Real time wind rating calculation:
Wind power rating: 0001 (hexadecimal) = 1 = > wind power rating = 1
COMMON PROBLEMS AND SOLUTIONS
Device cannot be connected to PLC or computer
Possible reasons:
1) The computer has multiple COM ports. The selected port is incorrect.
2) The device address is wrong, or there are devices with duplicate addresses (factory default is all 0x01).
3) Baud rate, check mode, data bit, stop bit error.
4) 485 bus is disconnected, or a and B lines are connected reversely.
5) If the number of equipment is too much or the wiring is too long, it is necessary to supply power nearby, add 485
intensifier, and increase 120
Ω
terminal resistance at the same time.
6) USB to 485 driver is not installed or damaged.
7) The equipment is damaged.
Fault phenomenon: no output or output error
Possible reasons:
(1) The range corresponding error leads to PLC calculation error. Please refer to the technical indicators in the first part
for the range.
(2) Wrong wiring mode or wrong wiring sequence.
(3) The power supply voltage is wrong (for 0-10V type, it is 24 V power supply).
(4) The distance between transmitter and collector is too long, resulting in signal disorder.
(5) PLC acquisition port is damaged.
(6) The equipment is damaged.
