Electricity and compressed air have the potential to cause severe personal injury or property damage.

Before installing, wiring, starting, operating or making any adjustments, identify the components of the air compressor using this manual as a guide.

The operator should use common sense and good working practices while operating and maintaining this unit. Follow all codes, pipe adequately, understand the starting and stopping sequence. Check the safety devices by following the procedure contained in this manual.

Maintenance should be done by qualified personnel, adequately equipped with proper tools. Follow the maintenance schedules as outlined in the operators manual to ensure problem free operation after start up.

0.2 SAFETY PRECAUTIONS

Safety instructions in the operators manual are bold-faced for emphasis. The signal words DANGER, WARNING and CAUTION are used to indicate hazard seriousness levels as follows:

Danger is used to indicate the presence of

D! DANGER a hazard which will cause severe personal injury, death, or substantial property

damage if the warning is ignored.

Warning is used to indicate the presence of

! WARNING a hazard which can cause severe personal injury, death, or substantial property

damage if the warning is ignored.

Caution is used to indicate the presence of

! CAUTION a hazard which will or can cause minor personal injury or property damage if the

warning is ignored.

Notice is used to notify people of NOTICE installation, operation, or maintenance information which is important but not

hazard-related.

SAFETY PRECAUTIONS

BEFORE PROCEEDING, READ CAREFULLY BEFORE INSTALLING THE COMPRESSOR OR PERFORMING ANY MAINTENANCE

WARNING

COMPRESSED AIR AND ELECTRICITY ARE DANGEROUS.

BEFORE DOING ANY WORK ON THIS UNIT, BE SURE THE ELECTRICAL SUPPLY HAS BEEN CUT OFF–LOCKED & TAGGED AND THE ENTIRE COMPRESSOR SYSTEM HAS BEEN VENTED OF ALL PRESSURE.

1. Do not remove the covers, loosen or remove any fittings, connections or devices when this unit is in operation. Hot liquid and air under pressure that are contained within this unit can cause severe injury or death.

2. The compressor has high and dangerous voltage in the motor starter and control box. All installations must be in accordance with recognized electrical codes. Before working on the electrical system, be sure to remove voltage from the system by use of a manual- disconnect-switch. A circuit breaker or fuse safety switch must be provided in the electrical supply line leading to the compressor.

Those responsible for installation of this equipment must provide suitable grounds, maintenance clearance and lightning arrestors for all electrical components as stipulated in O.S.H.A. 1910.308 through 1910.329.

3.Do not operate the compressor at higher discharge pressure than those specified on the Compressor Nameplate or motor overload will occur. This condition will result in compressor motor shutdown.

4.Use only safety solvent for cleaning the compressor and auxiliary equipment.

5.Install a manual shut off valve (isolation type) in the discharge line. When a safety valve is installed between the isolation valve and the compressor, it must have sufficient capacity to relieve the full capacity of the compressor(s).

6.Whenever pressure is released through the pressure relief valve, it is due to excessive pressure in the system. The cause for the excessive pressure should be investigated immediately.

7.Before doing any mechanical work on the compressor:

a.) Shut the unit down.

b.) Electrically isolate the compressor by use of the manual disconnect switch in the power line to the unit. Lock and tag the switch so that it cannot be operated.

c.) Vent pressure from the compressor and isolate the unit from any other source of air.

8. There can be adverse effects if compressor lubricants are allowed to enter plant air systems.

Air line separators, properly selected and installed, will minimize any liquid carryover.

The use of plastic bowls on line filters without metal guards can be hazardous. From a safety standpoint, metal bowls should be used on any pressurized system. Review of your plant air line system is recommended.

9.When a receiver is installed, it is recommended that occupational safety and health standards as covered in the Federal Register, Volume 36, number 105, part 11, paragraph 1910.169 be adhered to in the installation and maintenance of this receiver.

10.Before starting the compressor, its maintenance instructions should be thoroughly read and understood.

11.After maintenance functions are completed, covers and guards must be replaced.

3

SAFETY SHUTDOWN

CHECK HIGH AIR TEMPERATURE

There is a high discharge air temperature shutdown function built into the Intellisys on each compressor. It is factory pre-set at 228°F (109°C). This function should be checked at regular intervals for proper operation, once a month is recommended. The procedure is:

1.Block off the cooling air discharge.

2.The compressor discharge temperature will rise at a rapid rate. Shutdown should occur when the discharge temperature reaches the pre-set maximum discharge air temperature setting of the Intellisys. The display should indicate “HIGH AIREND DISCH TEMP” and flash “ALARM”.

The actual temperature at which shutdown occurs should be recorded for comparison to the Intellisys set point and with similar future test results.

WARNING

Failure to adhere to these recommendations can result in mechanical failure, property damage and serious injury or death.

All air and water inlet, and air and water discharge pipework to and from the inlet and discharge port connections must take into account vibration, pulsations, temperature, maximum pressure applied, corrosion and chemical resistance. In addition, it should be noted that lubricated compressors will discharge some oil into the air stream; therefore, compatibility between discharge piping, system accessories and software must be assured.

For the foregoing reasons, the use of plastic piping, soldered copper fittings and rubber hose as discharge piping is not recommended. In addition, flexible joints and/or flex lines can only be considered for such purposes if their specifications fit the operating parameters of the system.

It is the responsibility of the installer and owner to provide the appropriate service pipework to and from the machine.

WARNING

“Ingersoll-Rand air compressors are not designed, intended, or approved for breathing air. Ingersoll-Rand does not approve specialized equipment for breathing air application and assumes no responsibility or liability for compressors used for breathing air services.”

2.0INSTALLATION

2.1VENTILATION

Oil flooded rotary air compressors produce large amounts of heat. Because of this large heat production, the compressor must be placed in a room with adequate ventilation.

If heated air from the compressor exhaust is allowed to recirculate back to the compressor, the compressor will overheat and shut down. This heat must be exhausted from the room. You should take this into consideration when you decide where to place the compressor within your plant. Consider that the required maintenance clearance is 3 ft (.9 m) all around the compressor. However 42” (1.06m), or minimum required by latest NEC or applicable local codes, must be maintained in front of control panel.

Ambient temperatures higher than 115°F (46°C) should be avoided as well as areas of high humidity.

Consider also the environment surrounding or near the compressor. The area selected for the location of the compressor should be free of dust, chemicals, metal filings, paint fumes and overspray.

2.2 FOUNDATION REQUIREMENTS

Refer to the foundation plan for the particular model compressor to be installed. See Section 8.0.

The compressor can be installed on any level floor that is capable of supporting it. Compressor weights are listed on the foundation plans.

When sound transmission is of particular importance it is often helpful to install a sheet of rubber-fabric-matting, or cork under the compressor to reduce the possibility of resonant sounds being transmitted or amplified through the floor.

NOTICE

Never elevate the compressor unit above the floor level. This may allow air to enter the cabinet under the base. Performance will be affected.

2.3 PIPING

The use of plastic bowls on line filters without metal guards can be hazardous. Their safety can be affected by either synthetic lubricants or the additives used in mineral oil. From a safety standpoint, metal bowls should be used on any pressurized system. Review of your plant air line system is recommended.

WARNING

Do not use plastic pipe, soldered copper fittings or rubber hose for discharge piping.

The built-in aftercooler reduces the discharge air temperature well 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 a combination condensate separator/trap.

9

2.3 PIPING (Continued)

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.

NOTE: For ease of inspection of the automatic drain trap operation, the drain piping should include an open funnel.

It is possible that additional condensation can occur if the downstream piping cools the air even further and low points in the piping systems should be provided with driplegs and traps.

IMPORTANT: Discharge piping should be at least as large as the discharge connection at the compressor enclosure. All piping and fittings must be suitable for the maximum operating temperature of the unit and, at a minimum, rated for the same pressure as the compressor sump tank.

NOTICE

Do not use the compressor to support the discharge pipe.

Careful review of piping size from the compressor connection point is essential. Length of pipe, size of pipe, number and type of fittings and valves must be considered for optimum efficiency of your compressor.

It is essential when installing a new compressor to review the total plant air system. This is to ensure a safe and effective total system.

Liquid water occurs naturally in air lines as a result of compression. Moisture vapor in ambient air is concentrated when pressurized and condenses when cooled in downstream air piping.

Moisture in compressed air is responsible for costly problems in almost every application that relies on compressed air. Some common problems caused by moisture are rusting and scaling in pipelines, clogging of instruments, sticking of control valves, and freezing of outdoor compressed air lines. Any of these could result in partial or total plant shutdown.

Compressed air dryers reduce the water vapor concentration and prevent liquid water formation in compressed air lines. Dryers are a necessary companion to filters, aftercoolers, and automatic drains for improving the productivity of compressed air systems.

MOISTURE CONTENT OF COMPRESSED AIR

10

Two types of dryers, refrigerated or desiccant, are used to correct moisture related problems in a compressed air system. Refrigerated dryers are normally specified where compressed air pressure dew points of 33°F (1°C) to 39°F (4°C) are adequate. Desiccant dryers are required where pressure dew points must be below 33°F (1°C).

Contact your local Ingersoll-Rand distributor for assistance in selecting correct Ingersoll-Rand filtration or drying products.

NOTE: Screw type compressors should not be installed in air systems with reciprocating compressors without a means of pulsation isolation, such as a common receiver tank. We recommend both types of compressor units be piped to a common receiver utilizing individual air lines.

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

2.4 ELECTRICAL INSTALLATION

Before proceeding further, we recommend that you review the safety data in the front of this manual.

Locate the compressor data plate on the side of the cooler box or end of the unit.

The data plate lists the rated operating pressure, the maximum discharge pressure and the electric motor characteristics and power.

Confirm that the line voltage and compressor nameplate voltage are the same and that the standard starter box meets the intent of NEMA 1 guidelines.

Open the starter box door. Confirm that all electrical connections are made and tightened. Confirm that the control transformer is wired correctly for supply voltage. See Figure 2.4-1 on next page for typical control transformer wiring.

FAN MOTOR

Observe the compressor cooling fan. The rotation should be in accordance with the fan rotation decal affixed to the fan motor. Cooling air should exhaust through fan end of compressor enclosure.

Should the motor rotation not be correct, put the main disconnect in the OFF position, lock and tag.

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

Fan motor rotation is clockwise when viewed from the fan motor side.

INTELLISYS OPERATING INSTRUCTIONS

Read and understand the following Intellisys Operating Instructions (See Figure 2.4-4) prior to operating the unit.

NOTE: These instructions are also contained on the decal near the Intellisys panel of the unit.

2.5 OUTDOOR SHELTERED INSTALLATION

Many times a compressor must be installed outside due to jobsite conditions or limited space within a manufacturing facility. When this occurs there are certain items that should be incorporated into the installation to help ensure trouble free operation. These items have been listed below plus Figure 2.5-1 has been included to show a typical outdoor sheltered installation. The unit must be purchased with the Outdoor Modification Option to provide NEMA 4 electrics and a cabinet exhaust on the end of the unit rather than the top to prevent recirculation of cooling air.

The compressor should be on a concrete pad designed to drain water away. If the concrete pad is sloped, then the compressor must be leveled. In order to properly pull cooling air through the aftercooler, the base/skid must be sealed to the concrete pad.

The roof of the shelter should extend a minimum of 4 ft (1.2 m) around all sides of the compressor to prevent direct rain and snow from falling on the unit.

Air-cooled machines must be arranged under the shelter in a way that prevents air recirculation (i.e. hot exhaust back to the package inlet).

If the installation includes more than one compressor, the hot air exhaust should not be directed towards the fresh air intake of the second unit or an Air Dryer.

If a standard machine is to be installed outside, the ambient temperature must never drop below 35°F (1.7°C).

If ambient temperature drops below 35°F (1.7°C) to as low as –10°F (–23°C) the unit must be supplied with the Low Ambient Option. Installations below –10°F (–23°C) ambient are not recommended. The Low Ambient Option requires a separate power source to operate internal heaters.

Arrange the machine with the Intellisys controller/starter enclosure facing away from the sun as radiant heat can affect starter/lntellisys performance. Also direct sunlight and UV rays will degrade the membrane touch panel. This is not a warrantable situation.

Power disconnect switch should be within line of sight and in close proximity to the unit. N.E.C. and local electrical codes must be followed when installing the power disconnect switch.

Condensate drains must never be allowed to dump on the ground. Run to a suitable sump for future collection and disposal or separation of lubricant and water mixture.

Incoming power connections must use suitable connectors for outdoor weather tight service.

A minimum of 3 ft (.9 m) clearance must be allowed on all four sides of the unit for service access. If possible, access by a forklift and/or an overhead beam hoist should be kept in mind (for eventual service to airend or motor).

If the area around the installation contains fine airborne dust or lint and fibers etc., then the unit should be purchased with the High Dust Filter Option and TEFC motors.

If larger debris, such as leaves or trash, are blowing in the area, the Inlet Panel Filter Accessory should be purchased and added to the unit (ship loose item).

Some type of protection such as a fence or security system, should be provided to prevent unauthorized access.

Pressing this switch stops the compressor immediately. The compressor can not be restarted until the switch is manually reset. Turn the switch knob clockwise to reset.

EMEG

STOP

POWER ON LIGHT

This indicates the control voltage and the line voltage are available for starting.

POWER

ON

The operator panel is divided into two areas. The bottom row of four buttons provides direct control over the starting, stopping, unloading and loading of the compressor. These are defined by the symbols printed on the buttons themselves, as shown here.

START

Pressing this button will start the compressor if the display shows “Ready To Start”. The compressor will start and load if there is sufficient demand for air.

STOP

Pressing this button will activate the unloaded stop sequence. If the compressor is running loaded, it will unload and continue to run unloaded for an adjustable 10 to 30 seconds and then stop. If the compressor is running unloaded, it will stop immediately.

UNLOAD

Pressing this button will cause the compressor to unload and remain unloaded. The display will indicate the machine is “Running Unloaded”, and “Mode: UNLOAD”.

LOAD

Pressing this button will cause the compressor to load if the compressor is running and if the “Discharge Pressure” is less than the “Online Pressure”. This also returns the machine to the operating mode that is specified by the “Mode of Operation” set point.

The other five buttons provide access to various operator-selectable functions and machine operating conditions. The purpose of each of these buttons is defined by the display screen and the particular function being performed at that time.

ARROWS

These up and down buttons have multiple functions relating to the right half of the display screen. When lists are presented, the buttons are used to move up or down through the items on the list. The small arrow(s) displayed in the upper right corner of the display screen indicate when you can move up (designated by arrow head pointing up) and/or down (designated by arrow head pointing down) through the list.

When the value of a specific machine operating parameter is highlighted on the display screen for the purpose of changing that value, the buttons are used to change the value itself.

DISPLAY BUTTONS

The functions of the three buttons below the display screen change and are defined by the words immediately above them in the bottom line of the screen. Each function, such as MAIN MENU, STATUS, SET, etc., is described in appropriate sections in this manual.

MAIN MENU

The display screen is divided into three functional areas, as seen in the typical CURRENT STATUS screen shown here.

The left side continuously shows the package discharge pressure in large numbers, with the line directly below the numbers showing the running condition of the machine, and the line below that showing the present mode of operation.

The right side shows various items or lists such as the machine’s CURRENT STATUS readings, the MAIN MENU, the OPERATOR SETPOINTS list, etc. Any of the lists can be moved up or down by pressing the arrow buttons to the right of the screen. The small arrow(s) displayed in the upper right corner of the screen indicate when you can move up (designated by

arrow head pointing up) and/or down (designated by arrow head pointing down) through a list. The arrow buttons are also used to change an individual item’s value. At certain times, items and/or their values are “highlighted”. This means they are displayed as light characters on a dark background.

The bottom of the screen is divided into thirds with the words in each small box showing the function of the button directly beneath it. The words will change in these boxes depending on what actions are permitted at any particular time. The action resulting from pressing each of these buttons is indicated in Figure 3.2.1, which can be used as a quick reference of how to step the controller screen through any desired function.

Setpoints associated with options are described in the OPTIONS Section 3.6.

A setpoint’s value can be changed by first highlighting the item and its value and pressing the SELECT button to highlight just the value. When the value line is highlighted by itself, the value can be adjusted using the up and down arrow buttons. The CANCEL and SET buttons appear at this time. Press the SET button to enter the new value, or press the CANCEL button to return to the value of the setpoint prior to using the arrows. The displayed value will flash twice to indicate it has been entered into the setpoint, and the pair of setpoint item and value display lines will again be highlighted together.

Operator set points can be exited by pressing the STATUS or MAIN MENU buttons. If no buttons are pressed within 30 seconds, the display will return to the CURRENT STATUS screen.

3.5.1Lead/Lag- This setpoint is used for setting lead or lag operation. If set to lead, the controller will load and unload the compressor by the online and offline setpoints. If set to lag, the controller will subtract the lag offset (see 3.5.4) from the online and offline set points and operate the compressor at the lower pressure range.

3.5.2Offline Pressure- This setpoint is the pressure the compressor will unload at if it is operating in on/off line mode.

3.5.3Online Pressure- This setpoint is the pressure the compressor will load at.

3.5.4Lag Offset- This setpoint is used with the lead/lag operation. If the lead/lag set point is set to lag (see 3.5.1), the value of the lag offset will be subtracted from the online and offline setpoints.

3.5.5Mode of Operation- This setpoint is used to select the operating mode of the compressor. The choices are MOD/ACS, ON/OFF LINE, and MODULATION ONLY. See section 5.8 for more information on these operating modes.

3.5.6Max Modulation Pressure- This setpoint is the pressure the compressor will unload at if it is modulating. As the package discharge pressure rises toward this value, the inlet valve will start to close. The compressor will unload once the package discharge reaches this value. See section 5.8 for more information on modulation.

3.5.7Stop Delay Time- This setpoint is the minimum amount of time the compressor will run unloaded before stopping. This period does not apply to alarms (shutdowns).

3.5.8Star-Delta Time- This setpoint is only used with star-delta starters. It is not used if the starter is full voltage or a remote starter. This is the time period between starting and star-delta transition.

3.5.9Contrast- This setpoint is used to improve the display on the Intellisys.

Integral Sequencing is set up using the INTEGRAL SEQUENCING screen. A description of integral is in section 7.0. The name and value of each of the integral sequencing setpoints as listed in the right hand column can be seen by moving the list up and down using the arrow buttons.

3.10.1Lead Compressor- The choices for this setpoint are On, Off, Always, and Never. On, means the compressor is the lead unit. Off, means the compressor is not the lead unit, but it could become the lead unit. If Always is selected, the compressor is the lead unit and it will not transfer the lead to another compressor. Never, means the compressor is not the lead unit and will never become the lead unit. The operator must set one unit (and only one) to On or Always to start integral sequencing.

3.10.2Total Compressors- This is the total number of compressors in the integral sequence. This setpoint must be set to the same number on each compressor.

3.10.3Compressor Address- This is the address of the compressor in the integral sequence. No two compressors can have the same address. Two compressors with the same address will cause communication failures.

3.10.4Load Delay Time- This is the number of seconds the lead compressor will wait for the package discharge pressure to start rising after issuing a load command to another compressor. If the package discharge pressure has not started rising at the end of this time period, the lead compressor will load the next compressor in the sequencer.

3.10.5Lead Change - Hours- This is the number of hours the compressor will operate as the lead unit. Once a compressor has operated as the lead for this number of hours, it will transfer the lead to the next compressor in the sequence. This setpoint does not apply to a unit where the lead compressor is set to always or never. If this setpoint is set to 0, the next 2 setpoints will determine when the lead is transferred.

3.10.6Lead Change - Day & Lead Change - Time-

These two setpoints are used together. If the Lead Change - Hours setpoint is set to 0, these two setpoints will be used to determine when the compressor will transfer the lead to the next compressor in sequence. Lead Change - Day is the day of the week that the compressor will transfer the lead. Lead Change - Time is the time of the day that the compressor will transfer the lead.

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.

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.
