Notes
Verify the power supply specification before wiring to avoid device burnout.
Distinguish power terminal, channel 1 and channel 2 input/output terminals strictly during wiring.
Keep the controller away from high-power electromagnetic equipment to avoid signal crosstalk.
Install in dry, ventilated environment without corrosive gas, dust and condensed water.
Two channels shall not access conflicting high-frequency signals to ensure independent operation.
Cut off power supply before maintenance, wiring modification and parameter resetting.
Equip reliable grounding to enhance anti-interference performance of dual channels.
Do not operate beyond rated temperature, humidity and load range.
Unauthorized disassembly will invalidate the after-sales warranty service.
Set independent alarm parameters for two channels according to on-site working conditions.
