Handling the Teach Pendant
Holding the Teach Pendant and the Deadman Switch
Grasp the teach pendant when operating it, as shown below. The teach pendant has a
deadman switch(es) for ensuring safety.
Deadman switch
Tip
The deadman switch is provided to stop the robot automatically and safely when the
operator can no longer operate the robot correctly due to unforeseen circumstances
such as the operator suffering a blackout or dying while running the robot manually with
the teach pendant. If a situation such as this arises, the strength with which the operator
is pressing the deadman switch will become either decrease or increase markedly. The
deadman switch is a 3-position switch which is able to recognize and react to the
following 3 operating statuses.
1) When the switch is not being pressed or is being pressed lightly
→ Switch: OFF
2) When the switch is being pressed with correct pressure
→ Switch: ON
3) When the switch is being pressed too strongly
→ Switch: OFF
If the switch is OFF or goes OFF, the robot cannot run or the running robot will stop,
respectively.
In order to ensure safety, the robot is so designed that in manual mode the deadman
switch should be held down for example when the operator presses any of the arm
traverse keys.
Note: The deadman switch is also called "Enable switch."
