Meaning/cause Troubleshooting
In 73 None
Braking circuit test
The periodically performed test (every 24 hours)
of the internal braking circuit could not be
successfully performed.
System tolerances and environmentally conditions
influence the braking circuit test. Therefore the test
cannot always be successfully completed the first
time. The information is shown in this case. This, for
example, is the case if the door is manually passed
through during the measurement. If the test has been
negative 10 x in a row, the error message E 73 will be
displayed.
In 91 None
DCW communication
At least 1 registered DCW device is missing.
Reconnect the corresponding DCW device.
If this is not possible, you must restart the drive unit.
Press simultanuously the pushbuttons and on
the internal user field for a minimum of 3 seconds.
E 02 2 x
flashing
Locking error
The drive unit tries to open or close a locking device
with a feedback contact or a DCW locking device.
An error occured.
In this case, you have to assume a defect on the
locking device or an error in the wiring. The locking
feedback contact must be tested and replaced, if
necessary.
E 03 3 x
flashing
DCW program switch is missing Check and replace, if necessary, the DCW program
switch.
E 04 4 x
flashing
Test error safety sensor
The test of the corresponding safety sensors
has not been successful. A test signal is sent to
the corresponding sensor prior to each opening
or closing movement. The drive unit expects a
response within a certain time window.
First, it must be checked whether the parameter "Test
safety sensor" is configured accordingly. Then it is to
be checked whether the test has also been activated
on the sensor itself and whether it is operated with the
same level. The test is turned off when the sensors are
delivered.
E 12 12 x
flashing
EEPROM error
The internal memory check could not be
successfuly completed. The drive unit operates in
the closer mode.
You can try a reinitialization by reloading the current
firmware. If that fails, the control unit must be
replaced.
E 13 13 x
flashing
Excess current detection
More power is taken from the system than the
mains adaptor can provide.
The motor consumes too much power or the control
end stage is defective. In case of recurrence, the
components motor gear unit and/or control unit are to
be replaced.
E 15 15 x
flashing
Faulty teach-in run
The teach-in run could not be completed.
The error can occur if the teach-in run has been
interrupted, e.g. through manipulation of the door
during the process. The teach-in run must be
restarted.
E 25 5 x
flashing
SVP DCW PR module
The test was negative.
Check the wiring and, if necessary, replace the PR
module.
E 51
E 52
E 53
5 x
flashing
Incremental encoder error
The incremental encoder monitoring has detected a
faulty state.
In case of an error, the plug connections of the
incremental encoder and the motor as well as the
circuit of the locking device are first to be checked
for a short circuit. If no error can be found, the motor
gear unit must be replaced. The error can be caused
by a defective motor or a short circuit in the electric
circuit of the locking device. The motor gear unit must
be replaced in case of a defective motor.
E 62 6 x
flashing
The second system has an incompatible firmware
version for the 2-panel operation.
Both control units are to be fitted with the same
firmware version.
E 63 6 x
flashing
The second system has an incompatible fire
protection setting.
In case of 2-panel systems, the Upgrade Card Fire
Protection must be installed in both control units.
E 71 7 x
flashing
System error 1 (2nd switch-off path)
In order to switch off the drive unit always reliably,
several switching elements are used. They are
periodically tested for its functioning.
If the test is always negative, the control unit must be
replaced.
E 72 7 x
flashing
System error 2 (current measurement circuit)
The current measurement circuit is part of the
safety mechanisms and will be periodically tested
for its functioning. The drive unit operates in the
emergency mode.
If the test is always negative, the control unit must be
replaced.
