CALIBRATION
All electropneumatic transducers are factory calibrated to
meet or exceed published specifications. If field adjustment is
necessary, follow these instructions:
1. Connect air to the Main port.
2. Connect an accurate gauge to the Branch port using a
minimum of 6 to 10 feet (1.8 to 3.0 m) of tubing.
3. Connect an 18 to 28 VAC or VDC power source to the
[+] and [-] terminals. The maximum supply voltage
should not exceed 30
4. Apply a low input signal to the [-] and [I] terminals (0
or 4 MA).

5. Adjust [Z] to obtain the desired low output pressure.
6. Apply a high input signal to the [-] and [I] terminals (5/

7. Adjust [S] to obtain the desired high output pressure.
8. Repeat steps 4 through 7 until the transducer is fully
calibrated.

INSTALLATION PRECAUTIONS
Do not use on an oxygen service, in an explosive or
hazardous environment, or with flammable or combustible
material.
Disconnect the power supply before installing the transducer.
Failure to do so can result in electrical shock and equipment
damage.
Make all connections in accordance with the job wiring
diagram and national and local electrical codes. Use only
copper conductors.
Use electrostatic discharge precautions such as wrist straps
when installing and wiring the transducer.
Do not exceed ratings for the transducer.
This transducer contains a half-wave rectifier power supply
and must not be powered fro m transforme rs powering other
devices with non-isolated full-wave rectifier power supplies.
Verify that the main supply pressure does not exceed 40
Ensure a minimum of 6 to 10 feet (1.8 to 3.0 m) of tubing
between the transducer and the actuator.

MOUNTING
The electropneumatic transducer must be mounted in an
upright posi tion so that th e main and bra nch ports face
upwards and the gauge can be read easily.
1. Select the mounting location.
2. Mount the transducer on a vertical surface with three
#8 self-tapping screws (not provided).
.
CHECKOUT
To verify proper operation of the transducer, adjust the input
signal to obtain a maximum output pressure for the
appropriate range. The output should be 15 or 20
adjust the input signal to obtain a minimum output pressure.
The output sho uld be 0 or 3
