is a built in tool which enables you to
  configure the input type and range, control type and output
  functions alarm operation and language.

  ! Incorrect configuration can result in damage to the process
  and/or personal injury and must be carried out by a competent
  person authorised to do so. It is the responsibility of the person
  commissioning the controller to ensure the configuration is

  4.2 To Re-Enter Quick Code mode If you need to re-enter the
  Quick Configuration mode this can always be done as follows:- 1.
  Power down the controller

  2. Hold down the button, and power up the controller again.

  3. Keep the button pressed until code is displayed. 4. Enter the
  configuration code (this is defaulted to 4 in a

  new controller) 5. The quick start codes may then be set as
  described

  previously

  Parameters may also be configured using a deeper level of
  access. This is described in later chapters of this manual.

  If the controller is started with the button held down, as
  described above, and the quick start codes are shown with dots
  (e.g. K.D.0.1.E), this indicates that the controller has been
  re-configured in a deeper level of access and, therefore, the quick
  start codes may not be valid. If the

  quick start codes are accepted by scrolling to then the quick
  start codes are reinstated.

  4.3 Pre-Configured Controller or Subsequent Starts

  After the brief start up sequence the quick start codes are
  normally shown. It will then proceed to Operator Level 1.You will
  see the display similar to the one shown below. It is called the
  HOME display.

  4.4 Front Panel Layout ALM Alarm active (Red) OP1 lit when
  output 1 is ON (heating or VP raise) OP2 lit when output 2 is ON

  Operator Buttons:- From any display — press to return to HOME
  Press to select a new parameter. If held down it

  will continuously scroll through parameters.

  Press to decrease a value

  Press to increase a value

  4.4.1 To Set The Target Temperature. The controller can be run
  from either internal or remote setpoints. Depending on the
  configuration, the Working Setpoint will show:

  1. The Local Setpoint value (SP1, SP2 or SP3 depending on the
  setpoint selected)

  2. The Remote Setpoint value 3. A combination of both Local and
  Remote

  setpoints 4. Local setpoint with the Remote as a trim 5. Remote
  setpoint with the Local as a trim

  If mode 1 above is selected, then from the HOME display:-

  Press

  to raise the setpoint

  Press

  to lower the setpoint

  The new setpoint is entered when the button is released and is
  indicated by a brief flash of the display.

  When a Remote setpoint is configured (modes 2, 3, 4 or 5 above)
  the REM beacon is illuminated and the setpoint can only be adjusted
  by the voltage or current level on the Remote Input terminals or by
  adjusting the internal setpoints SP1, SP2 or SP3 shown in section
  10.

  4.4.2 Alarms Up to two process alarms may be configured using
  the Quick Start Codes section 4.1.1. Each alarm can be configured
  for:-

  Full Scale Low

  The alarm is shown if the process value falls below a set
  threshold

  Full Scale High

  The alarm is shown if the process value rises above a set
  threshold

  Deviation Low

  The alarm is shown if the process value deviates below the
  setpoint by a set threshold

  Deviation High

  The alarm is shown if the process value deviates above the
  setpoint by a set threshold

  Deviation Band

  The alarm is shown if the process value deviates above or below
  the setpoint by a set threshold

  If an alarm is not configured it is not shown in the list of
  operator level parameters, section 4.4.7 and 5.3.

  It is also possible to configure two further alarms, see section
  12, by selecting configuration level. Additional alarm messages may
  be shown such as CONTROL LOOP BROKEN. This occurs if the controller
  does not detect a change in process value following a change in
  output demand after a suitable delay time. Another alarm message
  may be INPUT SENSOR BROKEN (SBr). This occurs if the sensor becomes
  open circuit; the output level will adopt a SAFE value which can be
  set up in Operator Level 3, see section 11.10.

  Two further alarm types are also available. These are:-

  Rising rate of change rrc

  An alarm will be detected if the rate of change (units/minute)
  in a positive direction exceeds the alarm threshold

  Falling rate of change

  Frc

  An alarm will be detected if the rate of change (units/minute)
  in a negative direction exceeds the alarm threshold

  These alarms cannot be configured by the Quick Start Code they
  can only be configured in Configuration Mode, see section 12.3.

  4.4.3 Alarm Indication If an alarm occurs, the red ALM beacon
  will flash. A scrolling text message will describe the source of
  the alarm. Any output (usually a relay) attached to the alarm will
  operate. When configured using the Quick Start Code the relay is
  de-energised in alarm so that an alarm is indicated if power to the
  controller fails. Also using the Quick Start Code alarms are
  configured as manual latching.

  Manual Latching

  The alarm continues to be active until both the alarm condition
  is removed AND the alarm is acknowledged. The acknowledgement can
  only occur AFTER the condition causing the alarm is removed.

  4.4.4 To Acknowledge an Alarm

  Press and (ACK) together.

  If the alarm is still present when acknowledged it is still
  indicated as above. If the alarm is no longer present when
  acknowledged the ALM beacon will go off, the scrolling message
  disappears and the relay is reset.

  To configure any other type of alarm, refer to section 12.3.1.
  These may be:-

  Non latching

  A non latching alarm will reset itself when the alarm condition
  is removed.

  Auto Latching

  An auto latching alarm requires acknowledgement before it is
  reset. The acknowledgement can occur BEFORE the condition causing
  the alarm is removed.

  4.4.5 Auto, Manual and Off Mode

  The controller can be put into Auto, Manual or Off mode see next
  section.

  Auto mode is the normal operation where the output is adjusted
  automatically by the controller in response to changes in the
  process value.

  In Auto mode all the alarms and the special functions (auto
  tuning, soft start and timer) are operative

  Manual mode means that the controller output power is manually
  set by the operator. The input sensor is still connected and
  reading the process value but the control loop is open.

  In manual mode the MAN beacon will be lit, Band and deviation
  alarm are masked, the auto-tuning, timer and programmer functions
  are disabled.

  The power output can be continuously increased or decreased
  using the or buttons.

  ! Manual mode must be used with care. The power level must not
  be set and left at a value that can damage the process or cause
  excess process condition. The use of a separate over-process
  controller is recommended.

  Off mode means that the heating and cooling (or raise/lower)
  outputs are turned off. The process alarm and analogue
  retransmission outputs will, however, still be active while Band
  and deviation alarm will be OFF.

  4.4.6 To Select Auto, Manual or Off Mode

  Press and hold and (Mode) together for more than 1 second. This
  can only be accessed from the HOME display.

  1. Auto is shown in the upper display. After 5 seconds the lower
  display will scroll the longer description of this parameter. ie lo
  op m ode au to m anua l o ff

  2. Press to select mAn. Press again to select OFF. This is shown
  in the upper display.

  3. When the desired Mode is selected, do not push any other
  button. After 2 seconds the controller will return to the HOME
  display.

  4. If OFF has been selected, OFF will be shown in the lower
  display and the heating/cooling (raise/lower) outputs will be
  off

  5. If manual mode has been selected, the MAN beacon will light.
  The upper display shows the process value and the lower display the
  demanded output power.

  The transfer from Auto to manual mode is bumpless. This means
  the output will remain at the current value at the point of
  transfer. Similarly when transferring from Manual to Auto mode, the
  current value will be used. This will then slowly change to the
  value demanded automatically by the controller.

  6. To manually change the power output, press or to lower or
  raise the output. The output power is

  continuously updated when these buttons are pressed

  7. To return to Auto mode, press and together. Then press to
  select Auto.

  WKG.SP WORKING SETPOINT is the active setpoint value and appears
  when the controller is in Manual mode. It may be derived from SP1
  or SP2, or, if the controller is ramping (see SP.RRT or SP.FRT), it
  is the current ramp value.

  Settable between SP.HI to SP.LO

  WRK.OP WORKING OUTPUT is the output from the controller
  expressed as a percentage of full output. It appears when the
  controller is in Auto mode. In a motorised valve controller it is
  the inferred position of the valve For a time proportioning output,
  50% = relay output on or off for equal lengths of time. For On/Off
  control: OFF = 1%

  SP.HI SETPOINT HIGH — High setpoint limit applied to SP1 and
  SP2. Alterable between the controller range limits. These are
  defined in the Quick Code section 4.1.1.

  SP.LO SETPOINT LOW — Low setpoint limit applied to SP1 and
  SP2

  By default the remote setpoint is scaled between SP.HI and
  SP.LO. Two further parameters (REM.HI and REM.LO) are available in
  access level 3 to limit the Remote SP range if required. See
  section 10.1.

  SP1 SETPOINT 1 allows control setpoint 1 value to be adjusted
  Alterable: SP.HI to SP.LO
