(4) Communication line ground
(5) Encoder line ground
Please exclude all items above if short circuited.
2. Grounding check: (Make sure the following items are reliably grounded)
(1) Control cabinet ground
(2) Motor ground
(3) Lift car ground
(4) Door motor ground
(5) wire casing ground
(6) Encoder shield control cabinet ground
(7) Encoder shield motor terminal ground
Note: single terminal grounded for asynchronous motor encoder shield, both terminals
grounded for synchronous motor Encoder shield.
3. Check communication lines, encoder cable and power line wiring: (Please confirm whether the
site meets the following requirements, if not, please correct):
(1) Well communication line is twisted pair line and the twist distance <35cm
(2) Lift car communication line is twisted pair and the twist distance <35cm
(3) Group control communication line of parallel connection is a twisted pair line and the
twist distance<35cm (only parallel connection or group control elevator)
(4) Encoder lines and power lines go separate trunking
(5) Communication lines and power lines go separate trunking
(6) Group control communication lines of parallel connection and power lines go separate
trucking (only parallel connection or group control elevator)
8.3.2 Checks after Power on
1. Close the main power switch. If the green light on the phase sequence relay KAP is
on, the phase position is correct. If the green light is not on, shut off the main power
supply; swap any two-phase positions and then power on again.
2. Check all terminal voltage of the isolation transformer TCO in the control cabinet,
and see whether they are within the nominal range.
3. In the premise of carrying out the above steps correctly, proceed with the following
steps:
(1) Close the fuse
FUn
(n = 1, 2, 3 ... ...);
(2) Close the door open/close power control switch; open/close TPB is powered on,
and the motherboard is electrified to run.
Each terminal voltage of switching power supply is as follows:
Table 8.1 Terminal voltage of switching power supply
Terminal
L～ N 24V～ COM
voltage 220±7%VAC 24.0±0.3VDC
(3) Reset the emergency stop switch of the control cabinet, connect safety loop, and the LED
lights corresponding to the motherboard input point are on.
(4) Check the following circuit:
