3.2 Wiring precautions
◆
Incorrect connection of the input terminal and output terminal may result in damage to
the product.
◆
Please use the sensor type supported by this product.
◆
Make sure the SSR or load is within the rated range.
◆
Make sure the communication cable is properly connected to the communication
terminals (A, B).
◆
Be sure to connect the polarity (+, -) of the terminal correctly.
3.2.1 Sensor connection
Compensation wire connection
When using a thermocouple sensor, if you extend the wire, use the same size
compensation wire if you use different specifications.
The compensation wire may have a temperature error. Try to choose a
high-performance compensation wire for more accurate temperature measurement.
Measurement error
◆
Do not connect the positive and negative polarity of the sensor.
◆
Please pay attention to maintain the distance between the load and the sensor.
◆
Make sure the sensor is securely connected to the terminal.
AC power wiring
Do not install the sensor near an AC power source.
