If the actuator hunts or responds
unnecessarily to a fluctuating set point
signal the deadband must be increased.
If more accurate control is required the
deadband may be decreased.
Use the + or - key to select the
deadband width. Range 00–99
corresponds to 0–9.9% of setpoint
signal.
NOTE: Maximum deadband is 9.9% of
valve stroke. Normally minimum
deadband should not be less than 1%.
The motion inhibit timer introduces a
delay in the actuator response to a
rapidly fluctuating set point signal,
preventing unnecessary movement.
Once the system stabilises the actuator
will respond to steady changes in the
set point signal as necessary.
Use + or - key to adjust motion inhibit
time in seconds: range 0–99. Normally
it is recommended that motion inhibit
time should not be set to less than 5
seconds (refer to note on page 62).
Use + or - key to enable [On] or disable
[OF] action on loss of set point signal.
[On] – Failsafe as determined by [FF].
[OF] – Failsafe to position
corresponding to low set point.
Failsafe action when [FA] enabled.
Use + or - key to select, on loss of set
point signal:
[Lo] – move valve to position
corresponding to minimum set
point.
[SP] – stayput on loss of set point.
[Hl] – move valve to position
corresponding to maximum set
point.
