9.0 OPERATING INSTRUCTIONS
Pressing the WARNING button will return the display to
the WARNING screen and the RESET button.
A Warning needs to be reset by the operator by pressing
the RESET button twice.
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
machine is fully loaded (inlet valve is completely open).
CHANGE SEPR ELEMENT
– This warning will occur if
the pressure on the Separator (3APT) is 15 psig (1,0 bar)
greater than the pressure at the Package Discharge
(4APT) and the machine is fully loaded.
HIGH DISCHARGE PRESS
– This can occur if the
machine’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 3 psig (0,2
bar)) for more than 3 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 machine.
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 above.
The display message will indicate what caused the Trip.
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 machine
operating conditions that existed at the time of the Trip.
