CONNECTION INSTRUCTIONS
3.2 Emphasis concerning the solenoids extension wire.
The extension wire carries only 24 Watt power.
·
The number of leads in the extension wire must be at least that of the number of valves
intended for operation plus two more: one for the Master- valve and one for a common
wire. For more convenient connection, it is recommended to use a cable having differently
colored leads.
·
It is recommended to use a cable having extra leads for when a valve is added or when
a lead becomes faulty.
·
The minimum thickness of the wires in the extension wire leads should be 0.5 mm. Where
the valves are situated at a distance of more than 100 meters from the controller, you
should consult Galcon as to the desirable thickness of the wire.
·
The extension wire should be laid in an orderly manner, - with the help of nail clasps where
on a wall, or if underground, - within a suitably protected pipe-line.
·
It is preferable not to use cable joins. If it becomes necessary however, the sections
should be connected through protected connection-boxes.
·
The extension wire should be connected to the valves with electrical-connectors within
a protected connections- box, (not included). It is desirable that the number of connection
points in the box should exceed the number of valves.
3.3 Connection of the Solenoid leads, power source and sensor.
Before connecting the controller to the power source, the valves should be attached to the
controller. The explanation and diagram No. 5 below will assist.

PLEASE NOTE
The regular mode of sensor-entry is NC. Connection to the sensor is blocked by
a metal bridge. In order to install the sensor the bridge must be removed from
the connections board. In order to re-block the sensor, the bridge should be re-
installed. Should the bridge be lost, the sensor’s exit can be fused with the aid
of regular electric wire.
