The model number of the transducer or transmitter will designate the full-scale pressure capability.
For example, model number TPT432A-5M-6/18 indicates that the full-scale pressure is 5,000 (5M),
while the PT150-5C indicates that the full-scale pressure is 500 (5C). Since the default value in the
instrument is 10,000 full scale, the input full-scale value must be changed to 5,000 (or 500). Note
that there are no units here, it can be psi, bar, mPa, kg/cm2 or any engineering unit; the magnitude
is all that is important. To set the full-scale value, press the
FUNC
key until
nonE
and
GROUP
show
on the display. Press the
▲
key until
3
shows in the upper display. Press the
FUNC
key and the
upper display will show
10000
while the lower display shows
PI.FSV
. Hold the
▼
or
▲
key until the
upper display changes to
5000
(or whatever the full-scale value of the primary input may be). Press
the
FUNC
key to set the value. Check that the next display reads
0
in the upper display and
PI.LSV
in the lower display; if not, set to zero with the arrow keys and press
FUNC
to lock in the value.
Finally, press the
RESET
key to go back to the active display. Similarly, if the full-scale pressure is
350 Bar (3.5CB), set
PI.FSV
to 350.

For applications where a low scale value is non-zero, the Instrument can provide a low scale value
of
±
25% of the full scale value.
To set the low-scale value, press the
FUNC
key until
nonE
and
GROUP
show on the display. Press
the
▲
key until
3
shows in the upper display. Press the
FUNC
key and the upper display will show a
value while the lower display shows
PI.SFV
. Press the
FUNC
key and the upper display will show
0
while the lower display shows
PI.LFV
. Hold the
▼
or
▲
key until the upper display changes to
whatever the low-scale value of the primary input may be. Press the
FUNC
key to set the value.
Finally, press the
RESET
key to go back to the active display.

The Primary Input Failsafe Mode is nothing more than a safety mechanism that tells the instrument
what to do in the event of a loss of the primary signal. If the system is set up to shut down the
process in a high alarm condition, the Primary Input Failsafe parameter sets the value of the primary
input to full scale if it looses the primary signal. If the system is set up to shut down the process in a
low alarm condition, the Primary Input Failsafe parameter sets the value of the primary input to low
scale if it looses the primary signal. The default Primary Input Failsafe Mode is to set the value to full
scale high.
