Maintenance and care
Disconnect the opener from the power (switch off the cir-
cuit breaker to the opener or disconnect the fuse on the
circuit supplying the opener with voltage) and check to be
sure no voltage is present.
Remove coarse dirt from the C-rail.
The chain must be cleaned with a lint-free cloth and then
lubricated with an electrically conductive lubricant
(WD-40).
Never oil or grease the chain. This can lead to a malfunc-
tion caused by insufficient electrical contact.
Plug in the power plug into the power outlet
or
Switch on the the electrical supply for a direct electrical
connection (switch on the circuit breaker or fuse).
Checking the power cut-off
DANGER
There is the possible risk of injury or death if the automatic
power cut-off is not functioning. Persons can become
clamped, jammed or pinched by a closing door that does not
stop after it has encountered an obstacle.
The door must change directions after contacting a 1”
(25.4 mm) high object on the floor.
Check the power cut-off monthly.
Open the door with the drive.
Place an object such as a 1” (25,4 mm) high piece of ply-
wood centered in the running path of the door.
Close the door with the drive.
When the door contacts the object it must stop immediately
and open completely.
If the door does not open, the drive is defective and must be
repaired or exchanged. Consult your specialist dealer for advice.
Testing the photoelectric barrier function
Close the door with the drive.
Interrupt the photoelectric barrier during the closing proce-
dure. Hold a 6” x 1 (152mm x 305mm) white object in the
middle of the infrared beam between the transmitter and
the receiver.
The door must stop immediately and then subsequently
open completely.
If the door does not stop, check the following:
– if the housing of the photoelectric barrier is dirty,
– if transmitter and receiver are correctly aligned with
each other,
– if the photoelectric barrier functions correctly: If no
object or person is between the transmitter and receiver,
the LED (1) on the transmitter and receiver must be per-
manently lit. If this is not the case, see chapter Trou-
bleshooting “Fault indicators photoelectric barrier”.
– if the cables are damaged or loose.
