The possible Warning messages are as follows;
AIREND DISCHARGE TEMP
– This will occur if the Airend Discharge (2ATT)
exceeds 97% of the alarm limit, 228°F (109°C) and is not adjustable.
CHANGE COOLANT FILTER – This warning will occur if the high side pressure
is 20 psig (1,4 bar) greater than the low side pressure of 1 DPS and the
Injected Coolant temperature (2CTT) is greater than 120°F (49°C).
CHANGE INLET FILTER
– This will occur if the Inlet Vacuum (1AVPT) is greater
than 0,7 psig (0,05 bar) and the compressor is fully loaded (inlet valve is
completely open).
CHANGE SEPR ELEMENT
– This warning will occur if the pressure on the
Separator (APT) is 15 psig (1,0 bar) greater than the pressure at the Package
Discharge (4APT) and the compressor is fully loaded.
HIGH DISCHARGE PRESS – This can occur if the compressor’s loading
function is being controlled by a host device such as a sequencer or an ISC.
This warning will occur when the package discharge pressure is above the
maximum offline pressure (rated pressure plus psig (0,2 bar)) for more than
seconds. This warning will cause the compressor to unload. The host device
will not be able to load the compressor until the package discharge pressure
falls to the rated pressure of the compressor.
SENSOR FAILURE 4ATT
– This will occur if the Package Discharge
Temperature Sensor (4ATT) is missing or broken.
TRIPS
When an Trip occurs, the word TRIP will flash on the display screen and
appear in large letters as shown. The display message will indicate what
caused the Trip.
Figure 25: Trip Screen
Pressing the STATUS button will display the STATUS screen. The presence of
the TRIP button indicates that an Trip condition still exists. Trip Status is the
list of compressor operating conditions that existed at the time of the Trip.
Figure 26: Trip Screen Detail
The name and value of each of the items listed can be seen by moving the list
up and down using the arrow buttons. Pressing the TRIP button will return
the display to the Trip screen and the RESET button.
The Trip needs to be reset by the operator by pressing the RESET button
twice. Any exceptions to this are explained in the Trip descriptions.
The possible Trip messages are as follows;
CHECK MOTOR ROTATION
– This will occur if the compressor is started and
the compressor has incorrect rotation.
CONTROL POWER LOSS – This will occur if the controller detects a loss of the
110 VAC control power.
EMERGENCY STOP – This will occur if the Emergency Stop button is engaged.
The button shall be disengaged before the trip can be cleared.
FAN MOTOR OVERLOAD
– This will occur if a fan motor overload is sensed.
HIGH AIREND DISCH TEMP
– This will occur if the airend discharge
temperature is greater than 228°F (109°C).
HIGH SUMP PRESSURE
– This will occur if the sump pressure is above offline
pressure by 25 psig and sump pressure drop is more than 25 psig. Can also
occur if sump pressure is above 165 psig.
LOW SUMP AIR PRESSURE
– This will occur if the compressor is running fully
loaded and the sump pressure drops below 20 psig (1,4 bar).
LOW UNLOAD SUMP PRESS
– This will occur if the compressor is running
unloaded and the sump pressure is less than 15 psig (1,0 bar) for 15 seconds.
MAIN MOTOR OVERLOAD – This will occur if a drive motor overload is
sensed.
MEMORY FAULT
– This will occur if the controller has determined some of the
data stored in memory contains unacceptable values. When this occurs, the
sensors should be calibrated and all the set points checked. It is normal for
this trip to occur after changing controller software.
REMOTE START FAILURE
– This will occur if the Remote Start button is
pressed after the compressor is running or if the Remote Start button remains
closed.
REMOTE STOP FAILURE – This will occur if the Remote Stop button remains
open and either Start button is pressed.
SENSOR FAILURE 1AVPT (or 3APT, 4APT, 2CPT,5CPT,6CPT 2ATT)
– This will
occur if a sensor is recognised as missing or broken. This does not apply to
sensor 4ATT.
HIGH INLET VACUUM – This will occurs if inlet vacuum is greater than
1.8 psig for compressors with high dust factor, the threshold is 1.8 psig.
Prior to starting
1. Check the coolant level in the sight tube/glass. Add coolant if
necessary.
2. Ensure that the discharge air isolation valve is open.
. Switch on the main electrical isolation switch. The power on
indicator will illuminate, indicating that the line and control
voltages are available.
