Stay-put position
Tune the 12mA output when only one AO is used. Used for proportional valves that has a spool
which is out of the center.
Adjustment is done in the following way:
1. First test by setting the valve to 50% and monitoring it for about 2 minutes. If it stays at 50%
everything is OK.
2. If the valve drifts towards open, the stay-put value is reduced by 0.1 mA at a time until the
valve remains at 50% without movement.
3. If the valve drifts towards closing, the stay-put value is increased by 0.1 mA at a time until
the valve remains at 50% without movement.
Fail position and fail position 2

• 4mA
• 12mA (Default)
• 20mA
