match the remote device analog input type used to remotely display the Delta
Pressure.
9. Press the FUNC button to save and move to the next parameter.
10. DEFLT will be displayed. This is only used to default the Group 5 parameters back
to Factory Defaults. This is performed by pressing the
t
arrow until ON 5 is
displayed and then press the FUNC button to default otherwise press FUNC again
to return to the GROUP display.
Group 4 – Shunt and Failsafe Settings
1. Pressure FUNC until Group is shown on lower display. Press the t arrow to select
Group 4.
2. Press FUNC again to move to SHUNT parameter. Depending on type of sensor
connected to the primary and secondary inputs Shunt Calibration may or may not
be used. Generally Shunt Cal is used on Strain gage transducers with millivolt
output because calibration is performed at the Process indicator. Shunt should be
set to OFF when using Transmitters with milliamp or volt outputs because the
calibration is generally performed on the transmitter itself using zero and Span
adjustments.
Note: Setting the SHUNT to off, the indicator will assume the span calibration will
be the full scale of the sensor connected to the input.
3. Press FUNC to save and move to the next parameter. SHNT.% will be displayed
on the lower display (If previous operation set SHUNT to ON). Using the t or u
arrows, the % can be adjusted from 40.0 to 100.0 % of full scale. Dynisco Melt
Pressure Transducers utilize 80% Shunt Cal output. Consult the manufacturer’s
documentation for recommended Shunt Calibration setting if using the controller
with other sensors.
4. Press FUNC to save and move to the next parameter. PI.IFS will be displayed.
Primary Input Failsafe can be set to HI or LO depending on the desired action if
there is a sensor break. If set to HI, the process input will go high and cause any
actions to react as if the process variable has increased to maximum. This includes
any alarms and control output. Setting PI.IFS to LO will cause the process input to
go to minimum if there is a sensor break.
5. Press FUNC to save and move to the next parameter. SI.IFS will be displayed.
This setting is for the Secondary Input Failsafe and reacts the same as the Primary
Input if there is a sensor break on the secondary input. Press
FUNC to save the
SI.IFS setting.
6. The remaining parameters in Group 4 relating to Alarm action, Logic Input function
are outlined in section 8.
Group 3 – Display scaling and indication
1. Proceed to Group 3 parameters by pressing the FUNC button until Group is shown
on lower display and None is shown on upper display. Press the
t
arrow until
Group 3 is displayed.
2. Press the FUNC button until PI.FSV is displayed. Using the
t
and
u
arrows, set
the Primary Input full scale value to match the full range of the sensor connect to
the Main input.
