4. Setting up the controller
4.1 Setting up the controller
The controller is supplied set up as follows:
-
230V mains supply.
-
Capacitance probe input (voltage).
-
Reducing output with increasing input.
-
4 - 20mA output.
-
Wave filter position 1 (minimum damping).
4.2 To change the mains supply voltage:
-
Unplug the controller from its base.
-
Remove the rear cover panel.
-
Slide out the printed circuit board.
-
Slide the voltage selector switch to the 115 V setting.
-
Replace the printed circuit board.
-
Ensure that the LEDs engage with the holes in the front panel.
-
Replace the rear cover panel.
4.3 To change the function settings:
-
Unplug the controller from its base.
-
Remove the rear cover panel.
-
Slide out the printed circuit board.
-
An 8-way switch on the printed circuit board determines the controller functions.
-
Set the switches to the positions shown in Figure 3 for the chosen functions.
-
Replace the printed circuit board.
-
Ensure that the LEDs engage with the holes in the front panel.
-
Replace the rear cover panel.
Note that Switches 4 and 5
are not used.
4.4 Current / voltage input - Switches 1 and 2
The controller is supplied set for use with a capacitance probe, (voltage input), with Switches 1
and 2 OFF.
If a current input is required, for use with a 4 - 20 mA transmitter for example, set Switches 1 and
2 to ON.
4.5 Reverse acting output - Switch 3
The controller is supplied set so that a rising level at the probe will give a falling output from the
controller, with Switch 3 OFF.
If a rising controller output is required with a rising input, as when using a differential pressure
transmitter for level monitoring, set Switch 3 to ON.
4.6 4 - 20 mA / 0 - 20 mA - Switch 6
The controller is supplied set for 4 - 20 mA output, with Switch 6 OFF.
Set this Switch to ON for 0 - 20 mA output.
