4.5 Module Door Motor Reset Failure
Fault Description:
The module door is at the abnormal position and cannot run to the designated position.
Troubleshooting:
1. When the instrument is powered off, slowly pull the module door with hand and repeat this action for
5-10 cycles. Restart the instrument to check whether the fault exists.
2. Check whether the module door motor shading plate and module door photoelectric switch can sense
each other.
3. Insert and extract the power cord of module door motor and photoelectric switch wire of module door
motor again, restart the instrument (the cabin door is closed before the instrument is restarted) to check
whether the module door motor runs (whether the module door moves up and down normally) and
check whether 2 red indicators of magnetic photoelectric switch wire are normally on and whether the
fault exists.
4. If all items above are normal, replace the main control panel. Before replacing the main control panel,
you need to enter the commissioning mode to record all motor parameters. After replacement, enter all
parameters manually.
Maintenance Methods:
1. If the sliding between the module door and the linear slide ways on its both sides is not smooth, slightly
loosen the fixed screws between the door panel connecting plate and the slide way sliding block on both
sides of the module door, move the position of the door panel connecting plate back and forth, and pull
the module door up and down. Tighten the screws when the module door slides smoothly, as shown in
the figure below.
