address/polling address has to be within a
range of 1 to 15.
Note:
Communication errors may occur when the
process controller/control station output is
not HART-compatible.
For adaptation, the Z box (order no.
1170-2374) can be installed between out-
put and communication interface.
At the Z box a voltage of 330 mV is relea-
sed (16.5
W
at 20 mA).
Alternatively, a 250-
W
resistor can be con-
nected in series and a 22-
m
F capacitor can
be connected in parallel to the analog out-
put.
Note:
– The load for the controller output will in-
crease as a result.
– The insertion of a capacitor is not per-
missible for intrinsically safe circuits (Ex
ia), energy-limited circuits (Ex nL) and for
the type of protection Ex nA.
