*1 : Confirm the timing for recovery of the origin point of the laser gate from [STAND BY] output. If the origin point recovery
operation is not going to be performed immediately after start up, the connection is not necessary.
*2 : This is the output for confirmation of the laser gate opening/closing timing before test marking, laser check radiation
and laser power measurement. The connection is not necessary if these functions are not going to be used.
This output cannot be used for any operation other than test marking, laser check radiation and laser power
measurement/correction. In normal operations, laser gate opening/closing should be controlled by monitoring the
status of the laser marker and the peripheral equipment with a safety PLC or similar device.
*3 : It is recommended to use the safety devices such as safety PLC for the connection with Laser gate terminal [L-GATE
CL OUT1] and [L-GATE CL OUT2].
