These screens show 8 values of torque for the actuator travelling in the opening or closing direction.
They are the values that have been most recently received from the field unit. The 8 values refer to the
actuator motor torque at the following positions of the actuators stroke, 6%, 19%, 31%, 44%, 56%,
69%, 81% and 94%. Thus on the "Open Torque" example screen shown above, 101% is the torque
value at 6% open, 83% is the torque value at 19% open, etc.
Torque values are displayed as percent of rated torque and have a range of 0 to 120%.
If the IQ field unit has been programmed with a torque filter factor of “000” then these 8 torque values
are automatically returned to the master station once the actuator has travelled from one end of travel
to the other. However, if the filter factor has been set to a value greater than “000” these values are
only returned when the reload button (2) is pressed. Pressing reload will also cause the master station
to fetch the torque values when the actuator has not travelled from end to end, irrespective of filter
factor setting. If the actuator is not an IQ, but uses an IQ actuator field unit these pages will appear,
but will not be populated with data.

Note: If the actuator has been moved over part of its stroke, e.g. from 20% to 60% open,
then the torque values outside that range may have been reset to zero.
