Distech Controls SC-EP Series Installation Manual

SC-EP Series

Product Description

The electronic to pneumatic transducer converts an electical input signal to a pneumatic output signal to position pneumat-
ic damper and valve actuators in HVAC systems. The transducer provides a linear 3-15 PSI output in response to a 4-20
mA, 0-10 Vdc or PWM input.

General Installation Recommendations

Disconnect the power supply before installation and do not exceed device ratings.
Make all connections in accordance with the wiring diagram and electrical codes.

Particles in the air supply larger than 0.03 microns may adversely affect the reliability and life of the transducer.

A SC-EPAF in line air filter is recommended for installation between the main air supply and the main air port of the de-

vice.
A refrigerated air dryer, particulate filter and coalescing filter should provide a quality air supply.

Compressor oil must be non-paraffin mineral base of naphtha base. Synthetic base oils will destroy pneumatic controls

and void the warranty.
Do not locate the unit in areas subject to incidental contact, vibration, severe mechanical shock, excessive moisture,

or corrosive fumes.
The transducers must be mounted within 5° of the upright position. See the "UP" arrow on the PCB or label.
