errors
Sensor1 (Fld dev
stat0-1)
Sensor1 error is
detected.
1. Check Sensor1 for
damage.
2. Check terminal connection.
3. Check cable resistance
value setting. Set double
of the cable resistance
between the sensor and the
device. It is necessary for
2-wire, 3-wire and 4-wire
RTDs/ohms to compensate
cable resistance.
Sensor2 (Fld dev
stat0-2)
Future use
N/A
CJC/electronics
sensor (Fld dev
stat0-3)
CJC failure is
detected.
Use CJC connector for
thermocouple measurement.
