Remote High Power On/Off Control
The easiest and most effective way to provide the high power on/off control in a remote loc-
ation is to mount the Front Panel in the desired location with an extension cable.
However, if the user needs to control high power on/off from other control equipment or from
a location other than the Front Panel, then a custom splitter cable will be required. See the
Front Panel schematic (Front Panel Schematic on page 68) for details of the Front Panel's wir-
ing. In this situation, a second momentary contact for high power on/off would be placed in
parallel with the Front Panel push-button contact. This second contact should be suppressed
when in Manual mode (see the note on "Single Point of Control" below).
This method allows relocating the push-button switch to a more convenient location. Imple-
mentation of this method must conform to EN standard recommendations.
NOTE: European standards require that the remote High Power push-button be
located outside of the workspace of the robot.
Pins 6, 14 and 5, 13 of the XFP connector provide this remote capability. Pins 5, 13 provide
power for the lamp, +5 VDC and ground, respectively. Pins 6, 14 are inputs for voltage-free nor-
mally-open contacts from a user-supplied momentary push-button switch.

High Power On/Off Lamp
The Front Panel High Power On/Off Lamp (p/n: 27400-29006) will cause an error, from eV+, if
the lamp burns out. This error prevents High Power from being turned on. This safety feature
prevents a user from not realizing that High Power is enabled because the High Power indic-
ator is burned out. See Changing the Lamp In the Front Panel High-Power Indicator on page
119 for information on changing this lamp.
Remote Front Panel or User-Supplied Control Panel Usage
Users can mount the Front Panel remotely by using an extension cable or by wiring a user-sup-
plied Front Panel (control panel) to the controller using the 15-pin XFP connector. The Front
Panel contains no active components, only switches and lights. Customers should be able to
adapt the Front Panel's functionality into their own Front Panel design. To automatically con-
trol the Front Panel's signals, use relay contacts instead of switches. See the figure Front Panel
Schematic on page 68 for a schematic drawing of the Front Panel, and see the table System
Installation on page 35 for a summary of connections and pin numbers.
NOTE: The system was evaluated by Underwriters Laboratory with our Front
Panel. If you provide a substitute front panel, the system may no longer be UL
compliant.

WARNING: PERSONAL INJURY RISK
To fulfill the "Single Point of Control" requirement, do not place the Manu-
al/Automatic and High Power On controls in multiple locations. After putting
the robot into Manual mode, the operator should remove the key for safety pur-
poses. The system should not be wired so that a PLC or another operator can
put the system back into Automatic mode.
