NOTICE

Items [2] to [5] are optional or may be existing items

of plant. Refer to your Ingersoll Rand distributor /

representative for specic recommendations.

LOCATION IN THE PLANT

The compressor can be installed on any level oor

capable of supporting it. A dry, well ventilated area where

the atmosphere is clean is recommended. A minimum of

150 mm (6 inches) should be left at the rear and 1 m

(3 ft) at the sides of the machine for adequate service

access and ventilation.

Adequate clearance needs to be allowed around and

above the machine to permit safe access for specied

maintenance tasks.

Ensure that the machine is positioned securely and on

a stable foundation. Any risk of movement should be

removed by suitable means, especially to avoid strain on

any rigid discharge piping.

NOTICE

The Main Motor Overload Current set point is preset

into the compressor controller program before

leaving the factory and is not user adjustable. If this

is required to be changed, due to an input voltage

conversion, contact your local Ingersoll Rand service

provider.



CAUTION

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.

CAUTION

The use of plastic bowls on line lters and other

plastic air line components can be hazardous. Their

safety can be aected by either synthetic coolants

or the additives used in mineral oils. Ingersoll Rand

recommends that only lters with metal bowls

should be used on any pressurised system.

CAUTION

Before starting machine remove shipping bolt and

discard.

CAUTION

The standard compressor unit is not suitable for

operation in temperatures liable to cause freezing

as condensate water is liable to be produced in the

after cooler and receiver where tted.

Refer to your Ingersoll Rand distributor for further

information.

DISCHARGE PIPING

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.

INSTALLATION / HANDLING

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 carry over to

zero.

It is good practice to locate an isolation valve close to the

compressor and to install line lters [4].

OPERATING INSTRUCTIONS

GENERAL OPERATION

The compressor is an electric motor driven, single stage

screw compressor, complete with accessories piped,

wired and baseplate mounted. It is a totally self contained

air compressor package.

The standard compressor is designed to operate in an

ambient range of 35.6 °F – 104 °F (2 °C to 40 °C) with a

special option package available to operate in ambient

temperatures ranges from 35.6 °F up to124 °F (2 °C up to

50 °C). The maximum temperature is applicable to either

version up to a maximum elevation of 3280 ft (1000 m)

above sea level. Above this altitude signicant reduction

in maximum allowable ambient temperature is required.

Compression in the screw type air compressor is created

by the meshing of two (male & female) helical rotors.

The air/coolant mixture discharges from the compressor

into the separation system. This system removes all but

a few PPM of the coolant from the discharge air. The

coolant is returned to the cooling system and the air

passes through the aftercooler and out of the compressor.

Cooling air is moved through the coolers by the cooling

fan and discharged from the machine.

CAUTION

Cooling air is drawn in at the end of the machine

package passing through the lter and cooler

before being discharged from the top of the

machine. Care should be taken to avoid blocking the

airow, or causing any restriction in excess of the

maximum backpressure allowed for ducting.

Do not direct the airow at face or eyes.

The power transmission from the drive motor to the

airend male rotor is by pulley and belts. The constant

auto tensioning system, using airend mass torque and

gas arm, ensures that the belts are always under the

correct tension, eliminating the need for adjustment and

maximizing the life of the belts.

 By cooling the discharge air, much of the water vapor

naturally contained in the air is condensed and may be

drained from the downstream piping and equipment.

The coolant system consists of a sump, cooler,

thermostatic valve and a lter. When the unit is operating,

the coolant is pressurized and forced to the compressor

bearings.The compressor load control system is

automatic on–o line.

The compressor will operate to maintain a set discharge

line pressure and is provided with an auto restart

system for use in plants where the air demand varies

suciently to allow a compressor to shut down and save

power. Signicant system volume will assist this and is

recommended.

NOTICE

Not all Xe-70 Controller options available on this

compressor model (UP Series).

WARNING

When the unit stops running as the result of low air

demand, normally indicated by auto restart light, it

may restart and return to load at any time.

Safety of operation is provided as the compressor will

shut down if excessive temperatures or electrical overload

conditions should occur.

CAUTION

This unit is not designed or intended to operate

when contaminated with silicone. Lubricants,

greases or other items containing silicone should

not be used on this unit.

DASHBOARD STATUS MESSAGES

The dashboard also displays the current operating

state of the compressor. The following states can be

encountered during machine operation:

Ready to Start – The compressor currently has no trip

or start inhibit conditions present. The machine can be

started by pressing the start button at any time.

Starting – A start command has been given to

the 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 blow-o

valve is closed.

Running Unloaded – The compressor is operating,

but not producing air. The inlet valve is closed and the

blow-o valve is open.

Reload Delay – This is a brief period of time after the

compressor has unloaded before it is allowed to load

again. This gives the inlet and bypass valves time to

reach their proper positions.

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. The compressor will restart at

the end of the blowdown period if a start command is

recieved during blowdown.

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.

machine.

Lead/Lag – When this box is checked the compressor is

operating as a lead machine. Unchecking the box causes

the machine to run as a lag machine.

Lag Oset – If the machine is running as a lag

compressor, the lag oset will be subtracted from the

online and oine setpoints.

Range (in PSI): 0 – 45, depending on the online and oine

setpoints. The Lag Oset will never allow you to exceed

the minimum or maximum values of the online and

oine setpoints.

Mode of Operation – Selections are Online/Oine,

Modulation/ACS, and Modulation only – determines how

the compressor will try to maintain a specic pressure.

Online/Oine – The compressor will load the

machine by energizing a solenoid that opens the inlet

valve and closes the blowdown valve when package

discharge pressure falls below the online pressure

setpoint. The compressor will unload the machine by

de-energizing the solenoid when pressure rises above

the oine pressure setpoint.

Modulation – The compressor will still load and

unload as in online/oine, but will energize a dierent

solenoid valve for modulation. When the package

discharge pressure is between the online and oine

setpoints the compressor will adjust the inlet valve in

order to achieve a stable output pressure. The output

pressure target needs to be set by a technician at the

inlet valve in order to provide eective modulation

control. Modulation can only work when the package

discharge pressure is above 60 psi. Modulation is an

option and must be enabled in the factory settings tab.

Mod/ACS – The compressor will initially start out in

online oine mode. If the compressor goes through 3

load/unload cycles within 3 minutes, it will switch over

into Modulation mode. It will remain in modulation

until the stop button is pressed or 3 minutes pass

between an unload and load command. Mod/ACS is an

option and must be enabled in the factory settings tab.

Unloaded Stop Time – Time period that the machine

must run unloaded before the motor is allowed to stop

after a stop command is received.

Range (in seconds): 10 - 30

Starter Time – Time period that the compressor needs

in order to come up to operating speed after a start

command before being able to produce air. Range (in

seconds): 5 - 30

The parameters on these pages are adjustable any time.

*Note that Mode of Operation can only be adjusted

if the modulation option has been purchased for the

compressor and the Enable Modulation factory setpoint

has been turned ON.

The below values are all setpoints

Enable Auto-Restart – Enabling this will allow the

compressor to stop if it has been running unloaded for a

period of time, and the motor has exceeded its minimum

running time (10 minute in most cases).

Auto-Restart Time – The time period the compressor

must run unloaded before stopping in auto-restart. This

time period begins the moment that package discharge

pressure rises above the oine setpoint. Both this time

period and the minimum motor run timer (10 minutes)

must be satised before the compressor will stop in auto

restart.

Range (in seconds) 2 - 60

Auto-Restart Delay – The time period after the package

discharge pressure has fallen below the online setpoint

before the compressor can automatically restart.

Range (in seconds): 0 - 60

COM Control – Enabling this setpoint allows the

compressor to be controlled by a serial or Ethernet device,

such as an X8I. This is equivalent to the “Sequencer”

option on older Intellisys controllers.

Remote Start/Stop – Enabling this setpoint allows the

compressor to be started and stopped using the digital

inputs on the controller.

Enable PORO – Enabling this setpoint will allow the

compressor to automatically restart after a power outage

has been restored if the compressor was running loaded

at the time of the outage. PORO is an option which must

be purchased and installed before this feature can be

turned ON.

PORO Time – Time after the controller power has been

restored and controller has nished booting before the

compressor will perform a PORO start. During this time

the PORO Horn will sound.

Range (in seconds): 10 - 600

Low Ambient Temp – Temperature below which the low

ambient option will come into eect.

Range (in deg F): 30 - 60

Scheduled Start Day – Day (or days) of the week

for which a scheduled start will be performed. The

compressor will start when its onboard clock matches the

day, hour, and minute of the scheduled start setpoints.

Scheduled Start/Stop is an option which must be

purchased and installed before this feature can be turned

ON.

Scheduled Start Hour – Hour of the day for which a

scheduled start will be performed. Scheduled Start/Stop

is an option which must be purchased and installed

before this feature can be turned ON.

Scheduled Start Minute – Minute of the hour for which

a scheduled start will be performed. Scheduled Start/

Stop is an option which must be purchased and installed

before this feature can be turned ON.

Scheduled Stop Day – Day (or days) of the week

for which a scheduled stop will be performed. The

compressor will stop when its onboard clock matches the

day, hour, and minute of the scheduled stop setpoints.

Scheduled Start/Stop is an option which must be

purchased and installed before this feature can be turned

ON.

Scheduled Stop Hour – Hour of the day for which a

scheduled stop will be performed. Scheduled Start/Stop

is an option which must be purchased and installed

before this feature can be turned ON.

Scheduled Stop Minute – Minute of the hour for which

a scheduled stop will be performed. Scheduled Start/

Stop is an option which must be purchased and installed

before this feature can be turned ON.

Note that in order to disable Scheduled Start/Stop, the

Scheduled Start and Stop days, hours, and minutes must

match exactly.

* The low ambient temperature is only adjustable if the

low ambient factory set point is ON.

** A value of 0 will disable the lead/lag cycle time feature.

Page 7 Calibrate Sensors

Figure 10 : Calibrate Sensors

Sensor calibration can only take place when the machine

is stopped and there is no pressure on the sensor.

Calibration only needs to take place after a sensor

is replaced, the controller is replaced, the controller

software is upgraded, or the operator suspects the

sensor reading is in error. Calibrate a sensor by selecting

the checkbox beside the sensor name. Note that

the checkbox may appear too quickly to be visible.

Calibration can be conrmed by verifying that the sensor

value now reads zero.

Each of the sensors listed below can be calibrated.

Sump Pressure (3APT) – Only on units with the Enable

3APT factory setpoint ON.

Package Discharge Pressure (4APT)

After-cooler Discharge Pressure (7APT) – Only on units

with integrated dryer. Note : Not available on this

compressor model.

Note that if a sensor is currently reading a value that is +/-

10% of its range from zero, the sensor will not be able to

be calibrated and an warning will be logged in the event

log. Make sure the sensor is being exposed to atmosphere

before attempting calibration.

If the unit is running loaded, has been loaded for at least 8

seconds and the sump pressure is more than 25 psi above

the rated pressure for the compressor. If this warning

occurs, the online and oine pressures will be reduced.

For example, a rated pressure of 100 psi would have a

maximum oine pressure of 110 psi. This warning would

occur if the sump pressure goes above 125 psi in this

example. This condition must exist for 3 seconds before

the warning is issued.

Note that the Enable 3APT setpoint must be turned ON

Service

Service warnings occur when the unit has operated

a certain number of hours, based on the total hours.

Service warnings can have multiple levels, depending on

the service level selection. A service level selection of 0

disables service warnings.

Service Level 1

Xe-70M 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

Xe-70M 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 return in 24 hours if the service complete factory set

point has not be set. If the service complete has not been

set, 100 hours later, the “ALARM – SERVICE REQUIRED”

warning will be issued. This warning can only be cleared

by the service complete factory set point. Once the

service complete factory set point is set, indicating the

service is completed, the time for the next “SERVICE

REQUIRED” warning will be calculated by adding the

service time period to the total hours value, with the “100

HOURS TO SERVICE” warning occurring 100 hours before

and the “ALARM – SERVICE REQUIRED” warning occurring

100 hours after that time.

High Discharge Pressure

Xe-70M On-Screen Text: High Disch Pres

Will occur if the unit is using a remote sensor or is under

the control of an external device, such as an X8I, is loaded,

and the discharge pressure (4APT) is greater than the

maximum oine pressure. This condition must exist for

3 seconds before the warning is issued. If this condition

occurs, the compressor will automatically unload. The unit

will be available to reload once the discharge pressure

falls to the rated pressure value.

This will occur if 2ATT is greater than 228 deg F and the

unit is running.

Check Motor Rotation

Xe-70M On-Screen Text: Ck Motor Rot

This will occur if 3APT is less than 1 psi on a unit, 3

seconds after starting (6 seconds if the unit is equipped

with a soft starter or airend discharge temperature is

less than 50 deg F). This condition can be caused by the

motor running in reverse. Once correct motor rotation

is established, this trip will not be checked again unless

power is removed from the controller. However, if correct

motor rotation is not established, this fault will be

checked after each start until correct motor rotation is

established. Correct motor rotation is established when

the controller reads a sump pressure of 1 psi or more

within 3 seconds of starting.

Note that the Enable 3APT setpoint must be turned ON

for this warning to occur.

Overload

Xe-70M On-Screen Text: Overload

This will occur if the fan or motor overload relays opens.

OPERATING INSTRUCTIONS XE70M CONTROLLER

INTEGRAL SEQUENCING FOLDER

Figure 22 : Integral Sequencing folder

Integral Sequencing allows the compressor to be

networked with up to three other compressors (xed or

variable speed) to maintain a stable system pressure by

loading and unloading compressors as needed. Integral

sequencing requires no additional hardware other than

a serial two wire connection daisy chained between all

compressors in the system, connected to port X04 on the

controller.

For a compressor to be a member of the integral

sequencing system, the COM control setpoint in

the operator settings tab must be enabled and the

compressor must be started via the local start button.

Additionally, it is recommended that the Auto-Restart

function be enabled as the integral sequencing system



OPERATING INSTRUCTIONS XE70M CONTROLLER

RELEASED 20/Jul/2016 17:56:55 GMT

will never start and stop machines, only load and unload

them. Integral sequencing relies on Auto-Restart to turn

OFF the compressor motor when not needed.

Please note that the compressor’s address in the integral

sequencing system is dened by the RS-485 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 assigned as the integral sequencing

master. Lastly, note that the Active Protocol on the

general settings tab must be set to Airbus485 for integral

sequencing to operate properly.

Certain functions may interfere with compressors loading

and unloading:

Verify that the Remote Load Enable switch is in the

open position. Having this closed will allow the remote

load/unload switch to dene the load command.

Start Delay Interval – Determines the amount of

time between loading compressors. This prevents all

compressors from loading at once. This setpoint should

be set to the longest starting time of any compressor in

the system. In general, this will be equivalent to the star/

delta transition time for a xed speed machine, or ramp

time for a VSD machine.

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.

Priority – Each compressor can be assigned a priority

level. Setting a priority for a compressor aects how

the rotation will occur. Compressors with priority 1 will

always be in the lead position(s), followed by priority 2

compressors, and so on. Compressors will only rotate

positions with other compressors of the same priority

level.

•

Sequence – Displays the current load/unload order of

the system. Each compressor in the system is assigned

a letter. The letter indicates whether the machine with

the assigned Airbus address is a lead machine (loads

rst, unloads last) or one of the trim machines. Letter A

is assigned to the lead machine, B to the next machine

to load, C to the third machine to load, and D to the nal

machine to load. Machines will unload in the reverse

order, such that A will be the last machine running.

The rst position in the - - - - sequence on Integral

Sequencing tab, page 3 always refers to the compressor

that is assigned Airbus Address 1. The second position to

Airbus Address 2, and so on. Note that the letter sequence

may change due to rotation.

Note that the sequence will only be displayed on the

master controller.

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

automatic sequence rotations.

Time Left – Counts down the time until the sequence

rotation will occur.

System Pressure – Shows the current pressure reading

that the system is using for control. This will only be

shown on the sequence Master controller.
