Fig. N shows the position in which the dip
switches should be set when selecting the light
curtain scanning range for a particular
application.  The dip switches are mounted on
the printed board inside the control module as
shown in Fig. D.  Activate changes by switching
off all power and then on again.

Fig. O shows the position in which the dip switches should be set when
selecting system modes.  The dip switches are mounted on the printed
board inside the control module as shown in Fig. D Activate changes by
switching all power off and then on again.

No interlock: (Mode 1) - 

At power up output switching circuits turn ON

immediately if the light curtain is unobstructed.  Obstruct the light
curtain and the output switching circuits turn OFF.  With removal of the
obstruction the output switching circuits automatically turn ON again
and so on.

Start interlock:

 

(Mode 2) - 

At power up the output switching circuits

remain OFF.  Activation of the start control initiates the output switching
circuits to ON.  Obstruct the light curtain and the output switching
circuits turn OFF.  With removal of the obstruction the output switching
circuits automatically turn ON and so on.

Restart interlock: (Mode 3) - 

At power up the output switching circuits

turn ON immediately if the light curtain is clear.  Obstruct the light
curtain and the output switching circuits turn OFF.  With removal of the
obstruction the output switching circuits remain OFF until the start
control is activated thereby switching the output circuits ON and so on.

Start/Restart interlock:
(Mode 4)- 

At power up the

output switching circuits
remain OFF. Activation of
the start control initiates
the output switching
circuits to ON.  Obstruct
the light curtain and the
output switching circuits

turn OFF.  With removal of the obstruction the output switching circuits
remain OFF until the start control is activated thereby switching the
output circuits ON and so on.  Activate changes by switching all power
off and then on again.
