Terminal No. Name / Description
X10 SHUTTER A: Shutter control input A
The shutter inside head is opened while the terminal remains in ON position. (The terminal control is
available during shutter control Input B ON).
There is a delay time of around 200ms to max. 1 second from turning ON/OFF of SHUTTER A/B IN for
the actual shutter open / close operation time.
This terminal is available when the DIP switch No. 2 is turned OFF.
X11 SHUTTER B: Shutter control input B
Control by the shutter control input (A) is available during shutter control input (B) ON. The input
becomes ON by short-circuiting between X11: shutter control input (B) and X12: OUT COM. Normally,
use these terminals in input ON.
WARNING
• Do not use Shutter Control Input as the interlock. If Shutter Control input
becomes ON during laser emission, the shutter is closed after the marking
operation has been finished.
X12 OUT COM.: Output common
The common terminal for each output of the I/O terminal and I/O connector. Y2, X12, X15, X18 and
No. 37 of I/O connector are the common terminal connected internally. In case of NPN connection,
this terminal is connected to the “- (minus)” side of power which is used for control. In case of PNP
connection, this terminal is connected to the “+ (plus)” side of power which is used for control.
X13 ALARM RES.: Alarm reset input
The reset input for restoring the system from the alarm status.
Make sure to verify the safety by eliminating the alarm causes before turning this input ON.
The alarms caused by hardware or system error cannot be recovered by this input. In this case, restart
the laser marker.

LASER STOP 1: Laser stop 1 input (LASER STOP 1A: Laser stop 1 input A at LP-Mxxx-LS1)
LASER STOP 1B: Laser stop 1 input B (Equipped only in LP-Mxxx-LS1) *1
LASER STOP 2A: Laser stop 2 input A
LASER STOP 2B: Laser stop 2 input B
Use these terminals to stop the laser radiation or disable the laser radiation temporarily.
When between either of LASER STOP terminals and OUT COM. are disconnected, the laser radiation
will be disabled.
The laser marker operates as shown below according to the terminal and its open status. For details,
refer to “Laser marker operation at inputting the safety functions” (P.25).

The function relating to safety must be shut off mechanically. Therefore, it is recommended to wire these
terminal at no-voltage contact (dry contact). If you need to shut off the laser pumping physically, user the
interlock connector instead of these terminals.
