Hardware Configuration
Reference "Addendum A" in the "Appendix" sec-
tion for board level hardware settings. For new
system installations, all hardware settings should
already be in the correct positions. However, if
replacing any electronic board assembly, verify
that the settings of the new board are identical to
those of the board being replaced. In the event
that the replacement board is a newer revision
and does not appear identical, refer to any docu-
mentation that was supplied with the board, or
contact your Ransburg representative or contact
Ransburg service.
Transducers
The transducers convert electrical control signals
from the fluid flow controller to the air pressure
signals used to operate the material regulators.
The transducers can be either current controlled
(4-20 ma) or voltage controlled (0-10 VDC). The
transducers can be mounted separately or collec-
tively depending on the installation requirements.
Make sure that the Channel Module jumper set-
tings match the type of transducer being used
(refer to "Channel Module Mother Board Jumper
Settings Channel 1 I/O and Channel 2 I/O" in the
"Appendix" section).
The electrical-to-pneumatic (E/P) transducers are
supplied as separate sub-assemblies or as part
of a standard transducer panel. The transducer
panel offers a convenient way to mount transduc-
ers for 2K applications. There are typically two
transducers located in each panel with electrical
terminals and an air supply input.
The transducers may also be mounted individually
on any air drop outside of the Class 1, Division 1
hazardous location if:
1. Tubing and cable lengths do not violate the
minimum and maximum lengths specified in the
"Installation" section of this manual under
Equipment Locations".
2. The air supply meets the specifications as
listed in the "Introduction" section of this manual
under "Pneumatic Specifications" or those pub-
lished with the transducer.
A 1:1 volume booster may also be connected
directly to the transducer output when; operating
a DR-1 TM Fluid Regulator, if pilot line lengths are
longer than recommended, or of a larger tubing
diameter is used other than that recommended.
Keep the distance between the transducer to the
material regulator as short as possible, without
violating the minimum lengths specified, to avoid
system response delays and to achieve the op-
timum fluid flow characteristics for the system.
Material Regulators and
Flow Meters
The location and mounting of the material regula-
tors and flow meters is specific to each installa-
tion. The information presented here is intended
as a guideline only. Reference should be made
to the supplied documentation specific to your
installation.
Fluid Supply Requirements
• The fluid supply must be free of pulsation
and surges.
• A fluid strainer/filter must be installed im-
mediately before the material regulators. The
elment size of the strainer should be 100
mesh or per the recommendation of your
Ransburg representative.
• For Two-Component (2K) Systems: Selector
valves are required for calibration or verify-
ing of the flow meters and should be mount-
ed close to the mixing block. These are sup-
plied as part of the standard fluid panel.
Drawings created specifically for your sys-
tem will provide detailed information about
valve type and location. Mount the calibra-
tion valves in an easily accessible area close
to the mixing block. For most applications
the flow meter and material regulator are
mounted as an assembly as close as possible
to the mixing block and calibration valves.
• For systems with fast trigger cycles that
utilize weepless MVR valves, or where
dynamic control of fluid flow rates (different
flow rate during a JOB), consider installing
trigger valves (typically color control valves)
immediately upstream of the MVR valves so
that the CHANNELs may be placed in
