• This command is available only when the shutter control method is set to "communication commands" by Laser Marker
NAVI smart.
• When you transmit the shutter open request command with the shutter already open, the laser marker returns the
negative response.
• If the shutter close command is transmitted during marking, the internal shutter is closed after the marking is completed.
• There is a delay time of around 200ms to max. 1 second from sending shutter open/close command for the actual
shutter open/close operation time.
• With LP-RC series for the first operation of opening shutter after the laser pumping on, it takes around 300ms to max. 4
seconds.
• For LP-RC series, the shutter can be opened after turning on the laser pumping. When the laser pumping is turned to
off, the shutter is closed automatically.
• With LP-RC series for the first operation of opening shutter after the laser pumping on, warning E641 may occur in case
the laser pumping has been off for more than several days. In this case, send the shutter close request or input alarm
reset to recover from the warning status, and then retry opening the shutter.
• SHT command is not acceptable during the guide laser emission or laser radiation for measurement.
• It is possible to recover from the warning status by closing the shutter.
