F
ERROR LED flashing slowly
•alarm in progress: connect the SD-Keeper to find the alarm and take the appropriate action (see the
diagnostics guide)
G
door locked and ERROR LED
ON
•SETUP must be executed
•alarm in progress: connect the SD-Keeper to find the alarm and take the appropriate action (see the
diagnostics guide)
•check motor connection
•check motor encoder connection
•check the condition of the encoder connection flat cable
H
door NOT executing SETUP
and ERROR LED flashing
slowly
•SETUP execution impeded (see 940SDM control board instructions)
I
door NOT CLOSING and
ERROR LED off
•photocell/s engaged
•make sure that the selected operating function is not DOOR OPEN (if no SD-Keeper is installed, make sure
that input 8 of the J6 terminal board is not jumper connected to the negative)
•make sure that the selected operating function is not MANUAL
•check motor connection
•check if power is being supplied to the motor (VMOT LED ON)
L
door NOT OPENING and
ERROR LED off
•make sure that the selected operating function is not MANUAL
•make sure that the selected operating function is not NIGHT (if no SD-Keeper is installed, make sure that
input 7 of the J6 terminal board is not jumper connected to the negative)
•check motor connection
•make sure that the lock is not locked
•check if power is being supplied to the motor (VMOT LED ON)
M
