Field Muted Mode
WARNING: NO PROTECTION IN FIELD MUTED MODE
In Field Muted mode, the optical sensing is deactivated. Although the LZS-003-HS
ensures that the machine does not exceed crawl speed in this mode, particular
caution must still be exercised.
The LZS-003-HS Operator Panel requires a password to enable the Field Muted
mode button. The password should only be available to suitably trained personnel.
Field Muted mode should only be used by suitably trained personnel and only
in exceptional circumstances (changing tools, maintenance, etc.)
In this mode, protection from the laser is muted for the entire stroke of the beam and therefore
does not provide protection. The LZS-003-HS however maintains all its other safety functions.
For example, it continues to monitor that the closing of the tools occurs at crawl speed and
stops the machine if that speed is exceeded.
The Field Muted Mode should only be used in cases where no alternative mode with activated
protection exists. It is recommended that the Field Muted Mode only be activated by
supervisory personnel. Field Muted Mode can be locked and password protected.
3.2.7
Stop at Mute Point
The auxiliary
Mute Stop
mode may be engaged to cause the beam to always stop at the mute
point. It is particularly useful when the back gauge is set close to the die causing the rear
section of the laser to be interrupted. The rear section of the laser is muted within the area
10.0mm above the material to clear back gauge obstructions.

When changing the tools the transmitter and receiver can be easily moved clear so that the
punch can be removed from either end of the machine. To realign the transmitter and receiver
each is moved quickly back into position. The laser is adjusted to the correct distance from the
punch tip with the aid of an alignment tool. The receiver is simply positioned so that the laser
strikes any where in the 40mm window reception area. In most tool changes the receiver does
not require any adjustment if the punch depth changes by less than 20mm. After the tool
change is complete the mute point is then quickly and easily reset during the first stroke.
