Inputs
Tank level switches
(2) Normally-Closed. Can be used with a single level switch.
Inlet pressure switch
Normally-Open.
Pretreat lockout switch
Normally-Open.
The Tank, Low Pressure and Pretreat inputs are 50% duty cycle square wave,
10VDC peak @ 10mA max.
The switch inputs are dry contacts only. Applying voltage to these terminals
will damage the controller.

110-120/208-240 VAC, 60/50Hz (Range: 110-240 VAC)
Permeate Conductivity
0-3000 PPM, 0-6000 μs (standard sensor, CP-1, K=.75)
Feed Conductivity (opt)
0-3000 PPM, 0-6000 μs (standard sensor, CP-1, K=.75)
Output Circuit Ratings
Feed Solenoid
1A. Voltage is the same as motor/supply voltage.
Flush Solenoid
1A. Voltage is the same as motor/supply voltage.
