Attempt circuit-breaker closing operation. Open the circuit-breaker, turn the key and remove from its seat. Racking-in operation: the circuit-breaker racks in correctly. The signal changes over. Note. Carry out some circuit-breaker closing and opening operations. The circuit-breaker opens. Model 2234 Apparatus Scale L 2778 Doc-Na 1SDH000460R0002 Page No. Both anual and electrical closing are prevented. The signals are correct. P itiv ck The spring loading lever moves correctly. The first turns the crank handle do not meet with particular resistance. Supply the shunt opening release the corresponding rated voltage. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. The signals are correct. Carry out the operating tests. ite d 1 Manual operating mechanism 2 Geared motor (if any) 3 Undervoltage release (if any) 4 Shunt opening release (if any) 5 Shunt closing release (if any) 6 Circuit-breaker lock the open position (with key padlocks) 7 Auxiliary contacts the circuit-breaker 8 Auxiliary contacts for signalling circuit- breaker connected, test isolated and disconnected 9 Lock vice circ it-b rs connected and disconnected.
