3610J and 3620J Positioners
Installation
Normally, a positioner is shipped with the actuator. If
so, the factory mounts and calibrates the positioner
and connects the positioner to actuator tubing. If the
positioner is ordered separately from the actuator,
perform the appropriate mounting procedure, and
follow the Calibration procedures in this instruction
manual. Refer to the appropriate instruction manuals
for actuator and valve mounting procedures.
WARNING
Avoid personal injury from sudden
release of process pressure. Before
mounting the positioner:
D Always wear protective clothing
gloves, and eyewear when performing
any installation operations to avoid
personal injury.
D When installing 3620J Series
positioners in a hazardous area, turn
off control signals until installation is
complete. Be sure all safety barriers,
connections, and the converter
housing cap and O-ring are properly
installed before applying a control
signal to the unit.
D If installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section.
D Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
WARNING
Personal injury or property damage
may result from fire or explosion if
natural gas is used as the supply
medium and preventive measures are
not taken. Preventive measures may
include: Remote venting of the unit,
re-evaluating the hazardous area
classification, ensuring adequate
ventilation, and the removal of any
ignition sources.
