Diagnosed cause
Testing of DW closing edge
safety device has failed.
Check closing edge safety
device.
Testing of photoelectric
sensor has failed. Check
photoelectric sensor.
Runtime limitation of door
drive, let drive cool down for
approx. 20 min.
No connection to the DES.
Check motor connection
cable and DES.
Check door mechanics /
check phases, motor
connection cable.
Voltage supply error. Check
mains connection.
Check 24 V load for short
circuit.
Mains phases have been
inverted. Correct or re-
adjust.
Door drive too fast, follow-up
of the drive too high.
Return from pulsed
operation to dead man
mode. Closing edge safety
device or photoelectric
sensor has tripped. Opening
force limitation activated,
motor duty cycle exceeded.
Opening force limitation has
tripped. Door can only be
closed in dead man mode.
Eliminate sluggishness or
blockage of the door. Check
springs. Eliminate the cause
of the excessive force, then
open and close the door.
Duty cycle exceeded. Wait
and let motor cool down.
Check contact resistances.
Check assembly of wicket

NOTICE
NOTICE
For your safety, we recommend that the door
system be checked before initial use and as
needed – at least once a year – in accordance
with the check list in the Inspection chapter. The
check can be carried out by a person with the
corresponding qualification certificate or by a
specialist company.
Service indicator
If you have selected a number of cycles in menu 9 under menu
item 90, the operating mode is automatically switched over to
dead man mode after the number of cycles selected has elapsed.
In the LED display E5E is shown.

Disposal
Dispose of packaging material in an environmentally friendly way
and in accordance with the applicable local disposal regulations.
The symbol with the crossed-out waste bin on waste elec-
trical or electronic equipment stipulates that this equipment must
not be disposed of with the household waste at the end of its life.
You will find collection points for free return of waste electrical
and electronic equipment in your vicinity. The addresses can be
obtained from your municipality or local administration. The sep-
arate collection of waste electrical and electronic equipment aims
to enable the re-use, recycling and other forms of recovery of
waste equipment as well as to prevent negative effects for the en-
vironment and human health caused by the disposal of hazard-
ous substances potentially contained in the equipment.
