Page 16: Operation
CONTROL CIRCUITS The HCV-7HA is a Magnetically Held type of contactor. Contactor closing is controlled by the drive unit. The drive unit is a control board that applies a relatively high voltage to the closing coils for a short period of time to close the contactor and then reduces the voltage to the coils for holding the contactor closed. - Page 17 OPERATION Page 13 LEGEND CC ---- Closing Coil 1 & 2 ---- Control Power Input Terminals 3 & 4 ---- Control Switch Input Terminals 5 & 6 ---- Closing Coil Terminals 7 & 8 ---- No Connection Figure 5 - Internal Connection of the Magnetically Held Type LEGEND CC ---- Closing Coil 1 &...

Page 25: Vacuum Check
The contactor should be disconnected from the TEST EQUIPMENT: main circuit and be in the OFF position. Toshiba offers a compact vacuum checker (Type Connect all the line side primary terminals CI35-1D, Figure 10) which enables a quick and easy together and to the output of the vacuum checker check on vacuum interrupter internal pressure. - Page 26 Page 22 MAINTENANCE CRITERIA: If a current flow above 5 milliamperes is observed or if breakdown occurs, one or more of the 1 minute interrupters has insufficient vacuum and must be 10kV AC replaced. (14kV DC) Exception: If the current exceeds 5 milliamperes the first time the voltage is brought up, reduce the voltage to zero and increase it again.
