MODES
In addition to displaying measurement values, the E8F2 has a variety of functions. These functions are available in four main modes as
described below: Measurement Mode, Basic Setting Mode, Pressure Setting Mode, Special Setting Mode. Three functions are available
in measurement mode. For the relationships among each mode and for switching methods, refer to the following figure.

The E8F2 provides output according to the measured values to control external devices, such as valves and pumps. In order to control
the external devices, a reference value can be set so that the output will be ON or OFF if the measured values are above or below the
reference value. The output ON- and OFF-point settings are described below, provided that the output is normally open.
Note: The ON and OFF points are set in pressure setting mode manually or through auto-teaching.

Precautions
J
ENVIRONMENT
Do not use the Sensor in locations subject to explosive or
flammable gases.
Do not use the Sensor in an environment subject to corrosive
or combustible gases.
Make sure that the Sensor is free of water.
J
AVOID DAMAGE TO THE E8F2
Do not impose any voltage exceeding the rated voltage on
the E8F2.
Do not short-circuit the load connected to the E8F2.
When supplying power to the E8F2, make sure that the po-
larity of the power is correct.
J
WIRING
Do not wire power lines or high-tension lines adjacent to the
lines of the E8F2.
If no linear output is used, cut the gray lead wire short and
apply insulating tape to the lead wire so that it will not come
into contact with any other terminal.
J
MOUNTING
Mount the Sensor so that ultrasonic vibrations will not be
applied directly to the Sensor.
Do not insert any wire into the pressure port. Doing so may
damage the pressure elements and cause a malfunction.
Do not apply a tensile strength in excess of 50 N (11.25 lbs)
to the cords or connectors.
The pressure-introducing section (aluminum die-cast made)
is fixed with tapered 1/8 NPT male screws and M5 female
screws. When using tapered screws, use tapered 1/8 NPT
female screws.
Wrap the tapered 1/8 NPT male screws with sealing tape to
prevent any leakage. Tighten the male screws to a torque of
10 NSm (7.38 ftSlbs) max.
Tighten M5 female screws to a torque of 2 NSm
(1.48 ftSlbs) max.
Tightening each male screw by using a 12-mm wrench to
hold its hexagonal head, not the screw itself.
Hexagonal head
E8F2
When attaching the Mounting Bracket to the Sensor, make
sure that each M3 screw is tightened to a torque of
0.5 NSm (0.37 ftSlbs) max.
