R.D02 - Hysteresis (for ON/OFF control)

R.D02 - Hysteresis (for ON/OFF control)
This parameter is available when Pb [r.d01]=0 (On/OFF control
action)
Upper display: Gr.4
Lower display: HYS
Range: from 0.1% to 10.0% of the input span.

R.D03 - Integral time

R.D03 - Integral time
This parameter is available when at least one control output is
configured and Pb [R.D01] is different from 0.
Upper display: Gr.4
Lower display: ti
Range: from 00.01 to 20.00 mm.ss

Above this value the display blanks and the integral
action is excluded

NOTE

NOTE: When the instrument is working with SMART algorithm
the “ti” value will be limited as selected by “ti.Hi” [R.M04] and
“ti.Lo” [R.M03] parameters (if the value is out of limits, the "E.140"
indication will be shown on the middle display, for details see
"Error messages at pag. 83).

Run time group 4 [R.Dxx]

Run time group 4 [R.Dxx]
CONTROL PARAMETERS

NOTE

NOTE: when SMART function is activated, all the parameters
calculated by SMART (Pb, Ti, Td and RCG) cannot be modified.

R.D01 - Proportional band

R.D01 - Proportional band
This parameter is available when at least one control output is
configured.
Upper display: Gr.4
Lower display: Pb
Range: from 0.5% to 999.0% of the input span.

Set 0.0% for On/OFF control action

NOTES

NOTES:
1) The Pb resolution is:

0.1% up to 10.0%;
1% from 10% up to 999.0%.

2) When the instrument is working with SMART algorithm, the

“Pb” value will be limited as selected by “Pb.Hi” [R.M02] and
“Pb.Lo” [R.M01] parameters (if the value is out of limits, the
"E.140" indication will be shown on the middle display, for
details see "Error messages" at page 83)
