NOTE: When P1 has been changed, the P2 and
P10 parametrer will be forced to the minimum
value of the selected range while the P3
parameter will be forced to the maximum value of
the selected range .
P2 = Initial scale value
Initial scale value for input from thermocouple/
Resistance Temperature Detector.
NOTES:
1) When P2 has been modified, the
rLrL
rLrL
rL parameter
will be aligned to it and
rHrH
rHrH
rH parameter will be
forced to P3 value is
rHrH
rHrH
rH <
rLrL
rLrL
rL.
2) When P2 has been modified, if the alarms are
programmed as process alarms (P5=1 and/or
P22=1) and the alarm thresholds are out of
range,
AL.1AL.1
AL.1AL.1
AL.1 and/or
AL. 2AL. 2
AL. 2AL. 2
AL. 2 will be aligned to P2.
P3 = Full scale value
Full scale value for input from thermocouple/
Resistance Temperature Detector.
NOTES:
1) The minimum input span (P3 - P2) is 300°C or
600°F for TC input and 100°C or 200°F for RTD
input.
3) When P3 has been modified, the
rHrH
rHrH
rH parameter
will be aligned to it and
rlrl
rlrl
rl parameter will be
forced to P2 value is
rlrl
rlrl
rl >
rHrH
rHrH
rH.
4) When P3 has been modified, if the alarms are
programmed as process alarms (P5=1 and/or
P22=1) and the alarm thresholds are out of
range,
AL.1AL.1
AL.1AL.1
AL.1 and/or
AL. 2AL. 2
AL. 2AL. 2
AL. 2 will be aligned to P3.
P4 = Out 1 action
This parameter is not modifiable when P5 = 5
rEUrEU
rEUrEU
rEU = reverse action (Heating)
dirdir
dirdir
dir = direct action (Cooling)
P5 = Function of Out 2
0 = Not used or used as event (P22 = 6, 7, 9, 10)
1 = Alarm 1 output - Process alarm
2 = Alarm 1 output - Band alarm
3 = Alarm 1 output - Deviation alarm
4 = Alarm 1 output - Instrument failure alarm
5 = Cooling out
NOTES:
1) Setting P5 = 1, 2, 3:
- if parameter
OLHOLH
OLHOLH
OLH is less than 0, it is set to 100;
- if parameter
IPIP
IPIP
IP is less than 0, it is set to 30;
- if parameters
AL1AL1
AL1AL1
AL1 is out of range, it will be
aligned to the lowest value.
2) Setting P5 = 0 or 4:
- if parameter
OLHOLH
OLHOLH
OLH is less than 0, it is set to 100;
- if parameter
IPIP
IPIP
IP is less than 0, it is set to 30;
3) Setting P5 = 5:
- parameter P4 automatically assumes the
value “
rEUrEU
rEUrEU
rEU”;
- if parameter P16 is out of range, it will be
aligned to the lowest value;
- if parameter Pb is not 0 and is lower than 1.5,
it is set to 1.5.
4) Setting P5 different 0:
- if P22 parameter is equal to 6, 7, 9 or 10 it will
be forced to 0.
