J) Deadband Dial

The deadband adjusts the limits of the valve’s
deviation between an actual position and a target
position. The dead band is set to 0.12mA DC
max.

Deadband indicates the extent of the reaction on
the input signal.

Low deadband setting may cause the actuator
to hunt or to unnecessarily respond to a
fluctuating input signal. If so, the deadband must
be increased.

Turning the Deadband Dial in clockwise direction
will increase the resolution (Range 0.0625mA to
1mA).
