LOW VOLTAGE CONNECTIONS
The low voltage connections are found on the low voltage (front panel) board (
Fig. 7
).
Use 22-24 AWG (,76 mm²) wire for: interlock, drum levels, dry alarm, and water meter connections.
These signal wires must be run separate from AC power lines.

Low voltage signal wires, e.g., water meter, must be run separate from AC power lines.
Sensor (probe) Connection Input
The controller may be supplied with a Stainless conductivity sensor. Connect the wires to “Sensor
In” as shown
(Fig. 7)
.
* If you are using a sensor without temperature compensation, place a jumper wire
between the GRN and WHT connections in the SENSOR IN terminal block.
