C.5 Testing Alarms
In the Service section of the Main screen and Unit
screens, the operator is enabled to test each alarm
and shutdown event. When an alarm/shutdown
event is selected to test, the actual alarm/shutdown
is latched. At this point, the system responds as if
an actual alarm/shutdown has occured.
CAUTION: If testing a shutdown event, the
compressor being tested will shut down.
For an alarm/shutdown event, the following will
occur (in addition to the compressor shutting
down for a shutdown event):
•
The horn will initiate.
•
All appropriate control screens will show the
alarm/shutdown condition.
•
An alarm/shutdown signal will be sent to the
Master alarms.
•
The operator must respond and relatch the
alarm/shutdown signal by pressing the "reset"
button on the appropriate main screen or unit
screen.
•
A History item will be created that shows
the "Test" alarm/shutdown event and a
subsequent event for the correction of the
"Test" item.
