3.7 ALARMS
When an alarm occurs, the alarm indicator will light
and display will show actual alarm message. If
alternately multiple alarms have occurred the display
will show SCROLL FOR ALARM. 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
SET button. Any exceptions to the above will be
explained in the alarm description.
The following is a list of the alarm messages.
1) LOW SUMP PRESS
This will occur if the unit is running and sump
pressure is too low.
2) HIGH AIR PRESS
This will occur if the unit is running and sump
pressure is greater than unit rated operating
pressure plus 20 psig (1.4 bar), plus the separator
pressure drop, or the line pressure is 15 psig (1.0
bar) above the rated pressure.
3) HIGH AIREND TEMP
This will occur if airend discharge temperature is
greater than 228°F (109°C).
4) STARTER FAULT 1SL (2SL)
This alarm will occur if the starter contacts open
while the unit is running. This alarm will also occur if
the unit is given the stop command and the starter
contacts do not open. 1SL refers to the auxiliary
circuit on starter contactor 1M. 2SL refers to the
auxiliary circuit on starter contacts 2M and 1S.
5) MAIN MTR OVERLD
This will occur if a motor overload is sensed.
6) FAN MTR OVERLOAD
This will occur if a fan motor overload is sensed.
7) TEMP SENSOR FAIL
This will occur when the sensor temperature is
recognized as missing or broken.
8) REMT STOP FAIL
This will occur if the momentary remote stop switch
does not disengage by the time the unit attempts to
start.
9) REMT START FAIL
This will occur if the momentary remote start switch
does not disengage by the time star-delta transition
occurs.
10) CK MTR ROTATION
This alarm will occur if a unit is started and
compressor has incorrect rotation.
11) CALIBRATION FAIL
This alarm will occur if the sensor calibration routine
is executed and the sensor reading exceeds 10% of
scale.
12) NO CONTROL POWER
This alarm will occur when the controller senses a
loss of control power.
13) PRES SENSOR FAIL
Whenever the pressure sensor is recognized as
missing or broken, a pressure sensor failure alarm
will occur.
14) LOW UNLOAD SUMP
This alarm will occur if the unit is running unloaded
and sump pressure is less than 15 psig (1.0 bar).
INITIAL CHECK ALARMS
15) HIGH AIREND TEMP
This will occur if airend discharge temperature is
greater than 217°F (103°C).
This alarm will only occur when the machine is not
running. When it occurs, the message MUST COOL
DOWN is added to the alternating group of alarm
messages.
EMERGENCY STOP
This will occur when the EMERGENCY STOP button
is engaged. The alarm indicator will light and display
will show:
EMERGENCY STOP
Disengage the EMERGENCY STOP button and
press the SET button twice to reset this alarm.
