emergency stop button a red push button on a yellow field that locks when a person pushes it
(the electrical contacts stay open). It is necessary to turn the button clockwise to unlock it. A
machine can have zero or more emergency stop buttons.
kick plate a metal plate on a shuttle conveyor that operates a switch when an object applies suf-
ficient force to the plate. The kick plate is usually the first component of the shuttle to hit an
object in the shuttle path. All Milnor
®
shuttles that go left/right on a path have kick plates on
the two sides of the machine.
WARNING: — You can be killed or severely injured if a shuttle strikes you even if you
come in contact with the kick plate first.
� Never do a test of the kick plate when the shuttle operates.
pull cord a wire on a conveyor that operates a switch when a person pulls the wire. All Milnor
®
free-stand conveyors (a conveyor that is not a component of a larger machine) have pull cords
on the two sides of the conveyor.
Do a test of all emergency stop mechanisms on the machine as follows:
1. Apply power to the machine (
).
2. Push the start button (
). Do not cause the machine to operate. For example, do not start a
formula or operate the machine manually. It is not necessary to do the test when the machine
operates.
3. Operate an emergency stop mechanism (examples - button, kick plate, pull cord). If the mech-
anism operates correctly, the operator alarm comes on. Did this occur?
• Yes—Release the emergency stop mechanism if necessary. For example, if this is an
emergency stop button, turn the button clockwise to unlock it. Push the start button (
).
Do the test on a different emergency stop mechanism. Continue until you do the test on
all emergency stop mechanisms on the machine.
• No—An electrical component is defective. Shut down the machine. Do not let the ma-
chine operate until you correct the problem.
