Trane 4190 1097 User manual

Electropneumatic Transducer
The Electropneumatic Transducer incorporates
quiet low wattage poppet valves and a pressure
sensor to measure and adjust the branch line
pressure proportional to its field selectable
input. A pressure gauge provides a readout for
the branch line pressure.
Required power for the Electropneumatic Transducer
is 24 VAC or 24 VDC. The transducer is designed for
mounting on a flat surface. Dimensions are
3¼”x3
1/8” x 3” (83m x 79mm x 76mm). See figure 1.
Before installation, check to see if you received the
correct transducer. Verify ordering # 4190 1097, range
of 3 to 15 psig and pneumatic control application.

Location
Proper location of the transducer is important to
ensure accurate measurement of pressure.

IMPORTANT! Avoid locating the transducer
in places having excessive vibration.
Mounting
The Electropneumatic Transducer’s steel
chassis design makes installation directly in a
control panel or with a snap track easy.
➊Position the transducer on a flat mounting
surface. Make sure the override buttons
and pressure gauge are accessible.
➋Mark the centers of the mounting holes.
➌At each of the marked locations, drill
holes for the mounting screws.
➍Mount the transducer to the surface with
the mounting screws.
Wiring
Air Connections
When connecting the main air supply, connect
transducer lines to clean air.
➊Connect the main air supply to the barbed
¼” (.0063m) brass connector labeled Main.
Pressure should not exceed 35 psig.
➋Connect the output air to the barbed ¼”
(.0063m) brass connector labeled
Branch. There should be a minimum of 6
to 10 feet (1.8m to 3.05m) of tubing
between the transducer and actuator.

➌When connecting the tubing, push in a
clockwise twisting motion. This helps you
to avoid loosening the barb fitting.
➍Make sure there are no kinks in the tubing.
Input Configuration
Select the input configuration using figure 2. The
transducer is configured for 4 to 20 mA input. To
change the input configuration, configure the
shorting plugs as shown in figure 2.
Power Connections
Universal 24 VAC/24 VDC supply voltage and
field selectable inputs ensure one unit
compatibility to most of the systems.
➊Follow the wiring diagram in figure 3.
Check wiring before applying power.
➋Select input configuration before
applying power.
➌Do not reverse polarity.
➍When using more than one transducer with the
same power source, polarity must be observed.
Note: Analog output wire must be 18 or 22 gauge
shielded twisted pair (equivalent to Trane BASD
wire #400 2028). Cut back and tape the shield at
the transducer.
The gauge on the transducer is for indication
only. The unit’s calibration is far more accurate
than the accuracy of the gauge.
Manual Override
The Electropneumatic Transducer has the
capability to operate in manual or auto
configuration. The default factory setting is to
the auto position. The output pressure is based
on the input signal supplied to the transducer
when configured to auto. In the manual
position, the transducer increases or decreases
output pressure based on the settings of the
override buttons as shown in figure 4.
