*1 SENSOR COMM.ERR.: Communication error between detector substrate and
converter substrate.
*2 PIO COMM.ERR.: Communication error between converter CPU substrate
and input / output substrate.
*3 Alarm release: Forced stop by pressing [DELETE] on the ALARM screen.
: Forced stop is possible.
: Though forced stop is possible, the alarm recurs because
the cause has not been resolved.
