GuardShield Remote Teach
Introduction
The GuardShield Remote Teach system provides a remote means of
changing a fixed blanking configuration within the GuardShield safety
light curtain. This keyswitch box eliminates the need to open the
GuardShield receiver door and perform the Teach function.
When a machine setup has been changed, which requires a new fixed
blanking field to be configured, the GuardShield Remote Teach box is
the ideal solution.
An IP65 metal keyswitch box is designed to be located in the vicinity
of the GuardShield light curtain receiver. The Remote Teach box
should be mounted in such a way as to allow the operator performing
the Teach function a clear view of the area being blanked out
The GuardShield receiver requires a modified right angle mounting
bracket to fit around the cable gland hardware on the receiver endcap.
This bracket is supplied with each GuardShield remote teach receiver.
The GuardShield Remote Teach Box system consists of the following;
• Remote teach keyswitch box with mounting plate and two keys
• GuardShield transmitter
• Two meter patchcord for connection between the 4 pin pigtail
connector and the remote teach box.
• GuardShield receiver with a ten-inch dual connector pigtail. The
dual connector contains a four-pin micro quick disconnect as
well as a standard eight-pin quick-disconnect GuardShield
Receiver.
• Modified mounting bracket for receiver bottom endcap
Figure 6: GuardShield Remote Teach Components
Note: The GuardShield remote teach box can not be retrofitted.
It is possible to purchase the components separately. If a
GuardShield system has already been purchased, the
transmitter is a standard transmitter. The receiver part
numbers vary by protective height. Refer to the Remote
Teach System table for a list of component parts of a
remote teach system.
System Delivery
The GuardShield Remote Teach system is delivered with the
GuardShield transmitter and receiver configured in the standard
GuardShield operating mode of “Guard Only,” which is Automatic
reset, and all features not activated.
The two meter patchcord (889D-F4ACDM-2), Remote Teach
(440L-M8600) keyswitch box and mounting hardware are packaged
with each GuardShield Remote Teach system along with a standard
GuardShield transmitter and remote teach receiver.
Remote Teach Box — Key Switch Positions
The GuardShield remote teach box utilizes a Rockwell Automation
800FM series, three-position IP66 rated keyswitch. There are three
keyswitch positions on the GuardShield Remote Teach box as shown
below.
RUN: This keyswitch position is required for the GuardShield light
curtain to operate in its normal operating mode.
CONFIGURE: This keyswitch position simulates the opening of the
GuardShield DIP switch door. This position sends a signal to the
GuardShield firmware to change from the RUN mode of operation to
a configuration mode of operation in this mode, all outputs are in the
OFF state.
TEACH: This keyswitch position performs the function of changing
the operating mode configuration of the GuardShield light curtain.

System Installation
The GuardShield light curtain transmitter and receiver should be
properly mounted to the machinery to be guarded per the GuardShield
Installation Instructions.
After aligning the GuardShield safety light curtains and attaining a
“Green” state, the GuardShield safety light curtain is transmitting
infrared light and the GuardShield receiver OSSDs are high, it is
possible to reconfigure the GuardShield.
Using the T8 Torx bit supplied with each GuardShield bracket kit,
open the GuardShield Receiver door and set DIP switch four to the
ON position. This DIP switch allows the activation and configuration
of a monitored fixed blanked area within the GuardShield protective
height.
Make any additional DIP switch settings at this time.
NOTE: If EDM or Reset functions are to be configured through DIP
switch settings, assure that the proper receiver wire connections are
made.
It is not possible to blank out the synch beam,
which is the first beam adjacent to the
GuardShield diagnostic LEDs.
