Mobile Panel 40/50 User's manual V1.80
2.2.4 Stop button
The stop button has a dual-circuit design with normally closed contacts.
The gray stop button on the Mobile Panel satisfies the requirements of
EN
ISO
13850. It must be able to trigger a
category 0 or category 1 stop in accordance with the risk assessment of the
machine
. The wiring of the positively
driven N.C. switching contacts must satisfy the category (according to
EN
ISO
13849-1) determined during the
machine's risk assessment (according to
EN
ISO
14121-1).
The gray stop
switch
has essentially the same function as the red-yellow emergency stop. Its color is intended to
help prevent the emergency stop from being used if the hand terminal is disconnected when a hazard occur (since
the emergency stop has no effect when the hand terminal is unplugged).
Warning!
Handheld
control
devices with a gray stop button that are not connected to a
machine
should be kept
out of view in order to prevent confusion with functional devices in the event of emergency.
Resetting the stop
device
is not permitted to result in an uncontrolled restart.
The stop button is not a substitute for
safety
equipment.
The stop button on the handheld
device
is not a substitute for the emergency stop
switch
directly on
the
machine
. Certain mechanical faults in the stop button
can
only be detected when the button is
actuated. In the event of severe impact to the
device
(e.g. the
device
is dropped), the stop button must
be inspected to ensure functionality. In addition, stop functionality must be tested periodically (every
6 months) by actuating the stop button.
See
"Standards and certifications" on page 88
for additional important information about the stop
button.
