Special features when using Cu10 sensors
● Choose "Thermal resistor (3-wire connection)" and "Cu10" in the parameter assignment.
● Wire the Cu10 sensor into the 3-wire connection technology.
● During operation, automatic, internal compensation of the line resistance of the missing
measuring line takes place.
Note
To ensure optimum line compensation with Cu10, please observe the following:
• An accurate measured value is only attained if the cable resistance of the positive
const
ant current line to the Cu10 sensor and the cable resistance of the negative
measuring line are identical in value.
• Recommendation: Keep the measuring line as short as possible.
• Different resistance values may also occur due to the connection method used.
