GENERAL INFORMATION

GENERAL OPERATION

The Sierra compressor is an electric motor driven, two stage,
dry screw compressor complete with accessories piped, wired
and baseplate mounted. It is a totally self–contained oil free
air compressor package. A standard compressor is composed
of the following:

Inlet air ltration
Compressor and motor assembly
Pressurised oil system with cooler
ON/OFF line capacity control system
Motor starting control system
Instrumentation
Safety provisions
Intercooler
Aftercooler
Moisture separation rst and second stage
Automatic condensate removal rst and second stage.

The motor and airend are integrally mounted. This assembly
is isolated from the base by rubber isolation mounts. Flexible
pipe connections are utilised where necessary to isolate the
main base and customer connections.

DESIGN PRESSURES

The normal operating pressures for Ingersoll Rand Sierra
compressors are 7.0 bar, 8.5 bar and 10.0 bar (100 psi, 125 psi
and 150 psi). The maximum allowable pressure is 0.2 bar (3
psi) above the normal operating pressure and is shown on the
compressor name plate.

The inter–stage safety valve is set at 3.1 barg (45 psi)
90–150 kW, 125–200 hp or 3.8 barg (55 psi) 200–300 kW,
250–400 hp. The second stage safety valve is set at

11.4 barg (165 psi) max. The design of the pressurised system
is well above the safety valve settings.

DESIGN TEMPERATURES

The standard compressor is designed for operation in
an ambient range of 2 °C to 46 °C (35 °F to 115 °F). When
conditions other than the design levels described are
encountered, we recommend you contact your nearest
Ingersoll Rand Distributor or Air Centre for additional
information.

COMPRESSED AIR SYSTEM

The compressor air enters the compressor through an
opening at the right end of the enclosure. It travels through
a passageway lined with sound–absorbing material to the
air lter. Via a round exible hose, the air passes through the
inlet/unloading valve into the rst stage of the compressor.

The helical rotors compress the air to a pressure of between

1.7 to 2.6 barg (25 to 38 psig). It is discharged into a venturi,
which dampens any pressure pulsations that may be present.

The intercooler then reduces the air temperature before it
enters the second stage. A safety relief valve is also positioned
in this system to guard against an abnormally high inter­stage pressure. A moisture separator is supplied immediately

following the intercooler to remove any condensation that
may occur under certain conditions of ambient humidity and
temperature.

An expansion joint is utilised between the moisture separator
and the second stage.

The second stage further compresses the air to the desired
pressure. The pressure pulsations being dampened in a
venturi. An expansion joint prevents transmitted vibrations. A
poppet type check valve is provided to prevent any backow
of air into the compressor. The aftercooler cools the air to a
suitable temperature, while the discharge moisture separator
removes signicant amounts of condensation.

During unloaded operation, the inlet/unloading valve closes,
via mechanical linkage, the blowdown valve opens, expelling
any compressed air from the package.

CONDENSATE REMOVAL SYSTEM

A moisture separator is located immediately after the
intercooler and aftercooler to collect and eject any
condensation formed from the compressed air.

The condensate is drained through electrically operated
solenoid valves. The opening duration is preset at three (3)
adjustable between 2 and 20 seconds, the interval between
openings may be altered between 60 and 360 seconds,
depending on ambient conditions. If the environment
consists of high temperature and/or high humidity, then the
interval may have to be reduced. The factory set interval is
180 seconds.

The bosses for the manual valves are located on the outside
and rear of the sub–base. These valves are supplied loose
inside the compressor enclosure and need to be connected to
the ports as indicated in the general arrangement drawing. To
check operation of solenoid valves, open the manual bypass
valves momentarily once per day. For extended shutdown
periods, the manual valves should be opened and left open.

Strainers are provided upstream of the condensate valves
to prevent any particles from plugging the solenoid valves.
Before any maintenance is performed on the strainers or
solenoid valves, the strainer service valves should be closed,
in order to isolate from possible high pressure.

LUBRICATION SYSTEM

The oil sump is integral within the gearcase. The oil pump is
a positive displacement gear–type pump, and is driven by
the compressor driven shaft. Therefore, it rotates at the main
motor speed.

See MAINTENANCE section for lubricant specication.

From the pump, the oil travels past a pressure relief valve to
the oil cooler. The pressure relief valve’s function is to prevent
over–pressure of the system. It also regulates oil pressure and
may divert some oil ow back to sump.

At the discharge side of the oil cooler is a thermostatic valve.
This valve mixes the cold oil with hot oil that bypasses the
cooler to provide oil at the optimum temperature to the
bearings and gears.

The oil then passes through a lter to a distribution manifold.
An orice from the manifold determines the oil pressure (2.8
to 3.5 barg) (40 to 50 psig), at normal operating temperature
(54 °C to 68 °C) (129 °F to 154 °F).

The gearcase is vented to a mounted breather. The breather
prevents oil vapour from escaping the sump area. The
breather exhaust is piped to the plenum area of the package.

COOLING SYSTEM (AIRCOOLED)

The intercooler, aftercooler, oil-cooler, fan and motor are
an integral assembly. The heat exchanger and fan are
mounted directly above the compressor assembly. Cooling
air ows through the end of the enclosure, through the heat
exchangers and discharges through the top of the package.

COOLING SYSTEM (WATERCOOLED)

The intercooler, aftercooler and oil-cooler are shell and tube
type heat exchangers. The intercooler and aftercooler are
”water in the shell” design. The oil-cooler employs ”water in
the tube”.

Cooling water ows through each of the three components
in parallel. A water solenoid shut o valve is provided in the
water discharge line from the package.

The tube bundles are removable for ease of cleaning.

ELECTRICAL SYSTEM

The electrical system of the compressor utilises the
microprocessor–based Xe controller. The standard electrical/
electronic components, contained within a readily accessible
enclosure include:

Xe controller

Star–Delta compressor motor starter, with auxiliary
contacts and overload relays

Cooling fan manual motor starter and circuit breaker or
fuses

Power supply board

Main motor overload relay

Control relay control transformer, and fuses.

Star–Delta type starter

By use of the Star–Delta type starter, the compressor motor
can be started and accelerated using a greatly reduced
”inrush” electric current. The starter is completely automatic
and controlled by the Xe controller. Refer to the electrical
schematic.

CAPACITY CONTROL

Automatic unloaded start

The compressor will always start in the unload mode. When
unloaded, the inlet valve is nearly closed, the blowdown valve
is open and the compressor is operating at minimum power.

On–O line control

On–O line control will deliver air at full capacity (compressor
maximum eciency condition) or will operate at zero
capacity (compressor minimum power condition). The
compressor is controlled by the Xe controller responding to
changes in plant air pressure. The Xe controller energises the
load solenoid valve (1SV) to actuate the hydraulic cylinder
and load the compressor whenever plant air pressure drops
below the online pressure set point. The compressor will then
operate to deliver full capacity air to the plant system. If the
plant air system pressure rises to the o line set point of the
Xe, the load solenoid valve is de–energised, the hydraulic
cylinder is de–actuated allowing the machine to unload. The
compressor will continue to run with minimum power draw.

AUTOMATIC START/STOP CONTROL OPTION

Many plant air systems have widely varying air demands or
large air storage capacity which allows for automatic standby
air capacity control.

The Xe system has been designed to carry out this function
utilising a software module. Automatic Start–Stop is standard
on all Sierra compressors.

During periods of low air demand, if the line pressure rises
to the oine set point, the Xe controller begins to time out.
If the line pressure remains above the online set point for as
long as the set time, the compressor will stop. At the same
time, the Automatic Restart warning message will appear
in the display to indicate the comdpressor has shut down
automatically and will restart automatically. An automatic
restart will occur when the line pressure drops to the online
set point.

The oine and online set points and shutdown delay time
are set on the control panel. There is a 10 second delay after
shutdown during which the compressor will not restart even
if line air pressure drops below the online set point. This
is to allow the motor to come to a complete stop and the
controller to collect current data of operating condition. If line
air pressure is below the online set point at the end of
10 seconds, the unit will start unless the load delay timer is set
greater than 10 seconds.

Delay load time

This is the amount of time the line pressure must remain
below the online set point before the compressor will load
or start (if the unit was stopped due to an auto start/stop
situation). This timer will not delay loading after a start or
if the time is set to 0. When the delay load timer becomes
active, the display will switch to line pressure (if not displaying
line pressure at that time) and then display the delay load
countdown. Once the countdown reaches 0, the unit will load
or start and the display will return to line pressure. The display
select arrows are inactive during the delay load countdown.

Automatic start/stop operation

When in operation, the compressor must meet two specic
timing intervals before the Xe controller will stop the unit in
an Automatic Start/Stop situation.

A timer prevents the compressor from automatically starting
more than 6 times an hour by requiring the unit to run at least
10 minutes after each automatic start.

This 10 minute run period can be loaded, unloaded or a
combination of the two and allows dissipation of heat
generated within the motor windings at start.

When the compressor has completed the settings of the
timer, the controller stops the compressor, turns on the
automatic restart light and displays AUTO-RESTART in the
message display.

Pressure sensor 4APT continues to monitor the package
discharge pressure and sends information to the controller
which automatically restarts the compressor when the
pressure falls to the online setting.

REMOTE LOAD/UNLOAD OPTION

This option allows the operator to remotely load and unload
the machine.

With the option enabled, two dierent switches can be wired
(refer to the electrical schematic for wiring locations). The
switches are customer supplied.

REMOTE START/STOP OPTION

The remote start/stop option allows the operator to control
the compressor from a remote mounted start/stop station.
This option may be selected from the customer set–up
routine.

With the option enabled, two dierent switches can be
wired to the Xe for remote start/stop. (Refer to the electrical
schematic for wiring locations.) The switches are customer
supplied and must be of momentary type. The stop switch
contacts are normally closed / the start switch contacts are
normally open.

The following notice must be permanently xed to the unit in
a prominent position.

(Factory tted on 60Hz machines).

WARNING

This machine is remote start and stop equipped.
Disconnect power before servicing.

May start or stop at any time.
Lock and tag out.

Can cause severe injury or death.
See Operators / Instruction Manual.

•

•

•

POWER OUTAGE RESTART OPTION

The Power Outage Restart option is for installations that
have interruptions in their incoming power supply to the
compressor and must maintain an uninterrupted supply
of compressed air. When turned on, the option allows the
compressor to automatically restart and load
10 seconds after incoming power is restored after a power
interruption. Suitable visible and audible warnings are given
before restart.

SEQUENCER CONTROL

Sequencer control capability can be added to the electronic
control system by utilising a sequencer interface. This option
is available as a eld installation kit.

TIMED LEAD/LAG OPTION

When two or more machines are set up in a Lead/Lag
situation. This option allows the machines to be switched
from Lead to Lag at certain time of day.

SCHEDULED START/STOP OPTION

Allows the machine to be started or stopped at certain times
of the day.

HIGH CONDENSATE LEVEL SWITCH

This option prevents high condensate levels in the inter­stage moisture separator, providing added protection against
condensate carryover into the second stage compression
module. If the condensate drain system becomes clogged
or inoperative, this switch would signal the controller to
shut the unit down and display a HIGH I/C CONDENSATE
trip. The option may be factory installed or ordered as a eld
installation kit.

RECEIPT / HANDLING

RECEIPT

Before signing the delivery receipt, inspect for damage and
missing parts. If damage or missing parts are apparent, make
the appropriate notation on the delivery receipt, then sign
the receipt. Immediately contact the carrier for an inspection.

All material shall be held in the receiving location for the
carrier’s inspection.

Delivery receipts that have been signed without a notation
of damage or missing parts are considered to be delivered
“clear.” Subsequent claims are then considered to be
concealed damage claims. Settle damage claims directly with
the transportation company.

If you discover damage after receiving the compressor
(concealed damage), the carrier shall be notied within
15 days of receipt and an inspection shall be requested
by telephone with conrmation in writing. On concealed
damage claims, the burden of establishing that the
compressor was damaged in transit reverts back to the
claimant.

Read the compressor nameplate to verify it is the model
ordered, and read the motor nameplate to verify it is
compatible with your electrical conditions.

Make sure electrical enclosures and components are
appropriate for the installation environment.

• UNPACKING AND HANDLING

The compressor will normally be delivered with a
polyethylene or other cover. If a knife has to be used to
remove this cover, ensure that the exterior paintwork of the
compressor is not damaged.

Incorporated within the base of the compressor are slots to
enable a fork lift truck to move the compressor. Ensure truck
forks are fully engaged on both sides. Alternatively a special
lifting frame can be used to enable a crane or hoist to move
the compressor. Use only marked lifting points.

Once the packaging and pallet are discarded and the
compressor is in its nal position, remove the yellow painted
transit brackets from the resilient mounts and store for future
use or discard.

IMPORTANT
Remove any shipping brackets particularly the soft

mount transit braces painted in yellow.

LONG TERM STORAGE

If the product will not be commissioned within six months of
receipt, it should be prepared for long term storage. Please
contact Ingersoll Rand for details.

where the atmosphere is as clean as possible is
recommended.

•

The area selected for the location of the compressor
should be free of dust, chemicals, metal lings, paint
fumes and overspray.

Hard surfaces may reect noise with an apparent
increase in the decibel level. When sound transmission
is important, a sheet of rubber or cork can be installed
beneath the compressor to reduce noise. Flexible piping
may be required.

See the general arrangement drawing for minimum
space requirements for normal operation and
maintenance.

Minimum space in front of the control panel door as
required by national or local codes shall be maintained.

Ambient temperatures higher than 46 °C (115 °F) shall be

•

CAUTION

A minimum of 1 m (3.3ft) all round the compressor is recommended. If headroom is restricted, then the exhaust
should be ducted or deected away from the machine.

Screw type compressors [1] should not be installed in air systems with reciprocating compressors without means of
isolation such as a common receiver tank. It is recommended that both types of compressor be piped to a common
receiver using individual air lines.

NOTICE

If ducting is tted, the sump breather needs to be piped outside the enclosure to avoid back pressure into the
compression module.

DISCHARGE AND CONDENSATE PIPING

It is essential when installing a new compressor [1], to review
the total air system. This is to ensure a safe and eective
total system. One item which should be considered is liquid
carryover. Installation of air dryers [3] is always good practice
since properly selected and installed they can reduce any
liquid carryover to zero.

To assure long trouble free operation of a compressor
operating with ON-LINE OFF-LINE control, the system volume
must be large enough to keep the load/unload cycles to a
minimum (greater than 2 minutes).

A receiver [2], installed before the feeder lines [5], may be
necessary to ensure that the total system volume is not less
than 2.0 U.S.Gallons per rated delivery C.F.M.

Discharge piping should be at least as large as the discharge
connection of the compressor. All piping and ttings should

•

be suitably rated for the discharge pressure.

It is important to install an isolation valve [7] within 3 feet (1
meter) of the compressor.

It is good practice to install line lters [4].

Include a means [6] to vent the discharge pipework
downstream from the machine’s check valve and upstream of
the rst system isolation valve [7].

When two rotary units are operated in parallel, provide an
isolation vaIve and drain trap for each compressor before the
common receiver.

The built−in intercooler and aftercooler reduce the discharge
air temperature below the dew point (for most ambient
conditions), therefore, considerable water vapor is condensed.
To remove this condensation, each compressor with built−in
aftercooler is furnished with two moisture separator/solenoid
valve combinations. Since these solenoid valves discharge

61115.10.33

80448574 Rev A 11

at dierent pressures, it is extremely important that they
are piped separately into an open drain.

A dripleg assembly and isolation valve should be mounted
near the compressor discharge. A drain line should be
connected to the condensate drain in the base.

IMPORTANT: The drain line must slope downward from the
base to work properly. For ease of inspection of the automatic
drain trap operation, the drain piping should include an open
funnel.

CAUTION

The use of plastic bowls on line lters and other plastic air line components without metal guards can be hazardous.
Their safety can be aected by either synthetic oils or the additives used in mineral oils. From a safety standpoint,
metal bowls should be used on any pressurized system.

NOTICE

Do not use the compressor to support the discharge pipe.

PRIOR TO STARTING

If the electric motor/control wiring should become exposed
or saturated with moisture/water deposits, it must be safely
dried o before attempting to make any part or conductor
electrically live.

Ensure all persons concerned are suitably competent with
electrical installations.

Ensure that there is a safe working procedure which has been
issued by supervisory personnel, and that it is understood by
all persons concerned with the operation of the compressor.

Ensure that the safety procedure to be applied is based on the
appropriate national regulations.

Ensure that the safety procedure is followed at all times.

ELECTRICAL CONNECTION

Feeder cables should be sized by a competent electrical
engineer to meet all power requirements.

IMPORTANT
Ensure that the control circuit is connected to the

transformer tapping that matches the supply voltage.

COOLING WATER PIPING

NOTICE

Water piping to and from the compressor package shall
be atleast as large as the package connection size. Do
not undersize the water piping.

Isolation valves with side drains should be installed on both
the inlet and outlet lines. To maintain cooler cleanliness and
reliability, it is important to install a strainer of 2 mm mesh
size on the inlet line. Strainers are available from

Ingersoll Rand.

•

•

•

The air compressor has a normally closed solenoid valve that
is tted to the water outlet side within the package. The valve
is wired into the air compressor control circuit and closes
when the compressor stops.

Carefully inspect the water system before installing the
air compressor package. Ensure that the piping is free of
scale and deposits that may restrict water ow to the air
compressor package. If water cleanliness is poor, ltration
installed on the water inlet pipe line is recommended.

Proper operation of the compressor requires that the cooling
water ow be provided at a maximum supply temperature of
46 °C (115 °F). See the compressor engineering data sheets for
cooling water ow rates.

Water temperature and pressure gauges should be installed
in the water piping for use in any fault nding of the water
system. Water pressure should ideally be between 3 and 5 bar
(43.5 and 72.5 psi) but shall not be above 10 bar (145 psi).

Water cleanliness is also extremely important. Cleaning of
coolers as a result of fouling is a customer responsibility.
Therefore, it is highly recommended that proper water
quality shall meet the requirements listed in WATER QUALITY
RECOMMENDATIONS later in this section.

VENTING THE WATER SYSTEM

At the initial installation, or for startup after draining the
water system, proceed to vent the system as follows:

Locate the water system vent cock on top of the
intercooler.

Open the water valve(s) allowing water to ow to the
package.

Open the vent cock and allow all air to escape from the
system. When water is observed at the vent cock, close it.

The system is now properly vented.

DRAINING THE WATER SYSTEM

Should it become necessary to completely drain the water
system, proceed as follows:

Disconnect the inlet and discharge water lines from the
connections located at the rear of the unit.

Locate the oil cooler by removing the left and centre rear
panels. Remove the two drain plugs located at the end of
the cooler.

Allow the system to completely drain.

WATER QUALITY RECOMMENDATIONS

Water quality is often overlooked when the cooling system
of a water-cooled air compressor is examined. Water quality
determines how eective the heat transfer rate, as well as the
ow rate will remain during the operation life of the unit. It
should be noted that the quality of water used in any cooling
system does not remain constant during the operation of
the system. The water make–up is eected by evaporation,
corrosion, chemical and temperature changes, aeration, scale
and biological formations. Most problems in a cooling system
show up rst in a reduction in the heat transfer rate, then in a
reduced ow rate and nally with damage to the system.

There are many constituents in the water system that must be
balanced to have a good, stable system. The following major
components should be monitored:

SCALE: Scale formation inhibits eective heat transfer, yet it
does help prevent corrosion. Therefore, a thin uniform coating
of calcium carbonate is desired in the inner surfaces. Perhaps
the largest contributor to scale formation is the precipitation
of calcium carbonate out of the water. This is dependent on
temperature and pH. The higher the pH value, the greater the
chance of scale formation. Scale can be controlled with water
treatment.

CORROSION: In contrast to scale formation is the problem of
corrosion. Chlorides cause problems because of their size and
conductivity. Low pH levels promote corrosion, as well as high
levels of dissolved oxygen.

FOULING: Biological and organic substances (slime) can also
cause problems, but in elevated temperature environments
such as cooling processes they are not a major concern.
If they create problems with clogging, commercial shock
treatments are available.

To ensure good operation life and performance of the
compressor cooling system, the recommended acceptable
ranges for dierent water constituents are included below:

Corrosivity (Hardness, pH, Total dissolved solids, Temperature
at inlet and Alkalinity should be analysed monthly, or if stable
for 3 to 4 months, analysed quarterly.

Acceptable concentration:
Langelier Index 0 to 1

•

•

Iron content should be analysed monthly.
Acceptable concentration:

Sulphate content should be analysed monthly.
Acceptable concentration:
50 mg/l (50 ppm)

Chloride content should be analysed monthly.
Acceptable concentration:
50 mg/l (50 ppm)

Nitrate content should be analysed monthly.
Acceptable concentration:
2 mg/l (2 ppm)

Silica content should be analysed monthly.
Acceptable concentration:
100 mg/l (100 ppm)

Dissolved Oxygen content should be analysed daily, or if
stable, analysed weekly.
Acceptable concentration:
0 mg/l (0 ppm) (as low as possible)

Oil and Grease content should be analysed monthly.
Acceptable concentration:
5 mg/l (5 ppm)

Ammonia content should be analysed monthly. Acceptable
concentration:
1 mg/l (1 ppm).

ROTATION CHECK

CAUTION

If the compressor is operated in the opposite direction
of rotation, airend damage may result and is not
warrantable.

Locate the rotation decal on each motor.

DRIVE MOTOR

The correct motor rotation is clockwise when viewed from the
rear or non–drive end of the motor.

For the compressor motor rotation check, the running of the
motor must be as short a time as possible.

After depressing the start button, IMMEDIATELY depress
the ”EMERGENCY STOP” BUTTON. Should the motor
rotation be incorrect, put the main isolator in the OFF
position.

Open the starter box door.

Interchange any two line connections (L1, L2 or L3) at the
starter. Close and fasten the starter box door. Recheck for
correct rotation.

•

•

INSTALLATION

61115.10.33

80448574 Rev A 13

FAN MOTOR

Observe the compressor cooling fan. The rotation should
be in accordance with the fan rotation decal axed to the
fan motor. Cooling air should exhaust from the top of the
compressor enclosure.

Should the motor rotation not be correct, put the main
isolator in the OFF position.

Interchange any two fan motor leads at the fan manual motor
starter (MMS). Close and fasten the starter box door. Recheck
for correct rotation.

CAUTION

Do not operate the machine with the panels removed
as this may cause overheating and operators to be
exposed to high noise levels.

Do not start or operate the machine in temperatures below
or approaching 0 °C (32 °F), because the operation of the
regulation system, the unloader valve, the safety valve, will be
compromised. Your Ingersoll Rand distributor will advise on
low ambient modications.

• ELECTRICAL DATA

An independent electrical isolator should be installed
adjacent to the compressor.

Feeder cables should be sized by the customer/electrical
contractor to ensure that the circuit is balanced and not
overloaded by other electrical equipment. The length of
wiring from a suitable electrical feed point is critical as voltage
drops may impair the performance of the compressor.

Feeder cable connections to studs L1–L2–L3 on isolator
should be tight and clean.

The applied voltage must be compatible with the motor and
compressor data plate ratings.

The control circuit transformer has dierent voltage tappings.
Ensure that these are set for the specic applied voltage prior
to starting.

CAUTION

Never test the insulation resistance of any part of
the machines electrical circuits, including the motor
without completely disconnecting the Xe controller.

OPERATING INSTRUCTIONS

BASIC OPERATION

NOTICE

The language and compressors of measure displayed on
the controller will be preset before leaving the factory.
If these are required to be changed, contact your local
Ingersoll Rand service provider.

PRIOR TO STARTING

Check that the lubricant level is at least visible in the center
of the sight glass and add lubricant if necessary. Refer to the
maintenance procedures for setting the correct level.

Ensure that the discharge air isolation valve is open. Switch
on the main electrical isolation switch. The control panel will
illuminate, indicating that the line and control voltages are
available.

INITIAL CHECK SEQUENCE

The controller will perform an initial check sequence if the
compressor receives initial power to the controller or has
experienced an trip reset. While the initial check sequence
occurs, the controller will display a “Checking Machine”
message.

During the initial check sequence, the controller will check
the control system for proper operation. During this time,
if any items are found inoperative, a trip will occur and the
compressor will not start.

After completion of the initial check sequence, the controller
will then display “READY TO START’. This process should be
completed within 10 seconds.

START SEQUENCE

The compressor will initially start by the operator pressing the
local start button or receiving a remote start command. The
compressor will start loaded at the end of star delta transition
period for a star delta starter or wait for a period of time equal
to the starter time set point for a remote starter.

STOP SEQUENCE

The compressor can be stopped by a local or remote
stop, a shutdown due to a trip, or an emergency stop.
All of the above conditions will cause the compressor to
stop immediately, except the local or remote stop. A local
or remote stop will open the blowdown valve and the
compressor will run for up to 10 seconds. The compressor
will stop if the system pressure reaches the oine pressure
setpoint. However, if the compressor stops for this reason,
it will automatically restart when the system pressure falls
below the online pressure set point.

NOTICE

If the compressor has to be stopped in an emergency
depress the emergency stop button located underneath
the instrument panel.

•

•

•

•

EMERGENCY STOPPING

If the compressor has to be stopped in an emergency
press the emergency stop button located underneath the
instrument panel.

This will over-ride the normal unload/stop button and will
immediately stop the compressor.

RESTARTING AFTER EMERGENCY STOPPING

If the compressor has been switched o because of a
compressor malfunction, identify and correct the fault before
attempting to restart.

If the compressor has been switched o for reasons of safety,
ensure that the compressor can be operated safely before
restarting.

Refer to the PRIOR TO STARTING and START SEQUENCE
instructions earlier in this section before restarting the
compressor.

compressor and the start sequence is being performed.
The time period for this state can vary depending on the
starter type of the machine.

Load Delay – The compressor is waiting for a small
period of time after starting before allowing the machine
to load. This ensures the machine is at operating
conditions before loading

Running Loaded – The compressor is operating and
producing air. The inlet valve is open and the blowo
valve is closed.

Running Unloaded – The compressor is operating,
but not producing air. The inlet valve is closed and the
blowo valve is open.

Auto-Restart – The compressor has stopped due to
pressure rising above the oine or auto-stop setpoints
and auto-restart being enabled. The compressor will
automatically restart when pressure falls to the online or
target pressure setpoint.

Stopping – The compressor has received a stop
command and the stop sequence is being performed.

Blowdown – The compressor must wait for a brief period
of time after stopping its motor before it is allowed to
start again.

Not Ready – The compressor has detected a condition
that will not allow the compressor to start. The condition
must be cleared before a start is allowed, but does not
need to be acknowledged.

Tripped – The compressor has detected an abnormal
operational condition that has stopped the machine. A
trip must be acknowledged by hitting the reset button
before the compressor can start.

Processor Init – The controller is being initialized.

can have multiple levels, depending on the service level
selection. A service level selection of 0 disables service
warnings.

Service Level 1

On-Screen Text: SVC Required

If service level 1 has been selected for the unit, a “SERVICE
REQUIRED” warning will be issued on hour intervals equal to
the service time period set point. This warning can be reset
the same as any other warning.

Service Level 2

On-Screen Text: 100 hours to Svc, SVC Required, Service Alarm

If service level 2 has been selected for the unit, the service
complete factory set point will be used to clear a level 2
service warning and reset the service time or date. The service
complete can be reset before a service warning occurs.

The initial “SERVICE REQUIRED” warning will occur at total
hour intervals equal to the service time period set point.
However, 100 hours before this a “100 HOURS TO SERVICE”
warning will occur. This warning can be reset the same as
any other warning. One hundred hours later the “SERVICE
REQUIRED” warning will occur. This warning can be reset
the same as any other warning, however this warning will

sequencing system is dened by the airbus address that is
set on the general settings folder. Also note that the pressure
signal used to determine when to load or unload another
compressor is based on the pressure reading from the
compressor at address 1 in the system.

Integral Sequencing – Enabling Integral Sequencing selects
this compressor to be the leader of the integral sequencing
system. It is important that only one compressor in the
sequence be selected as the lead compressor.

Unload Pressure – Determines the pressure at which a
compressor will be unloaded by the system.

Load Pressure – Determines the pressure at which a
compressor will be loaded by the system.

System Pressure – Shows the current pressure reading that
the system is using for control. This is typically compressor 1’s
package discharge pressure reading.

Start Delay Interval – Determines the amount of time
between loading compressors. This prevents all compressors
from loading at once.

Damping – The pressure control “Damping” setting which is
used to tune how quickly the system responds to pressure
deviations. The default is 10 and should not normally be
changed.

Tolerance – The pressure control “Tolerance” setting, which is
used to tell the system how to respond to changes in pressure
above and below the load/unload pressures. The default is 3.0
psi and should not normally be changed.

Number of Compressors – Denes how many compressors
are in the system. There is a maximum of 4.

Sequence – Displays the current load/unload order of the
system. Each compressor in the system is assigned a letter,
with “A” being the compressor to load rst and unload last,
and “D” being the compressor to load last and unload rst.

Priority – Each compressor can be assigned a priority
level. Compressors will only rotate positions with other
compressors of the same priority level.

Rotate Now – Selecting this setpoint will cause the sequence
to shift according to the priorities, regardless of the rotation
interval setpoint.

Rotation Interval – Determines the time period between
sequence rotations.

Time Left – Counts down the time until the sequence
rotation will occur.

8. Connect an Ethernet cable to your computer and to the controller. Within a minute, the computer will make a connection
to the controller. Once connected, you will be able to log into and congure the controller.

ETHERNET WIRES

Wiring the network is accomplished by connecting the user computer to the controller using Category 5 (or better) cables. The
connection point on the user computer is a RJ–45 port located on the Network Interface card.

The Ethernet cables are terminated with CAT 5 RJ–45 (RJ means “Registered Jack”) modular plugs. RJ–45 plugs are
similar to those seen on the end of a telephone cable except they have eight versus four or six contacts on the
end of the plug and they are about twice as big.

ETHERNET CONFIGURATION

The Ethernet conguration allows the user to select how the controller will be connected to the LAN.

The controller ships with a default IP address of 192.168.2.220. If “Enable DHCP” option is true in the “General Settings” [screen#
8] of the controller, then it will obtain an IP address via DHCP. Refer R55–160 kW Instruction manual for more information.

Once the user changes the “DHCP Enable” option to true, the “Assigned IP” address (e.g. 10.40.193.73) will appear below this
selection in few seconds. The users connected with the local area network can use this new assigned IP to login to the web
pages. Please note that depending on the LAN architecture, not all users will be able to view the web pages from their PC.

CAUTION

Changing the Ethernet conguration of the controller may cause the web pages to become unresponsive and require
IT or other support to return the web pages to an operational condition. Be certain all Ethernet settings are correct
before saving changes.

WARNING

Do not under any circumstances open any drain valve or
remove components from the compressor without rst
ensuring that the compressor is FULLY SHUT–DOWN,
power isolated and all air pressure relieved from the
system.

AIR FILTER CHANGE PROCEDURE

A warning message will appear if the air lter pressure drop
exceeds 0,048 bar (0,7 psi). To check the condition of the inlet
lter, run the compressor in load mode and select “INLET
VACUUM” from the current status screen using the up and
down arrows. Change if equal to or above 0,048 bar (0,7 psi).
To change the inlet lter, remove the appropriate enclosure
panel on the front of the machine.

Check the retaining cap for dirt and debris and wipe
clean.

Unclip the retaining cap and withdraw the old element.

Fit the new element and ret the retaining cap.

OIL CHANGE

To change the oil, the oil should be warm for more eective
drainage. Remove the right end enclosure panel. Remove
the pipe plug from the oil drain connection in the rear of
the baseplate. Place a suitable drain pan under the drain
connection and open the valve.

Dispose of waste lubricant according to local regulations.

When the gearcase is empty, close the valve and replace the
pipe plug. Change the oil lter and allow the oil to drain from
the oil cooler as well.

Unscrew the oil ller cap and add oil until the level reaches
the top of the gearcase sight glass.

Start the compressor and run in unload mode. Check the oil
lter and oil drain valve for leaks. Select ”BEARING OIL PRESS”
from the current status screen to insure that adequate oil
pressure has been attained. Inspect the gearcase sight glass,
the correct oil level for the sump during operation is 3/4 to
4/4 full. Some amount of foaming in the sight glass is normal.
The oil level is interpreted as the level in the sight glass
below the top foam, where a line of separation can be seen. If
additional oil is required, stop the compressor and add oil as
needed.

OIL FILTER

Change oil lter after every 8,000 hours or less as required
(see checking procedure below).To check the condition of
the oil lter, the compressor must be running and the oil
temperature must be greater than 49 °C (120 °F). With these
conditions met select ”OIL FILTER PRESS DROP” from current
status screen. If ”OIL FILTER PRESS DROP is less than 0,9 bar
(13 psi) then the oil lter does not need service. If the warning
light is on and ”CHANGE OIL FILTER” warning is displayed,
then the oil lter should be replaced.

Position the empty drain pan under the oil lter, loosen the
lter housing. Remove the element from the housing. Wipe
the sealing surface of the lter adaptor with a clean, lint–free
cloth. Remove the replacement lter from its protective
package. Apply a small amount of clean oil on the rubber seal
and install the element. Screw the element on until the seal
makes contact with the seat on the adaptor head. Tighten the
lter a further 1/2 to 3/4 of a turn.

Start the compressor, check for leaks and check the oil level.

GEARCASE BREATHER

To service the gearcase breather, remove the right end panel.
Remove the breather cover by unscrewing the four retaining
screws. Remove all of the breather media and clean with a
suitable solvent. Allow the media to dry. Re–install the media,
the cover, and the enclosure panel.

CONDENSATE DRAIN FUNCTIONALITY

To verify the functionality of the condensate drains, simply
observe the timed operation of each. Each drain should open
at least every 2 minutes while the compressor is loaded. (The
intercooler drain exhausts at a much lower pressure than the
aftercooler).

Oil free condensate can be disposed of via a sewer drain.

CONDENSATE STRAINERS

In order to service the condensate strainers (both inter-stage
and discharge), the strainer service valves preceding the
strainers should be closed. Remove the screens from the
strainers, while noting the direction. Clean any debris from
the screens and reinstall. Open the strainer service valves.

AIREND BEARINGS

Airend bearings are lubricated by the compressor lubricating
oil and require no maintenance.

COMPRESSOR MODULE INPUT SHAFT SEAL

REPLACEMENT

Remove the main motor, observing all safety precautions
in Section A of this manual, utilising appropriate lifting
gear as recommended and following established safe
