Inspection and Maintenance9
Door inspections and maintenance9.1
WARNING
Danger of injury due to defective safety components
Important safety components may fail or become defective
if not sufficiently inspected and maintained.
Have a qualified person perform inspection and
maintenance work at regular intervals.
The following inspection and maintenance tasks must be
carried out by a specialist in accordance with these
instructions, before initial operation and at least once a year
(or every 6 months if there are more than 50 door cycles per
day).
Inspect all load-bearing components9.1.1
WARNING
Danger of injury due to high cable tension
Cables are under high tension. Damaged cables may be
expelled and result in serious injuries.
Fix the door leaf to prevent movement before
exchanging damaged cables.
Be particularly careful when exchanging damaged
cables.
Check load carriers (cables, springs, tracks, supports)
and safety devices for breakage and damage, replacing
any damaged components as necessary.
Weight counterbalance9.1.2
WARNING
Danger of injury due to uncontrolled door drops
If the counterbalance has not been properly adjusted, this
may result in an uncontrolled door drop, which could trap
persons or objects.
Retighten the tension springs.
High spring tension
Springs are under high tensile stress and may be expelled
from the product if they are not secured during tensioning.
Fix the door leaf to prevent uncontrolled movement
before adjusting the tension springs.
Check the counterbalance of the door leaf
Open the door manually up to the half-way point.
The door must be capable of holding this position.
If the door clearly drops down, retighten the tension
springs.
Fixing points9.1.3
Check all the fixing points on the door and the building
structure and make sure that all the fastenings are
securely seated and, if necessary, retighten.
Rollers and tracks9.1.4
When the door is closed, the rollers must be easy to turn.
Adjust the tracks, if necessary!
Clean tracks, if necessary,
do not grease!
Hinges and roller holders9.1.5
Oil hinges and roller holders.
Seals9.1.6
Check for damage, deformations and completeness. If
necessary, replace.
Operator inspections9.2
The garage door operator is maintenance-free. An inspection
or required maintenance may only be carried out by a qualified
person. Contact your supplier for this purpose. A visual
inspection may be carried out by the operator.
Check all safety and protective functions monthly to
ensure that they are in working order, and immediately
rectify any malfunctions and/or defects, if necessary.
Checking the tension of the toothed belt9.3
Check the tension of the toothed belt every six months
and adjust, if necessary (see figure 9.8).
During the start-up and slow-down phase, it is possible that
the belt will briefly hang out of the boom profile. However, this
does not result in any technical consequences and does not
negatively affect the function and service life of the operator.
Operator light messages10
If the mains plug is plugged in without the T button having
been pushed, the operator light will flash two, three or four
times.
Two flashes
No door data is present or the door data has been deleted
(delivery condition); it can be taught in immediately.
Three flashes
Saved door data is present, but the last door position is not
sufficiently known. The next run will be an OPEN reference
run. Thereafter, normal door runs will follow.
Four flashes
Saved door data is present and the last door position is
sufficiently know, i.e. normal door runs can proceed
immediately (normal behaviour after a successful teach-in or a
power failure).
Malfunctions and Troubleshooting11
Error messages/diagnostic LED11.1
(Red LED on the operator cover)
The red LED helps to easily identify causes when operation
does not go according to plan. In normal mode, the LED lights
up continually.
NOTE:
If normal operation of the garage door operator with the radio
receiver or the T button is otherwise possible, a short circuit in
the external button‘s connecting lead or in the button itself
can be recognised through the behaviour described here.
