    If the device connected to the mA output is out of calibration, and cannot be calibrated, then the low and high current levels can be trimmed by altering P838 (Low Trim) and P839 (High Trim). To do this, simply enter the value that ensures that 4 mA or 20 mA respectively are shown on the remote device.

  • Page 26: Alarm Relay Set-Up

    There are three types that each relay, individually, can be set to, for example, consider Relay 1, you can select parameter P210 from the following options: 0 = Not in Use relay will remain in the de-energised condition. 1=Alarm: relay will de-energise to set the alarm “ON”. 2=Control relay will energise to set the control “ON”.

  • Page 27: Control Relay Set-Up

    Control Relay Set-up The control relays are energised to turn the control “ON” (start process function), and de-energised to turn the control “OFF” (stop process function). In this way, loss of power will ensure that the pumps are turned “OFF”. To set a control relay, set the first parameter for the relay to equal 2 (for control).
