Additional Information
The S1SW P monitors the rundown on a three-phase asynchronous machine with standstill detection. The regenerated voltage induced from the motor is measured; standstill is signalled (relay contact) if the value falls below a set threshold. A second relay signals a fault if the voltage does not fall below the set threshold within the set rundown monitoring time. The time measurement is started by closing voltfree start contact (N/C contact on the motor contactor at Y3, Y4). The slide switches can be used to switch the measuring ranges.
