Error Acknowledgement - Motus 36112 Betriebsanleitung

Diagnostic function
Via various diagnostic functions, the hybrid motor
starter is able to identify and signal a range of errors,
such as overcurrent, asymmetry, phase failure or self-
test errors.
A self-test is carried out before each power-on
process. If a problem is detected, the device does not
power on and instead displays the message "Error
during self-test". Errors can be caused by defects in

— the device must be replaced
Internal error in Bimetal function: The motor current is higher than
controller or I/O the nominal motor current specification (e.g. class
devices (maintenance 10A): Cooling time running! (20 minutes)
requirement, NE44) Countdown of cooling period (20min) only starts
After 2 minutes, the „L" or „R" flashes:
A manual reset is possible.
Error restoring the system state:
Checksum erroneous. The thermal memory of the
bimetal function is set to the max. value. The error
must be manually acknowledged, also in automatic
mode.
Symmetry: The motor currents deviate from each
other by more than 33%.
Phase failure: Phase failure with pending
control voltage
Possible causes: minimum current not achieved,
below 0.06A (0.6A), 0.15A (2.4A), 1.2A (9A)
fault in mains voltage, fuses have been triggered,
motor line interrupted
Blocking: The max. measurable motor current is
exceeded for more than 2s.
Explanation: A = LED switched off / E = LED permanently lit / B = LED fl ashes at a frequency of 2Hz (50:50)

Error acknowledgement

Three different options are available for error acknowl-
edgement.
Manual (set / reset button)
Press the set / reset button on the front of the device.
Revision 6, status 05.2017
the power electronics or insulation faults in periph-
eral equipment. An "Error during self-test" cannot be
acknowledged and is stored internally in the device.
In case of repetition of the "Error during self-test",
the device cannot be put into operation again — it
must be replaced (safety precaution).
If an error is detected, the device immediately
switches to a safe, shutdown state.
To exit the safe, shutdown state, the corresponding
error acknowledgement is required.

If the set / reset button is still being pressed after approx.
2s, the hybrid motor starter adopts an error state again. If
the acknowledgement request (actuated set/reset but-
ton) is active for more than 6s, an advanced test is con-
ducted for the power output module and then a switch
performed to the „Parameterization" operating mode.
