1. Contact your Fisher Controls sales office or sales representative for information for
mounting on actuator types and sizes not listed.
Installation
When Type 304 and 304L switches are ordered with
an actuator, the factory mounts the position switch and
adjusts the cams for the travel specified on the order.
When installation is complete, the cam adjustments
should be checked as described in the adjustment pro-
cedures.
If the position switch has been ordered separately, or
removed for maintenance, refer to the appropriate pro-
cedure for mounting.
Mounting the Position Switch on the
Actuator
To mount a Type 304 or 304L position switch on a
Fisher Controls actuator in the field, see the additional
actuator parts for field mounting section of the parts
list. These additional parts, plus those parts listed in
the position switch mounting parts section, are re-
quired for some actuators.
Refer to the appropriate actuator instruction manual
for procedures to disassemble and assemble actuator-
to-valve connections if required.

WARNING
Avoid personal injury from sudden re-
lease of process pressure. Before disas-
sembly:
D Disconnect any operating lines pro-
viding air pressure, electric power, or a
control signal to the actuator . Be sure the
actuator cannot suddenly open or close
the valve.
D Use bypass valves or completely
shut off the process to isolate the valve
from process pressure. Relieve process
pressure from both sides of the valve.
Drain the process media from both sides
of the valve.
D Use lock-out procedures to be sure
that the above measures stay in effect
while you work on the equipment.
D Vent the power actuator loading
pressure and relieve any actuator spring
precompression.

areas, current monitoring during opera-
