9.0 OPERATING INSTRUCTIONS
9.15 ALARMS
When an Alarm occurs, a large exclamation mark in
a triangle will flash on the display screen. The display
message will indicate what caused the Alarm.
The compressor will stop and cannot be re-started again
until the alarm condition no longer exists and the alarm
message reset.
Pressing the STATUS button will display the STATUS
screen. The presence of the ALARM button indicates that
an Alarm condition still exists. Alarm Status is the list of
machine operating conditions that existed at the time of
the Alarm.
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 ALARM button will return the
display to the Alarm screen and the RESET button.
The Alarm needs to be reset by the operator by pressing
the RESET button twice. Any exceptions to this are
explained in the alarm descriptions.

MAIN MENU
The possible Alarm messages are as follows;
EMERGENCY STOP-
This will occur if the Emergency
Stop button is engaged. The button must be disengaged
before the alarm can be cleared.
BLOWER FAULT-
This will occur if a blower fault is sensed.
HIGH AIREND DISCH TEMP-
This will occur if the airend
discharge temperature is greater than 109°C (228°F).
REMOTE START FAILURE-
This will occur if the Remote
Start button is pressed after the machine 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 -
This will occur if a sensor is
recognized as missing or broken.
VSD FAULT -
The VSD fault is read from the drive. The
Intellisys will read the status menu of the variable
speed drive. If a fault condition is returned in the status
information, the Intellisys will issue a VSD FAULT alarm
and display the number of the fault condition.
CONTROL POWER LOSS -
This will occur if the control
circuit is broken by a bad connection or safety switch (e.g.
HAT Switch/ Phase Monitor). Any fall of voltage below
100VAC for more than 2 seconds will cause this alarm trip.
STOP FAILURE -
This will occur if the compressor should
be stopped but the motor is still running above minimum
speed 4 seconds after the stop signal is given.
HIGH START PRESSURE -
If the sump pressure is above
100 psi (6.9 bar) when the compressor starts, the Intellisys
will open the blowdown valve during the first few
seconds of starting (3 to 7 seconds). If the sump pressure
does not fall to 100 psi (6.9 bar) during that time period,
this shutdown will occur.
CHECK MOTOR ROTATION -
This will occur if the Intellisys
reads a negative speed from the VSD when starting .
VSD COMMUNICATION FAILURE -
This will occur if the
Intellisys does not receive a response from the VSD when
requesting information. This alarm will take about
8 seconds to occur.
VSD INITIALIZATION FAULT -
Will occur if the Intellisys is
unable to establish communications with the VSD after a
power up.
LOW SUMP PRESSURE -
Will occur if the compressor is
operating and the sump pressure drops below 15psi
(1.03 bar) for 15 seconds.
REPLACE COOLANT FILTER -
This will occur if the coolant
filter is blocked and requires changing.
INCORRECT VSD TYPE -
Will occur at power up if the VSD
type does not match the size of the compressor 125HP
(90kW) machines and above also have the following
alarm messages;
CONTROL POWER LOSS -
This will occur if the
compressor should be running and the AC input voltage,
as read from the VSD, falls below 100 VAC. There is a delay
of 2 seconds on this alarm in case the power quickly
returns. An open HAT switch or phase monitor are two
things that can cause this alarm.
STOP FAILURE -
This will occur if the compressor should
be stopped, but the motor speed has not dropped below
the minimum motor speed setpoint. The Intellisys will
wait 4 seconds for the compressor to stop before issuing
this alarm.
HIGH INTERSTAGE PRESSURE -
If the interstage pressure
is over 75 psi while the unit is running and the unit is a
two stage.
