D3 safety chain control
Recoverable
When the car is moving, no signal to the board at input J7/8 (D3).
Verify:
•
Manual swing landing doors contact.
•
Manual car door contact.
•
Car load protection photocells (in safety chain).
Er - 12
D4 safety chain control (lacking)
Recoverable
When the car is moving, no signal to the board at input J7/10 (D4).
Verify:
•
Automatic car door contact.
•
Landing door lock contact (without retiring cam).
Er - 13
Rope lift with 1 or 2 speeds - Stop not on landing
Recoverable
When the floor is reached, no signal to board inputs M2A/2 (UM) and M2A/3 (DM).
Verify:
•
Brake regulation.
•
Magnetic strip position.
•
Slowdown distance.
Er - 14
D4 safety chain control (present)
Recoverable
With the car moving, no signal to board inputs J11/1 (FSC) and J11/2 (UD) simultaneously.
Verify:
•
Retiring cam excitation.
•
Landing door lock contact (with retiring cam).
•
Distance, with car moving, between retiring cam and landing door lock release lever.
Er - 15
Rope lift with variable speed drive and amendment A3 - Releveling safety circuit control
Recoverable
On arrival at the floor with doors open and UM and DM reed switches present, no signal to
board inputs RLD=J12/2 (CF4) and RLS= J12/3 (CF5).
Verify:
•
Operation of RLS and RLD reed switches.
•
Magnetic strip position.
•
Operation of the safety circuit with the Stem NC81 device or contactors K1, K2, K3.
Er - 16
Door blocked due to photocell occlusion
Recoverable
Timeout (timer = PE) due to photocell occlusion.
Verify:
•
Delay programmed in PE.
•
Photocell operation.
Er - 17
No opening of the high speed (GV) or low speed (PV) or power (P with 1 speed) contactors
Not
recoverable
Before starting, or for more than 20 seconds on arrival at the floor, the board reads 24 VDC
at input J11/1 (FSC): the high speed (GV), low speed (PV) or power (P) contactors are still
attracted.
Verify:
•
Mechanical blockage of the high speed (GV), low speed (PV) or power (P) contactors.
•
Outputs J8/6 high speed (GV) or power (P) or J8/7 low speed (PV) are still active on the
board.
