CORRECT USE
Adjustment (E8CC)
1. Set the mode selector to SET.
2. Turn the pressure adjuster to the desired pressure.
Screwdriver
0
--76
3. Set the mode selector to RUN.
The E8CC has normal output in the SET mode. Changing the
pressure setting is possible in RUN mode by turning the pressure
adjuster. Do not turn the pressure adjuster after it has been set to
the desired pressure.

Precautions
J
MOUNTING
Diaphragm
If the diaphragm is damaged, the Pressure Sensor will not
operate correctly. Do not insert a screwdriver or steel wire into
the pressure port.
The pressure port has an NPT 1/8 taper screw and M5 female
screw. Apply sealing tape around the female taper screw so that
no pressure leakage will occur.
Make sure that the tightening torque of the M5 female screw is
3.9 N S m (2.87 ft lbs) or less.
If the Pressure Sensor is directly connected to a conduit, be sure
to apply a wrench to the pressure port, not to the plastic case.

J
DIN-RAIL MOUNTING BRACKET (E8CC)
Mounting
Fit the front part onto the bracket.
Press the rear part onto the bracket.
Removing
Apply a flat-blade screwdriver to the rear hook. Then the
Pressure Sensor can be removed easily.
DIN-rail mounting bracket (provided with each model)
J
WIRING
If no linear output is used, cut off the black lead wire and apply
insulation tape to the lead wire so that it will not come in contact
with any other terminal.
