Risk Assessment and System Design Chapter 1
The application follows this sequence of operation.
1. The Panel Assembly Feed Conveyor (B) indexes the panel into Panel Position Station #2.
2. The operator loads the part at Station #1 (A).
3. The operator initiates a part ready sequence to activate the robot.
4. Robot (C) picks part from Station #1 (A).
5. The robot inserts the part from Station #1 into a panel on the Panel Assembly Feed Conveyor.
6. The robot picks the assembly from Panel Assembly Feed Conveyor (B) and places it into the Inspection Station
(D).
7. The Overhead Transfer Gantry (E) transfers the assembly to the Transfer Elevator (F).
8. The Transfer Elevator (F) indexes one position to complete the cycle.
The machine operating modes, as defined by the operators, are Automatic, Manual, and Jog with gates open. The Jog
mode operation is required for the movement of the following equipment.
Equipment Movement
Robot (C) 5 axis
End of Arm (EOA) tooling
Overhead Transfer Gantry (E) X-axis
Y-axis
End of Arm (EOA) tooling
Parts Transfer Elevator (F) Index

S = Severity of injury S1 Slight (normally reversible)
S2 Serious (normally irreversible including death)
F = Frequency or exposure to hazard F1 Seldom to less often and/or the exposure time is short
F2 Frequent to continuous and/or the exposure time is long
P = Possibility of avoiding the hazard or limiting the harm P1 Possible under specific conditions
P2 Scarcely possible
