21 = TC type L range 0 / +1650 °F
22 = TC type J range -150 / +1830 °F
23 = TC type K range -150 / +2500 °F
24 = TC type T range -330 / +750 °F
25 = TC type N range -150 / +2550 °F
26 = TC type R range 0 / +3200 °F
27 = TC type S range 0 / +3200 °F
28 = TC type B range 0 / + 3310 °F
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 = Air
4 s when P25 = OIL
2 s when P25 = H2O
