3-4-2 How to Display and Set Parameter Data
PV and SV (Display Level 0)
PV
SV
Process value (monitored every 500 ms)
Currently set set value. Units:
°
C or
°
F. The SV can be
changed from this display.
Valid SV Range
Set the SV in the range between the SV lower limit and the SV upper limit.
Error Display
When a sensor error occurs, one of the codes below and the detected tempera-
ture blink alternately in the PV display.
ser1
Temperature is out of the range: (sensor measurement range
±
10%FS). That is, 10%FS below the lower limit or 10%FS above
ser2
10%FS). That is, 10%FS below the lower limit or 10%FS above
the upper limit. Includes broken or incorrect sensor wiring.
ser1
: Loop 1;
ser2
: Loop 2
serr
Abnormality in the cold junction compensating circuit. Applies to
thermocouple type only.
SP Lower Limit (Display Level 1)
PV
SV
SP lower limit parameter symbol
Currently set SV lower limit. Units:
°
C or
°
F.
The SV lower limit can be changed from this display.
When the sensor type is set with SW202 on the rear of the Unit, the SV lower limit
is automatically set to the measuring range lower limit of the selected sensor, as
shown below. However, the SP lower limit cannot be changed if the current SV
lies inside the sensor measuring range.
Default values TC: –200
°
C
Pt: –99.9
°
C
Change the set limit, if required. Set the lower limit in the following range:
Sensor measuring range lower limit to (SP upper limit – 1 digit)
The SV and “----” blink alternately on the display if the SP lower limit is set outside
the limit defined above to indicate that the value is out-of-range. Reset the SP
lower limit inside the permitted range.
SP Upper Limit (Display Level 1)
PV
SV
SP upper limit parameter symbol
Currently set SV upper limit. Units:
°
C or
°
F.
The SV upper limit can be changed from this display.
When the sensor type is set with SW202 on the rear of the Unit, the SV upper
limit is automatically set to the measuring range upper limit of the selected sen-
sor, as shown below. However, the SP upper limit cannot be changed if the cur-
rent SV lies inside the sensor measuring range.
Default values TC: 1300
°
C
Pt: 450.0
°
C
Change the set limit, if required. Set the upper limit in the following range:
(Sensor measuring range lower limit + 1 digit) to SP upper limit
The SV and “----” blink alternately on the display if the SP upper limit is set out-
side the limit defined above to indicate that the value is out-of-range. Reset the
SP upper limit inside the permitted range.
