display graphic screens, which represent various aspects
of compressor operation. By pressing a key on the keypad, the labeled or described function is recognized by the
control processor, and appropriate action is taken.
Each individual Compressor unit is controlled by a computer based machine control system, known as the Quantum™ LX control panel. This controller continuously monitors the conditions and operation of the compressor unit
and the various subsystems. It also directs the operation
of components. It is fully self-contained.
Although the primary means of operator interaction to
the compressor package is via the built-in Quantum™
LX control panel, there are two additional methods that
emulate the graphic control screens that may be used
remotely for compressor control. The following information is presented to help the operator interact with these
graphic screens.
The Quantum™ LX control panel user interface is used to
QUANTUM™ LX CONTROL PANEL
The Quantum™ LX control panel contains all of the necessary control hardware and software within one self
contained enclosure, and is mounted to the compressor
package. The front of this control enclosure contains a
graphic display and keypad to allow the operator to access essential information and to make necessary adjustments to setpoints, calibrations and features.
operating characteristics. For easier viewing, related information is separated into boxes. Sometimes selections
are hidden when that the feature is unavailable.
Operator access to this system is through various screens.
A screen is the physical representation of data on the display. Each screen has a title area and is descriptive of
the screen. The current date and time is shown in this
title area. The day of the week, Sunday (Sun.) through
Saturday (Sat.) is displayed. The month of the year from
January (Jan.) to December (Dec.) is displayed. The day of
the month from 1 to 31 and the year from 0001 to 9999
is displayed. The time displayed is the current time in 24
hours (military) format. The hours, minutes and seconds
are displayed.
Some screens are for informational purposes only, and
cannot be modified. These screens typically show analog values such as temperatures, pressures and humidity,
which are strictly functions of an associated sensor, and
as such, cannot be modified. Other screens show setpoint
values which can be changed, in order to modify the units

IP Address.
At the computer, open the Internet browser (click on your
Internet icon). Once the browser has opened, look for the
address bar, it will appear similar to the following:
On the address bar, type the following [ http:// ]. Do not
type the brackets. After the http:// type in the values of
the four boxes from IP Address of the Ethernet Configuration screen. Place a period (dot) between each group
of numbers. Using the screen information example used
here, the result would be http://192.168.0.252. Your particular IP Address may vary from the example shown.
All Interface screens will have several buttons on the right
hand side of the screen:
[Menu] – Clicking on this button will cause the main
menu to appear on the left side of the screen. Clicking a second time will cause the menu to disappear.
[Submit] – Although this button does not appear
in the example above, it will be present on most

when a warning is present. A warning is a condition that requires operator acknowledgement
but allows the compressor to continue to run if it
is already running.
Recycle Delay - This message shows the
remaining time in minutes for Recycle Delay. If the compressor has started and shuts
down within the recycle time delay setpoint
period, the Recycle Delay will prevent the
compressor from starting until the delay
time expires. This time delay is intended to
prevent damage to the compressor motor
from successive restarts.
A Warning message indicates that a warning
setpoint has been reached, or exceeded.
Note: The remaining recycle delay time can
be cleared from the Motor screen
SHUTDOWN - This specific shutdown message
flashes when a shutdown is present. A shutdown
is a condition that requires an operator to acknowledge, and causes the compressor to shut
down.
COMPRESSOR STATUS BOX - Shows the present
operating status of the compressor and from what

If a Warning or Shutdown occurs, a flashing message will be shown, identifying the type of warning or
shutdown. As an example, if the Oil Temperature has
been less than or equal to the Low Oil Temperature
Warning setpoint for its time delay setting, then a
Low Oil Temperature Warning will be shown. If the
warning is not cleared by the operator, and the Oil
Temperature continues to drop to a point that is less
than or equal to the Low Oil Temperature Shutdown
setpoint for its time delay setting, then a Low Oil
Temperature Shutdown is issued, and the compressor, if running, will stop. The definitions for the two
types of messages are as follows:
A Shutdown message indicates that a shutdown setpoint has been reached, or exceeded.
When a Shutdown occurs, the display backlight will flash on and off to alert an operator

Start Procedure
Before starting a compressor, the leader must
determine that all running compressors are loaded and that the Suction Pressure has risen to a
point where an additional compressor is needed.
First, the leader checks that either no compressors are running or all the running
compressors average 90% capacity. If a running
compressor is at less than 90% capacity but is
in a Load Inhibit or Force Unload condition, for
the purposes of this calculation it is assumed
to be at 90% capacity.
If all the running compressors are loaded
the leader next begins comparing its Suction
Pressure to the Autocycle Start setpoint.
When the Suction Pressure rises above the
Start setpoint, the start timer is initiated. If
the start timer reaches the Autocycle Start
Delay setpoint time and the Suction Pressure
has remained above the Start setpoint for the
entire time, the leader
attempts to start an additional compressor. If the
Autocycle Start Delay setpoint is 0 minutes,
the leader still waits 15 seconds before
starting a compressor.
To determine which compressor to start, the
leader first sorts all the compressors in the system based on their start number, low to high. If
two compressors have the same start num-ber,
the first one on the list remains ahead of the
second. Next, the leader starts at the top of the
list and works down through list until it finds a
compressor that is available to run. To be
deemed available, a compressor must have
good sequencing communications and its
Compressor Mode and Capacity Mode must be
set as Remote Sequencing. In addition the
compressor must be off, and it cannot be in a
Start Inhibit condi-tion except for the Start
Inhibit Slide Value Too High condition. The
compressor with the lowest start number that
also meets these conditions is then sent a start
command. If no compressors are currently
available to start, the leader will continue
checking until one becomes available or until
the Suction Pressure drops below the Start
setpoint.
After a compressor has been sent a start
com-mand, the leader waits for that
compressor to reach a Running state. If 3
minutes passes and the compressor has not
yet begun to run, the leader sends it a stop
command. This com-

OPERATION
pressor is then fl agged as Unable to Start for 1
hour. After that time the leader may again try to
restart the compressor if additional capacity is
needed. After a compressor begins running, or
after one fails to start and is sent a stop command, the leader can begin the process of starting another compressor.
Stop Procedure
If the Suction Pressure drops to a point where
one of the running compressors is no longer
needed, the leader will stop the last compressor
in the sequence list.
When the Suction Pressure drops below the Autocycle Stop setpoint, the stop timer is initiated.
If the stop timer reaches the Autocycle Stop Delay setpoint time and the Suction Pressure has
remained below the Stop setpoint for the entire time, the leader attempts to stop one of the
running compressors. If the Autocycle Stop Delay setpoint is 0 minutes, the leader still waits 15
seconds before stopping a compressor.
To select the compressor to stop, the leader also
sorts all the compressors in the system according to their start number. Then the leader starts
at the bottom of the list and works up, looking
for a running compressor that can be stopped.
To be selected a compressor must have good
sequencing communications and its Compressor Mode and Capacity Mode must be set as Remote Sequencing. In addition, the compressor’s
run time must be greater than the compressor’s
Minimum Run Time setpoint. If the Minimum
Run Time setpoint is 0 minutes, a compressor
can also be stopped if it is still in Starting mode.
The compressor with the highest start number
that meets these conditions is sent a stop command. If no compressors are currently available
to stop, the leader will continue checking until
one becomes available or until the Suction Pressure rises above the Stop setpoint.
After a compressor has been sent a stop command, the leader waits for that compressor to
go to off. If 3 minutes passes and the
compressor has not yet turned off, the leader
then fl ags this compressor as Unable to Stop for
1 hour. After that time the leader may again try
to stop the compressor. After a compressor
goes to off or after one fails to stop within 3
minutes, the mas-ter can begin the process of
stopping another compressor.
Load/Unload
System Setup:
•
•
•
Control Input – Suction Pressure
Control Direction – Forward
High Stage Link – Disabled
Load Procedure
If the leader compressor’s Suction Pressure is
above the Capacity Control setpoint, the
leader calculates the increase in capacity that is
required. The calculation is as follows:
Difference = Suction Pressure – (Capacity Control Setpoint + Upper Dead Band)
If the Difference is less than the Upper Proportional Band:
Capacity Change = (Difference /
Upper Proportional Band) * Upper
Cycle Time
If the Difference is greater than the Upper Proportional Band:
Capacity Change = Upper
Cycle Time
After the capacity increase has been calculated,
the leader then fi nds the compressor whose capacity should be changed. To make this determination, the leader sorts all the compressors
based on their start number. Beginning at the
compressor with the lowest start number, the
leader fi nds the first compressor on the list that
is running but is not at its maximum capacity. A
compressor is at maximum capacity if it is at
100 percent capacity or if it is in a Load Inhibit
or Force Unload condition.
If the selected compressor is running the Quantum™ LX software, the capacity increase is
added to the compressor’s current capacity. This
new value is then sent to the compressor as its
Capacity Command, and that compressor will try
to increase its capacity to match the Command
value.
If the selected compressor is controlled by a
Quantum™ 1-4 or a Plus panel, the capacity
increase is interpreted as the time period for a
load pulse and is sent to the compressor as a
load command. The follower compressor will
then turn on its load output for the given
number of seconds.
Unload Procedure
If the leader compressor’s Suction Pressure is
below the Capacity Control setpoint, the leader
calculates the decrease in capacity that is required. The calculation is as follows:
Difference = (Capacity Control
Setpoint - Upper Dead Band) –
Suction Presure
If the Difference is less than the Lower Proportional Band:
Capacity Change = (Difference /
QUANTUM™ LX COMPRESSOR CONTROL PANEL
OPERATION
Lower Proportional Band) * Lower
Cycle Time
If the Difference is greater than the Lower Proportional Band:
Capacity Change = Lower
Cycle Time
After the capacity decrease has been calculated,
the leader then finds the compressor whose
capacity should be changed. To make this determination, the leader sorts all the compressors based on their start number. Beginning at
the compressor with the highest start number,
the leader finds the last compressor on the list
that is running and whose capacity is above its
Minimum Capacity setpoint. If two compressors
are currently running at or below their Minimum
Capacity setpoints, the leader will not allow any
additional compressors to unload. This will allow the Suction Pressure to continue to drop
and will cause the leader to turn off one of the
unloaded compressors. If the leader sees that
only one compressor is running in its system, it
will continue to unload the compressor down to
the leader's Automatic Capacity Mode Minimum
Slide Valve Position setpoint.
If the selected compressor is running the Quantum™ LX software, the capacity decrease is subtracted from the compressor’s current capacity.
This new value is then sent to the compressor as
its Capacity Command, and that compressor will
try to decrease its capacity to match the Command value.
If the selected compressor is controlled by a
Quantum™ 1-4 or a Plus panel, the capacity decrease is interpreted as the time-period for an
unload pulse and is sent to the compressor as
an unload command. The follower compressor
will then turn on its unload output for the given
num-ber of seconds.
High Stage/Booster
The High Stage System Link setpoint is provided
to tie a system of Booster compressors to a system of High Stage compressors. For example, if
the Booster compressors are setup on System #1
and the High Stage Compressors are on System
#2, the High Stage System Link setpoint from
System #1 would be set as System 2.
When the Booster System’s leader wants to
start the fi rst Booster compressor, it first checks
that a Booster compressor is available to run
and then sends a signal to the High Stage
System’s leader telling it to start a High Stage
compres-sor. If all the High Stage compressors
are off, the High Stage System’s leader will start
its fi rst compressor, regardless of what the High
Stage Control Input is reading. When the
Booster Sys-tem’s leader observes that a High
Stage com-
090.022-O (JUN 11)
Page 15
pressor is running, it will allow a Booster compressor to start.
After the first High Stage compressor begins
to run, compressors in both systems will cycle
on and off as their Control Inputs move up and
down. The only stipulation to the control strategy is that one High Stage compressor must always remain on as long as at least one Booster
compressor is running. If all the Booster compressors turn off, the High Stage compressor can
then turn off as well.

Maintenance
DESCRIPTION: Using this screen, the user can view up to nine (9) pre-programmed maintenance schedules, as well as
eight (8) user definable maintenance schedules. Each of the user defined schedules may be custom named. This screen
is based upon the Maintenance Schedule that is provided in the IOM manual for the specific compressor package.
The usage of this screen is that the user can assign up
to seventeen different areas of compressor operation
that they would like to schedule routine maintenance for.
As an example, the above screen shows a row labeled
as Oil Analysis. The next column (Service Every) on the
same row has a value of 10000 Hrs. The last column
(Next Scheduled At) of this row has a value of 1000 Hrs.
When the compressor is running, this time value is being clocked. After 1000 hours of compressor run time, a
message will be generated and placed on the Event Log
screen. This particular message will read Maintenance
-- Oil Analysis. This is to notify the operator that it is
time to have the Oil checked. At this point, the operator
should notify the proper maintenance personnel that the
appropriate maintenance be performed. The user should
access the Event Screen on a regular basis (perhaps once
per week) to review the information provided there.
Once the message has been entered in the Event Log,
the values for the row will be automatically updated, with
new values as predetermined by an internal programmed
maintenance schedule, based upon the type of compressor. The values for the Next Scheduled at column are
based upon the Compressor Run Time hours (shown at
the bottom of this screen).
At the bottom of the left-most column is the user defined Maintenance Required column. This is where custom
names may be entered for the various items that the user
would like to track.
Modifying numerical values
To modify any of the numerical boxes on this screen,
simply use the [Tab] key to scroll down the lists, or
the [Left Arrow] key to scroll up the lists. When the
box that you wish to change is highlighted, you may
enter the new value using the numerical keys, then
press the [Enter] key to accept the value.
Modifying Text (User Defined) Boxes
To modify any of the text boxes on this screen, simply use the [Tab] key to scroll down the lists, or the
[Left Arrow] key to scroll up the lists. Once the box

Mode
DESCRIPTION: The Capacity Control Mode 1 -4 screens are identical in appearance (with the exception that Low Suction will only appear if Suction Pressure has not been selected as the controlling mode). All setpoints having to do with
Capacity Control, Autocycle, Mode Safeties and Low Suction are found here.
Capacity Control is setup by accessing the Configuration
screen. From that screen, the user can enable or disable
any of the four possible modes, as well as select the channel that they wish to control from, and select whether the
control will be Forward or Reverse acting.
The Capacity Control screens shown above can display up
to four window areas of information:
•
•
•
•
Capacity Control
Autocycle
Mode Safeties
Low Suction
NOTE: If the Capacity Control mode is set to control
based upon suction pressure, then the Low Suction
window will appear blank, and the Mode Safeties
window values will act to protect the compressor for
Low Suction situations. If Capacity Control is not controlled from Suction Pressure, then the Low Suction
window will be populated with values because the
Mode Safeties window will act to monitor the Capacity Channel, but Low Suction data must also be
monitored simultaneously.
the Capacity Control is in the AUTO (Automatic)
or in REM SEQ (Remote Sequencing) modes.
Proportional Band High - A band, measured in
the units of the Capacity Control setpoint, above
the Dead Band High, where proportional load or
unload control is used. If the actual reading rises
into this proportional band the load or unload
output will be pulsed as explained below in the
description about proportional band.
Proportional Band Low - A band, measured in
the units of the Capacity Control setpoint, below
the Dead Band Low, where proportional load or
unload control is used. If the actual reading falls
into this proportional band the load or unload
output will be pulsed as explained below in the
description about proportional band.
CAPACITY CONTROL - Capacity Control can be set to
act in either Forward or Reverse control. In Forward
control, as the value of the capacity control channel
increases the Quantum LX increases the capacity of
the compressor. In Reverse control, as the value of
the capacity control channel decreases the Quantum
LX increases the capacity of the compressor. The following setpoint boxes are provided:
DESCRIPTION OF PROPORTIONAL BAND
CONTROL: The Proportional Band setpoint
determines a range of Capacity Control values where pulsed output control is used.
Outside of the proportional band the output is continuously energized. The length
of time the output will be pulsed on is proportional to the distance the actual reading
is from the Capacity Control setpoint. The
further the distance from setpoint, the longer the output is pulsed on and the shorter
the output is off. The closer the distance to
setpoint, the shorter the output is pulsed on
and the longer the output is off. If the actual
reading is midpoint from setpoint, the output is on and off an equal amount of time.
Setpoint - This setpoint is used to control the
loading and unloading of the compressor when
Dead Band High - A band, measured in the units
of the Capacity Control setpoint, above the set-

OPERATION
point at which the compressor will neither load
nor unload.
Dead Band Low - A band, measured in the units
of the Capacity Control setpoint, below the setpoint at which the compressor will neither load
nor unload.
Cycle Time High - This setpoint determines the
amount of time in seconds that the load or unload output is on and off, when in the upper proportional band. Refer to the description below
about cycle time.
Cycle Time Low - This setpoint determines the
amount of time in seconds that the load or unload output is on and off, when in the lower proportional band. Refer to the description below
about cycle time.
DESCRIPTION OF CYCLE TIME: The Cycle
Time setpoint determines the total amount
of time for one on/off cycle, when in the
proportional band. At the completion of the
cycle time the actual reading and necessary
response is re-evaluated. If a four second
period is selected, then the following will
result:

VFD Proportional Band - This is the value above
the Capacity Control setpoint for forward action
at which the output to the drive will match the
maximum output setpoint. Typically, proportional
control alone will not permit running at the control setpoint. If the pressure is within the proportional band but not increasing the output will not
increase with proportional control only.
VFD Integration Time - This is the value that
sets the increase of the proportional component
over time.
Example:
Actual Value = 21 PSIG
Capacity Control [20 PSIG]
Maximum Output [100%]
Minimum Output [20%]
VFD Proportional Band [4 PSIG]
VFD Integration Time [30 sec]
090.022-O (JUN 11)
Page 31
With the actual pressure at 21 PSIG, the
proportional component would be 20%. The
Proportional Component is calculated as:
[(Actual Value – Setpoint) / PB] X (Maximum output – Minimum Output).
[(21 – 20) / 4] X (100 – 20) = 20%
When this proportional component is added
to the minimum outpoint setpoint, the total output is 40% proportionally at an actual
value of 21 PSIG. It is the Integration Time
setpoint which will increase the output over
time without an increase in the actual value.
As long as the actual value, (21 PSIG) does
not change, the Integration Time setpoint,
in this case [30 sec], will increase the output
by the proportional component over every
30 seconds to drive the actual value back to
the Capacity Control setpoint. If the actual
value remains 21 PSIG, the Integration Time
Setpoint would increase the drive output to
100% over 1.5 minutes.
The following status indicator is provided:
Channel - Shows which analog channel is
being used to control this mode, as set on
the Compressor Configuration screen.
AUTOCYCLE - The following setpoint boxes are provided:
Start - The compressor turns on when the value
of the capacity control input reaches this setpoint. This setpoint is used in both AUTO (Automatic) or in REM SEQ (Remote Sequencing)
modes.
Start Delay – The time in minutes that the value
of the capacity control input must be above (forward) or below (reverse) the start setpoint before the compressor will start.
Stop - The compressor is stopped when the
value of the capacity control input reaches this
setpoint. This setpoint is used in both AUTO
(Automatic) or in REM SEQ (Remote Sequencing) modes.
Stop Delay - The time in minutes that the value
of the capacity control input must be below (forward) or above (reverse) the stop setpoint before the compressor will stop.
MODE SAFETIES:
Forward Acting – As the Capacity Control value drops below the capacity control setpoint,
these setpoints will protect the compressor by
decreasing the capacity, or if necessary shutting
down the compressor.
090.022-O (JUN 11)

ing will occur if the Process Temperature drops below 35.0 F.
If the Control Direction for a Mode is set to Reverse, its Safeties are activated as the Control
Channel’s value rises above the Safety Setpoints.
Example:
•
Force Unload - This setpoint will actively decrease the capacity of the compressor to avoid reaching the warning and shutdown setpoints.
Control Channel = Discharge Pressure
Control Direction = Reverse
Safety Load Inhibit Setpoint = 170.0
PSIG
•
Warning - If the Capacity Control value
is less than (forward) or greater than (reverse) this setpoint for the Warning Delay, a
warning occurs.
Note: For the above conditions a Load
Inhibit condition will occur if the Discharge Pressure rises above 170.0 PSIG.
•
Shutdown - If the Capacity Control
value is less than (forward) or greater than
(reverse) this setpoint for the Shutdown Delay, a shutdown occurs.
Each of the four Modes has a set of Safeties and
Low Suction Safeties. Additionally, each also has
a Control Channel and is configured with a Control Direction of either Forward or Reverse. The
Safety Setpoints monitor the Control Channel for
their Mode.
If the Control Direction for a Mode is set to Forward, its Safeties are activated as the Control
Channel’s value drops below the Safety Setpoints.
LOW SUCTION - The following setpoint boxes are
provided (NOTE: This box will be empty if Suction
Pressure has been selected as the Mode control
channel):
•
Load Inhibit – As the suction pressure drops
below this setpoint, the compressor is prevented from loading.
•
Force Unload – When the suction pressure reaches this setpoint, the capacity of
the compressor will be decreased to avoid
reaching the low warning and shutdown
setpoints.
•
Warning - If the Suction Pressure is less
than this setpoint for the Warning Delay, a
warning occurs.
•
Shutdown - If the Suction Pressure is less

System 1 Setup
DESCRIPTION: This screen will be available if Sequencing is enabled in Compressor configuration. The screen shown
represents Sys tem 1. There are additionally a System 2 and a System 3 setup screen, which are not discussed further
here, as all three screens show the same layout, although they may get setup using different capacity modes. Use
these screens to setup all of the necessary operating parameters for performing compressor sequencing. The information from these three screens will be shown on the Sequencing Status screen.
The following pull-down menus and setpoint boxes are
shown here:
Sequencing - Use this menu to set the current condition of System 1:
•
•
Disabled - The compressors that are listed
on this screen will not run as part of the sequencing scheme (System 1 will be ignored).
Enabled - The compressors that are listed
on this screen will run when called for as
part of the sequencing scheme (System 1
will be included).
Setpoint - Use this setpoint box to set the value that
you wish all compressors within this System to maintain.
Control Point - This is the actual value for the
capac-ity control (as measured from the Leader
compres-sor). The leader compressor is the unit
with the low-est IP Address. It is to this value that
the compressors will attempt to maintain. This is
strictly a displayed value, and cannot be changed
here.
Minimum Run Time - This is the minimum
amount of time that each compressor within this
system will
run, when called upon to do so.
High Stage System Link - The High Stage System
Link setpoint is provided to tie a system of Booster
compressors to a system of High Stage compressors.
The following is an informational box only:
IP Address - A unique identification number that every computer/processor that has a connection to the
Internet or an Ethernet network. Each compressor
will have a different IP Address. This value should be
entered by the network or LAN administrator, and will
be shown here. Use the last three digits of this number for setting the Sequencing ID number for each
compressor within the system. For example, from the
IP shown on this screen, use 194 to enter into one
of the eight Sequencing ID boxes at the left of the
screen. This will identify which compressor is being
communicated to with sequencing instructions.
There are eight rows of setpoint boxes shown at the bottom of this screen. These rows correspond to up to eight
different compressors, which combined will make up this
system. The user may program as few or as many of these
rows as their situation requires:

compressors to the Leader. A row with a 0 (zero) as
the sequencing ID will be ignored. The lowest number
will identify which compressor is to be the Leader. If
the Leader is for some reason turned off, the next
lowest numbered compressor will become the
Leader and so on.
Start # - The allowable numbers here are 0 – 8. This
number determines which compressor to start or
stop next, based upon capacity need (see pages 13

is 100%, then the slide stop will be given
an increase command simultaneous to the
slide valve unload command. Once the slide
valve has moved by a value in percent that
is equal to the Capacity Unload Assist setpoint, a decrease command will be given to
the slide stop while the slide valve continues
to receive a unload command. If the Vi or
volume ratio is greater than 4.8 and the slide
valve is 100% the slide stop will be given
a decrease signal simultaneous with a slide
valve unload signal. Once the slide valve is
seen to have moved by a value in percent
that is equal to the Capacity Unload Assist
setpoint, the slide stop will be allowed to
move back to the proper operating position
based on compression ratio.
[Start Differential Pressure Below] – The
compressor will be inhibited from starting if
the difference between the Discharge Pressure minus the Suction Pressure is greater
than this setpoint.
High Discharge Pressure:

[Starting Period Before Permitting Capacity Increase] – This setpoint indicates the
time period after the compressor goes to
the Running State that the Slide Valve will
not be allowed to load.
•
•
•
[Stopping Period for Capacity Unload] –
When the compressor is commanded to
stop, the Slide Valve will unload for this period, or until the Slide Valve is at or below
the Highest Capacity to Permit Starting setpoint.
[Compressor Automatic Mode Minimum
Capacity] – When the compressor is Running and the Compressor Mode and Capacity Modes are both in Automatic, the Slide
Valve will be loaded so as to keep the Capacity at or above this setpoint.
[Capacity Unload Assist] – A drop down
menu is provided to either enable or disable
this feature. When enabled, this control will
break the possible hydraulic lock between
the slide stop and slide valve that may occur, particularly with large diameter rotors
(283 & 355mm compressors). If the Vi (volume ratio) is 4.8 or lower and the slide valve

SETPOINTS – MOTOR (VFD, VYPER™)

Motor
… important for the safe operation of the compressor and motor.
DESCRIPTION: Drive safeties are
The information that appears on the left side of the screen
is described in the previous section under Setpoints - Motor.
The right side of the above screen is devoted to VFD and
VYPER™ (Variable Frequency Drives).
DESCRIPTION OF VFD OPERATION
Relying on user input as well as system pressures and
temperatures, the Quantum™ LX directs the VFD to
start or stop the compressor and change the compressor’s speed to regulate capacity. The setpoints
that primarily control the operation of the VFD are
found on the Quantum LX’s Capacity Control Setpoints and Motor Setpoints pages.
To start the compressor, the Quantum™ LX sends a
signal to the VFD to turn on the motor. When the VFD
receives the start command, it turns on the motor
and ramps up to the speed set by the VFD Minimum
Drive Output setpoint. At the same time if the slide
valve is below the Variable Speed Minimum Slide
Valve Position, it immediately loads to the Variable
Speed Minimum Slide Valve Position.
As more capacity is required, the Quantum™ LX
loads the slide valve. The Capacity Control Settings
(on the Motor Setpoints page) can be configured to
cause the motor speed to increase at the same time,
but in most VFD applications the Capacity Control
Drive Speed setpoint is set to match the Minimum
Drive Output setpoint. In this configuration the mo-
tor speed will remain at its minimum speed until the
slide valve loads above the Capacity Control Slide
Valve setpoint. If the slide valve cannot load due to a
slide valve load inhibit condition or because the compressor cannot build differential pressure, the motor
speed will increase to meet the capacity requirement.
When the slide valve reaches the Capacity Control
Slide Valve setpoint, the motor speed can then increase. At this point the slide valve and motor speed
can continue to increase independently of one another until the capacity requirement is met or they reach
their maximum values. If the compressor is in Auto
mode, the motor speed is controlled by the VFD Proportional Band and VFD Integration Time setpoints.
If less capacity is required, the Quantum™ LX will first
decrease the motor speed. The motor speed can drop
as low as the Capacity Control Drive Speed setpoint.
When the motor speed reaches this point, depending on the Quantum™ LX’s configuration, the slide
valve may unload or the Quantum™ LX may stop the
compressor. If the slide valve is permitted to unload,
it will not unload below the Variable Speed Minimum
Slide Valve Position while the compressor is running.

the value of the second setpoint [20%] from the
Minimum Output setpoint. If the second setpoint,
also known as the Proportional Speed setpoint
was set at [50%] the speed would increase proportionally from the Minimum Output setpoint
[20%] to [50%] as the slide valve loads from 0%
to 95%. In this case, that would be an increase of
approximately 1% speed to every 3% slide valve.
Skip Frequency Bands - These setpoints provide
the ability to lockout 5 frequency bands where
abnormal noise may occur due to the resonance
of various components throughout the speed
range. The slide valve needs to be at 100% when
the speed range is run through to detect these
bands. The limit is 5% from bottom to the top of
each band lockout.
During drive ramp up, these bands will be
skipped.
[Rate of Decrease] - The rate of speed
decrease over the duration of the Delay
setpoint when either a serial unload command is received or a digital unload signal
is received. This also sets the rate at which
the panel will cause a Force Unload for high
or low pressure and separator velocity. For
Force Unloading the Rate Of Decrease is
two times the value of the setpoint.
Capacity Control – The first setpoint in the Capacity Control section [95%] is the slide valve
position at which the speed will be allowed to
increase to maintain the capacity control setpoint. It also represents the slide valve position
of which the speed will increase proportionally to

Mode – This value is read from a switch
within the DBS, and will show whether the
starter is set to run at Constant Current, or
is set to Step Ramp. This is set at installation and is shown here for informational
purposes only:
•
Constant Current - In this mode, the current during starting is maintained at a constant level, field adjustable from 200 to
425% of FLA. At full speed, the current is
determined by the motor load.
•
Ramp - In this mode, the starting current
quickly reaches the constant current level
and then ramps up to 500% FLA. The ramp
time is adjustable from 3-30 seconds. At
full speed, the current is determined by the
motor load.
•
Heatsink Temperature – This will display
the value of a heatsink thermostat that is
located on the DBS control board. If this
thermostat opens (at 85° C), a fault will occur, and the motor will shutdown. The unit
will only be able to re-start when this thermostat resets (after be allowed to cool) at
60° C.
•
RTD Temperature – An RTD (resistive)
temperature sensor is located on the DBS
starter. This value is compared against the
RTD Temperature Warning Level and RTD
Temperature Trip Level setpoints and if the
value shown exceeds either of these setpoints, either a warning or a trip will occur.
•
Thermal Capacity – The allowable amount
of thermal energy that can be absorbed before damage may occur to the motor. This
value is based upon an internal calculation.
•
DBS Time Until Start – The motor has exceeded its Thermal Capacity and will not
be allowed to start until enough time has
elapsed to allow the motor to cool.
•
•
Bypass Time – When the controller is set
for Constant Current, a 10-position switch
(SW3) on the main control board of the DBS,
(adjustable from 3-30 seconds) sets the bypass time. The bypass time for Step Ramp
mode is 5 seconds, plus Ramp time.
Ramp Time – A 10-position switch (SW3),
on the main control board of the DBS, is

adjustable from 3-30 seconds and sets the
time in seconds in which the current rises in
the Step Ramp mode from its initial Current
Step level to 500% FLA.
•
Constant Current Level – A 10-position
switch (SW2), located on the main control
board of the DBS, sets the initial current
step of the controller in either Constant
Current or Step Ramp mode. This switch is
adjustable from 200-425% FLA for smooth
acceleration. When the controller is set for
Constant Current, this switch sets the maximum current limit for the motor in this mode
of operation. This current is maintained until the motor reaches full speed. When the
controller is set for Step Ramp, this switch
sets the initial current limit, and then allows
the controller to continue its ramp to 500%
FLA.
•
Thermal Overload Status – If this feature
has been enabled, then a trip will occur
if the thermal energy stored in the motor
exceeds 100% of motor Thermal Capacity.
The estimated temperature of the motor
windings is calculated based on the highest phase current. The overload trip level is
computed based on the following setpoints:
Full Load Amps, Locked Rotor Current, Stall
Time, and Service Factor. A start will not
be allowed until the motor has sufficiently
cooled.
The following setpoint boxes are provided. These
setpoints are updated via communications to the DBS
controller. When a setpoint has been changed and
submitted from the Quantum™ LX, it is sent to and

DESCRIPTION: Scheduling allows the user to program up to four different operating schedules for each day of the
week. This can be a great way to save energy. At night or on weekends and holidays, or even over lunch periods when
room doors are kept closed or production is minimized, a higher temperature can be set to reduce energy consumption.
This screen shows a time schedule. Up to four different
modes can be entered for each day of the week.
Notice that there are four columns of Hour/Minute entries,
each followed by a Mode (1 - 4). Use the left most column (on the row for the day of the week that you wish to
schedule) to enter the time of day that you would like the
compressor to switch form it’s normal operating mode,
into the scheduled mode. When that time of day arrives,
whatever mode the compressor WAS running in, will be
switched over to the scheduled (Mode 1 -4) mode. This
mode will then be the active running mode, and will continue to be the active mode until the time in the following
column is reached. If the time in the next column is 00:00,
it will be skipped.
The Schedule must be activated to switch the presently
active Mode to the Scheduling mode at the assigned time.
An entry of 00:00 will void the time entry field. If setback
is required at midnight (00:00) use 00:01.

[Actual] - The Actual value of the input signal. This is
not a setpoint value.
[Setpoint] - Enter the value that you wish to control
to.
[Proportional Band] – This setpoint determines the
size of a region either above or below the Control
Setpoint. Within this region, the Proportional component of the PID Output value is the number between
0% and 100% that directly corresponds to the difference between the Control Input (Actual) and the
Control Setpoint (Setpoint). Outside of this region,
the Proportional component is either 100% or 0%.
If the PID’s Action is Forward, the Proportional Band
extends above the Control Setpoint. If the PID’s Action is Reverse, the Proportional Band extends below
the Control Setpoint.
[Integration Time] - This setpoint controls the influence that the Integral component exerts on the
PID Output value. The Integral component works to
push the Control Input toward the Control Setpoint by
tracking the difference between the Control Input and
the Control Setpoint over time.
[High Limit] - The highest value that the output can
be.
[Low Limit] - The lowest value that the output can
be.
[When Running Off Value] - If the PID’s Control is
When Running, this value sets the value of the PID
output when the compressor is off.
Setting up a PID Channel
NOTE: The basic steps in setting up a device for PID
control is:
Setup Input channel
•
First, decide which physical input channel
you will be using. Note: If you wish to use
an Auxiliary Analog channel, it will require
being completely setup as its own chan-
090.022-O (JUN 11)
Page 53
nel before attempting the remainder of this
procedure.
Setup PID parameters
•
From the Operating Status screen, access
the Menu. Scroll down and select the [Setpoints] key. At the Setpoints menu, scroll
down to PID Setup and select it. Finally, on
the PID Setup menu, select [Page 1].
•
On the PID Setup screen, use the [Tab] key
to access the Analog channel that has already been set up, in this case, channel 1.
•
It is on this Setup screen that the remainder
of the PID parameters are entered. For a detailed description of these parameters, refer
to the Overview to Tuning a PID Controller.
Note: Each device that is utilized for PID control must
also be properly calibrated.
Overview to Tuning a PID Controller
The purpose of this section is to give some basic
guidelines for tuning Proportional, Integral, and Differential gains of a PID controller. To tune a PID controller, it would be advantageous to hook the system
up to some test equipment to allow you to record the
appropriate variables. At the very least, the appropriate data will have to be monitored and recorded by
hand from the system screen for subsequent evaluation and possible spreadsheet graphing.
Proportional Band
The Proportional Band setpoint translates the
Proportional Gain into the units of the Control
Input channel. When the control Input is at the
Control Setpoint, the Proportional component of
the PID Output will be 0%. As the Control Input moves through the Proportional Band, and
away from the Control Setpoint, the Proportional
component will increase. If the Control Input is
in the middle of the Proportional Band, the Proportional component value is 50%, and when the
Control Input reaches the outside of the Proportional Band, the Proportional value will be 100%.
The value of the Proportional component is calculated as the difference between the Control
Input and the Control Setpoint, divided by the
Proportional Band and then multiplied by 100.
Example:
Control Input:
Discharge Temperature
Control Setpoint: 100° F
Dead Band:
0° F
Proportional Band:
10° F
Action: Forward

The value selected for the Proportional Band will
be determined by the stability of the system, the
accuracy required, and the average output value,
among other things. One way to pick a starting
value is to find a range of allowable Control Input values and then to select a Proportional Band
so that the Proportional value will reach 100%
before the Control Input moves outside of the
allowable range.
After the initial value is entered for the Proportional Band, watch the system to see how it reacts. If the PID output shows too much oscillation, increasing the Proportional Band will cause
the control to react slower, which will dampen
this oscillation. If the PID reacts too slowly, then
decreasing the Proportional Band will make the
control react faster.
Proportional Only Control - There will be certain applications in which only proportional control is required for good performance. When this
is the case, the Integration Time can simply be
set to zero, and the Proportional Band set to a
desired value.
Some advantages of only using Proportional
control are that it is generally more stable than
Proportional and Integral control, and its function
is easier to understand. A disadvantage of only
using Proportional control is that the Control In-
put usually will settle into a spot somewhere in
the Proportional Band, and will not move to the
Control Setpoint. For instance, from the example
shown above, if the Proportional Output averages 80%, then the Control Input will remain at
108° F and will not go to 100° F. This may be
acceptable in some applications. In certain other
cases the setpoint can be offset to move the
Control Input to the point it needs to be.
Integration Time - The Integral calculation in
PID control uses past performance to calculate
a value for the PID output. It does this by periodically adding a small value to the PID output
to move the Control Input toward the Control
Setpoint. Eventually, the Integral component of
the PID output will equal the average PID output
value as Control Input gets to the Control Setpoint, and the Proportional component goes to
0%. When combined with the Integral calculation, the Proportional component can be negative and its range becomes -100% to +100%.
If the Control Input moves above or below the
Control Setpoint, the Proportional control will
prevent it from moving too far, and the Integral
control will move it back to the setpoint.
Once the Proportional Gain is set, start with a
large Integration Time (180 seconds). Here again,
you want to find the range of Integration Time
that gives you reasonably fast performance,
without too much overshoot, and without too
much oscillation. If the Control Input repeatedly overshoots the Control Setpoint, or oscillates too much, increasing the Integration Time
will slow the control. If the Control Input moves
too slowly toward the Control Setpoint, decreasing the Integration Time will cause the control to
react faster.

CALIBRATION - Analog Outputs
ACCESSING:

Analog Outputs…
Output Calibration
DESCRIPTION: This screen is used to calibrate individual analog outputs.
Use this screen if an analog output signal (channel) requires calibration.
The Quantum’s analog outputs have a range of approximately 0 to 25mA, but most devices that are controlled
by the Quantum™ LX require a signal that varies between
4 and 20mA. To restrict the analog outputs to the proper
values, each of the outputs must be calibrated before they
can be used. Every output channel has a Low End and
a High End value that are used for calibration. Both values can be set from 0% to 100%. The output channel’s
maximum value is represented by 100% and its minimum
value is represented by 0%. To calibrate the channel, the
High End percentage is decreased until the maximum output for the channel is limited to 20mA. Also, the Low End
percentage is increased until the minimum output for the
channel is 4mA.
5.
After the Analog Board and Channel Number
have been selected, the channel’s function will
be displayed below the Channel Number. If “Not
Configured” is shown here instead, the channel
has not yet been assigned a control function.
Return to step 1 and setup the channel for the
control task it is to perform.
6.
Press the [#1] key (Set Low End) and the value
shown on the meter should go to the channel’s
low end value.
7.
Check that the “Delta For Changing Output Percentage” value is 10.00. If not, press the [#0] key
(Change Delta) until it is displayed as 10.00.
8.
If the channel’s output is greater than 4mA press
the [#4] key (Decrement Output by Delta). If the
channel’s output is less than 4mA, press the [#7]
key (Increment Output by Delta). Use these keys
to find the output value closest to 4mA.
9.
Press the [#0] key (Change Delta) once to decrease the “Delta For Changing Output Percentage” value to 1.00.
Below is a step by step procedure for calibrating one analog output.
1.
Configure the analog output channel for its intended use, i.e., if the channel is to be used for
PID control, enter the Device Source and Device
Channel of the selected analog output channel
under one of the PID columns on the PID Setup
page.
2.
Set up a meter to read the channel’s output value in milliamps.
3.
Go to the Analog Output Calibration page.
4.
Select the Analog Board and the Channel Number for the output that is being calibrated.
10. Use the [#7] and [#4] keys to again find the value closest to 4mA.
11. Repeat steps 9 and 10 for Delta values of 0.1 and
0.01 to bring the output value as close as possible to 4mA.
12. Press the [#3] key (Set High End) and the value
shown on the meter should go to the channel’s
high end value.

14. If the channel’s output is greater than 20mA
press the [#4] key (Decrement Output by Delta).
If the channel’s output is less than 20mA, press
the [#7] key (Increment Output by Delta). Use
these keys to find the output value closest to
20mA.
15. Press the [#0] key (Change Delta) once to de-

crease the “Delta For Changing Output Percentage” value to 1.00.
16. Use the [#7] and [#4] keys to again find the value closest to 20mA.
17. Repeat steps 15 and 16 for Delta values of 0.1
and 0.01 to bring the output value as close as
possible to 20mA.
The analog output channel will return to its control task
either when another output channel is selected for calibration or when the user goes to another screen.

The following fields are provided:
IP Data:
[Address Type] - A drop down menu is provided:
•
•
Fixed (Static)
DHCP (Dynamic)
This should be set by the network administrator.
[IP Address] - Four setpoint boxes are provided.
The network administrator will enter the numerical IP address for this specific Quantum™
LX panel. This setpoint box will be automatically
assigned if the address type is set to DHCP.
[Gateway Address] - Four setpoint boxes are
provided. The network or LAN administrator will
enter the numerical Gateway address. This setpoint box will be automatically assigned if the
address type is set to DHCP.
[Subnet Mask] – Like IP addresses, a subnet
mask contains four bytes (32 bits) and is often
written using the same “dotted-decimal” notation. A subnet mask neither works like an IP address, nor does it exist independently from them.
Instead, subnet masks accompany an IP address
and the two values work together. This setpoint
box will be automatically assigned if the address
type is set to DHCP. Applying the subnet mask to
an IP address splits the address into two parts,
an extended network address and a host address. For a subnet mask to be valid, its leftmost
bits must be set to ‘1’. Conversely, the rightmost
bits in a valid subnet mask must be set to ‘0’,
not ‘1’. All valid subnet masks contain two parts:
the left side with all mask bits set to ‘1’ (the extended network portion) and the right side with
all bits set to ‘0’ (the host portion).
[Web Server Port] - One setpoint box is provided. The network administrator will enter the numerical address for this Web port (80 is typical).
Email Data:
[Email Notification On Shutdown] - For the Email notification feature to work, it must be enabled. The following menu is provided:
•

[Local Email Address] - Enter a valid E-mail address that messages are sent from.
[Alias Name For Local Email Address] - Enter
here a custom name to identify more clearly the
local Email address. When a message is sent to
all recipients, this is the name that will appear in
the Email FROM column.
[Subject] - Enter a custom subject that you
would like to have appear when a message failure is sent. When a message is sent to all recipients, this is the wording that will appear in the
Email SUBJECT column.

DESCRIPTION: This screen allows the user to set various levels of password protection. The Security screen shown
can only be modified at the Quantum™ LX control panel via the keypad (it is not available through a web browser).
The various levels are:
•
Level 0 - BASIC level. This level is not shown on
the Security screen, as it is the lowest level of system
access, and does not require a Password to activate.
This is the default level, and provides access to only
the very basics of machine operation.
•
Level 1 - ADVANCED level. This requires a password to set. Only users who are authorized with the
Password may enter this level. It provides greater access than Level 0 (BASIC). The valid entry range is 0
(zero) to 5000. The factory default value 10 (ten).
•
Level 2 - SERVICE level. This requires a password
to set. Only those users who are authorized with the
Password may enter this level. It provides greater access than Level 1. The factory default value for this
Password is 20 (twenty).
To set the password protection for the each level, use
the keypad to highlight the box beside the level that
you wish to change. Set the level to either zero (0) or
one (1) and enter the appropriate Password for that
level in the next box. The valid range for password
entry is -999999 to 999999.
NOTE: It is recommended that the supervisor docu-
ments this Password and stores it in a safe place. If
the Password is ever forgotten, it can only be corrected by calling the factory.

MISCELLANEOUS SCREENS
ALPHA
The Alpha screen shows a graphic representation of the
Quantum™-LX numerical keypad. It is accessible from any
screen that allows the user to enter alpha/numeric data,
such as the Maintenance screen, for example. The symbols that appear above each key on this screen are the
possible combinations of symbols that are associated with
the digital portion of the key. As an example, by pressing
the number 7 on the keypad will cause an alpha A to appear in the Current Character box. Pressing the number 7
again will cause the capital A to be replaced with a small
a (this is the next letter in the line above the numeral 7).
Continuing to press the 7 key will cycle through the remaining letters above the key, and then start over.
As an example, suppose that you wanted to modify the
text line in the screen example shown above. You want
to change the line from reading Oil, to Low Oil 2. The first
thing you would do, is to use the [Left Arrow] key on
the keypad, to position the cursor (blinking vertical line),
to the far left side of the text. Press the number [4] key
(notice that the capital L, for Low, is one of the symbols in
the line right above the numeral [4] key). A capital J will
appear in the Current Character box. Continue press the
numeral [4] until the capital L appears there. Now press
the [Up Arrow] key and notice that the L has been placed
on the text line in the first position. Next press the numeral [5] key on the keypad, and continue pressing it until
the small o appears in the Current Character box. Press
the [Up Arrow] key to place the o on the text line. Now
to finish the word Low, press the [2] key until the small w
appears in the Current Character box, then press the [Up
Arrow]. This will complete the word Low, but we need to
add a space after it. The symbol for a space is ▯, which
is located above the [+/-] key. Press the [+/-] key, until
the Current Character box contains nothing (the ▯ does
not appear) then press the [Up Arrow] key to enter it on
the text line. Finally, use the [Right Arrow] key, to move
the blinking cursor to the right of the word Oil, and press
the [Up Arrow] key again to enter the space (since the
space was the last character entered, it can continue to
be placed as many times as you would like on the line by
pressing the [Up Arrow] key). After entering the space,
press the numeral [2] key until the digit 2 appears in the
Current Character box, then press the [Up Arrow] key.
When you are satisfied with the changes that you have
made, press the [Enter] key to accept them, and you will
be returned to the previous screen.

OPERATION OVERVIEW
conditions to remain satisfied for a period
of five seconds for all compressor model
types except [Other Compressor Manuf].
The Other compressor model type uses a
20 seconds delay. After the time delay the
compressor and the Recycle Delay timer are
started.
INITIAL SETUP PROCEDURE
1.
2.
Compressor Configuration should be performed by a Factory Representative or Distributor to setup the customer specific control features which should not need to be
changed by operators.
Configuration is performed to setup panel
features and options, which can later be
changed by an operator. Features such
as the panel time, and screen saver are
changed here. Options such as Condenser
Control are enabled here. The operator can
avoid viewing and entering settings of unused controls by keeping unused options
disabled.
3.
Calibrate the control devices.
4.
Enter and setup all control settings.
5.
Establish the desired access rights of the
operators.
6.
The Operating Status screen now provide
quick access to the most important information and controls of the compressor unit
and the subsystems.
COMPRESSOR START-UP PROCEDURE
•
Starting is shown for the Compressor status
on the Operating Status screen.
•
All the safeties are checked. If any shutdown
condition is present the corresponding
alarm message is shown and the compressor is prevented from starting.
•
If the compressor type has been set to Other Compressor:
•
The oil lubrication is checked. A Prelube pump needs a 5 lb. oil pressure
differential to allow the compressor to
start. A full time pump needs a 20 lb.
Oil Pressure differential to allow the
compressor to start. Other compressor manufacture’s Oil Pumps needs a
30 lb. Oil Pressure differential to allow
the compressor to start. If one of these
conditions is not present an alarm message is issued and the compressor is
prevented from starting.
•
The Slide Valve position is checked to see if
it is less than or equal to the Highest Slide
Valve Position to allow starting the compressor setpoint. If the Slide Valve position
is higher than this, the compressor is prevented from starting.
•
If none of the above conditions has prevented the compressor from starting, a timer
delay is started that requires the starting
•
If within 30 seconds, the Compressor Start
Auxiliary input has not been energized,
or Motor Current is not detected, then an
alarm message is issued and the compressor is shut down.
•
When the compressor begins running, the
Oil Pressure values are in a state of change.
For a period of 10 seconds after the compressor status switches to Running, the low
Oil Pressure alarm and shutdown safeties
are ignored.
COMPRESSOR STOPPING PROCEDURE
During the compressor stopping, the Slide Valve
unload solenoid remains energized until the Slide
Valve is unloaded to or below the Highest slide
valve position to allow starting the compressor setpoint. If the Slide Valve does not unload
below this setpoint within 5 minutes, the alarm
message Compressor Unable to Unload - Alarm
is issued.
SETUP FOR AUTOMATIC CONTROL
In order to operate a compressor at peak efficiency, under full load and part load conditions
complex control sequences must be used. In order to obtain the efficiencies, Automatic Control
is almost mandatory. Automatic control of the
Slide Stop and Slide Valve increases the compressor efficiency over a wide operating range.
The following steps (which are relevant) should
be taken to control in Automatic:
•
The compressor should be in automatic (automatic cycling) so the compressor will start
and stop according to the Autocycle setpoints.
•
The Oil Pump should be in auto because its
operation coincides with that of the compressor.
•
The Slide Valve and the Slide Stop should
be in Automatic so they are controlled by
setpoints and internal control logic.
Note: If there is a shutdown in response to a
safety setting, a compressor in Automatic mode
is placed into Manual mode requiring operator
intervention.
REMOTE CONTROL OF THE COMPRESSOR
The following digital outputs and inputs (on Digital Board 2) have been provided that can be used

the compressor is running or stopped
since the Recycle Delay is a start-tostart protection. It is intended to prevent damage to the motor from successive restarts. For further setup see the
Motor Control Setpoints screen
to control the compressor from another controller such as a PLC:
•
(Module 1) - Ready to Run - This output is energized while the compressor
is not shutdown and the Recycle Delay
has timed out.
•
(Module 2) - Remote Enabled - This
output is energized while the compressor is in Remote Start mode.
•
(Module 3) - Remote Start / Run /
Stop - If the compressor is in Remote
Start mode with no Recycle Delay time
and this input is energized, the compressor is started. If this input is energized and the compressor is started, it
will continue to run. If this input is deenergized, the compressor is stopped.
•
(Module 4) - Remote Load or Remote
C.C step 1 for step units
•
•
•
Remote Load - If the Slide Valve
is in Remote Mode and this input
is energized, the Slide Valve load
solenoid will be energized provided
there are no safety overrides preventing loading.
Remote C.C step 1 for step units
- If the Capacity Mode is in Remote
this input is used to step on and off
capacity according to the Remote
Capacity Control chart.
(Module 5) - Remote Unload or Remote C.C step 2 for step units
•
Remote Unload - If the Slide Valve
is in remote and this input is energized, the Slide Valve unload solenoid will be energized.
•
Remote C.C step 2 for step units
- If the Capacity Mode is in Remote
this input is used to step on and off
capacity according to the Remote
Capacity Control chart.

The Hot Gas Bypass option can be used. This option
is not available for all compressor models (Reference
090.020-M; Compressor Model Differences).
The Remote Control Setpoint option can be used.
This option, which is enabled in Panel Setup, is not
available for all compressor models (Reference Compressor Model Differences). This uses the Remote
Control Setpoint analog input and the Remote Control
Setpoint analog output for Capacity Control of compressors. For further setup see the Calibrate Remote
Control Setpoint screen and the [Remote Setpoint]
command key from the Slide Valve Mode screen
command keys on the Operating Status screen.
The Remote Slide Valve Position option can be used.
This option which is enabled in Panel Setup is not
available for all compressor models (Reference Compressor Model Differences). This uses a (4-20 ma) input signal to the Remote Slide Valve Position analog
input (Channel #13 on Analog Board #1) to control the
Slide Valve. For further setup see the Calibrate Slide
Valve Position screen and the [Remote Slide Valve]
command key from the Slide Valve Mode screen
command keys on the Operating Status screen.
The Slide Valve Position \ Capacity analog output can
be used to determine the present Slide Valve position % or Capacity % dependent on the compressor
model (Reference Compressor Model Differences). A
(4-20 ma) output signal to the Slide Valve Position \
Capacity analog output (Channel #3 on Analog Board
#1) corresponds to the present (%) value displayed on
the Operating Status screen.
ASCII communication to the Com-2 port can be used
(reference 090.020-CS Communications Setup manual). A compressor should be in both Remote Compressor Mode and Remote Slide Valve or Capacity
Mode for Remote Control.
Note 1: If the compressor is in Remote mode and
communication through the communication port has
not occurred for 5 minutes, then the compressor is
placed into Automatic mode and the Slide Valve is
placed into Auto mode.
Note 2: If there is a shutdown in response to a safety
setting, a compressor in Remote mode is placed into
Manual mode requiring operator intervention.

filter system is not sinusoidal. This fault occurs when
any of the three phases of Total Demand Distortion
is greater than 25.0 %, for forty-five continuous seconds while the Vyper™ is running.
Harmonic Filter Input Frequency Out of Range The Harmonic Filter monitors the line frequency on its
inputs. If this frequency is out of range, it will cease
filtering, and set a bit in the communications packet.
This warning is shown whenever this bit is set.
Harmonic Filter Logic Board Power Supply – This
shutdown indicates that one of the low voltage power supplies on the Filter Logic board have dropped
below their permissible operating voltage range.
Harmonic Filter Logic Board Or Comms Fault – This
fault occurs if the No Fault signal from the Vyper™ is
low, indicating a fault is present at the Vyper™ or the
Harmonic Filter, but the communications data contains no Harmonic Filter fault data for twenty seconds. The Frick Interface Board will send Initialize
data requests while this fault is active.
Harmonic Filter Low DC Bus Voltage – The DC link
voltage magnitude should remain within -80 VDC of
the bus voltage setpoint determined from the peak
input voltage. If the DC link voltage magnitude falls
outside this range for 100 msec the unit will trip and
the Quantum™ LX panel will display this message.
Harmonic Filter Phase Locked Loop Fault – This
shutdown indicates that a circuit called a “phase
locked loop” on the Filter Logic board has lost synchronization with the incoming power line for a period of time.
Harmonic Filter Precharge - High DC Bus Volt – The

seconds after the precharge signal has been asserted
on the 60 Hz VSD and at least 414 VDC within 20
seconds on the 50 Hz VSD. If not, the Quantum™ LX
panel will display this message.
Harmonic Filter Precharge - Low DC Bus Volt – This
fault has two different timing events. First, the DC Bus
voltage must be equal to or greater than 50 VDC for
60 Hz (41 VDC for 50 HZ) 4 seconds after precharge
has begun. Second, the DC Bus voltage must be equal
to or greater than 500 VDC for 60 Hz (414 VDC for 50
HZ) 20 seconds after precharge has begun. The unit
is shut down and this message is generated if any of
these conditions are not met.
Harmonic Filter Run Signal Fault – When a digital run command is received at the filter logic board
from the Vyper™ Logic board, a 1/10 second timer is
begun. A redundant run command must also occur
on the serial data link from the Vyper™ Logic board
before the timer expires. If not, the Vyper™ will be
shut down and this Fault message will be displayed.
Harmonic Filter Serial Communication – When
requesting Status data, the response data from the
Harmonic Filter includes a bit that indicates whether
communications were lost from the Vyper™ to the
Harmonic Filter. If this bit is high for twenty consecutive seconds, this warning is indicated. This warning is also indicated whenever a receive timeout, or
checksum fault is detected on the Harmonic Filter
communications, for twenty continuous seconds.
Harmonic Filter 110% Input Current Overload – The
overload threshold and timer functions reside in software on the Harmonic Filter’s Logic board. The unit’s
three phases of RMS output current are compared to
the overload threshold magnitude. If this threshold
is exceeded for 40 seconds the unit will trip and the
Quantum™ LX panel will display this message.

VSD Initialization Fault - At power-up, all the boards
go through a process called initialization. At this time,
memory locations are cleared, jumper positions are
checked, and serial communications links are established.
VSD Invalid Current Scale Selection – The J1 connector on the Vyper™ Logic board contains jumpers
along with wires from the output CTs. Since the part
number of the Logic board is the same on all horsepower sizes, the jumpers tell the logic board the size
of the Vyper™ being employed in order to properly
scale the output current. If the jumper configuration
is found by the Logic board to be invalid, the system will be shut down and the above message will
be generated.
VSD Logic Board Power Supply Fault – The various

is generated if a communications problem occurs between the two microprocessors on the Vyper™ Logic
Board. If this shutdown occurs, replace the Vyper™
Logic board.
VSD Low Converter Heatsink Temp Fault – The
phase bank assembly heatsink temperature and the
inverter module base plate temperature are compared to a lower limit of 37°F. If the inverter base
plate temperature or the converter heat sink temperature falls below 37°F, this message will be displayed.
In addition, if both temperatures fall below the 37°F
limit, the unit will trip and the fan(s) and water pump
will be energized.
VSD Low DC Bus Voltage Fault – The DC link under
voltage trip level must be set at 500 VDC for 60 Hz
and 414 VDC for 50 Hz VSD’s. If the DC link drops below this level, the unit will trip, and the Vyper™ Logic
Board will initiate a system shutdown.
VSD Low Inverter Baseplate Temp Fault – The
phase bank assembly heatsink temperature and the
inverter module base plate temperature are compared to a lower limit of 37°F. If the inverter module
base plate temperature falls below this limit the unit
will trip and the Quantum™ LX Panel will display this

the fan(s) and water pump will be energized.
VSD Low Phase B Inverter Baseplate Temp. – The
phase B heatsink temperature and the inverter module base plate temperature are compared to a lower
limit of 37°F. If the inverter module base plate temperature falls below this limit the unit will trip and
the Quantum™ LX Panel will display this message. In
addition, if both the inverter and converter temperatures fall below the 37°F limit, the unit will trip and
the fan(s) and water pump will be energized.
VSD Precharge Lockout Fault – If the Vyper™ fails to
meet the precharge criteria, then the precharge circuit
will wait for a period of 10 seconds. During this time,
the unit’s cooling fans and coolant pump remain energized in order to cool the input SCR’s. Following this
10-second cool-down period, precharge will again be
initiated. The unit will attempt to meet the precharge
criteria three consecutive times. If the Vyper™ fails
to meet the precharge criteria on three consecutive
tries, the Vyper™ will shut down, lock out, and display
this message. In order to initiate precharge again, the
Quantum™ LX panel’s compressor switch must first
be placed into the STOP/RESET position.
VSD Low Phase C Inverter Baseplate Temp. – The
phase C heatsink temperature and the inverter module base plate temperature are compared to a lower
limit of 37°F. If the inverter module base plate temperature falls below this limit the unit will trip and
the Quantum™ LX Panel will display this message. In
addition, if both the inverter and converter temperatures fall below the 37°F limit, the unit will trip and
the fan(s) and water pump will be energized.
VSD Precharge - DC Bus Voltage Imbalance – The
1/2 DC link voltage magnitude will remain within ±
88VDC of the total DC link voltage divided by two
during the precharge interval for both the 60 and 50
Hz VSD’s. If not, the Quantum™ LX panel will display
this message. The definition for this fault is identical
to “VSD - DC Bus Voltage Imbalance”, except that the
fault has occurred during the precharge period which
begins during prelube.
VSD Phase A Gate Driver Fault – The unit’s phase
bank assembly shall contain one IGBT gate driver
control board. This board monitors the saturation
voltage drop across the Phase A Gate Driver while
gated on. If the IGBT’s Phase A Gate Driver saturation voltage exceeds the prescribed limit, the gate
driver will make the determination that a short circuit
is present. This in turn shall cause the unit to trip
and the Quantum™ LX Panel shall display this message. If the driver board’s power supply voltage falls
below the permissible limit, this same message shall
be generated.
VSD Precharge - Low DC Bus Voltage 1 – The DC
link voltage will reach at least 50 VDC within 100
msec after the precharge relay has been pulled in on
the 60 Hz 519 filter and at least 41 VDC within 100
msec on the 50 Hz 519 filter. If not, the Quantum™ LX
panel will display this message.
VSD Phase B Gate Driver Fault – The unit’s phase
bank assembly shall contain one IGBT gate driver
control board. This board monitors the saturation
voltage drop across the Phase B Gate Driver while
gated on. If the IGBT’s Phase B Gate Driver saturation voltage exceeds the prescribed limit, the gate
driver will make the determination that a short circuit
is present. This in turn shall cause the unit to trip
and the Quantum™ LX Panel shall display this message. If the driver board’s power supply voltage falls
below the permissible limit, this same message shall
be generated.
VSD Phase C Gate Driver Fault – The unit’s phase
bank assembly shall contain one IGBT gate driver
control board. This board monitors the saturation
voltage drop across the Phase C Gate Driver while
gated on. If the IGBT’s Phase C Gate Driver saturation voltage exceeds the prescribed limit, the gate
driver will make the determination that a short circuit
is present. This in turn shall cause the unit to trip
and the Quantum™ LX Panel shall display this message. If the driver board’s power supply voltage falls
below the permissible limit, this same message shall
be generated.
VSD Precharge - Low DC Bus Voltage 2 – The DC
link voltage will reach at least 50 VDC within 100
msec after the precharge relay has been pulled in on
the 60 Hz 519 filter and at least 41 VDC within 100
msec on the 50 Hz 519 filter. If not, the Quantum™ LX
panel will display this message.
VSD Run Signal Fault – Upon receipt of either of the
two run commands, a 5-second timer will start. If the
missing run signal is not asserted within the 5-second window, the unit will trip and the Quantum™ LX
panel will display this message.
VSD Serial Communication Fault – When requesting Status data, the response data from the Vyper™
includes a bit that indicates whether communications were lost from the Frick Interface Board to the
Vyper™. If this bit is high for 22 consecutive seconds,
this fault occurs. This fault also occurs whenever a
receive timeout, or checksum fault is detected on
the Vyper™ communications, for twenty continuous
seconds. While this fault is active, the Frick Interface
Board will send Initialize data requests in order to
reestablish the communications link. All serial input
data is also cleared.
VSD Single Phase Input Power Fault – The Vyper’s™
SCR Trigger Control board contains circuitry that
checks the three-phase mains for the presence of all
three line voltages. If all line voltages are not present, the unit will trip and the Quantum™ LX Panel will
display this message.
QUANTUM™ LX COMPRESSOR CONTROL PANEL

VSD Stop Contacts Fault - This fault occurs if the
No Fault signal from the Vyper™ is low. It indicates
a fault is present at the Vyper™ or the Harmonic Filter, but the communications data contains no Vyper™
fault data for twenty seconds. The Frick Interface
Board will send Initialize data requests while this fault
is active.
VSD 105% Motor Current Overload Fault – The
Vyper™ Logic Board generates this shutdown by
reading the current from the 3 output current transformers. The shutdown is generated when the
Vyper™ Logic board has detected that the highest of
the three output phase currents has exceeded 105%
of the programmed 100% full load amps (FLA) value
for more than 40 seconds. If this is detected, the unit
will trip and the Quantum™ LX panel will display the
fault message.
090.022-O (JUN 11)
Page 103
Vyper™ Fault Limit Reached Shutdown - The
Vyper™ Logic Board generates faults as they occur.
If these faults are not of a potentially destructive nature, they are automatically cleared by the Vyper™
logic if the symptom that created the fault corrects
itself. The Quantum™ control tracks these self-clearing faults, and if a total of five faults occur within a
one hour period of time, a compressor shutdown will
occur.
