The User Interface Computer is a Pentium®
based PC with a non-volatile ash-disk that
contains a Windows XP® Embedded operating system and the RCS-2 user-interface software. It has an on-board Ethernet port to allow interface with the interface card. The computer has USB ports for updating its software and for backing-up parameter data. Keyboard and mouse ports are also available on the unit for setup, diagnostics, and troubleshooting, if necessary.
The control card rack is a half-width 19" rack with space for one RIO card, one interface card, and up to four channel cards. It is powered from 24 VDC and utilizes up to 9 ribbon cable con­nections (if all 8 channels are used). High speed communications between cards is accomplished using a Motorola® SPI bus.
LN-9407-00.2
Ransburg
RCS-2 User Manual - Introduction
The interface card houses a Rabbit 2000® embedded processor. This board performs the following functions:
• It handles all communications between the user-interface computer and the chan­ nel cards.
• It stores all parameter data in battery­ backed RAM.
• Has an Ethernet port used to communi­ cate with the user-interface PC and the color change sequencer.
• Handles all discrete system I/O (job num­ ber inputs, strobe inputs, system fault out­ puts, etc.).
Each channel card houses a Motorola® MC68HC16 embedded processor. These boards perform the following funtions:
• Controls all gun and channel specic dis-
crete inputs and outputs.
• Controls all gun and channel specic ana-
log inputs and outputs.
• Holds rmware for PID loops that control motor ampliers.
• Holds rmware for PID loops that control
inlet pressure transducers.
The LCD touch-screen display is a 15" di­ag-onal, full color LCD display with 1024 by 768
pixel resolution.
There is one DC power supply housed in the main control console. It supplies 24 VDC for all discrete I/O signals and for the boards in the control rack.
The ribbon cable interface boards provide easy screw-terminal access to all analog and digital input
and output signals. They also provide specic test
points to allow easy connection of test devices and data acquisition equipment.
On the top of the main control console there are up to eight 26-pin military-style connectors, one for each channel. These I/O connectors allow the main control console to be interfaced with the motor amplifer panel(s) via the 26-conductor "umbilical cables". Also, on the top of the main control panel are two Ethernet connectors used to connect to the interface card and user interface computer.
Motor Amplier Panels
The Motor Amplifer Panels act as the interface between the CPU on the channel cards and the "real world" devices such as motors, pressure
transducers, and ow switches. They house the
following items:
• Motor Drive Ampliers
• E to P Pressure Transducers
• Zener Barriers
• Interface Modules for Flow Sensor
• 24 VDC Power Supply
• Corr-Com Power Filter
• Control Relay
• Terminal Strip
• Optional Color Change Sequencer
The motor drive ampliers convert a 0 to 10 VDC signal from the channel cards to a propor­tional RPM (0 to 150) at the motors. They also receive the feedback from the resolvers attached to the motors. In this way, they can generate a fault if the actual motor RPM does not match the target RPM.
The E to P pressure transducers convert a 0 to 10 VDC signal or optionally a 4 to 20 mA signal from the channel cards to a proportional 0 to 100
psi air signal. This signal is used to pilot uid
regulators on the inlet of the pumps, allowing the channel card to control the inlet pressure of the pumps.
The terminal strip is used for connecting AC power to the unit and for access to the 24 VDC power supply for external I/O devices. The ter­minal strip has two fuses, one for the incoming AC power and one for the 24 VDC control power. On the buttom of the terminal strip is a Corr-Com®
power lter for the incoming AC.
LN-9407-00.2
The optional Zener barriers make the pressure sensors and the optional Remote Operator's Panel intrinsically safe for use inside the spray area.
The optional catalyst ow sensor interface
module powers and monitors the ow sensor

RCS-2 User Manual - Introduction
Ransburg
typically used in the catalyst line of the uid panel. An additional module converts the ow signal to a 4 to 20 mA signal that is proportional to the ow
rate of the catalyst. That signal is then fed back to the channel card so it can be used to generate
faults when catalyst ow falls below a preset point
or if air is detected in the supply line.
The 24 VDC power supply powers the E to P
transducers, the pressure sensors, catalyst ow
sensor modules, and the optional Remote Oper­ators's Panel.
If the optional color change sequencer is installed, this power supply will also have a +5 VDC output to power the color change sequencer.
The optional Color Change Sequencer is a small
P.L.C. like processor that controls the ush, load,
and color change sequences for each gun and job number. Each time a job number is loaded
into a gun, the ush and load sequences are
downloaded to this controller. (A color change
sequence is simply a ush sequence followed by
a load sequence.)
The pump manifolds house the magnetic cou­plings which tie the servo motors to the gear pumps.
The servo motors actually house both an AC drive servo motor and a feedback resolver in the same physical housing. They get their drive signals
from the motor drive ampliers and the resolvers
feed their rotational information back to the motor
drive ampliers. (Explosion proof servo motors
are available as an option.) The pressure sensors convert the uid pressure
from the uid inlet and outlet of the pumps to a
4 to 20 mA signal which is then fed through the zener barriers and back to the channel boards (in the control rack). Standard units have a pressure range of 0 psi to 200 psi.
The catalyst ow sensor is a thermal shedding
type ow sensor that is immersed in the catalyst ow stream. It detects ow by heating the sensor
and then sensing how much of the heat is being
removed from the sensor by the ow of catalyst. (More ow = more heat removed from the sensor head.) An optional explosion-proof version of this
sensor is available for use in hazardous areas.
Fluid Panels
The Fluid Panels contain all of the "wetted" com­ponents for the RCS-2 as well as the drive motors. These include:
• Gear Pumps
• Pump Manifolds
• Servo Motors
• Pressure Sensors
• Catalyst Flow Sensor (optional)
• Mix-Block
• Spiral Mix Tube
• Color Valve Stack (optional)
• Solvent Manifold
• Pump Bypass Valve
The gear pumps are available in various sizes for
various materials and ow rates. Users should
consult Ransburg technical support group to determine which pumps are required for their
specic application. (Refer to "Appendix B" for a
list of currently available pump sizes.)
The Mix-Block is a three-port manifold that brings
the uid from the outlet of the resin pump together
with the outlet of the catalyst pump. The block houses a check valve in the catalyst stream to prevent resin from backing up into the catalyst
ow stream. Attached to the bottom of the Mix­Block is a solvent ush valve for quick ushing of only the mixed material from the Mix-Block out to
the applicator.
Attached to the outlet of the Mix-Block is the spiral mix tube. This is simply a piece of tubing with a
helical-shaped element inside the tube. This ele­ment causes the two materials (resin and catalyst) to be "folded" together numerous times as the
materials pass through it, thus causing it to mix.
The optional CCV style color valve stack allows users to do color changes on the resin side of up to 10 colors.

LN-9407-00.2
Ransburg
RCS-2 User Manual - Introduction
The solvent manifold supplies solvent for ushing
as well as lling of the magnetic coupling chamber.
The pump bypass valve is mounted on the resin
pump and allows the uid passing into the inlet
of the resin pump to bypass the gears and go
directly to the outlet port. This can decrease ush
and load times.
NOTE
> This valve should not be used while
loading 2k materials as improper ratios will result.
CHANNELS AND GUNS
The RCS-2 control system achieves closed-loop
control of its uids via its congured channels and guns. A channel consists of one pump, one motor,
one motor amplier, two pressure transducers,
and one half of a channel card. A gun, in most cases, represents one applicator
and may be congured with one channel (for ow control only) or congured with two channels (for ratio and ow control).
Each channel operates independently of and simultaneously with all of the other channels in the system. The controller, therefore, provides
accurate dynamic ow control for all channels.
CONTROL RACK INTEGRATION
The control rack has been designed to be con­sistent with other Ransburg products to allow integration of the RCS-2 control rack in larger control consoles. These consoles may house rotary atomizer speed control, shaping and fan air control, high voltage setpoints, etc.
CONFIGURABLE OPERATING PARAMETERS
The design of the system allows it to be congured
to meet the requirements of the application. The large number of parameters allows the system to
be used in almost any application involving ow and/or ratio control of uids.
System Parameters are parameters that affect the overall system, which includes all channels and guns or the user interface. They include:
• Over Pressure Limit
• Foldback Pressure
• Pressure Sensor Limit
• Horn Enable/Disable
• Password
• Password Timeout
• Controller I/P Address
• Interface Card Name
• Software and Firmware Version Information
• User Program IP Port
• System Time
• System Date
Gun Parameters are parameters that affect the gun. These parameters apply to all channels
congured to that gun. They include:
• Mode (manual or automatic)
• Number of channels congured to gun
• Master Channel Number
• Slave Channel Number
• Number of Applicators
• Default Job Number
• Mixed Volume
• Flow/Ratio Tolerance
• Tolerance Volume
• Alarm Tolerance Time
• Solvent Flow Meter Calibration Factor
• Horn Code
• Auto Reset Enable/Disable

SYSTEM GUIDELINES
Customized Prints
Drawings and information contained in this section of the manual is applicable to most installations. However, in many cases, will supply custom
installation drawings for your specic site. It is
highly recommended that if your installation differs
signicantly from the installation drawings supplied
by, you notify your representative to ensure that standard installation practices are not violated and
to have your prints updated to reect the installation
accurately for future reference.
Cable Assemblies
Interconnections between all control panels and the uid panels are made using custom manufac­tured cable assemblies with military style connec-
tors. This simplies installation and eliminates the
possibility of items being wired incorrectly. The
one exception to this is the discrete interface I/O
wiring. These connections will vary greatly from installation to installation. This can involve well over 100 connections per control console and, therefore, require that conduit be run to the control console and multiple cables or wires pulled from the control console to the controlling medium (PLC, robot, etc.).
There are four basic panels used in the RCS-2 system:
• Main Control Console
• Motor Amplier Panel
• Fluid Panel
• Remote Operator’s Panel
The motor amplier panels must be placed within 100-feet of the control console, the uid panels
must be placed within 10-feet of their respective
motor amplier panel, and the remote operator’s
panel must be placed within 25-feet of its respective
motor amplier panel. If longer distances than
this are necessary, contact your representative.
Fluid Regulators
It is highly recommended that a pilot operated
uid regulator (similar to the DR-1 regulator) be
used on the inlet of all of the gear pumps. The accuracy of the pumps depends to a high degree on controlling the differential pressure across the pump. The system includes pressure transducers
in the motor amplier panels to pilot these uid
regulators. In this way, the software has full con-
trol of uid inlet pressure of the pumps and can,
therefore, control the differential pressure across
each pump. By using this feature, the extremely accurate ow rates and ratios can be maintained,
without the need to calibrate the pumps.
Equipment Grounding
All panels should be grounded in accordance with either the National Electrical Code or local electri­cal codes (whichever is more stringent). Refer to the electrical installation drawings provided by to locate the grounding terminal for all control panels.
Equipment Locations
All of the panels must be located outside of the hazardous area with the exception of the intrinsi­cally safe version of the Remote Operator’s Panel
(and in some cases the uid panel). If in doubt,
refer to local codes and ordinances, or contact
your representative for clarication.
LN-9407-00.2
Intrinsic Safety
The motor amplier panels can be ordered with optional zener barriers that make the uid panels
and the remote operator panels intrinsically safe for operation inside hazardous areas. An optional
explosion-proof catalyst ow sensor and motors
are also available. They must be hard-piped if used in hazardous areas.

INPUT POWER
Input power supply connections should be made
from a fused disconnect. With the exception of
the stand alone, cart mounted RCS-2; conduit should be used for bringing the input power into
the control panel and motor amplier panels. In
the case of the stand alone unit, SO cord will be provided with standard AC grounded plugs.
Both the control panel and the motor amplier
panels operate from 120 VAC at 60 Hz with a
maximum current draw of 10 amps (for each panel). The uid panels get their power from the motor amplier panel and, therefore, require no
power connections.
If there is the possibility of AC line voltage uctu­ations of greater than ±10% of the line voltage, a constant voltage transformer (CVT) should be used between the fused disconnect and the control panel
and motor amplier panels. (These uctuations
are commonly seen when heavy electric machin­ery or welding equipment is being used nearby.)
Figure 8: Control Panel Input Power
Refer to Figures 8 and 9 to determine proper AC power and ground connections to the control panel
and the motor amplier panels.

DISCRETE CHANNEL AND GUN INPUTS
All discrete digital inputs are optically isolated and will function with an input voltage in the range of 10 VDC to 45 VDC. Factory jumper settings on the interface and channel boards require that voltage be sourced to the discrete input. If, how­ever, a sinking input is required, inputs can be
recongured by changing those jumpers. (See Appendix C for Channel Board Jumper Settings.)
It is recommended that the 24 VDC power supply in the controller be used to source these inputs
(terminal #1331). Optionally, if an external supply
If the gun is congured as a single channel gun
and this signal is pulsed, the gun will be put in
fast ll mode. This will cause the pump to run at its maximum rate (150 RPM) until the halt signal
is pulsed. (It is not necessary to have the trigger signal energized.)
NOTE
> Times stated above are for discrete
digital inputs only. When interfacing us­ing Bradley's Remot I/O (aka RIO), these
times may vary signicantly. (Refer to the
RCS-2 RIO Interface Programmer's Man­ual for more details.)
pulsed signals to a gun should also be separated
by 250 milliseconds. For example, don't turn the
halt/reset signal off at the same time that the run signal is being turned on as results will be unpre­dictable. Maintained signals operate as long as the input remains energized.
Figure 10: Gun I-O Sourcing-Sinking
is used as the source for these inputs, it must be referenced to the ground terminal (terminal #1113). There are two types of discrete digital inputs, pulsed inputs and maintained inputs. The pulsed inputs must be turned on and held on for 250 mil­liseconds minimum, to insure operation. Multiple
Some discrete digital inputs are specic to a gun and others are specic for a channel. If it is a gun input and the gun is congured as a two channel gun, eld wiring must always be connected to the
master channel terminals (channel A).
Fast Fill
Type of Input: Gun Type of Signal: Pulsed The gun must be in run mode prior to initiating this mode or the RCS-2 controller will ignore it.
If the gun is congured at a two-channel gun, and
this input is pulsed, the gun will be placed in fast
ll mode. The pumps will run at the maximum
speed possible while maintaining the target ratio. That is, the software will determine which of the
two pumps can be run at its maximum speed (150
RPM) and run the opposite channel at whatever speed is necessary to ensure the proper ratio of component A to component B. The software
LN-9407-00.2
18
RCS-2 User Manual - Installation
Ransburg
determines this based on the programmed pump sizes and the programmed ratio. Pulsing the halt/
reset input takes the gun out of the fast ll mode.
Channel Fill
Type of Input: Channel Type of Signal: Pulsed A gun must be in the ready state to use this mode.
This mode functions the same for single channel guns as it does for dual channel guns.
When this input is pulsed, the pump for that channel
is run at its maximum rate (150 RPM) until the halt
signal is pulsed. It is not necessary for the trigger input to be energized. If it is desired to have both channels of a two channel gun run at full speed
(for ushing, etc.) this input must be pulsed on both channels. The halt signal for the specic channel that is channel lling must be pulsed. For example: if both channels are channel lling, both
halt signals must be pulsed to stop them.
Feather Set
Type of Input: Gun Type of Signal: Pulsed
If the gun is congured as a manual mode gun and
the value zero (0) is programmed in for feather pressure (under the CONFIG JOB parameters) this input can be used to program the feather
pressure "on the y". That is, if a handsprayer is
painting and this input is momentarily energized, the RCS-2 controller takes a snapshot of the out­bound pressure of the pumps (or the pressure at the optional feather pressure sensor, if it is being used) and then starts controlling the speed of the pumps to maintain that pressure. The optional Remote Operator’s Panel has a pushbutton on it that allows the handsprayer to utilize this fea-
ture. (Refer to "Appendix H" for more details on
feathering.)
Run
Type of Input: Gun Type of Signal: Pulsed
This signal takes a congured gun from the ready
state to the "run" mode. In order for a gun to spray,
it must rst be put into run mode. It is essentially
a way of enabling a gun. Energizing the trigger
input of a gun will not cause uid to ow unless the gun has rst been placed in run mode.
Halt/Fault Reset
Type of Input: Gun Type of Signal: Pulsed
This input takes a congured gun that is in run
mode to the ready state, essentially disabling the gun from spraying. It also resets a fault for the gun if it is in the faulted state.
Trigger 1
Type of Input: Gun
Type of Signal: Maintained This input tells the controller to run the pumps if and
only if the gun has rst been placed in run mode.
Motor Amp Enable Type of Input: Channel
Type of Signal: Maintained This is an input to the controller from the motor
amplier indicating that the motor amplier has
been enabled by the channel card and that there are no problems.
Triggers 2, 3, and 4
Type of Input: Gun
Type of Signal: Maintained These signals are additional trigger input signals. They would be used in cases where the output of a uid panel was split between multiple applica­tors. They work in conjunction with the trigger 1 input to allow up to 4 independent triggers, one for each of 4 applicators. The software can be
congured in such a way that if one of these inputs is on, the uid panel delivers the target ow rate
of material. If a second input is turned on, then
the uid panel will deliver twice the target ow
rate. If a third input is energized, three times the
target ow is delivered and if all four inputs are energized, the uid panel will deliver four times the target ow rate. It is assumed that each of these
inputs are also connected to the trigger inputs on four independent applicators.

Volume Fill
Type of input: Gun Type of signal: Pulsed
By pulsing the volume ll discrete input, the unit
will be put into the V. FILL mode. (The gun must be in the ready state prior to this.) When the gun trigger input goes high, the pumps will run
at the programmed ow rate and ratio until the
volume programmed in for Fill Volume (on the Job parameters screen) is dispensed. If more than one gun trigger inputs goes high (triggers 2,
3, or 4) the unit will multiply the ow rate by the
number of high inputs but still only run until the programmed volume is dispensed. When that volume is reached, the gun will be halted and returned to the ready state.
Volume Fill with Fast Fill Mode
It is possible to volume ll and fast ll simultane­ously. If the gun is put into volume ll mode, and then the fast ll input is pulsed, the unit will run in fast ll mode until the volume programmed in for ll volume is dispensed. At that time, the gun will
be halted and returned to the ready state. This happens regardless of the condition of the gun trigger inputs.
to a dry contact relay with allowable current limited
to 1 amp 45 volts, AC or DC (exceeding this limit
may damage the output on the channel card). Although a myriad of voltages could be used, it is recommended that the Hi signal be connected to the +24 VDC terminal (terminal #1331) and the output be taken from the Lo output terminal. This terminal will supply 24 VDC when the output is energized by the software. (Referenced ground terminal is #1113.)
An alternate way of connecting these outputs would be to connect the positive supply voltage to the load, the common of the load to the Hi output terminal of the RCS-2 output, and connect the Lo output terminal to both the ground of the supply connected to the load and the ground terminal (terminal #1113). Once again, current must be
limited to 1 amp and should never exceed 40 volts.
Push Out
Type of Input: Gun
Type of signal: Pulsed This feature allows a customer that uses dual purge applicators to use two resin pumps that share a common catalyst pump and pushout the resin with solvent on one side of the dual purge applicator while loading the other side of the applicator with
the next material to be sprayed. For additional
details on how to implement this feature, refer to"
Appendix L".
DISCRETE CHANNEL AND GUN OUTPUTS
All discrete outputs have two terminals, one labeled Hi and one labeled Lo. They operate very similar

Fault
This output is energized anytime a fault condition is recognized by the software. Even if the fault
is disabled (turned off) on the Congured Alarms
screen, this output will be energized as long as
the condition persists. Fluid ow will not be halted when this output is energized unless it is con-g­ured to do so on the Congured Alarms screen.
Ready
This output is energized if the gun is congured
properly, a good job number has been loaded, and the gun has been placed in run mode. This output goes off if a fault occurs.
Spray Shutdown
This output is energized if a fault condition exists and the specic fault that exists is enabled on the Congured Alarms screen (turned on). This indicates that the ow of uid from the uid panel
has been stopped as the result of a detected fault condition.
Flush Request
This output is energized when the pot-life timer
has expired from the mixed material. (For more information, see "Mixed Volume and Pot-Life
Timer" in the "Operation" section.)
Motor On
This output is energized by the software when it wants to control the motor. It is connected to the
input of the motor amplier that causes the motor to be controlled. Do not connect external devices
to this terminal.
Motor Amp Reset
This output is energized by the software when it
is necessary to reset a faulted motor amplier.
Typically, by pushing the Clear Faults button on the front panel or by pulsing the Halt/Reset digital input, this output will be energized momentarily
to reset the amplier. Do not connect external
devices to this terminal.
ANALOG INPUTS
Analog inputs are jumper selectable to be 0 to 10
VDC or 4-20 mA with the exception of the hardener ow sensor which is xed at 4-20 mA.
Hardener Flow
Type of Input: Channel Type of Signal: Fixed at 4-20 mA Factory Setting: Not applicable This is a 4-20 mA input that is normally connect-
ed to the output of a thermal shedding type ow sensor placed in the catalyst uid stream. Since
the feedback from the motor tachometer can only
indicate that the motor is turning and not that uid is actually owing, this optional sensor is added to prevent spraying uid without any catalyst.
Flow Rate
Type of input: Gun Type of signal: Jumper Selectable Factory Setting: 0-10 VDC This input is used if it is desired to have the ability to
vary the ow rate as the unit is spraying. Minimum and maximum ow rates are programmed and an external device (robot, PLC, potentiometer, etc.) controls the actual ow rate by varying the input
between 0 and 10 volts or 4 and 20 milliamps.
(See "Minimum Flow and Maximum Flow in the
"Operation" section.)
Feather Pressure
Type of Input: Gun Type of Signal: Jumper Selectable Factory Setting: 4-20 mA This input allows an optional pressure sensor to be placed near the spraygun. Handgun operators can use this to program a set feather pressure at the inlet of the spraygun and the RCS-2 will maintain that pressure while spraying.

RCS-2 User Manual - Installation
Pump Inlet Pressure
Type of Input: Channel Type of Signal: Jumper Selectable Factory Setting: 4-20 mA This input is typically connected to a pressure sensor located near the input of the pump. When
used in conjunction with a pilot operated uid
regulator on the inlet of the pump, it minimizes the differential pressure across the pump, thereby increasing the accuracy of the pump.
Pump Outlet Pressure
Type of Input: Channel Type of Signal: Jumper Selectable Factory Setting: 4-20 mA This input is typically connected to a pressure sensor located near the output of the pump. This is used to monitor and control the differential pressure across the pump, thereby increasing the accuracy of the pump.
This outlet pressure is also used as the feather pressure for manual spray guns if an optional feather pressure sensor is not used.
ANALOG OUTPUTS
Most of the analog outputs are jumper selectable to be 0 to 10 VDC or 4-20 mA. Actual Flow, how-
ever, is xed at 0-10 VDC.
Motor Speed
Type of Output: Channel Type of Signal: Jumper Selectable Factory Setting: 0-10 VDC This output is connected to the analog input on the servo motor controller located in the motor
amplier panel. A 0 VDC signal tells the servo
controller to run at 0 RPM, a 10 VDC signal tells
it to run at the programmed maximum RPM for
that pump.
Pressure Control Type of Output: Channel
Type of Signal: Jumper Selectable Factory Setting: 0-10 VDC This output is normally connected a voltage to pressure transducer which converts a 0 to 10 VDC signal to a 0 to100 psi air pressure. The pressure is then used to control the pilot port on
a uid regulator. This uid regulator is then used to control the uid inlet pressure of the pump.
Actual Flow
Type of Output: Gun Type of Signal: 0-10 VDC This output is 0 to 10 VDC output that is propor-
tional to the actual ow of material coming out of the applicator. 0 VDC means no ow and 10
VDC indicates 2000 cc/min. (Therefore, 3.40 VDC would indicate 680 cc/min.)
FREQUENCY INPUTS
All frequency inputs are optically isolated and
expect a maximum amplitude square wave of 24 VDC and a maximum frequency of 1.5 KHz.
Both sides of the optical isolators are accessible, allowing the RCS-2 to sink or source any of the frequency signals.
Motor Feedback
Type of Output: Channel Type of Signal: Frequency This signal is a square wave output from the servo motor controller, indicating the actual speed of the motor that is driving the pump. It is used by the
rmware to determine the current ow rate of the
material out of the pump. (It can alternately be
connected to the output of a ow meter placed in the uid stream.)
Solvent Flowmeter
Type of Output: Gun Type of Signal: Frequency
This input allows users to connect a owmeter
in the solvent supply line and collect totalization data on solvent usage.
