EARTHQUAKE COUNTERWEIGHT TEST
This test is designed to test the operation of earthquake and counterweight
logic
1. Make sure the counterweight mid-point parameter is set. Go to MAIN MENU
| SETUP | FIRE/EARTHQUAKE | COUNTERWEIGHT MID PT and input the
midpoint distance of the hoistway. The midpoint distance can be determined
by moving the car in the hoistway level with the counterweight and recording
the step position from the SRU screen, located above the “CMD:” value in
the lower left corner.
2. Momentarily jump either of the EQ (+/-) terminals on the Machine Room DIN
rail to the Earth Ground terminal on the DIN rail.
3. The Car should stop and correct away from the counterweight to the nearest
landing. There it will open the doors, fault out, and go out of service.
4. To reset: Make sure the counterweight input is high (LED is on) and then
press the reset button. This will reset the Earthquake logic.
