7.7Voltage Sensing Board (VSB)

Line voltage sensing The supply voltage is sensed using the analog board VSB (Voltage Sensing Board) via the two analog inputs on control board CUSA. Furthermore, the 24 V power supply is monitored on this board and a relay provided to control the main contactor.

The VSB is an integral component of the AFE basic mains module.

NOTE

Connect the 24 V power supply to -X3 terminals 2 and 3.

 

 

The remaining signals are carried via the supplied cable harness.
