Remote Bank Function
The remote bank input signal allows the setting of two kinds of sensitivity adjustment values.
Brown +V
Black; control output
Orange; self-diagnosis

Purple
Bank 1: SW = OFF
Bank 2: SW = ON
Blue 0 V
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.

ON Unstable
Sensing operation is not stable be-
cause zone B is within the hystere-
sis differential range.

Unstable OFF
Reduce the sensitivity of the E3X with
the sensitivity adjuster and turn off
zone B.

ON
OFF
Reduce the hysteresis value with the
hysteresis adjuster so that zone A will
be ON.
