J CORRECT USE
Adjustment (E8CC)
1. Set the mode selector to SET. 3. Set the mode selector to RUN.
E8CB/E8CC
2. Turn the pressure adjuster to the desired pressure.
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.

Displays the ON-point pressure within the permissible range Positive Pressure: Indicates that the imposed pressure is lower than the permissible range. Negative Pressure: Indicates that the imposed pressure is higher than the permissible range. The E8CC is in normal output operation in both cases. SET Abnormal pressure setting Positive Pressure: Indicates that ON-point pressure value is lower than the permissible range. Negative Pressure: Indicates that ON-point pressure is higher than the permissible range.

overcurrent Element destruction
Indicates that the output transistor has excessive load current. The result is that the output of the E8CC is turned OFF. This display flashes until the condition returns to normal. Check the output OFF normal wiring if this display flashes. Indicates that the Pressure Sensor element is damaged due to the imposition of excessive pressure or for other reasons, in which case the output of the E8CC turns OFF. If this display appears, the reasons OFF appears E8CC can no longer be used.

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. Apply a flat-blade screwdriver to the rear hook. Then the Pressure Sensor can be removed easily.
Removing
DIN-rail mounting bracket (provided with each model)
J WIRING
Pressure port
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.
