Chapter 2 Safety Precautions and Elements
Risk Assessment of Machinery
For the risk assessment for the machinery, use the standards in ISO 12100, “Safety
of machinery - General principles for design - Risk assessment and risk reduction.”
Figure 3 on page 18 shows how a first generation MobileView 2711T terminal uses
an Allen-Bradley control relay with the enabling switches. The control system must
be designed for the safety level that results from the risk assessment of ISO 12100.
MobileView 2711T Terminal
Operation The MobileView 2711T terminal is a high-quality device that is equipped with
state-of-the-art electronics.
ATTENTION: To avoid malfunctions or damage through improper handling,
follow these instructions during operation.
• Do not operate the terminal if the cable is damaged or pinched. To avoid
damaging the cable, do not place the cable over or around sharp objects.
• When the terminal is not in use, hang the terminal on the mounting bracket
(ordered separately) or place inside a cabinet or enclosure.
• To avoid impact damage to the terminal, do not set the terminal on unstable
surfaces and keep the cable clear of high traffic areas.
~ If the terminal falls to the ground, verify that the emergency stop switch
and enabling switch remain operable before you use the terminal on any
machinery.
• To avoid damage to the operating elements, do not set the terminal on its
operating side.
• Do not set the terminal near heat sources and avoid direct sunlight.
• Do not expose the terminal to strong magnetic fields or excessive vibrations,
dust, or humidity.
• Use a soft, damp cloth with 50% water and 50% isopropyl alcohol to clean the
operating panel and operating elements. Do not use solvents, scouring agents,
or scrubbing sponges.
• Help prevent foreign objects or liquids from getting into the terminal. Check
the protective covers of the device regularly. Verify that all screws are firmly
tightened and that the housing and cable entrance are not damaged.
• Turn off the power supply before you remove the back cover of the MobileView
2711T terminal. When the back cover is removed, the terminal is sensitive to
electrostatic discharge (ESD).
• If the terminal exhibits any anomaly, have the unit thoroughly and fully tested
by the manufacturer or authorized repair dealer before you operate the
terminal again.
• Do not use sharp objects, such as a screwdriver, on the touch screen. Scratching
the surface of the touch screen can damage the display and compromise the IP
rating.
