Safety Shutdown - Carrier 17/19EX Start-Up, Operation And Maintenance Instructions Manual

Safety Shutdown

A safety shutdown is identical to a manual shutdown with the exception that the LID will
display the reason for the shutdown, the alarm light will blink continuously, and the spare alarm
contacts will be energized. A safety shutdown requires that the RESET softkey be pressed in
order to clear the alarm. If the alarm is still present, the alarm light will continue to blink. Once
the alarm is cleared, the operator must press the CCN or LOCAL softkeys to restart the
machine.
CAUTION
Do not reset starter loads or any other starter safety for 30 seconds after the
compressor has stopped. Voltage output to the compressor start signal is main-
tained for 10 seconds to determine starter fault.
