of the door panel. When the motor is discon-
nected, the door panel should be balanced
in any position. Only disconnect the motor
when the door is closed. This must be done
by a qualified engineer if the motor powers
the shaft directly or indirectly. Only if the
electrical drive is equipped with a quick-
release coupling and the door with a spring
break protection, you should check the
balance yourself. Even then, the door must
be completely closed before you can dis-
connect it.
There are different control unit models,
depending on the motor type. For detailed
information about the electrical drive, see
the manual supplied with the motor.
4.2
Open/close using a manual chain
hoist
With the manual chain hoist model the shaft
(using cable drums and balance springs) are
manually driven. A unit with a circular chain
has been installed at the end of the shaft.
This control chain hangs in a loop next to the
door. Depending on the direction of move-
ment of the chain, the door panel moves up
or down. To open/close using a manual
chain hoist:
• Take one side of the loop in each hand.
• Pull one side of the chain downwards.
• If the door panel does not move in the
desired direction, then pull the other
side down.
• With the other hand, keep grabbing
hold of the chain.
• Do not let go of the chain while the door
is moving.
• Move (control the movement speed by
using your free hand to slow down the
part of the chain that is moving
upwards).
• Then fasten the chain with the chain
holder.
Do not fasten the chain in order to rectify a
poor balance of the door panel. If the door
automatically opens further or closes, then
have the balance springs adjusted by a
qualified engineer. If the chain starts slip-
ping, contact your maintenance company.
The door can only be operated from the
inside with the manual chain hoist.
This user manual must be given to the customer and must be kept within easy reach during the entire period of use.
Note!
Never operate the door any other
way since the directional chain may
cause a dangerous situation.

4.3 Open / close with pull-cord
With this operating system, the door panel is
powered manually.
To open:
• use the door handle or the pull-cord to
pull the door upwards.
• Make sure the door has sufficient
momentum for it to swing up to the
required height.
To close:
• pull the pull-cord to move the door
downwards again. Only operate the
door panel with the handle or with the
pull-cord. Do not use wheel brackets,
stabilizers, and sliding bolt as a handle
to move the door panel.

Locks

5.1

Sliding bolt

The sliding bolt can be used to lock the
overhead door from the inside.
5.2

Outside lock

The outside lock can be used to lock the
overhead door both from the inside and
outside. A lock in combination with an
electric drive must be equipped with a
switch to prevent the motor from switching
on when in a locked position. Tip for easy
locking and unlocking: Place your foot in the
handle to push the door panel all the way
down.
6

Access door

Make sure that the access door is closed
when opening and closing the overhead
door. The electric control can only be
operated when the access door is closed
English user manual
(see 6.5 access door switch). Under the
access door there is a high or low threshold.
7

Improper use

A change in the weight of the door panel will
disrupt the balance of the overhead door:
Never place objects against the door panel
or against the guide rails. Never attach
added weights to the door panel. Never use
the door as a hoist.
Stabilizing profiles and wheel brackets are
not suitable to stand on:
Never climb up on the door panel.

Safeguards
Depending on the model, an overhead door
can be equipped with the following safety
features:

8.1 spring break protection

8.2 anti-drop device

8.3 Safety Bottom Edge

8.4 access door switch

8.5 slack cable switch
8.1
Spring break protection
The spring break protection activates if the
balance spring breaks. The shaft with cable
drums is secured so the door panel cannot
move. The door can be operated again after
the broken spring has been replaced.
8.2 Cable break protection
The anti-drop device kicks in if the steel
cable breaks. The door panel is then
secured to the rails, making it impossible to
move the door panel. The electric drive (if
present) is automatically switched off.
Warning
Disengaging an activated spring break
or cable break device must only be
carried out by a qualified engineer.
+ WARNING +++ WARNING +++ WARNING +
With electrically powered doors this switch
also ensures that if the cable tension is low,
the motor is switched off. This will prevent
the steel cable from unwinding from the
drum. Never cut the steel cable if the door
panel cannot be operated.
8.3 Safety Bottom Edge
(only possible in combination with an
electrically operated door) The Safety
Bottom Edge automatically switches off the
motor if the bottom seal makes contact with
an obstruction.
