INSTALLATION MANUAL
Er - 02
Thermal protection (TP) tripped
Recoverable
It is signalled when on board terminal M2A/1, a resistance value greater than 2000 ohm as to
GND is detected.
Hydraulic: the car it goes to the lowest floor.
Rope lift: the car stops at the nearest floor.
4 min. after temperature reset, the lift returns into service. Showing on the display a countdown
(every 3 seconds) from 80 to 0.
Verify:
•
Connection to GND and thermistor resistance value and any other contact wired in series
on the same circuit.
•
Direct wiring to GND (without thermistors).
•
Controller ground connection of main line.
Er - 03
No closure of high speed (GV), low speed (PV) (or power (P) for 1 speed systems) contactors
or retiring cam (RP)
Recoverable
At start up the board does not measure 24 VDC on input J11/1 (FSC) to confirm excitation of
the high speed (GV) or low speed (PV) contactors or the power contactor (P).
Verify:
•
Excitation of the high speed (GV) or low speed (PV) or power (P with 1 speed) contactors
•
Excitation, if installed, of the RP contactor and retiring cam.
•
Voltage at the end of safety chain, after the landing door lock contacts (when activated by
the retiring cam).
•
Input voltage at board terminals J8/8 low speed (PV), J8/5 high speed (GV) or power (P).
•
Output voltage, with controls activated, at board terminals J8/7 low speed (PV), J8/6 high
speed (GV) or power (P).
•
With the high speed (GV) or low speed (PV) or power (P) contactors excited, their auxiliary
contacts wired between the +24 terminal and the board's J11 (FSC) connector input.
Er - 04
No closure of the up (S) or down (D) contactors
Recoverable
At start up the board does not measure 24 VDC on input J11/2 (UD) to confirm excitation of
the up (S) or down (D) contactors.
Verify:
•
Excitation of the up (S) or down (D) contactors.
•
Voltage at terminals CRS/CRD or CRSB/CRDB (top and bottom floor phase plug contactors).
•
Input voltage at board terminals J8/1 (S), J8/4 (D).
•
Input voltage, with the controls activated, at board terminals J8/2 (S) and J8/3 (D).
•
Contacts S/21-22 and D/21-22 of the up (S) and down (D) contactors.
•
With the up (S) or down (D) contactor excited, the corresponding auxiliary contacts
connected b24 and board input J11/2 (UD).
•
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
or similar).
