Flashing
13 x
Overcurrent detection
• Motor is consuming more
current than drive unit can
provide.
1. Motor is consuming too much power, check for any external
causes.
2. Drive unit or control unit is defective.
3. If error repeats, operator must be replaced.

Flashing
15 x
Faulty learning cycle
Learning cycle could not be
completed (Chapter 19).
1. Error may occur if learning cycle has been interrupted, for
example if door movement has been interrupted during the
learning cycle.
2. Learning cycle must be repeated.

SVP-PR 12 power reserve module
test negative
1. See Appendix A, parameter
TS
, Power reserve module test.
2. Check power reserve module and its wiring.

Incremental encoder error
• Motor gear unit encoder
monitoring detected a faulty
state.
1. Check encoder plug connection at operator.
• Secure connection.
• Wiring terminations
• Short circuits.
2. Check locking device for short circuits.
3. Error can be caused by defective motor or short circuit in locking
device.
4. Motor gear unit must be replaced in event of defective motor.

Incompatible firmware version,
double door system, second system.
1. Equip both operators with same firmware version.

Incompatible fire protection setting
,
double door system.
1. For double door systems, the Upgrade card fire protection must
be installed in both control units.

System error 1, 2nd shutdown option
1. In order to reliably switch off the drive unit, several switching
elements are used and their functions are tested periodically.
2. If the function test always results in the error code, the control
unit must be replaced.

E 72
Flashing
7 x
System error 2, current measurement
circuit
1. The current measurement circuit is part of the safety
mechanisms and its function is tested periodically.
2. If the function test always results in the error code, the control
unit must be replaced.

System error 2, current measurement
circuit
1. The braking circuit is a safety element in the closer mode and will
be tested every 24 hours.
• During the test the motor is shut down during door closing and
the door closes at a set angle in emergency mode.
• Test can be noticed as a short jerk on the door and is normal.
2. Error can be due to door closing in the deenergized state too fast
(under 3 seconds). See Chapter 17, Power fail closing speed.
3. Check the closing speed and reduce if necessary.
14
Energy management
• Motor is too hot (for example, too
high an ambient temperature)
• System responds automatically.
1. Movement dynamics in the closed direction will be reduced.
2 Movement dynamics in both the open and closed directions will
be reduced.
3 System shuts down for 3 minutes (door closer mode).
4 Hold-open time will be extended.
