Power Failure
If a power failure occurs, the robot controller automatically removes arm
power.
After a power failure, you must restart the robot controller and manually
turn on arm power. It is recommended that general diagnostics are carried-
out to ensure that the controller and robot are functioning properly.
Electrical Ground
Ensure that the AC power supply is properly grounded. The incoming AC
plug has three wires: live, neutral, and a safety ground. All three wires must
be connected. The safety ground line provides the operator protection
against the exposure to dangerous voltage levels in the case of a fault. In
addition, the safety ground is required to reduce electromagnetic emissions.
The safety ground line of the controller is directly connected to the robot via
the umbilical cable. As a result, it is important that the robot be mounted on
a station that is at the same voltage potential as the ground of the controller.
Ground the station or equipment that the robot arm is mounted onto, to an
industrial grounding rod that is common to the AC ground of the controller,
or to the same utility ground used for the controller. Failure to do so may
result in the risk of fire due to the high currents that may flow in the chassis
ground line of the umbilical cable as a result of the difference in ground
potential.
The C500C controller was designed to be used with a grounded AC system.
Failure to provide a grounded AC input may result in electric shock, and damage to the
controller.
The F3 Robot must be mounted on a station, which is grounded to the same
voltage potential as that of the controller ground. Failure to do so may result in the
risk of fire due to the high currents that may flow in the chassis ground line of the
umbilical cable as a result of the difference in ground potential.
