CODE
FAULT DESCRIPTION
RED-INS or
RED4INS
Redundancy Fault in the Inspection Door Bypass circuits. One of the inputs that
monitors the circuits that bypass the Door Contacts on Inspection or Access
operation was closed when the car was not on Inspection or Access, or terminal 4
was not hot. Check the Door Contact circuit for jumpers or shorts. Cycle the
power to reset the fault.
NOTE
: If 2010 ANSI Code is enabled, and the setting to
require manual resets on Redundancy Fault is enabled, then shutdown faults must
be reset by momentarily turning on the CPU DIP Switch #4, or by momentarily
jumping the Fault Reset Input.
NOTE: The Fault Log Status Signals for this redundancy fault are
custom, to help determine the cause of the fault. Refer to the
section that describes the Fault Log Status Signals for a description
of the signals.
This fault can be disabled by turning on Switch 3 on the CPU Slide Switch S2. This
also turns on the Fire Buzzer output, as a reminder to turn off the defeat.
BAD OIL
Low Oil Switch Fault or Oil Temperature Fault. The Low Oil Switch closed or the
Oil Temperature Switch opened. The car will return to the lowest landing and shut
down. To reset the fault, cycle the power to the controller.
NOTE
: If 2010 ANSI
Code is enabled, then shutdown faults must be reset by momentarily turning on
the CPU DIP Switch #4, or by momentarily jumping the Fault Reset Input.
OIL SW.
Low Oil Switch Fault. The Low Oil Switch closed. The car will return to the lowest
landing and shut down. To reset the fault, cycle the power to the controller.
FLOOD
Flood Switch tripped. This will shut the car down at the designated Flood landing.
The Flood Landing is the second landing by default, but can be changed to the
third landing or the top landing by setting the appropriate bit feature. Flood
operation is cancelled when the Flood Switch input goes low.
FAULT18
This is a custom fault reserved for future use. If it used on a specific job, it will be
described on the “MH
-
3000 Settings” sheet in the schematic.
Fault18 is often used to indicate the car has done a Jack Resynchronization, if this
feature is provided.
FAULT19
This is a custom fault reserved for future use. If it used on a specific job, it will be
described on the “MH
-
3000 Settings” sheet in the schematic.
IOFLT??
I/O Board Fault. The I/O boards did not communicate properly with the CPU. The
two numbers after “IOFLT” indicate which boards failed. Refer to the table shown
below to determine which board or boards have failed. To check Board 8, see the
notes in the troubleshooting section. Check the Address Switches for all boards.
Check the setting in the CPU for the number of I/O Boards. Check the cables
between boards.
NOTE: If the boards NEVER communicate, a fault will not be logged,
since the fault is ignored during power up. The fault is only logged
if the boards were communicating properly and then stopped.
