Hitachi LM-C300 Series User Manual page 83

CODE FAULT
0x48 XY out of range
0x54 RTC battery failure
0x63 FPGA failure
0x65 Shutter not open
The user is not always informed of all alarms when there is a failure. The user needs to decide whether
or not to have the system report the following alarms:
 Belt Stop
 Over Speed
 Trigger signal
 Laser Interlock
 Shutter closed
 Empty message
 OEM Shutter
 Maximum distance alarm
 Minimum distance alarm
The alarms other than the above always report failures to the user.
CAUSE
1. There is a message outside the print
area.
2. The encoder signal may contain
noise.
1. The voltage of the coin battery is low. 1. Replace the coin battery.
1. It may have been affected by external
noise during use.
1. The shutter is closed.
1. Move messages so that all messages
are placed in the print area.
2. Check if there is a noise source
arround. If there is a noise source,
remove the noise. Please read
"Chapter 0. WARNING" to improve
noise resistance.
1. Please restart the Laser Marker.
2. In this environment, the same error
may occur again. Read "Chapter 0.
WARNING" to improve noise
resistance and do not touch the
connector on the back of the LM during
operation. (The human body is also a
source of electrostatic noise.)
1. Check if the sensor lamp of the optical
box is switched by opening and closing
the shutter. If not, the board may be
damaged. Please contact your
HITACHI distributor.
