Troubleshooting
If it is suspected that the positioner is not operat-
ing correctly, check
the following :
1. Is the Cam in the proper orientation for your
application ? (See page 5).
2 Is the positioner properly mounted ? (See page
3).
3. Is the coupling or NAMUR shaft in proper
alignment with the Positioner Cam shaft and
actuator ?
4. Is the positioner piped correctly ? (See page 3
and 4).
5. Make sure supply pressure exceeds minimum
pressure required to move the actuator.
6. Is there instrument and output pressure at the
Positioner ? (If the Positioner is equipped with
a Gauge Block, check the instrument and
output pressure readings. If the positioner is
not equipped with a Gauge Block, connect
gauges to the instrument and output ports and
note readings.)
7. Is the actuator working properly ? (Disconnect
the supply pressure from the Positioner and
connect the supply pressure to the actuator.
Does the actuator move full stroke ?)

o-matic office or representative, (see back page).
