9. Maintenance

1) Check the sensor output voltages.
2) Make sure that the cables are flexible.
If not, please return to our factory.
3) If motor or valve does not operate while Control LED is on,
short the control terminals with a piece of wire.
If it runs, it is controller problem.
If not, wire is disconnected somewhere.
4) If motor or valve does not stop when Control LED is off,
check if wires are disconnected from control terminals.
If motor stops, it is controller problem.
5) If the power indicating LED lamp is off, see if the fuse is OK
(100mA, 250V AC)
6) For multi-wire controllers, disconnect the jumper from COM.
Then, check controller output by shorting terminals one by one
such as low alarm, stop, start and high alarm.
