- Troubleshooting Guide
Note ;Always switch off the power supply before attempting to repair the door or control system.!
Faulty operation -- Red indicator LED is off - see 17.1.
Faulty operation -- Red indicator LED is on - see 17.2
Faulty operation -- Red indicator LED is flashing quickly - see 17.3
Faulty operation -- Red indicator LED is flashing slowly - see 17.4
Remote control transmitter problems - see 17.5
17.1 Faulty operation, the Red indicator LED is off. This indicates a power failure problem.
Check the power supply is live at the socket outlet.
Check the fuse in the 13a plug and fit a new 5A fuse if necessary.
Check both control board fuses, spares are supplied, fitted to the control unit cover. The main PCB fuse is a T 5 A 250 V [dia 5 mm x
20 mm , --see Fig 3]. The control PCB fuse is a T 500 Ma 250 V [dia 5mm x 20 mm , -- see Fig 3]
Check the security of the mains power cable at terminals L,N and E. If no fault is found, repair or replace the control board.
17.2 Faulty operation, the Red indicator LED is on. This indicates a possible problem with the motor drive.
Temporarily switch on and check the control board status LED -- if this is green:- The motor thermal trip may have operated. wait ten minutes
for the motor to cool down. Switch off and check the security of the motor cables at terminals E,L1,L2 and N3.
Check the motor drive and limit switches.If the control board status LED is red ;- Check the security of the link wire interconnecting terminals
Com & Stp [if fitted]. If a stop control device is fitted, check the operation and condition of cables connecting this to terminals Com & Stp.
17.3 Faulty operation , the Red indicator is flashing quickly. This indicates that the safety circuit is active.
Clean the photoelectric sensor and reflector.
Check the alignment of the safety beam.
Check the condition of cables connecting sensor[s] to terminals Ve, +Ve, S1 & S2. If a single photoelectric sensor is fitted check the
security of the link interconnecting terminals S1 & S2.
Operate the door using the photocell override procedure see section 12 and if necessary renew a damaged sensor or reflector.
17.4 Faulty operation , the Red indicator is flashing slowly. This indicates that the self-test diagnostic circuit has activated.
Check that terminals Com & Stp are interconnected using a link wire or stop push button before switching the mains power supply on.
Check that operating button next to the Red LED “clicks” when pressed.
Check for short circuits in any control devices or cables connected to terminals Com, Imp, Opn and Clo. [if fitted].
The photoelectric sensor may be faulty disconnect sensor[s] and temporarily bridge terminals -Ve & S1 and S1& S2.
Switch off the power supply for 5 seconds and re-power the unit to reset the system. If no fault is found, repair or replace the control
board.
17.5 Remote control transmitter problems.
The red LED on the hand set should illuminate when the button is pressed, if it does not- replace the battery in the transmitter. If the
LED is dim the battery is low and the operating range will be reduced.
