Er - 05
Rope lift with variable speed drive: No closure of the power contactors (TL1 and TL2)
Recoverable
At start up the board does not measure 24 VDC on input J11/5 (CCS) to confirm excitation of
the power contactors (TL1 and TL2).
Verify:
•
Excitation of the power contactors (TL1 and TL2)
•
Voltage at the up (S) and down (D) contactor contacts which control the power contactors
(TL1 and TL2).
•
Variable speed drive fault signal contact (error condition reported on the variable speed
drive keypad).
•
With the power (TL1 or TL2) contactors excited, the corresponding auxiliary contacts
connected b24 and board input J11/5 (CCS).
Er - 06
No door closure
Recoverable
Case 1: once door closure has timed out (t5 = 15 seconds), the board does not receive the door
contacts closed signal at terminal J7/10 (D4).
Led D4 on REMP2 does not light up.
Verify:
•
Car door or door lock contacts (if no retiring cam is present).
•
The front door closure contactor (CP…) or rear door closure contactor (CP1..) is not excited.
•
Door closure limit switch is open.
•
NC contact of the electrical reciprocal of the front door open contact (AP..) or rear door
open contact (AP1..).
•
No control signal output from the board at terminal J6/10 (CP).
•
No power to the car door motor (if three-phase).
•
No power to the car door regulator board (single-phase 220 VAC).
•
No closure signal to the car door regulator board (single-phase 220 VAC).
•
Delay t5 timeout (15 seconds).
Recoverable
Case 2
: after the door closure delay has timed out (t5 = 15 seconds), input J11/3 (DRA) or
J11/4 (DRB) still carries the 24 VDC voltage from the front door CP.. or rear door CP1.. closure
contactor.
Verify:
•
No opening of the closure limit switch.
•
With the operator powered in run, disconnect the front door (CP..) or rear (CP1..) closure
contact from input J11/3 (DRA) or J11/4 (DRB).
