These sensors are divided into three zones that represent the front, middle and rear of the 
laser  plane  (the

  signals).  If  an  obstruction  blocks  the  laser  light  to  any  of  the 

sensors,  the  receiver  will  turn  off  the  appropriate  signal,  and  the  PGS-2  controller  will 
immediately disable downward movement of the press beam.

Laser Classification and Warnings 

 

Warning: CLASS 1 LASER DEVICE

 

The LZS-1 laser transmitter emits CLASS 1 planar laser light approximately 
50mm in width. Do not stare directly into the laser or the transmitter window. 

 

 

Warning: CLASS 3R LASER RADIATION: DO NOT OPEN OR TAMPER WITH 
THE LASER TRANSMITTER 

The  LZS-1  laser  transmitter  contains  no  user  serviceable  components.  Do  not 
attempt  to  tamper  with,  or  dismantle  the  laser  transmitter  as  this  will  void  the 
product  warranty  and  may  expose you  to the  internal  laser  emitter  CLASS  3R 
LASER RADIATION that has the potential to cause eye damage.  

 

3.3.3

 

Setup 

Prior to operating the machine, and after a tool change, it is necessary to check that the laser 
is set to the correct distance below the punch tip. The laser to punch distance is configured 
during installation of the system, according to the maximum stopping distance of the machine, 
so  that  when  an  obstruction  occurs  the  machine  can  stop  before  the  tool  tip  reaches  the 
obstruction, see 

Figure 3-3

. 

Stopping 

Distance

 

Figure 3-3: Stopping Distance 

The stopping performance of the machine is measured by an overrun test at start-up, and is 
automatically monitored relative to the laser to punch setting on every machine stop. If the 
machine is operated continuously, the overrun test is repeated every 24 hours. 

The laser to punch distance setting for your machine can be viewed in the Operator Panel by 
navigating to the System Information screen (see 

Section 5.7.1

).
