Elevator debugging process(a)

Elevator commissioning specific content
1. Elevator commissioning phase, make sure the hoistway, the car unattended circumstances! Otherwise, a major accident could happen!
To facilitate debugging debugging members are listed below in the order when debugging elevator, in the peripheral circuit, mechanical installation fully in place in the case before debugging.
1.1 idle before commissioning checks.
Elevator entered the commissioning phase, the correct debug the elevator tool normal safe operation of protection. When debugging should be at least two simultaneously. If abnormal situation should be immediately cut off the power.
1.1.1 Field mechanical, electrical wiring checks.
Before powering on the system you want to check the external wiring to ensure personal safety and the components.
1) Check the part number matches.
2) safety circuit conduction.
3) Lock Loop conduction and are reliable.
4) wells flow, no car, and have suitable conditions for operation of the elevator.
5) grounded.
6) according to the manufacturer drawings correct external wiring.
7) Each switch is working properly, reliable action.
8) Check the resistance of the main circuit and white, check whether there is a short circuit to ground.
9) confirm the elevator is in maintenance state.
10) mechanical parts in place, will not cause equipment damage or personal safety.
