Safety Precautions and Elements
This section covers general safety precautions in addition to important information
on the power supply, emergency stop switch, and enabling switches used with the
MobileView Guard G750.
General Safety
It is important to follow the instructions in this document in all circumstances.
Failure to do so could result in potential sources of danger or the defeating of safety
features integrated in the terminal.
In addition to the safety instructions in this document, you must also use safety
precautions and accident prevention measures appropriate to the situation.
ATTENTION
!
Publication 2727-QS002E-MU-P
• Make sure interrupted processes can be properly restarted
after power failures or power dips. No dangerous
operating conditions must be allowed to occur, even
temporarily.
• In situations where faults occurring within the automation
system could cause personal injury or significant damage
to machinery and equipment, take additional external
safety measures to ensure the system remains in a safe
operating condition.
• Make sure unauthorized persons are not allowed to adjust
settings or make memory modifications that could lead to
dangerous situations.
• Test the functionality of safety-related parts (E-stop and
enabling switches) on a regular basis.
• If the MobileView terminal and controller do not
communicate using a point-to-point connection, keypad
data, for example, may transmit with a delay. Use of an
Ethernet switch between the MobileView terminal and
controller is recommended for a higher speed connection.
• Test safety-relevant parts after strong shocks to the
terminal (for example, if terminal is dropped on ground).
• When the MobileView terminal is used to operate the
machine/plant, ensure that the MobileView is the single
point of operation (C.F. ANSI/RIA 15.06).
• If you use a PC card with the MobileView, always make
sure the PC card is properly loaded. After a strong impact,
the PC card cover remains closed. Verify that card is
properly loaded to maintain a good electrical contact.
• When the MobileView terminal is used in manual mode
(for example, teaching of robot), insure robot moves at a
slower speed (C.F. ANSI/RIA 15.06).
