COMPRESSOR ALARMS
When an alarm occurs, the display will alternately show the following messages:
the actual alarm message, PRESS TEST-FOR VALUES, and PRESS RESET
2X-CLEAR. If multiple alarms have occurred the display will show SCROLL
FOR ALARMS instead of the alarm messages. In this situation the up and down
arrows will be used to view the alarm messages. All alarms (with the exception
of the emergency stop) will be reset by twice pressing the RESET button. Any
exceptions to the above discretion will be explained in the alarm description.
The following is a list of the alarm messages.
1) HIGH INLET VACUUM
This will occur if the unit is running unloaded and 1AVPT is greater than
13.8 psi (vacuum) activated after *
∆
transition plus 2 seconds.
2) CK INLET CONTROL
If the unit is running unloaded and 1AVPT is less than-3 psi (vacuum), this
will occur.
3) LOW UNLOAD SUMP PRESS
This will occur if the unit is running unloaded and 3APT is less than 15
psig.
4) HIGH SUMP AIR PRESS
This will occur if the unit is running and 3APT is greater than the rated
pressure plus 23.
5) HIGH A/E DISCH TEMP
This will occur if 2ATT is greater than 228 degrees.
6) STARTER FAULT
This alarm will occur if the starter contacts open while the unit is running.
This alarm is not checked during the first 2 seconds of operation. This
alarm will also occur if the unit is given the stop command and the starter
contacts do not open or the unit has the no starter option and 1S contact
does not open within 30 seconds after starting.
7) MAIN MOTOR OVERLOAD
This will occur if a motor overload is sensed. This is a 5V DC input.
8) FAN MOTOR OVERLOAD
This will occur if a fan motor overload is sensed. This is a 5V DC input.
9) CK MOTOR ROTATION
This alarm will occur if a unit is started and 1AVPT is less than 1 psi
(vacuum). This alarm is not checked during the first 2 seconds of
operation.
10) CK INLET CONTROL SYS
If the inlet valve is to move to the fully open or fully closed position and
the limit switch for that position is never made, this alarm will occur.
11) INLET VALVE ROTATED
This alarm will occur if unit is given the start command and the inlet valve
is not in the fully closed position.
