Approach Band 1
[0.1 to 3.0 proportional bands]
This parameter limits when derivative action time 1 is applied. When
the process variable is outside the approach band, derivative action
is not applied.
Manual Reset Value 1
The value applied to bring the master control output to the zero
error point under normal load conditions (integral action
disabled) or the offset applied to the control output (integral
action enabled).
[0.0 to 100%]
Note. Manual reset is applied whether or not an integral
action time is set.
Control Deadband
When the process variable is in the deadband, changes to the
control output due to proportional and integral action are
suppressed. When a cascade template is selected, the control
deadband is applied to the master output only.
[In engineering units or 'OFF']

…3.2 Level 2 – Tune
•1 Not displayed if the associated derivative action time is set to OFF.
•2 If manual control is selected and no integral action time is set, the manual reset value is
calculated automatically to give bumpless transfer into auto control.
