Troubleshootings and Abnormalities

Troubleshooting

Messages Information	Possible Causes	Solution
Abnormal communication of ultrasonic components	Too much noise in the power system causes component abnormalities	Replace the power supply. Verify that the power cord is not overwound. Are the wires too close to high-noise electromechanical equipment such as motors and power lines?
	Device exception	Contact the original factory or agent.
Analog current signal unable to output	Abnormal wiring	Please make sure if the cable connection is correct or not.
	The function is not turned on	Please go to parameter E06 to turn on the function.
Abnormal output value of analog current signa	Output value needs to be fine tuned	Please adjust output current value by set-up parameters E11 and E12.
	Excessive Line and measuring resistance	Please confirm if total loop resistance exceeds usage limit, and if it is replaceable. Please increase external supply voltage, proper external supply voltage will increase usage limit of total loop resistance.
	Wrong output parameter set-up	Please confirm the correction of set-up parameter E06 E07 E08 E09 E11 E12 E13.
RS485 Unable to receive response	Communication parameter set-up mismatch	Please confirm the correction of set-up parameter E04 E05.
	Address conflict	Please confirm that there is only one piece of equipment at a specified address.
RS485 signal is unstable	Poor wiring	Please refer to the wiring instructions to confirm if the wiring is correct.
Other abnormalities		Please use parameter H06 to return to the factory parameters.

Abnormality

Issues	Possible Causes	Solutions
Persistent shut-down problems	Unstable power supply	Please confirm if supply voltage and current is within the range.
	Device exception	Contact the original factory or agent.
