Table 6-0: Main CPU Faults
Faults
Description
Possible Cause/Suggested Fix
Invalid DN or DT Cnt
Invalid DN or DT
Count. The position
count for DN is
greater than the count
for DT
• Invalid hoistway learn or the hoistway
learn is not
complete. Re-learn the hoistway or complete the hoistway
learn.
• The bottom terminal floor limits are calculated and stored
when the bottom floor is learned. Bring the car to the
bottom floor and re-learn the floor position.
• If this problem
is not corrected with a hoistway learn,
contact the factory
Invalid Floor Count
Invalid Floor Count.
The floor count of the
floor above must
always be larger than
the floor below. An
above floor count was
lower than the floor
below in the floor
hoistway table.
• Invalid hoistway learn or the hoistway learn is not
complete. Re-learn the hoistway or complete the hoistway
learn.
• Check the hoistway table and verify that the floor position
counts are getting larger as the floor number increases, i.e.,
the third floor should be a larger number than the second
floor.
• If this problem is not corrected with a hoistway learn,
contact the factory
Invlid Top Floor Cnt
Invalid Top Floor
Count. The top floor
count is zero.
• Invalid hoistway learn or the
hoistway learn is not
complete. Re-learn the hoistway or complete the hoistway
learn.
• Verify that the top floor count is correct distance from the
bottom.
• Bring the car to the top floor and re
-learn the floor
position.
• If this problem is not correcte
d with a hoistway learn,
contact the factory
L1 Low Line Voltage
L1 Line Voltage Low
• Voltage Sensor Board Related. Voltage being monitored on
L1 dropped below the setting for parameter ' Low Line Volt '
L2 Low Line Voltage
L2 Line Voltage Low
•
Voltage Sensor Board Related. Voltage being monitored on
L2 dropped below the setting for parameter ' Low Line Volt '
L3 Low Line Voltage
L3 Line Voltage Low
• Voltage Sensor Board Related. Voltage being monitored on
L3 dropped below the setting for parameter ' Low Line Volt '
Level Stop Cnt Fault
Leveling stop fault
occurred from
incorrect count. As the
car was leveling off
the pulses, UL or DL
turned off.
• The UL or DL Distance value set too high or the APS Dead
Zone parameter is set to small. Increase the dead zone or
decrease the UL or DL distance setting.
• This fault can
sometimes occur from multiple re-levels. Check the leveling
setup of the car.
