7.6 Resetting
7.6.1 Resetting an error
An error that switched the PSU01 to the locked state (fast flashing of both status LEDs) can be reset
as follows:
1. The plant is standing still.
2. Press the button at the PSU01 or request a reset at the compatible control.
3. Switch off the power supply of the PSU01 within 15 minutes.
4. Restore the power supply.
The PSU01 then performs a self test and switches back to normal mode, provided no error has been
detected.
7.6.2 Resetting all stops
All stops can be erased. The limit switch positions remain unchanged. Resetting is possible using a
compatible control, the external programming unit or a CANopen terminal. To reset all stops, please
refer to the programming manual.

In the event of a PSU01 lock, an installer must read the error type on a
CANopen monitor (see programming instructions) or a compatible con-
trol and remedy it. This may be an UCM event, but also a critical failure
of the PSU Evaluation Unit (e.g. relay failure) or of the Ants LES01. It is
the installer's responsibility to restart safely a locked plant.
All components must be in perfect operating condition. Please check
also in the Ants LES01 operating manual which and how errors are to
be remedied or processed.
If they cannot be remedied with the allowed measures described abo-
ve, the whole PSU01 must be replaced.
Perform a standard-conforming
restoration of the elevator plant and
subsequently a reset (see below).
Check the connection to the sensor
Ants LES01.

If the PSU01 cannot be reached via
CANopen, check first all network
parameters and wiring. If commu-
nication is still not possible, replace
the PSU01.
