Trouble Shooting Instructions
Winch motor will not run:
Is mains voltage supplied to terminals F1 and F2?
If not, check:
- external TEST mains disconnector
- mains voltage selector
- installation fuses
- fault current relay
- AUT-MAN switch of winch motor
- wire connection to motor lid
Battery lamp is not on, in spite of OK mains voltage:
Is there approx. 24V DC on terminals F5-F6?
If not, check:
- panel wire connection
- external 24V installation on F5-F6
Battery lamp is not on when 230V is disconnected (battery operation):
Is approx. 18V DC supplied to terminals F5-F6?
If not, check:
- battery wires
- panel wire
- fuses (spare fuses)
- battery voltage.
Red lamp is on:
When emergency operation is active (red lamp is on), and there is a break in the
emergency opening (green opening lamp is off), the DA 75 winch motor
cannot be operated in manual mode with the AUT/MAN switches on the
winch motor.
Manual operation is possible when the DOL 278AT temperature button has
been turned to TEST so that the green lamp in on constantly
Winch motor is not running when mains voltage is disconnected:
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 18V battery. This is not normally a problem for ordinary 24V DC
winch motors.
