If an alarm occurs, the TDS / Bottom Blowdown Valve status will not show. ‘ALARM’ will be shown first followed by the type of alarm. See Section 9 – ‘Fault finding’ for types of errors. Example of alarm status: 7000 PPM 7000 ALARM 7000 HIGH TDS If a bottom or

Error message Cause Action 1 Powerout There has been a loss of power to the product during operation. 1. Remove power from product. 2. Check that all wiring is correct. Power fail. 3. Check that the power supply is secure, i.e. does not suffer from ‘brown outs’ 4. Reapply power. 5. Press OK to Clear. 2 SETUP MENU TIME OUT The operator has entered the commissioning mo

Displays the calculated water resistance in ohms, Kohms or Mohms. Not visible if no Pt100 is fitted. Displays the equivalent operating temperature, measured by the Pt100 (if connected). Displays the equivalent calculated Cell or Probe Factor, indicating the condition of the probe. Shows if the bottom blowdown switch is OPEN or CLOSED (if connected).

If no Pt100 is fitted, a constant temperature can be entered. e.g. 184 °C (default). Allows selection of all the TDS control features: Sensor type, purge, filter, range, set point, hysteresis, calibration, and calibration interval. 6.4.5 INPUT – TDS sub-menu INPUT TDS SENSOR INPUT TDS PURGE INPUT TDS FILTER I

• IM-P403-89 EMM Issue 8 16 3.3.2 Purge output Used only when the probe is mounted in the blowdown line, Purge ensures the sensor measures the conductivity at boiler temperature. The purge duration time is the time the valve is open to enable a representative boiler sample to reach the probe. A purge occurs every PURGE — INTERVAL time either independent of burner firing, or dependent on cumulative boiler firing time. Fig. 7 Output with purge time set (>0s) 3.3 Outputs 3.3.1

• IM-P403-89 EMM Issue 8 38 6.3 Commissioning — Quick set-up This section allows the user to carry out the minimum commissioning necessary to operate the system. It accepts the defaults set in the factory, so will only work if the original default settings have not been altered. See the default settings in Section 10, Technical information, to confirm. Settings can then be tailored to suit the individual requirements of the customer / application if required. Warning: — It is essential that you comply with

• IM-P403-89 EMM Issue 8 54 8. Maintenance Note: Read the ‘Safety information’ in Section 1 before starting any maintenance. No special servicing, preventative maintenance or inspection of the product is required. During installation or maintenance, the rear of the product must be protected from environmental pollutants entering the product. Alternatively, the tasks can be performed in a dry clean environment. 8.1 Cleaning instructions Use a cloth dampened with tap / de-ionised water or isopropyl alcohol. Use of other

• IM-P403-89 EMM Issue 8 15 3. System overview 3.1 Function The controller has an adjustable alarm and set point levels. The product can be configured to control TDS / conductivity of water. Once fully commissioned, the TDS value is displayed in μS / cm (or ppm if selected). Note: Conductivity is expressed in parts per million (ppm) or micro Siemens per centimetre (µS / cm). Micro Siemens / centimetre is becoming the more common unit, and is therefore the default setting. If the water conductivity exce
