SC Code Descriptions
SM 6-26 D245/D246/D247
SC No. Level Error Name/Error Condition/Major Cause/Solution
547-01 B Zero cross error (relay-contact soldering)
When a zero cross signal is detected consecutively three times
or more, this SC is issued.
When a zero cross signal is detected consecutively less than
three times, the error counter for the zero cross signal
increments, and then the machine retries the checking out the
zero cross signal again.
 Fusing relay defective (contact soldering, contact open)
 Drive circuit of the fusing relay defective
 PSU fuse (24 VS) damaged
 Frequency instability of input power line
 Replace the fusing relay.
 Replace the fuse of the PSU.
SC No. Level Error Name/Error Condition/Major Cause/Solution
547-02 B Zero cross error (relay-contact fault)
When a zero cross signal is detected consecutively three times
or more, this SC is issued.
When a zero cross signal is detected consecutively less than
three times, the machine tries to turn off the relay of the fusing
unit.
 Fusing relay defective (contact soldering, contact open)
 Drive circuit of the fusing relay defective
 PSU fuse (24 VS) damaged
 Frequency instability of input power line
 Replace the fusing relay.
 Replace the fuse of the PSU.
