  Table 1 - Specifications

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.

Controller Power 

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.

Motor 

1.0 HP/110-120V, 2.0 HP/208-240V.

Circuit Protection

Relay Fuse  

F1 5x20mm   -   2 Amp   -   BelFuse 5ST 2-R

 

Note: The fuses shown above are for supplemental protection only. Branch 

circuit protection and disconnect means must be provided externally.

 

See Field Wiring Diagram for Branch Circuit protection requirements.

Other

Dimensions 

7" tall, 7" wide, 4" deep. Nema 4X Polycarbonate Hinged Enclosure.

Weight 

2.6 lb. (Basic Configuration, not including optional wire harness, etc.)

Environment 

0-50°C, 10-90%RH (non-condensing)

 

Note: After our modifications the enclosure rating is Nema 1.
