4.12.6 Proportional Band
Proportional band is the range of errors between position and demand signal that will produce reduced speed (pulsing).
Default = 15%
To change from the default, select “NO” until the required value is displayed. The value is adjustable between 1% and
100%, in 1% increments.
4.12.7 Deadband
Default = 2%
The deadband should be wide enough to prevent “hunting” of the actuator but as low as possible to give adequate
response to changes in the error signal.
To Change from the Default Range:
Select “NO” to adjust the value between 1% and 50%, in 1% increments to suit the application.
