  After JN15-12/D31.5 Motorized earthing switch is installed, according to the following steps for debugging:

  1. Read the specification of REC-10-HB switchgear electric control device.
  According to the wiring terminal diagram of REC-10-HB switchgear electric control device sample, connect electric earthing switch wiring terminal in accordance with the electrical diagram terminal number.

  2. Motor earthing switch terminal is pluggable terminal block. When complete connection,before testing power-on, user should pull out terminal, hang measured terminal 1.2 foot motor power During press the switch knob of electric control device,need insure 1 foot is positive power(VDD), ) foot is negative power(GnD ). If wiring is correct, then plug termina

  3. By test, observing whether the indicator light function of ERC-10-HB switchgear electric control device is correct. If not correct, please check the correctness of terminal and in place of signal source of switch opening, closing is correct or not.

  4. Manual operate earthing switch opening-closing, observing whether the display of electric control device is correct. If correct, can debug by motor operation.

  5. Special note of motor operation test: switchgear electric control device send intruction of earthing switch opening or closing. If the operating conditions are met, then will perform earthing switch opening or closing operation, observing whether the mechanism rotation direction is correct. If mechanism rotation direction is opposite, user should immediately turn off the power or press the scram button on device to stop the current operation, try again after changing moter positive and negative terminals. If the operating conditions are not met,(such as the interlocking signal of control device 11 foot is not correct), control device will not work properly, the user should settle accordingly to meet the operating conditions and try again.

  6. The switch off motion and the signal of the opening and closing reaching of the electric earthing switch are subject to the connect between operating shaft cam arrangement and microswitch. When electric earthing switch is connected with cabinet interlock, we should offer electric control device power supply, Combining with the control device opening and closing indicator light, manually adjust the opening and closing reaching of earthing switch(note:Wher the spring of earthing switch is just over dead point,the operating handle should seize up immediately), observe whether the control device opening and closing indicator light can synchronously indicate or not. Otherwise, we should adjust the upper and lower position of twin thread screw in the interlock to make them synchronously. If interlock position error is too big to reach synchronic we should make a fine adjustment in position between micro-switch and cam, and then observe control device just to make the corresponding indicator light.

  WIRING INSTRUCTIONS OF MOTORIZED EARTHING SWITCH

  1. When switch equipment motorized control device terminal No. 3 and No. 4 corresponds to terminal No. i positive and No. 2 cathode, be careful not to reverse the polarity of the power supply to avoid damage to the motor. Through the debugging to observe whether the rotates direction of earthing switch operating shaft gear met the switch’s opening, closing state, otherwise swap the positive and negative

  2.If operate motorized earthing switch separately(not loading), switch equipment motorized control device terminal No. 11 and No. 10 (0V common terminal) short.
