Reset failure (CRS/CRD open)
Not
recoverable
During reset, when the up or down signal is sent, the board does not have 24 VDC at J11/1
(FSC) after two/four attempts, or does not receive 24 VDC at J11/2 (UD).
Verify:
•
CRS/CRD or CRSB/CRDB phase plugs.
•
The up/down board control signals at outputs J8/2(S) and J8/3(D).
•
The reciprocal contacts S/21-22 and D/21-22 in series with the up (S) and down (D)
contactors.
•
The up (S) and down (D) contactor coils.
•
With amendment A3:
▪ No closure of the main brake (gearless) or auxiliary brake (geared) de-excitation
control contacts.
▪ No excitation of the brake contact control contactors, or their contacts are defective.
▪ No closure of the de-excitation control contact of the speed governor coil (Montanari).

Safety circuit malfunction (it did not open when the floor was left)
Not
recoverable
In hydraulic systems, the board controls the status of the safety circuit via a 24 VDC signal at
J11/5 (CCS): the "active" safety circuit signal must terminate when the car is away from the
floor.
The control is run when the car transits the slowdown strip at the destination floor: if in error,
the car is moved to the lowest floor and remains out of service.
Verify:
•
If 24 VDC is present at input J11/5(CCS) with the car away from the floor, verify:
▪ Operation of the reed switches and relay RZA/RZB.
▪ With contactors K1, K2, K3: contactors K1, K2, K3.
▪ With the Stem NC81 device.

UM reed switch count error (does not close or has missed more than 3 pulses)
Not
recoverable
The board monitors the operation of the UM (M2A/2) and DM (M2A/3) reed switches: 24 VDC
present when the reed switch is closed.
Verify:
•
Operation of the UM reed switch.
•
Presence and positioning of the magnetic strips.
•
Condition of the flexible cables.
•
Presence of 24 VDC at the common contact of the UM/DM reed switches.
Er - 29
DM reed switch count error (does not close or has missed more than 3 pulses)
Not
recoverable
The board monitors the operation of the UM (M2A/2) and DM (M2A/3) reed switches (24 VDC
present when the reed switch is closed).
Verify:
•
Operation of the DM reed switch.
•
Presence and positioning of the magnetic strips.
•
Condition of the flexible cables.
•
Presence of 24 VDC at the common contact of the UM/DM reed switches.

Amendment A3 hydraulic – Operation test of the separate opening of the 1st valve failed
Not
recoverable
During testing at the lowest floor with the doors closed, the system releveled when the 1st
valve opened.
Verify:
•
Operation of the 2nd valve.
