INTERFACE SERIES
Installation & Operation Instructions
EFP2, EFP2FS

GENERAL INFORMATION

The EFP2 converts a oating point signal into a
proportional pneumatic signal ranging from
0-20 psig. The pneumatic output is proportional
to the signal input. The EFP2 has a manual
override switch with terminal strip contacts to
indicate its status and a potentiometer to vary
the pneumatic output. Two LEDs indicate UP or
DOWN excursions, with an additional one for
power indication. The EFP2 o ers four jumper
selectable rates of change in the output
pressure. Output pressure ranges are jumper
shunt selectable for 0 to 10, 0 to 15 and 0 to 20
psig, and adjustable in all ranges. A 0-5 VDC
feedback signal, indicating the resultant branch
line pressure, is also provided. This signal varies
linearly with the branch pressure range selected.
It is designed with electrical terminals on one
end and pneumatic connections on the other,
allowing for maximum convenience in wiring
and tubing installation when panel mounted.
The EFP2 incorporates two valves (one controls
exhaust) and does not bleed air at set point. Its
branch exhaust ow and response time are not
limited by an internal restrictor and are similar to its
load rate. If power fails to the EFP2, branch line
pressure remains constant if the branch line does
not leak air. The EFP2FS is a two valve fail safe model.
Its three-way branch exhaust valve allows exhaust of
branch line air on a power failure.

MOUNTING INSTRUCTIONS

Circuit board may be mounted in any position. If
circuit board slides out of snap track, a
non-conductive "stop" may be required. Use only
ngers to remove board from snap track. Slide
out of snap track or push against side of snap
track and lift that side of the circuit board to
remove. Do not flex board or use tools.
