E3X

Power supply

OFF

Remote tuning input

Sensitivity setting

T1: 0.5 to 3 s

T2: 0.5 to 1 s min.

Maximum sensitivity

T2: 5 s min.

Remote Bank Function

The remote bank input signal allows the setting of two kinds of sensitivity adjustment values.

To set two kinds of sensitivity adjustment values, the

purple and blue wires must be connected with each oth-

er and select bank 2 to tune the E3X.

Bank 1: SW = OFF

Bank 2: SW = ON

Variable Hysteresis Function (E3X-H11)

Sensing of Plate Level Differences

(If sensing is impossible with the hysteresis value set to maximum)

Refer to the following when using the hysteresis adjuster.

Sensing operation is not stable be-

cause zone B is within the hystere-

sis differential range.

Reduce the sensitivity of the E3X with

the sensitivity adjuster and turn off

zone B.

Reduce the hysteresis value with the

hysteresis adjuster so that zone A will

be ON.
