2.2.3 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 (see EN 60204-1). The
wiring of the direct opening action switching contacts must satisfy the category (per EN ISO 13849-1) determined
during the machine's risk analysis (per EN ISO 12100:2010).
The gray stop button meets all mechanical requirements of EN ISO 13850 and differs only in the color of the
emergency stop switches.
Warning!
•
Handheld control devices with a gray stop button that are not connected to a machine should
also be stored separately. This is to prevent confusion with functional equipment in emergen-
cies.
•
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 control device is not a substitute for an 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 section
"Standards and certifications" on page 118
for additional important information
about the stop button.
2.2.4 Handwheel
If the Mobile Panel is equipped with a handwheel, then it will be evaluated by software and can be transfered to
the controller in VNC mode via the RFB extension.
400 pulses are counted per revolution. A clockwise rotation of the handwheel increments, a counterclockwise
rotation decrements the counter value 0 to 4294967295 (32-bit value).
Key features:
•
4 pulses/notching
•
100 notchings/revolution
Information:
•
It is not possible to reset the handwheel value.
•
If the Mobile Panel falls to the floor, the mechanical position of the rotary knob must be checked.
If necessary, the control knob can be reattached by pushing it into place from the top.
2.2.5 Illuminated pushbutton
If the Mobile Panel is equipped with an illuminated pushbutton, then it can be evaluated using software. On the
Mobile Panel 7151, the button or LED can be read or enabled by the Control Center or a program using the
Automation Device Interface (ADI library). On the Mobile Panel 7120, 7121, 7140 and 7150, the button or LED can
be transferred to the controller or switched via the RFB extension in VNC mode (for the hardware numbers of the
3.6 "Key and LED configuration"
).
