Use a suitable supply pressure regulator to reduce the supply pressure to the normal operating supply pressure shown
in table 3. As shown in figure 9, a 67CFR filter/regulator mounts on the back of the controller/transmitter case and
mates with the supply pressure connection on the controller/transmitter case. Pipe the supply pressure to the IN
connection of the regulator. Typically, the 67CFR filter/regulator accepts supply pressures between 2.5 and 17 bar
(35 and 250 psig). For specific regulator limits, refer to the appropriate regulator instruction manual.
If operating the controller or transmitter from a high pressure source [up to 138 bar (2000 psig)], use a high pressure
regulator system, such as the 1367 High Pressure Instrument Supply System. For 1367 system installation,
adjustment, and maintenance information, see the separate instruction manual.
Controller/Transmitter Output Connection
As shown in figure 9, the output pressure connection is on the back of the controller/transmitter case. After
connecting the output pressure line, turn on the supply pressure, adjust the filter/regulator to the appropriate supply
pressure required for the controller/transmitter and check all connections for leaks.

WARNING
Personal injury or property damage could result from fire or explosion of accumulated gas, or from contact with hazardous
gas, if a flammable or hazardous gas is used as the supply pressure medium. Because the instrument case and cover
