ES 200 Easy/ES 2QO-2D/ES 200 C048/DAC 300
The 27 V power supply for radar motion detectors, the locking device etc. is short circuit proof. In the event of
a short circuil, both control LED lights of the light barriers go out and the 7-segment display indicates error 3
(program switch) Once the short circuit is removed, the 27 V power supply is restored automatically.

The motor amplifier is additionally short circuit proof. Once the short circuit is removed, the motor is supplied
with power.
If, during commissioning or operation, faults arise, check the following points:
• Have all maintenance intervals been observed/has the maintenance been performed?
• Have all wear parts been checked and replaced if required?
• Is the power supply connected?
• Is the EMERGENCY OFF pushbutton off, i.e. unlatched?
• Is the program switch set correctly?
• Are the areas monitored by the light barriers clear and clean?
• Is the door blocked by an obstruction?
• Is the door running smoothly (counter rollers, floor guides)?
• Are all external activators, EMERGENCY OFF pushbutton, program switch and locking device
connected correctly?
• All connection points checked?
• Is the rechargeable battery pack correctly connected?
For further assistance, consult the following troubleshooting table.
Should you perform installation work, disconnect the power plug and the battery pack in order to keep
the control unit voltage.free. After a fault is redeemed, the error code must be deleted.
Deleting of error codes: • Set program switch to OFF.
