OPEN INPUT CIRCUIT
This instrument is able to identify the open circuit for TC
and RTD inputs.
The open input circuit condition for RTD input is shown by
an "overrange" indication.
For TC input, it is possible to select overrange indication
(standard) or underrange indication setting the CH102 and
SH102 according to the following table:
Overrange (STD)
CH2 = close
SH2 = open
Underrange
CH2 = open
SH2 = close
Both pads are located on the soldering side of the CPU
card

SELECTION OF THE OUTPUT 2 TYPE
For the output 2 it is possible, by J303, to select the
contact used (N.O. = 1-2 (STD) or N.C = 2-3) as shown
below:
