Common Fault Clearing Procedures
DIP SWITCH 1 + RESET – If the Controller gets stuck in a non-normal
mode (i.e. Fire Phase I, Earthquake, etc.), verify the required inputs
are connected or jumped out, set Dip Switch #1 (Dip A) to ON and then
press the RESET button on the SRU board. After pushing RESET turn
Dip Switch 1 to off. Latched faults can sometimes be cleared by
changing the mode between Normal and Inspection at the machine
room controller or car top inspection station.
ROPE GRIPPER WON’T RESET – Perform “Dip1+Reset” resolution
above on cartop SRU board.
ACTIVE FAULTS – A red LED flashing on the SRU board means a Fault
or an Alarm condition exists.
a. The faults are logged under MAIN MENU | FAULTS | LOGGED. If
the car does not move, look under MAIN MENU | FAULTS |
ACTIVE and record the fault number (Fxx).
b. When the LCD displays Axx (A57, for example) this indicates an
Alarm Condition. This is not an active fault but rather an
information message indicating a condition to be addressed.
c. When the LCD displays Fxx (F49, for example) this indicates an
Active Fault. The car will not run so long as an active fault is
present. This condition must be corrected before the car may
resume operation.
