9.12 Testing Compressor Excessive Run Time Alarms
NOTE:
All testing values are based on default Air-dryer settings, if settings have
been changed, adjust testing values accordingly.
Reference the Appendix Section
14.2 for Limits and Defaults.
NOTE:
For this test, allow the Display Screen to cycle through the information
screens.
9.12.1
Remove Front Panel (see section 8.10.2 )
9.12.2
Start timing when the compressor(s) turns on.
9.12.3
Pull the ring handle on the
Safety Relief Valve (when
necessary) to keep the Tank
Pressure (
TANK
) from
reaching
50 PSI
.
This prevents the
compressor(s) from shutting
down.
When the compressor(s) runs
for 3:00 minutes (unless
adjusted to a different Set
Point by the user), a
Compressor Excessive Run
Time (
LAST RUN
) alarm
should appear on one or both of the System screens.
9.12.4
Press the
RESET Button
to clear the alarm.
9.12.5
Reinstall Front Panel.
If you are unable to create a Compressor Excessive Run Time (LAST RUN)
alarm as described, see section 13.18 for troubleshooting information.
