12.4 How to test factory settings (with positioner)?

1. Using 4-20mA input to drive clockwise the actuator to the end
position.
2. According to the situation:

If end position cam trips the switch at the same time as
pump flow is stop, you do not need to resume settings.

If end position cam trips the switch before the pump flow
is stopped, set the cam slightly counter-clockwise to
get the switch tripped and the valve closed at the same
time

If the pump flow is stopped before cam is tripped, set the
cam slightly clockwise to get switch tripped and pump
flow stopped at the same time
3. If wired and if necessary, set the clockwise signaling cam
accordingly.
4. Using 4-20mA input to drive the actuator counter-clockwise to
the end position.
5. Proceed to the same checks as in pt.2 with the opposite
directions.
6. If wired and if necessary, set the counter-clockwise signaling
cam accordingly.
