MALFUNCTION DIAGNOSIS
Problems
Causes
Solutions
The door does not move.
1.
Power failure.
Make sure the door is receiving power supply.
2.
Door stuck.
Separate the door from the belt and check if the leaves move by hand without any problem.
3.
Blown fuse.
Check the M1201 fuse state on the switch (page 14A) and replace it if necessary.
4.
Disconnected cables.
Make sure that all the cables are well connected.
The door opens and
closes with a low speed.
1.
Leaves with friction on the guides.
Make sure that the leaves have the necessary clearance on the guides or if they are squeezing the glass (1mm).
2.
Carts with damaged bearings.
Separate the belt from the door and move the it manually. Replace the carts if these are damaged.
3.
Belt tensioner with damaged bearing.
Remove the belt tensioner and turn the wheel manually. If there is noise or unusual friction, replace the component.
4.
Defective control board.
Change the position of the potentiometers C and D (page 15B) and check if the control board changes the behavior during the opening
and closing maneuvers. If it does not happen, the control board has anomalies.
5.
Motor with gearbox stucked.
Without belt and power, check if the motor rotates manually.
The door does not close.
1.
Radar sends continuous signal.
Turn off one radar at a time and check if the door closes.
2.
Photocells always open.
Make sure that the cables which connect the photocells module to the control board, close the NC circuit. Place a shunt on input 1 and
2 and check if the door closes. If it closes, check the cells power.
The door reverses when
closing.
1.
There are obstacles in the sensor detection area
.
Remove the obstacles in the sensor's detection area.
2.
The door leaves are within the detection area.
Adjust the detection area and the sensitivity of the sensor (see sensor manual).
3.
Photocells misaligned.
Align the photocells.
4.
Friction between some components of the door. Analyze, by moving the leaves manually, where there is contact between components.
The leaves hit violently
with each other.
1.
Problem in the stoppers.
Make sure that the stoppers are tight and in place.
2.
Malfunction in control board.
Change the position of the potentiometers C and D (page 15B) and check if the control board changes the behavior during the opening
and closing maneuvers.
Do a reset to the control board by switching off the batteries and the power supply for 5 seconds. Power up again in order to the door
initiate a new programming.
