3.2.1.3.1 Simultaneous Use - Normally Open Master Valve and Pump
If you have a Master Valve which is Normally Open until energized and you utilize a pump,
connect the solenoid to the MV and Master Valve Common terminals and the Pump to Station 1
as depicted in Figure 9 - Normally Open Master Valve and Pump.
During configuration SETUP, select valve type Normally Open (NO). The Master Valve will
only be activated when the controller detects a Main Line Break fault or an Unscheduled Flow
condition.
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.
!
ALWAYS TURN-OFF POWER before changing or modifying field, sensor 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.
