Precautions for Safe Use
If the supplied Front Panel is not used, a High Power indicator light must be present in the sys-
tem. This indicator light must be amber in color. It must be either mounted to the robot or inte-
grated into the work cell where it is visible from all approaches or entry points.
Precautions for Correct Use
• Either a Front Panel or equivalent circuits are required to enable High Power to the robot. Re-
fer to XFP Wiring Diagram on page 3-38 for more information.
• If the Front Panel High Power ON / OFF indicator fails, you might incorrectly assume that
High Power is OFF, and the robot is safe. To prevent this, a failed indicator causes an error
(-924) *Front panel HIGH POWER lamp failure* and locks out the High Power enabling until
you replace the indicator. Refer to the V+ User's Manual (Cat. No. I671) for more information
about error handling. Refer to High Power Indicator Check Procedure on page 3-48 for infor-
mation about High Power indicator operation verification.
Additional Information
• The Front Panel is supplied with an extension cable that must be used to connect it to the
XFP connector on the XSYSTEM cable. Refer to 3-8-1 Installing the Front Panel on page
3-34 for more information.
• Design of the factory-supplied Front Panel E-Stop is in accordance with the requirements of
IEC 60204-1 and ISO 13849.
• If you supply your own Front Panel, its design must comply with the requirements of
IEC 60204-1 and ISO 13849. The E-Stop's push button must comply with ISO
13850 (Clause 5.5.2).
• If an operator is going to be in the work cell with the switch in Manual mode, the
operator must carry an enabling device such as the T20 pendant.
• Whenever possible, perform Manual mode operations with all personnel outside the
workspace.
• Disabling the High Power button violates IEC 60204-1. Do not alter its functionality.
• In Automatic mode, the robot can move unexpectedly. Ensure all personnel remain
clear of the cell when Automatic mode is enabled.
