9.0 OPERATING INSTRUCTIONS
9.12 WARNINGS
When a WARNING occurs, a large question mark will flash
on the display screen.
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 that a WARNING still exists.
A WARNING will not cause the unit to shut down. The
unit will continue to run in its normal operation and the
WARNING will remain displayed until reset.
A Warning needs to be reset by the operator by pressing
the RESET button twice.
The possible Warning messages are as follows;
HIGH AIREND DISCHARGE TEMP -
This will occur if the
Airend Discharge exceeds 97% of the alarm limit, 109°C
(228°F) and is not adjustable.
CHANGE COOLANT FILTER -
This warning will occur if
the high side pressure is 1.4 bar (20 psig) greater than the
low side pressure.
CHANGE INLET FILTER -
This will occur if the Inlet
Vacuum is greater than 0.05 bar (0.7 psig).
CHANGE SEPR ELEMENT -
This will occur if the pressure
differential across the separator is 1.0 bar (12 psig).
SENSOR FAILURE -
This will occur if a sensor is
recognized as missing or broken.
HIGH DISCHARGE PRESS -
Will occur if the unit is under
the control of an external device, such as an ISC, and the
discharge pressure is greater than the immediate stop
pressure.
AUXILIARY WARNING 1 or 2 -
Will occur if the auxiliary
warning input closes.
REMOTE PRESSURE SENSOR FAILURE (option) -
This will
occur if the remote pressure sensor fails. If this happens,
the lntellisys will start using the package discharge
pressure sensor to measure system pressure.
CONDENSATE DRAIN ERROR -
On two stage units, this
will occur if the condensate drain error contacts close
while the unit is running.
HIGH VSD TEMPERATURE -
This will occur if the drive
temperature reaches or exceeds 57°C or 133°F.
9.13 SERVICE WARNINGS
SERVICE -
Service warnings occur when the unit has
operated a certain number of hours, based on the total
hours, or has operated for a certain number of months,
based on the real time clock. Service warnings can have
multiple levels, depending on the service level selection.
This will be set prior to the compressor being shipped
from the factory. When a service warning occurs, contact
your local IR service representative.
9.14 INITIAL CHECK ALARMS:
The following alarms will only occur when the machine
is not running. These alarms are related to high
temperature, power loss, and sensor calibration. They will
have the same display mode as other alarms.
HIGH AIREND DISCH TEMP-
Will occur if airend
discharge temperature is greater than 95% of 109°C
(228°F).
CHECK SETPOINTS -
Will occur if the controller has
determined that some of the data stored in memory
contains unacceptable values.
INVALID CALIBRATION -
Will occur if the sensor zero
value is -10% to +1% of its scale. See Sensor Calibration.
