1.2 Safety
CAUTION: Before installation, read all safety related
information in section 2 Safety Information.
1.3 Installation - Direct mount
MOUNTING
Securely mount the positioner to the actuator using the bolt
pattern on the back of the positioner. See section 4,
Installation – Mounting, for more detail.
FEEDBACK
Connect feedback linkage. Align the follower arm to move
freely within the expected range of valve travel. Over-rotating
the feedback shaft will not damage the unit.
NATURAL GAS CONNECTIONS
The natural gas connections to the actuator are accomplished
using an approved 4-Way dual solenoid valve (Double acting).
See section 5, Installation - Tubing, for more detail.
CAUTION: Connecting the natural gas supply may cause
the valve to move. Before connecting supply, ensure the valve
is isolated.
Connect the natural gas supply to the input port of the
appropriate 4-Way valve block. See section 15, Positioner
Specifications, for natural gas specifications.
ELECTRICAL CONNECTIONS
CAUTION: Connecting the 4-20 mA signal may cause the
valve to move. Before connecting electrical signal, ensure the
valve is isolated.
Connect a 4-20 mA signal to the terminals labeled “4-20” or
the tabs labeled “HART.” The tabs should only be used for
temporary testing and are not meant as a permanent
connection. A signal above 3.8 mA will activate the positioner.
LEDs on the positioner will light up indicating power is
connected.
The solenoid valve is electrically connected to the positioners
digital outputs using XP approved conduit connections.
1.4 Installation - Remote mount
MOUNTING
The Flowserve Zero Bleed Automation Package provides a
solution for remote mount installations that includes the
positioner and solenoid-controlled valve block as one
panelized package. This package can be mounted to existing
installation panels or can be used stand alone. The positioner
can also be mounted in a customer specific remote mount
application installation. For additional remote mount
installation options and details see section 5 and 6.
