VT Valve Time (0 to 100%)
– Enter the time in seconds that it takes for the VT Valve to move from the fully closed
position to the fully open position. This can be timed by using the controller manual Valve Manual override feature and
driving the valve to the fully closed position (0%). When the actuator has stopped, enter the override value to be 100%
and start timing the actuator. When the actuator stops moving note the time taken and enter it into the VT Valve time
parameter. Alternatively some actuators will state the running speed for the distance to be travelled in there literature.
If there is no VT Valve fitted then the setting can be ignored.
