DBL REF MOD (39181)
POINTER KIND (39182) If a laser pointer is installed in the tool head, define whether the active tool or the la
-
ser pointer is to be used as the reference point marker. The offset between the tool
and laser pointer must already have been set while in service mode.
TOGGLE REF PT. (3919) Toggles between ref. point 1 and 2 if 2 reference points have been defined.
VACUUM (392, VAC) This submenu contains commands for the vacuum control system (material hold-
down) and can be called up directly with the VAC key.
PUMP ON/OFF (3921,
VAC+1)
You use this command to switch the vacuum pump/blower on/off.

Procedure
•
Press the VAC key on the operating unit.
• Enter the WIDTH command. The current vacuum width:

me.
During material feed, large size materials can create a relatively large air cushion be

low them while moving forward. This may lead to folds forming in the materials. Swit
-
ching off the vacuum pump/blower during material feeding can prevent this.
If, e.g., a value of 1 second is set, the feeder elements are lowered, the vacuum valve
is toggled, the plotter pulls the material forward. 1 second after the toggle, the pump
is turned off. This causes the air flow to slowly subside, and the air cushion is reduced
slowly during material feed.
TANDEM Tandem mode is activated (=
default).
DBL X DBL X is activated.
DBL Y DBL Y is activated.
