SWITCH DOES NOT RESPOND
Error:
The key switch or programming switch isn’t working; the system isn't working and
doesn’t respond when button is pressed or key is used.
Troubleshooting:
1. Is the transformer mains plug connected?
If not, connect the mains plug
If yes, continue to point 2.
2. Is the mains switch on the transformer switched on?
If not, switch on the mains switch
If yes, continue to point 3.
3. Is the mains switch on the transformer lit up green?
If not, check supply cable to the transformer
If yes, continue to point 4.
4. Is the LED on the transformer lit up green?
If not, continue to point 5.
If yes, continue to point 7.
5. Is the transformer fuse defective? (‘TRANSFORMER AND MOTOR FUSE’ section)
If not, continue to point 6.
If yes, replace the fuse (a spare fuse can be found in the transformer cover);
continue to point 6.
6. Is the LED on the transformer lit up green now?
If not, please contact Rollo Solar
If yes, continue to point 7.
7. Read and make note of error messages on the circuit board, then perform reset
Switch off the transformer mains switch for at least 10 seconds; this will confirm all
errors!
8. Has the error been corrected?
If yes, check that the system works by running ‘AUF’ (OPEN) and ‘ZU’
(CLOSED) at a minimum
If not, please contact Rollo Solar
