Elevator debugging process(e)

1.2 Check before commissioning slow
External inspection is completed, removing the brake control line, close the power to observe the elevator in the non-operating state brake control terminals no output even if the brake control cable connected, the brake will not turn on, and then connect the power brake control line. Ready to run slow.
1.2.1 checks after power
1) Check the controller board into the power system voltage between the terminals, requiring DC24V0.5V inside.
2) Check the system inside and outside the church the power supply voltage to DC24V0.5V inside.
1.3 overhaul test run
1) Input signal inspection: careful observation of the elevator during operation of the switching signal received is normal operation sequence.
2) output signal inspection: the motherboard carefully observed each output point is correct, and is working properly, the control signal, the contactor is normal.
3) Check the running direction: the elevator placed in non-end station, electric slow run, observe the direction of running direction is consistent with the purpose, if any exchange of different motor-side power in two phases.
4) If the elevator test tool speed abnormal operation occurs jitter, through the operation panel observed current is too large, the motor is running abnormal sound, check the encoder wiring, switches A, B phase.
1.4 Express check before running
Express check before tuning down forced deceleration switch, limit switch, limit switch is functioning normally, leveling flapper installed correctly, leveling sensor action sequence is normal. Encoder wiring is correct, the number of pulses per revolution encoder settings are correct.
1.4.1 Express check before
1) Express debugging and slow when debugging a certain time interval, before climbing again perform debugging checks.
2) inside and outside the church the power supply voltage to DC24V0.5V inside.
3) Confirm the safe and reliable switching action.
4) Confirm safe touch panel circuit wiring is correct.
5) intercom wiring is correct, call normal.
6) station clock wired correctly.
7) car lighting, fan wiring is correct.
