TSBSC - OPERATING MODE

Overload operation mode Overload operating mode

The Shock Relay does not respond to motor starting current within the preset start time period. The Shock Relay does not respond to motor starting current within the preset start time period. Overload operating mode

The Shock Relay does not respond to excess current (spike) if it does not exceed the preset shock time. The Shock Relay does not respond to excess current (spike) if it does not exceed the preset shock time.

The Shock Relay responds when excess current exceeds the preset shock time. The Shock Relay responds when excess current exceeds the preset shock time.

Motor stops

Once the motor current falls below the preset level, underload is detected and a signal is sent to stop the motor. For under-load detection, the output contact is set to alarm output.* * However, in case of the underload detection, the output contact becomes choice of either alarm output or no action.

The Shock Relay does not respond to short- term current degradation if it does not exceed the preset shock time. The Shock Relay does not respond to short- term current degradation if it does not exceed the preset shock time.

The Shock Relay responds when current degradation continues for longer than the preset shock time. The Shock Relay responds when current degradation continues for longer than the preset shock time.
