Hazardous Area Installations
The positioner is available in versions suitable for use in
hazardous areas. The labeling on the positioner indicates
correct areas of use.
WARNING: Installation of any hazardous area
equipment must be made in accordance with the
appropriate hazardous area installation codes
and the manufacturer’s installation and operat-
ing instructions. The user must make no changes
or attempt any repairs of a certified instrument
since this will invalidate the certified design. If a
certified instrument should fail it must be re-
turned to the manufacturer for repair.

Split Range Operation
Split ranging permits operation of two valves in sequence
from one 4-20 mA control signal. To accomplish this with
the 4700E, the two positioners are connected in series as
shown in Figure 13, with the actual split ranging done by
proper cam segment selection per tables on pages 27 - 29.
Note: With this configuration, the voltage burden of the
4-20 mA controller is 10 V instead of 5 V.
