TABLE 0.2 MC-MP-1ES Status and Error Messages
= LED off = LED blinking
LEDs MEANING PROBABLE CAUSE NEEDED RESPONSE
(01)
Earthquake Normal
Operation
The car is allowed to run at reduced
speed on Earthquake Normal
Operation. (EQI is high, CWI is
low; used for ANSI earthquake
operation only.)
The elevator may be returned to normal service by means of momentary
reset button on the earthquake board (HC-EQ2). This should be done by
authorized personnel, after it has been determined that it is safe to do so.
Should the system remain in this mode of operation after the reset button
has been pressed, check the status of the EQI input.
(02)
Earthquake Power
Up Operation
The CWI and/or EQI input was
detected high at power up. (Used
for ANSI Earthquake Operation
only.)
The elevator may be returned to normal service by means of momentary
reset button on the earthquake board (HC-EQ2). This should be done by
authorized personnel, after it has been determined that it is safe to do so.
Should the system remain in this mode of operation after the reset button
has been pressed, check the status of the EQI and CWI inputs.
(03)
The car is on
Attendant operation
The attendant service input (ATS)
is activated.
Attendant service is maintained as long as the ATS input is activated, in the
absence of any “emergency services” (e.g., fire service). Check the status
of the ATS input, and determine if the status of the input is appropriate.
(07)
The Hall Call Bus is
disconnected
A problem in the wiring or fuses.
There is no power to the Hall Call
circuits on the HC-CIO board.
Check the Hall Call Bus fuse. Check the wires that go to the Hall Call
Power inputs on the HC-CIO board in the controller.
(OF)
The Car Call Bus is
disconnected
A problem in the wiring or fuses.
There is no power to the Car Call
circuits on the HC-CIO board.
Check the Car Call Bus fuse. Check the wires that go to the Car Call Power
inputs on the HC-CIO board in the controller.
(11)
Speed governor
activated
The overspeed governor has
activated, opening the safety circuit.
Check the overspeed governor.
(12)
Drive temperature
sensor fault
The Drive Temperature Sensor
(DTS) input is activated. This
sensor monitors the temperature
inside the IMC-S25 and IMC-G233
drive units.
Verify the temperature inside the drive unit. Check the fan on the drive unit.
Check for a faulty temperature sensor inside the drive unit.
(18)
Photo Eye Failure Stuck photo eye input. Check the photo eye circuitry and wires.
(1F)
Timed out of
service
The T.O.S. timer has expired. Can
be caused by a faulty photo eye,
call button or other door opening
device.
The timer is used to take the car out of service when the car is held at one
floor excessively. Typically this occurs when the doors are held open by
continuous activation of the photo eye, a call button, or another reopening
device. Check for proper operation of the devices mentioned.
(22)
Hoistway safety
device activated
One of the hoistway safety devices
has activated, opening the safety
circuit (e.g., pit stop switch, car and
cwt buffers switches, up/down final
limit switches).
Check all hoistway safety devices. Refer to controller wiring prints for
applicable devices.
(24)
Overload condition,
car is overloaded
The Overload input (OLW) is
activated, or perceived percentage
of load in the car has exceeded the
threshold value set for overload
condition.
Discrete OLW input (wired to a load weigher contact): Check the status of
the OLW input, and determine if the status of the input is appropriate
relative to the load in the car.
Analog load weigher: Check the perceived load percentage using the on-
board diagnostic station. Determine if the value displayed (percentage) is
appropriate relative to the load in the car.
(32)
Drive Fault 1 The heat sink inside the SCR (12-
Pulse) drive has exceeded the
allowed temperature.
Check the fans on the left hand side of the SCR drive. They normally run
when the RE relay picks or the temperature on the heat sink reaches a
certain threshold. If fuse FD1 inside the SCR drive opens, the fans will not
operate. If the normally open auxiliary contact from the M-contactor (see job
print page -SCR) does not make up, the fans will not operate when RE
picks.
(33)
Brake Pick Failure The car is shut down due to the
BPS input being seen as activated
during three consecutive runs
indicating the brake is not fully
picked. (BPS is high)
Check the brake pick switch for proper operation (the contact should open
when the brake is fully picked). Check the status of the BPS input, and
determine if the status of the input is appropriate (deactivated) when the
brake is picked.
(3C)
The Level Down
computer input is
ON
Comes on normally when the car is
just above a floor. If the car is level
with the floor and a message
appears, it is usually the result of a
switch or sensor problem.
Inspect the LD switch or sensor on the landing system and the placement
of the landing system vane or magnet for that floor.
