2) Move the optical component to the home position; enable the Weak/Strong
button of the error reporting channel in sequence. If the LED reading of the
error reporting channel is less than 3500 and the optical reading of the
right-side channel is also much lower than the normal value (weak light:
around 1500; strong light: 4095), it will be considered that the LED light of
the error reporting channel malfunctions and the transceiver board E should
be replaced. If the error reporting channel is No. 8 channel and the reading
of No. 8 channel is around 1500 when weak light of No. 7 channel is enabled,
it will also be considered that the LED light of No. 8 channel malfunctions
and the transceiver board E should be replaced.
3) Move the optical component to the home position; enable the Weak/Strong
button of the left-side error reporting channel in sequence. The reading of
the error reporting channel should be around 1500 when weak light is
enabled and be 4095 when strong light is enabled; if the reading is too small,
it will be considered that the receiving chip of the error reporting channel
malfunctions and the transceiver board A should be replaced. If the error
reporting channel is No. 1 channel and the reading of No. 2 channel is
around 1500 when weak light of No. 1 channel is enabled, it will also be
considered that the receiving chip of No. 1 channel malfunctions and the
transceiver board A should be replaced.
4) Check whether the appearance of transceiver wires and the sockets are in
good condition; check whether the wires are properly connected;
5) Check whether the transceiver boards are properly installed;
6) Test whether the 12V supply voltage to the main board is normal; replace
the abnormal power supply.
