NOTE: selecting P1 = 0, 2, 4, 6, 10 or 28, the
instrument set automatically P43 =
filt
. For all
the remaining ranges it will set P43 =
nOfl
.
P2 = Decimal point position
This parameter is available only when a linear
input is selected (P1 = 13 to 20).
----.
= No decimal figure.
---.-
= One decimal figure.
--.--
= Two decimal figures.
-.---
= Three decimal figures.
P3 = Initial scale value
For linear inputs, it is programmable from -1999 to
4000 and P3 value may be greater than P4
value in order to obtain a reverse read-out.
For TC inputs, it is programmable within the input
range.
When this parameter is modified, rL parameter will
be re-alligned to it.
P4 = Full scale value
For linear inputs, it is programmable from -1999 to
4000.
For TC inputs, it is programmable within the input
range.
When this parameter is modified, rH parameter will
be re-alligned to it.
The initial and full scale values determine the input
span which is used by the PID algorithm, the
SMART and the alarm functions.
NOTE: the minimum input span (S = P4 - P3), in
absolute value, should be set as follows:
- For linear inputs, S > 100 units.
- For TC input with °C readout, S > 300 °C.
- For TC input with °F readout, S > 550 °F.
P5 = Output 1 type
sm.Ol
= servomotor open loop.
sm.Cl
= servomotor close loop.
rEU
= time proportional control output with reverse
action
dir
= time proportional control output with direct
action.
NOTES:
1) If P5 is changed to "
sm.Ol
" or it is changed from
"
sm.Ol
" to another selection, the parameter P41
will be forced to 0.
2) If P5 is changed to "
rEU
" the cycle time (
Cy1
) will
be forced to 15 s
3) If P5 is changed to "
dir
" the cycle time (
Cy1
)
will be forced to:
10 s when P25 =

4 s when P25 =

2 s when P25 =
