Base Function Override Switch

Isolating a Malfunction

In the event that the Base Overtravel limit switch is malfunctioning, the Base functions
can be operated by pressing the Override Switch on the Power Supply PC Board.

WARNING

The overriding of the Overtravel limit switch should only be
done after an inspection of the equipment determines the
product is acceptable to be moved. Failure to do so may result
in personal injury or damage to the table.

Equipment Alert

Operating any function beyond the factory
pre set limits may cause damage to table.

TP210 Rev. A To override...
A) Unplug table power cord.
B) When the digital display on the Machine Control Board darkens,
press and hold the Override switch (S3) on the Power Supply PC Board.
C) While holding the Override switch, plug in table power cord.
D) Continue to hold the Override switch while pressing the Base UP / DOWN
button on the Hand Control and motion will be allowed.
E) When testing is complete, unplug table power cord.
F) When the digital display darkens, plug in table power cord.
