Precautions Before Use

Precautions Before Use
Accuracy
When extremely sensitive temperature data is required, use the temperature data obtained 15
minutes after turning ON the FP0 RTD unit. (The temperature data obtained in the first 15
minutes is, however, within the total accuracy range.)
A rapid temperature change in the FP0 RTD unit might change the temperature data
temporarily.
A draft (air) created e.g. by a cooling fan built into the control panel and blowing on the FP0
RTD unit will lower accuracy. Avoid any kind of draft.
Programming
Between power ON and the first valid conversion data, the digital value will be 8191 or 16383.
When programming, be sure not to use the data obtained during this period.
When the RTD is broken, the digital value will change to 8191 or 16383. When programming
avoid any risks resulting from a broken RTD. A broken RTD needs to be replaced.

1.1 Functions
RTD input unit for the FP0/FP0R and FPΣ/FP0H CPU.
The temperature data obtained using the RTD (Resistance Temperature Detector) is
converted to the digital value to be read into the CPU.
Available RTD types
Pt100 (to IEC751), Pt1000 (to IEC751), Ni1000 (to DIN43760), and Resistor.
