OPERATING INSTRUCTIONS
WARNING
Make sure that all protective covers are in place.
Cooling air flow exhaust may contain flying debris. Safety
Protection should be worn at all times to avoid injury.
STARTING
1. Turn selector switch to ON position. The compressor will start and
then load automatically.
NORMAL STOPPING
1. Turn selector switch to the OFF position. This allows the unit to run
in automatic fan control mode.
EMERGENCY STOPPING
1. Press EMERGENCY STOP button (4) and the compressor and fan
will stop immediately. This button is not to be used for stopping under
normal operation.
2. Turn off electrical isolator or disconnect.
CAUTION
Never allow unit to stand idle with pressure in receiver. The
unit will blowdown to relieve pressure between the compression
module and the min pressure check valve.
INDICATOR SYMBOLS & OPERATION
Symbols
LCD Numeric display Indicates time of day, machine run hours,
running maintenance timer, and Package Discharge Pressure.
LCD Bar Graph Display Displays the current percentage of time until
maintenance is due. A 10 segment bar graph indicates 0 to 100% in
increments of 10%.
LCD Icon Display Icons are used to indicate when and what type of
service should be performed. The icons descriptions are as follows:
Wrench icon to indicate when maintenance is due or the
maintenance timer is being displayed.
Motor icon to indicate when the VFD has indicated a
drive fault.
PSI Icon to indicate when the pressure indication is being
displayed in pounds per square inch.
Icon to indicate when the pressure indication is being
Bar
displayed in bar.
kPa Icon to indicate when the pressure indication is being
displayed in kilopascals.
LED LED Lamp indicating when maintenance is due or a fault has
occurred.
Operation
The LCD digital indicators, bar graph, icons and the LED will only be
visible when power is turned on to the compressor. When compressor
power is on, 24 Vdc will be applied to the "Power" input completely
powering the indicator and no internal battery power will be required for
operation.
When compressor power is removed, an internal battery will keep the
Real Time Clock (RTC) and Annual Maintenance timer running until
power is turned on to the compressor. The internal battery will maintain
the RTC and the Annual Maintenance timer for a minimum of 7 years
of compressor off time. At such time as a replacement battery is
required, the complete indicator will need to be replaced.
The indicator device performs four separate functions.
(1) Hour meter
IRN 7.5 - 15 HP (5.5 - 11 kW)
(2) Maintenance Indicator
(3)Package Discharge Pressure Indicator
(4) Real Time Clock
PM indication.
At power up the indicator will default to the Package Discharge
Pressure indication in the selected engineering units. If engineering
units have not been previously selected, PSI will be the default
engineering units.
HOUR METER FUNCTION
The indicator will function as a standard hour meter indicating the
number of hours the compressor has run throughout it's entire lifetime.
This will be an accumulative hours indication and count hours only
when 24Vdc is applied to the "Power" input and the "Run Signal" input
is pulled high (24Vdc).
An hour meter icon will be visible on the display when the numerical
hour meter indication is being displayed. The hour meter icon will flash
when the "Run Signal" input is pulled high indicating the hour meter
timer is running.
MAINTENANCE INDICATOR
The indicator will indicate when maintenance is to be performed on the
compressor based on a predetermined maintenance schedule, or by
the Drive Fault signal input. If Drive Fault signal is activated, LED will
illuminate without flashing.
Scheduled Maintenance
A bar graph display will continuously indicate the percentage of the
maintenance interval remaining until the next service is due. The bar
graph will default to full scale, 100%, indication and will progressively
reduce to 0% as the service life expires until the maintenance time
interval is achieved. The bar graph will display the maintenance value
closest to reaching its respective predetermined maintenance interval
time.
Once the indication reaches 20% of the preprogrammed time, the LCD
bar graph 10% and 20% segments and the Wrench icon
alternately flash until maintenance is performed and the timers are reset.
An LED will be visible from the front panel. Once the % Remaining
indication reaches 10% of the preprogrammed time, the LED will flash
until the indication reaches 0% of the preprogrammed time interval.
Once 0% is reached, the LED and wrench icon will be on continuously
and remain on until maintenance is performed and the timers are reset.
Maintenance intervals are based from two separate timers.
(1) Runtime Maintenance timer
(2) Annual Maintenance timer
Run time Maintenance Timer
2,000 hours of actual compressor runtime. This timer runs anytime the
"Run Signal" input is pulled high. (24Vdc).
Annual Maintenance Timer
8760 hours (1 yr) after compressor installation regardless of how long
the compressor has been powered and running. This timer runs
continuously and reset once the compressor has been installed and
properly initialized.
Once service has been performed, the customer or service technician
will reset the indicator by a sequence of panel button presses. This will
reset both the Run time Maintenance and the Annual Maintenance.
