Diagnostic Function - Wöhner MOTUS ContactronControl Notice D'utilisation

• After the control supply voltage is applied, all LEDs
light up once, as an LED test.

Diagnostic function

Through various diagnostic functions, the hybrid motor
starter can detect many internal errors and also exter-
nal errors (I/o errors).
• If an error is detected, the device is switched to the
safe shutdown state.
Status LED description
oFF No supply voltage (control supply voltage) present
operational readiness Supply voltage (control supply voltage) present
Drive switched on • Reverse running (L)
• Forward running (R)
Internal error Internal device error –
Device replacement required
Internal error in Bimetal function: The motor current is higher than the
controller or I/o nominal motor current specification (e.g. class 10A):
devices (maintenance Cooling time running! (20 minutes)
requirement, NE44)
• Error in reverse running.
• Error in forward running.
After 2 minutes, the „L" or „R" flashes:
A manual reset is possible.
• Error in reverse running.
• Error in forward running.
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.
External error in Symmetry: The two motor currents deviate from each
controller or I/o other by more than 33%.
devices (maintenance
Phase failure: Phase failure with pending control voltage
requirement, NE44)
• Error in reverse running (left rotation).
• Error in forward running (right rotation).
Possible cause: Fault in mains voltage, fuses have been
triggered, motor line interrupted
Blocking: The max. measurable motor current is exceeded
for more than 2s.
• Error in reverse running.
• Error in forward running.
Explanation: A = LED switched off / E = LED permanently lit / B = LED flashes 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 1, Stand 05.2012
• All internal errors cannot be confirmed and are
stored in the device. Afterwards the device cannot
be started up.
• In case of external errors, an error acknowledgment
is required to exit the safe shutdown state.

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.
