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 (.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 12 psig
(.8 bar) greater than the pressure at the Package
Discharge (4APT), and the machine is fully loaded.
When a Warning occurs, a question mark will flash on
the display screen and appear in large letters as
shown above. The display message will indicate what
caused the warning.
If multiple Warnings exist, the small up/down arrows
will appear in the upper right corner of the display
screen. The multiple Warnings can be seen by
pressing the up and down arrow buttons. Pressing the
STATUS button will display the CURRENT STATUS
screen with the WARNING button indicating a Warning
still exists.
?
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 lSC. This warning
will occur when the package discharge pressure is
above the maximum offline pressure (rated pressure
plus 3 psig [.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
recognized as missing or broken.
AUXILIARY 1 (OR 2) - This warning will occur if either
of the auxiliary contacts closes.
HIGH SUMP/LINE DIF - This warning will occur if the
compressor is running loaded, the injected coolant
temperature is greater than or equal to 120 deg. F,
(49°C) the package discharge pressure is greater than
90 psig, (6.3 bar) the sump pressure is greater than the
compressor’s rated pressure, and the sump pressure is
25 psig (1.8 bar) or more above the package discharge
pressure.
