The 24V DC control supply voltage and control voltage
inputs must be operated with power supply modules
according to DIN 19240 (max. 5% residual ripple)!
In order to avoid inductive or capacitive coupling of
noise emissions where long control wires are used, we
recommend the use of shielded wires.

Vi uali ation – Statu -LED
The hybrid motor starter visualises the operating sta-
tuses with a total of four LEDs. The functions of the
LEDs follow the NE 44 NAMUR recommendation.
• A green LED (PWR) indicates the general device
status.
• Left or right rotation of the drive (reverse or forward
running) is indicated by a yellow LED (L or R respec-
tively).
• An internal or external error (process error: overcur-
rent, asymmetry, phase failure) is indicated by a red
LED (ERR).
• After the control supply voltage is applied, all LEDs
light up once, as an LED test.
Diagno tic function
Through various diagnostic functions, the hybrid motor
starter can detect many internal errors and also exter-
nal errors (I/O errors).
Statu LED e cription
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 require
Internal error in Bimetal function: The motor current is higher than
controller or I/O the nominal motor current specifi cation (e.g. class
devices (maintenance 10A): Cooling time running! (20 minutes)
requirement, NE44) Countdown of cooling period (20min) only starts
• Error in reverse running.
• Error in forward running.
After 2 minutes, the „L" or „R" fl ashes:
A manual reset is possible.
• Error in reverse running.
• Error in forward running.
Error re toring the y tem tate:
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 two motor currents deviate from
each other by more than 33%.
Pha e failure: Phase failure with pending
control voltage
• Error in reverse running (left rotation).
• Error in forward running (right rotation).
Po ible cau e : minimum current not achieved,
below 0.06A (0.6A), 0.18A (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.
• Error in reverse running.
• Error in forward running.
Explanation: A = LED witche off / E = LED permanently lit / B = LED fl a he at a frequency of 2Hz (50:50)
Error acknowle gement
Three iff erent option are available for error acknowl-
e gement.
Manual ( et / re et button)
Press the set / reset button on the front of the device.

• If an error is detected, the device is switched to the
safe shutdown state.
• All internal errors cannot be confi rmed 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.
