Table 6-0: Main CPU Faults
Possible Cause/Suggested Fix
The car is on a door zone and at the top floor but the UT-1
input (from the Main CPU count) did not activate (go off).
• The Up slowdown count for the top floor is set incorrectly.
Review the hoistway slowdown table and if the value is
incorrect, relearn the top floor position.
UT Limit from the NTS
processor turned off
before the normal
slowdown point was
reached.
• The UT limit from the NTS processor is too far from the top
landing. Adjust the UT limit closer to the landing by changing
the NTS UT limit count and the relearning the top floor.
• The slowdown position is set too close to the top landing.
Adjust the top floor slowdown count in the Hoistway Table
Floor & SD Counts menu.
