Introduction
The Holman Cable & Solenoid Seeker is designed to allow the user to track low
voltage cables used for garden and landscape automatic watering systems,
and also low voltage garden lighting systems.
It can also be used to trace other cables.
Any cable carrying voltages above 30 volts should be traced by a licensed
electrician.
The system uses a “transmitter” to send a signal down the cable being traced
or to a solenoid valve that is being located.
A “receiver” is then used to pick up the signal and follow the cable or locate
the coil.
A. Battery Test
To test the Transmitter battery, set switch to “Battery Test” position and set
the output to maximum. The power LED will light up. Short the alligator clip
leads together. The Status LED will light up - a bright Status LED indicates an
acceptable battery condition.
To test Receiver battery, push the transmitter switch to “Cable Scan” position.
Then set the ON / OFF Reciever switch to ON position, place the antenna next
to the Transmitter. An audible tone indicates an acceptable battery level.
B. Transmitter Connection
To locate a cable follow the following procedure:-
1) Connect the transmitter to the cable you are looking for. If the cable is
connected to an irrigation controller, disconnect the cable from the controller
and clip the RED alligator clips from the transmitter onto the solenoid cable.
2) The BLACK alligator clip should be connected to an independant grounded
earth. The easiest way to do this is to connect it to the blade of a screw driver
pushed into the ground (preferably wet ground). You may require to connect
via a short length of cable.
If it is inconvenient to connect to an independently grounded earth, remove
the valve common cable from the controller and connect the BLACK alligator
clip to this cable.
3) Move the transmitter switch to the “Cable Scan” position.
