Description/cause
The internal 24 V DC power supply of the
controls used to provide the electronics com-
ponents (sub-assemblies within the AC 01.2
controls and in the actuator) has exceeded
the power supply limits .
Internal warning: Replacement parameters
are used as no valid parameters are available
(Remedy: Reboot controls/actuator)
Actuator position feedback has not yet been
referenced to the end positions.
The current signal range of the position feed-
back is outside the permissible range.
Loss of signal of the actuator position feed-
back signal
Wrn event mark (internal system warning)
Wrn Tm mark (internal system warning)
Pressure of hydraulic accumulator lower than
the minimum value of the set accumulator
pressure.
Permissible number of starts of the hydraulic
pump has been exceeded.
Configuration of the accumulator pressure is
incorrect.
Available version of 'I/O interface' electronics
sub-assembly does not correspond to the tar-
get configuration.
Configuration for function of Remote interface
is incorrect.
Configuration of Remote interface function is
faulty.
Corrective action
Remedy
Check internal 24 V DC voltage supply.
Reboot AUMATIC.
Operate actuator fully in end positions OPEN
and CLOSED.
Verify primary reduction gearing settings
within the actuator.
Check position feedback.
Check system configuration.
Check system configuration.
Check hydraulic system
Check hydraulic system.
Check hydraulic system.
Check parameter I/O interface M0139.The
setting must correspond to the wiring dia-
gram.
Check wiring.
Check I/O interface.
Check configuration.
