Winch motor will not run:
Is mains voltage supplied to terminals F1 and F2?
Battery lamp is not lit, in spite of OK mains voltage:
Is there approx. 24V DC on terminals F5-F6?
Battery lamp not lit by uninterrupted 230V (battery operation):
Is approx. 18V DC supplied to terminals F5-F6?
Winch motor is not running when mains voltage is disconnected:
If not, check:
- external TEST supply separator
- mains voltage selector
- installation fuses
- fault current relay
- AUT-MAN switch of the winch motor
- wire connection to motor lid
If not, check:
- panel wire connection
- external 24V installation on F5-F6
If not, check:
- battery wires
- panel wire

- battery voltage.
The system requires 24V DC winch motors. Furthermore, the motors must
be able to open at maximum load as low as 15V DC, as the system works
using an 18 V battery. This is not normally a problem for ordinary 24V DC
winch motors.
