Tight Shut Off Threshold Close
This box indicates the highest level analogue mA setpoint as
a percentage that will fully close (tight shut off) the valve.
The example shown in Fig 42.2 states that a 0.5% or lower
control request will give a tight shut off (closed) on the valve
Tight Shut Off Threshold Open
This box indicates the lowest level analogue mA setpoint as
a percentage that will fully open the valve.
The example shown in Fig 42.2 states that a 99.5% or greater
control request will give a tight shut off (open) on the valve.
Obstruction Back off
If enabled the actuator will back off the movement if the
maximum torque is exceeded during travel. The actuator will
make 3 attempts to back off and return to the setpoint.
If disabled the actuator will remain stationary until a
request to move in the opposite direction is received or the
obstruction is removed.
Back off Distance
The distance the actuator backs off can be selected on the
drop down menu as shown.
Back off Time
Can be set to a maximum of 5 seconds before back off is
executed.
