5.2
Power failure backup with the emergency
accumulator*
To be able to operate the door in the event of a power
failure, an optional emergency accumulator can be con-
nected (see figure
21
). In the event of a power failure,
the change over to accumulator operation takes place
automatically. Throughout accumulator-powered opera-
tion, the operator lighting stays off.
Note
Only the specifically designated emergency accumulator
with integral charging circuit may be used.
5.3
Operation after actuating the mechanical release
If the mechanical release was actuated, e.g. due to a
power failure, the carriage must be re-engaged in the
belt lock before normal operation can be resumed:
• Move the operator until the belt lock in the boom is
well accessible for the carriage, and then stop the
operator.
• Press the green button on the carriage (see figure
6
).
• Move the door manually until the carriage re-engages
in the belt lock.
• Carry out several uninterrupted travel cycles to check
whether the door has fully reached its closed position
and whether it has also fully opened (the carriage
comes to a halt shortly before the OPEN limit stop).
• The operator is now ready to resume normal operation.
Note
The function of the mechanical release should be checked
once a month.
The pull rope with knob may only be
actuated when the door is closed, otherwise, in the case
of weak, broken or defective springs or due to an inade-
quate counterbalance, there is a risk that the door could
close too quickly.
CAUTION
Never hang bodily from the pull rope
with knob!

CHANGING THE LIGHT BULB
When changing the light bulb, the bulb must be cold
and the door closed.
• Pull out the mains plug
• Change the bulb 24 V / 10 W B(a) 15 s (see figure
22
)
• Re-insert the mains plug
• The operator lighting flashes four times

SIGNALS FROM OPERATOR LIGHTING WHEN
MAINS POWER ON
When the mains plug is inserted without the circuit
board button
T
being pressed (with opened light cover),
the operator lighting flashes two, three or four times.
Flashing twice
indicates that no door data is present or has been deleted
(as in the ex-factory state): the learning process can pro-
ceed at once.
Flashing three times
indicates that stored door data is present but that the
last door position is not sufficiently well known. The next
door cycle is therefore an opening reference cycle.
Afterwards, the travel cycles are performed in normal
operation mode.
Flashing four times
indicates that stored door data is present and that
the last door position is sufficiently well known, so that
travel cycles in the normal operation mode can take
place at once, using the impulse sequential control
(OPEN-STOP-CLOSE-OPEN etc.) (normal behaviour
after completing the learning process and following a
power failure). When a power failure has taken place in
the middle of a travel cycle, for safety reasons the first
impulse generated always causes the door to open.

ERROR MESSAGES
Error messages / diagnostic LED
(LED, see figure
8.1
)
When operation does not go to plan, the causes can be
easily identified via the diagnostic LED which is still visible
even with the light cover closed. In the programmed
state, this LED normally glows constantly and goes out
as long as an externally connected impulse is pending.
LED:
flashes 2 x
Cause:
Photocell was interrupted / not connected
Remedy:
Check photocell, connect or replace as
necessary.
LED:
flashes 3 x
Cause:
The CLOSE force limit has been activated –
a safety return has taken place.
Remedy:
Remove the obstruction. If a safety return
has taken place for no obvious reason, check
the door mechanics. It may be necessary to
delete the door data and repeat the learning
process.
LED:
flashes 4 x
Cause:
The static current circuit or wicket door
contact is open or was opened during a
travel cycle.
Remedy:
Check the connected unit, close the electric
circuit.
LED:
flashes 5 x
Cause:
The OPEN force limit has been activated –
the door has come to a halt while opening.
Remedy:
Remove the obstruction. If the door has
come to a halt for no obvious reason, check
the door mechanics. It may be necessary to
delete the door data and repeat the learning
process.
LED:
flashes 6 x
Cause:
Operator fault / malfunction in the operator
system.
Remedy:
It may be necessary to delete the door data.
If the operator fault re-occurs, replace the
operator.
