Table 6-0: Main CPU Faults
Faults
Description
Possible Cause/Suggested Fix
UL DL Dist Too Large
The UL and DL
distance settings are
the number of counts
the car runs after the
UL and DL dead level
inputs are active. If
the UL or DL distance
is set greater than 2
inches, the controller
will get this error
when it attempts to
verify the hoistway
table.
• The UL and DL distances are set in the Hoistway Tables
menu on the LCD display interface. Select the UL & DL
Distance menu and then set the UL or DL distance to the
proper value.
UL Failed On Fault
UL Failed On Fault.
The UL input did not
go off during a run.
The UL input is set
from a count from the
APS selector.
• The APS selector did not change count during a run. Check
for faults related to the APS selector. Verify that the APS
selector counts change while the car is running.
• The elevator did not leave the floor on a run attempt.
Verify that the elevator can run from the landing. Check the
fault log for another fault that could prevent the car from
running.
UL, DL & DZ
Off at FL
UL, DL & DZ inputs off
at floor. The car thinks
it should be at a floor
or is at a floor and all
the floor inputs have
turned off.
• Verify that the Main CPU is communicating with the APS
selector.
• Verify that the Main CPU has a valid floor table.
Up Directional Fault
Car unexpectedly hit
the Up Normal Limit
while running up.
• The Safety PAL detected a fault condition and turned off
the UN output from the NTS processor.
• The NTS proce
ssor detected a fault condition and turned
off the UN output.
• APS Selector communications loss to the Main CPU.
• APS Selector communications loss to the NTS processor.
• Selector not reading the correct position from the tape.
User Variable Init
User variable
initialization
User related parameters such a password and telephone
numbers are being initialized. This error occurs on the first
time the GALX-1132 CPU board is being powered up.
