Wiring And Grounding Guidelines - Flowserve Logix 3200MD Installation, Operation And Maintenance Manual

Air-to-open and air-to-close are determined by the actuator tubing,
not the software. When air action selection is made during con-
figuration, that selection tells the control which way the actuator
has been tubed. The top output port is called Output 1. It should be
tubed to the side of the actuator that must receive air to begin the
correct action on increasing signal. Verify that tubing is correct prior
to a stroke calibration. Proper tubing orientation is critical for the
positioner to function correctly and have the proper failure mode.
Refer to Figure 1 and follow the instructions below:
Linear Double-acting Actuators
For a linear air-to-open actuator, the Output 1 port of the
positioner manifold is tubed to the bottom side of the actuator.
The Output 2 port of the positioner manifold is tubed to the top
side of the actuator. For a linear air-to-close actuator the above
configuration is reversed.
Rotary Double-acting Actuators
For a rotary actuator, the Output 1 port of the positioner manifold
is tubed to the bottom side of the actuator. The Output 2 port of
the positioner manifold is tubed to the top side of the actuator.
This tubing convention is followed regardless of air action. On
rotary actuators, the transfer case orientation determines the air
action.
Single-acting Actuators
For single-acting actuators, the Output 1 port is always tubed to the
pneumatic side of the actuator regardless of air action. The Output 2
port must be plugged.

WARNING: This product has electrical conduit connections
in either thread sizes 1/2" NPT or M20 which appear identical
but are not interchangeable. Housings with M20 threads are
stamped with the letters M20 above the conduit opening.
Forcing dissimilar threads together will damage equipment,
cause personal injury and void hazardous location certifi-
cations. Conduit fittings must match equipment housing
threads before installation. If threads do not match, obtain
suitable adapters or contact a Flowserve representative.
