Carrier 17/19EX Manual De Usuario
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.
