Location of Matrix
Description of Function
Current
V4 H0
Displays the temperature measured. The
bar graph shows the output value for the
programmed output range as a
percentage.
Selection of unit
V4 H1
Unit of measure to be used to display the
temperature in matrix field V4 H0. Options
available for selection:
0 =
o
C
1 =
o
F
Adjustment of temperature range of 4 to 20
mA output (circuit 2)
V4 H5
V4 H6
Unit value of measure to be used for the 4
to 20 mA temperature output. The value
range for both positions lies between 0 and
150. The output range is always specified in
o
C independent of the display unit
selected.
Default: 0 (V5 H5) …. 150 (V4 H6)
Loop 2 at fault
V4 H7
Status of current output 2 when an error
has occurred in the temperature
measuring circuit.
Options available for selection:
0 = 110% (22 mA)
1 = - 10% (3.6 mA)
2 = hold at previous level Default: on
instruments equipped with display: 0 on
instruments not equipped with display:
selected by order code.
Adjustments of current output 2
V7 H8
V7 H9
Adjustment of 4 to 20 mA hardware
settings for the temperature output. This
output is pre adjusted by the factory and
normally does not need readjustment. To
check the setting, connect a current
measuring instrument in series with circuit
2. The output signal in position V7 H8 is
automatically switched to the 4 mA setting,
and V7 H9 is automatically switched to the
20 mA setting. The + and - keys can be
used for fine adjustment. Move on to any
other matrix field to return the output signal
to reflect current measured values.
Default: On instruments not equipped with
display: based on order code
