None Braking circuit test
System could not successfully perform
cyclical test (performed every 24 hours) of
internal braking circuit.
■ Braking circuit test is influenced by system
tolerances and by environmental conditions; for these
reasons the cyclical test cannot always be successfully
completed the first time. An information message (ln 73)
is then displayed.
■ Cyclical test may fail, for example, if someone uses door
while cyclical test is in progress.
■ If cyclical test fails ten times in a row, error message
E 73 is displayed.
In 91
None DCW® communication
At least one registered DCW® device is
missing.
■ Reconnect corresponding DCW® device.
■ If this is not possible, a restart of operator must be
performed:
Press and hold and on user interface for >3 seconds.
E 02
Flashing
two
times
Locking device error
Operator is attempting to open or close a
locking device with feedback, or a DCW®
locking device.
An error has occurred during this process.
■ It is probable that locking device is defective, or there is
an error in wiring.
■ Locking device feedback system must be checked and
replaced if necessary.
E 03
Flashing
three
times
DCW program switch missing
■ Check and replace, if necessary, the DCW program switch.
E 04
Flashing
four
times
Safety sensor test error
Test of moving safety sensors was
unsuccessful:
A test signal is sent to the corresponding
sensors before each door opening or closing
cycle, operator then waits for a response for
a certain period of time.
■ Check whether “safety sensor test” parameter ST has been
configured according to the respective sensor equipment.
■ Check whether test signal is also activated on sensors
themselves and is being operated at same level.
■ Test is switched off when sensors respond.
E 12
Flashing
12 times
EEPROM error
Internal memory check was not completed
successfully.
Operator is working in door closer mode.
■ Upload current firmware in order to reinitialize system.
■ If this fails, the control unit must be replaced.
E 13
Flashing
13 times
Overcurrent recognition
Greater motor current is being supplied
than control unit's power supply unit is
designed to provide.
■ The motor is consuming too much current or control unit’s
power amplifier is defective.
■ If this error message appears repeatedly, the motor gear
unit or control unit components must be replaced.
E 15
Flashing
15 times
Faulty learning cycle
Learning cycle could not be completed.
■ Error may occur if learning cycle has been interrupted, for
example if door movement has been interrupted during the
process.
■ Learning cycle must be restarted.
E 25
Flashing
five
times
SVP DCW PR module
(power reserve module)
The test was negative.
■ Check wiring and replace the PR module if necessary.
E 51
E 52
E 53
Flashing
five
times
Incremental encoder error
Motor gear unit incremental encoder’s
monitoring feature has detected a faulty
status.
■ Check incremental encoder and motor plug connections for
short circuits.
■ Check locking device’s electric circuit for short circuits.
■ Error may be due to a defective motor encoder.
If motor encoder is defective, motor gear unit must be
replaced.
■ If no error can be found, motor gear unit must be replaced.
E 62
Flashing
six times
Firmware version incompatibility– second
system
Second system has a firmware version that
is incompatible with double-door operation.
Equip both control units with same firmware version.
E 63
Flashing
six times
Fire protection setting incompatibility –
second system
Second system has an incompatible fire
protection setting.
If using double-door systems, Fire Protection upgrade card
must be installed on both control units.
