In this case, a fault condition will exist until manually cleared by the operator. During SETUP,
assign which programs (1-4) will utilize the pump during irrigation.
WARNING: ALWAYS TURN-OFF POWER before changing or modifying field, senor
or power wiring within the controller. Dangerous voltage and current exist
within the controller which may damage the controller if improperly
connected or shorted.
3.2.2 Flow Sensor Installation
Install the Flow Sensor in the Main Line as depicted in Figure 10 - Flow Sensor Electrical
Connections, making sure that there are at least 10 pipe diameters upstream and 5 pipe diameters
downstream of the sensor from any valve, reducer, elbow, or other obstruction or device which may
cause turbulence in the water flow. As an example if the pipe is 2 inches in diameter, then 10 pipe
diameters would be 20 inches before the sensor and 5 pipe diameters would be 10 inches after the
sensor.
Observe the proper direction of flow according to the flow indicator (arrow) on the sensor body.
Install a valve box around the sensor and make the electrical connections inside the box. Use
waterproof wire nuts for all splices.
The use of Rain Master EV-CAB-SEN or other shielded cable is required to ensure proper
operation. Polarity must be observed when connecting the sensor to the controller.

WARNING: ALWAYS TURN-OFF POWER before changing or modifying field, senor
or power wiring within the controller. Dangerous voltage and current exist
within the controller which may damage the controller if improperly
connected or shorted.
EXAMPLE: FOR 3" FLOW SENSOR, DIMENSION ‘A’ MINIMUM 30" DIMENSION ‘B’ MINIMUM 15"
