Input sensor
◆
If it is unavoidable to avoid the temperature detected by the sensor due to
environmental factors, please use the deviation correction to minimize the error.
◆
When using a thermocouple sensor, please use the compensation wire of the rated
range when extending the wire. Otherwise, the joint between the thermocouple and the
extension wire will be thermally deformed, resulting in inaccurate measurement
temperature.
◆
If using a RTD sensor, connect three terminals and use three cables with the same
material, thickness and length. Otherwise, thermal deformation may occur, resulting in
inaccurate measurement temperature.
。
◆
When changing the input sensor, please disconnect the power supply, connect the
new sensor, and then power on the PC to modify the relevant parameters.
◆
Install the filter on the controller. In addition, install the shield wire near the power
supply.
Noise impact
◆
Product power line and high-voltage line are separately routed to prevent impulse
noise interference.
◆
Please try to avoid high frequency noise interference in the environment, such as
welding machine, sewing machine, high-capacity SCR controller and high-capacity motor.
◆
Do not use this product in accessories of high frequency broadcast, TV and wireless
equipment.
Communication
◆
Use twisted pair cable for communication cable and ferrule on both sides of the
cable to reduce external noise interference.
◆
Do not arrange communication cables on the AC power accessories.
◆
Pleease use independent power supply voltage (24VDC) for communication
converter.
