Table 3.T Warm Start Setting Parameters

Emergency Override of Thermal Trip (Emergency Start)

Suggested Procedure

Procedure when PT100 and PTC are not used:

1. Momentarily bridge terminals Y11-Y12 (voltage-free contact). A spring return key

switch is recommended.

2. LCD flashes “EMERGENCY START”.

3. If the thermal release has tripped, it can now be reset.

4. If the maximum number of starts per hour has been reached, the counter has one

start deducted.

5. Start the motor.

6. As soon as the motor starts, the stator winding memory will be set to zero (copper

losses only).
