5.1 Troubleshooting Controller
1. To test the controller’s output, connect a solenoid to one of the controller’s
red and white wire pairs. Institute a test run via the handset with one
(1) minute on the station in question and zero (0) minutes on the other
station. If the solenoid is not installed, verify that the plunger retracts and
extends or that you hear the sound of the plunger latching. If the solenoid
is installed onto a valve, see that the valve turns on and the sprinklers or
drip system is working. If it does not turn on, the plunger does not retract
and extend, or no sound is heard of the plunger latching, repeat the process
using a second solenoid. If the problem continues you may have an issue
with the controller wires and the
WATERPROOF CONNECTORS
.
2. The LEIT-2ET controllers function only with S-305DC solenoids or
305DC-XXX valves.
3. The LEIT-2ET controllers function only with compatible sensors (HUNTER
MINI-CLICK or RAIN BIRD RSD).
5.2 Troubleshooting Solenoids
1. Verify that the correct solenoid and adapters are being used for the valve in
question.
2. Verify that the white and red wires from the solenoid are connected to the
white and red wire pair on the controller and that these splices are tight
and corrosion free.
3. Verify that no water is leaking externally near the adapter, stem, or bonnet.
4. Verify that all O-rings and/or rubber hoses are in place; if in doubt check the
adapter and the solenoid.
a. To test S-305DC solenoid, remove the solenoid from the valve and
disconnect the hot and common wires. Verify the solenoid functions
properly using a 9-volt battery by briefly touching the wires to the
positive and negative contacts. Reverse polarity if nothing happens.
Plunger should retract. Reverse polarity to close (plunger should extend
and a sound of the plunger latching should be heard).
