EXERCISE OPERATION (775) Description: Car has been idle for a user-defined time and is now perform-
ing a user-defined number of exercise operation runs. During an exercise
run, the car lowers to the bottom landing, then proceeds to the top landing
and back down to the bottom without cycling the doors. The number of
exercise runs is user defined.

Check the user defined timer and number of exercise cycles in CONFIG 01
> ELEVATOR FEATURES > EXERCISE TIMER and CONFIG 01 > ELEVATOR
FEATURES > EXERCISE CYCLES.
EXCESSIVE FAULTS (117) Description: This fault is generated when there are more than ten faults
that resulted in an emergency, controlled or ASAP stop. The counter resets
if the car makes ten normal runs without any faults. The car is taken out of

next available floor and cycle the doors to let the passengers out. Once at a
floor, the Excessive Faults Shutdown fault is activated and the car will
remain shut down until the Fault Reset button is pressed, Inspection is tog-
gled or power to the controller is cycled. Fault-bypassed in Construction/
