TROUBLE SHOOTING GUIDE
Normal operation (both LED Lights ON):
GREEN LED ON – Power ON (every second a short flash of the LED)
RED LED ON – OUTPUT SIGNAL (continuous random flashing)
Status shown by the two LED lights
NO GREEN, NO RED (No operation)
•
For DC units, check DC supply and any fuse or circuit breaker fitted.
voltage should be 24vdc (range 24 – 32vdc)
•
For AC units, check AC power supply and any fuse or circuit breaker fitted.
voltage should be 100 – 240vac (50/60Hz)
GREEN flashing : one flash followed by ON for 3 seconds. Input voltage to the PCB is low.
•
For DC units, check the DC supply at source. Check condition of cable and
connections.
•
For AC units, the internal Power Supply (AC-DC transformer) requires testing for
correct operation and the output delivery of 24vdc to the PCB.
GREEN flashing : two flashes followed by ON for 3 seconds. Overload on output.
•
Check the plugs and cables of the transducers for possible damage / short circuits.
•
Connect only one transducer and cable at a time to identify suspect parts.
•
Run the control unit without any transducers connected, it should operate
normally. If it does not operate without fault, please contact your supplier.
NOTE: DO NOT run for more than 5 MINUTES without transducers connected.
GREEN flashing : flashes on/off every half second. Temperature too high, above 80
o
C.
•
Check the electrical fan is working.
•
Check the two vents (upper and lower) for blockages / obstructions.
•
Check the ambient temperature of the control unit’s location.
