MASTER VALVE ON/OFF SELECTION
Most domestic irrigation systems operate from a town water system, or a bore or a dam
(see Introduction).
The irrigation controller has a Master Valve output which is used to control a Master Solenoid Valve
when operating with a town water supply. The use of a Master Valve is highly recommended, particularly
if the pipe connections to the Station Valves are done using PVC push on and clip connections which are
prone to bursting open when continuously subjected to mains water pressure.
When using water from a bore or a dam, the Master Valve control line is used to control a Pump Start
Relay. The pump must be turned on with each individual Station Valve.
The default setting for the Master Valve is OFF. It must be turned ON for each individual Station.
To program the Master/Pump Start valve:
1 Select SET AUXILIARIES on the Control Dial.
2 Press the button once and the PEr screen
will be displayed.
3 Press the button again and STATION No
will be flashing and PUMP will show as OFF.
4 Press and OFF will flash.
5 Press to change to ON. Pressing will
return to OFF.
6 Press and the Station No will flash.
7 Use the and buttons to select another
Station No and repeat steps 4 and 5.
8 Repeat steps 6 and 7 until all Master Valve
programming has been completed for all
Stations.
PUMP DELAY
The pump delay feature can be used to allow the recovery of a bore water supply by delaying the
opening of Station valves. This allows the pump to operate against a closed head for a programmed
period of time, pressurizing the main line. This can be useful where draw down can occur in a bore.
Dierent delays can be set for each Station and the value can be between 0 (OFF) and 99 seconds.
Warning
This irrigation system allows the operation of a pump against a closed head (no valves open). This
has the potential to cause damage to the pump, pipes and other components in the irrigation system,
resulting in explosion, and should be used only in consultation with a hydraulic engineer.
