10.3.1 Malfunctions without error messages
Error Cause Solution
LED 8 does not light up.
LED 8 does not flash in
stand-by mode.
- No voltage. - Test accumulator voltage (approx. 24V).
- Check fuse in charge regulator (only solar version).
- Check if all connections are correct.
- Module antenna not plugged in. - Plug in module antenna (point 8.1).
- Control unit defective. - Have operator system checked.
Operator system beeps and
flashes when connecting the
accumulator unit.
- Voltage control is active. - Charge accumulator unit completely and then connect it to
the operator system (observe sequence for solar version).
- Voltage control too sensitive. - Have operator system checked.
- Accumulator unit defective (too old or
damaged by total discharge).
- Exchange accumulator unit.
Operator system beeps and
flashes during operation.
- Accumulator voltage too low. - Charge accumulator unit completely
(Pay attention to the display on the charger).
Operator system does not
switch from stand-by mode
to operating mode.
- Wrong operating element actuated. Only the following operating elements switch the operator
system to the operation mode:
- Radio control, external contact at terminal XP02,
programming button P
- Control unit defective. - Have operator system checked.
Operating range too low. - Interferences or shielding. - Install module antenna externally with the optional adapter.
Accumulator unit is not
charged by solar power
(only solar version).
- Wrong connections. - Check connections. Always observe connection sequence
to the charge regulator.
- Solar module does not supply power. - Check connections (The idle voltage at daylight is approx.
30 - 45 V without charge regulator, approx. 28 V with
charge regulator).
No reaction on impulse. - Connecting terminals for "impulse"
button bridged (e.g. by short-circuit in
cable).
- Separate for test reason possibly connected key switches or
interior push buttons from the control unit (point 6.10).
- Socket XB20 in stand-by mode without function.
No reaction on impulse from
hand transmitter.
- Module antenna not plugged in. - Connect module antenna with control unit (point 8.1).
- Hand transmitter code does not
correspond with receiver code.
- Check coding (point 8.5.3).
- Activate hand transmitter again (point 8.5.3).
- Empty battery of hand transmitter. - Insert new battery 3V CR 2032 (point 7.1).
- Hand transmitter or control electronics
or module antenna defective.
- Have all 3 components checked.
