System Configuration

DIP-Switch Selection Settings—Transmitter

DIP-Switch Selection Settings—Receiver

After mounting, electrically connecting and aligning the
GuardShield PAC safety light curtain, it is now possible to
configure your system.

To begin system configuration, use the security tool provided to
loosen the screw in the configuration door.

Note:

The configuration door screw is a captive screw.

Note:

The transmitter can only be configured for beam
coding and Machine Test Signal. If neither of these
configurations are required, then it is only necessary
to configure the GuardShield PAC receiver.

Identify and set the appropriate dip-switches for the
configuration desired.

Dip-switch identification and function is explained in the tables
below.

Follow the Teach Function Procedure to reconfigure the
GuardShield PAC.

When delivered from the factory, the following settings are
configured.

After each reconfiguration of the GuardShield
PAC, test the system for proper configuration

machine in operation.

ATTENTION

Every modification at the DIP switches must
be stored in the memory of the device
through the Teach function. Simply changing
the position of a dip switch will not change
the GuardShield. It is necessary to first change
the dip switch position and then perform the
teach function. If the changes have been
enabled in the GuardShield, the amber LED
will flash three times as a visual confirmation
that the change has been accepted.

IMPORTANT

GuardShield PAC light curtains with
ArmorBlock Guard I/O connectivity are
configured from the factory as standard
GuardShield PAC light curtains. However, the
only configurable functionality is beam
coding. All other configurable functions have
been disabled.
