oPeration

The EP2 electropneumatic pressure transducer uses micro-controlled poppet valve technology for highly accurate pressure sensing. The poppet valves consume no air, eliminating unnecessar y air losses in the system and allowing for stable and reliable operation. The EP2 is comes installed on standard SnapTrack, and an optional cover is available to protect from dust and other environmental factors. An LCD display and LED indicators make it easy to read system status at a glance.

installation

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

1. Mount the transducer using the screws provided. Avoid damaging the electronic components.

2. Wire the transducer and congure the jumpers for desired operation as shown in the Wiring and Conguration section on the following page.

4. Attach pressure tubing to the hose barbs. Observe MAIN and BRANCH port labels. Use exible ¼” O.D. poly tubing for the main and branch pneumatic connections.

Main supply pressure must not exceed 45 psig.
