Section VIII - Power$ync II™ Operation
Shutdown Log Messages | STAGE 2 IN HAT SHUTDOWN |
The shutdown log allows the operator to view service and shutdown alarms in the reverse order of occurrence. The log gives a plain English message that will identify the source of the alarm. These messages include:
EMERGENCY STOP PRESSED
This message will appear when the red, mushroom- shaped emergency stop button has been pressed. The nature of the emergency should be determined and corrected before attempting to restart the compressor. The emergency stop button will lock in when pressed and must be turned to release. Once the button is released, the compressor can be restarted by pressing the green start button.
NOTE
The HAT snapdisk probes or the coolant flow switch will give the same error mesage.
This indicates that a high temperature condition was detected. The temperature probe at the input to STAGE 2 detected temperature above the set trip point. The cause of the high temperature condition MUST be determined and corrected before the compressor is restarted.
STAGE 1 DISCHARGE HAT SHUTDOWN
This indicates that a high temperature condition was detected. The temperature probe at the output of STAGE 1 detected temperature above the set trip point. A high air temperature condition was detected above the set trip point. The cause of the high temperature condition MUST be determined and corrected before the compressor is restarted.
STAGE 2 DISCHARGE HP SHUTDOWN
DISCHARGE HAT SHUTDOWN
This indicates that a high temperature condition was detected. There are temperature probes in the package discharge. A high air temperature condition was detected above the set trip point. The cause of the high temperature condition MUST be determined and corrected before the compressor is restarted.
This message will be displayed should the pressure at the discharge of STAGE 2 exceed a trip point. In addition to the HP shutdown, a safety relief valve will vent tubing pressure before internal pressure levels approach maximum safe operating pressure of the system components.
