Re-Transmission Base And Span Scale - FE PXR4 Operation Manual

Re-transmission base scale (Setting range: -100.0 to 100.0%) (Option)
Re-transmission span scale (Setting range: -100.0 to 100.0%) (Option)
[Description]
• The retransmission base scale and span scale can be set
as shown below. Unit for the setting is %.

Note 1: Calculate the set value by using the following for-
mula (refer also to the setting example shown below).
Set value (%) = (A ÷ B) × 100 [%]
A = Temperature to be set – Set value of parameter "P-SL"
B = Set value of parameter "P-SU" – Set value of "P-SL"
[Setting example] At K thermocouple input of 0 to 400˚C, make the setting so that the PV (value of
Since the measurement range is 0 to 400˚C, P – SL = 0 (lower limit value of measurement range), and P – SU = 400 (upper
limit value of measurement range). So, from the formula shown above,
A = (100˚C – 0) or (300˚C – 0), B = 400 – 0 = 400
1) Setting Ao-L : What position is 100˚C in the temperature range from 0 to 400˚C ? = 25% (=(100 – 0) ÷ 400 × 100 [%]) → Ao-L = 25.0 (%)
2) Setting Ao-H : What position is 300˚C in the temperature range from 0 to 400˚C ? = 75% (=(300 – 0) ÷ 400 × 100 [%]) → Ao-H = 75.0 (%)

• When the value of retransmission output (example: SV)
becomes equal to the set value of Ao-L, the retransmis-
sion output becomes 0% (output).
• When the value of retransmission output (example: PV)
becomes equal to the set value of Ao-H, the retransmis-
sion output becomes 100% (output).
