1 Display system
Intended users The display system must only be installed and connected up
by trained electricians or other persons who are familiar with
the installation of electrical equipment.
Specialist electrical training is needed for commissioning and
creating circuit diagrams. When active components such as
motors or pressure cylinders are controlled, parts of the
system can be damaged and persons put at risk if the display
system is connected or programmed incorrectly.
Proper use The display system is a programmable HMI, switching
closed-loop and open-loop control device for replacing relay
and contactor controls as well as for use as an HMI unit. The
display system must be properly installed before use.
The display module of the display system is protected to
IP 65 and does not normally need any special housing
protection. The rear units of the display system are designed
as mounting units and must be installed in an enclosure,
control cabinet or a service distribution board. Both the
power feed and the signal terminals must be laid and
covered so as to prevent accidental contact.
The installation must comply with regulations for
electromagnetic compatibility (EMC).
The power up of the display system must not cause any
hazards arising from activated devices, such as unexpected
motor startups or power ups.
Improper use
The display system should not be used as a substitute for
safety-related controls such as burner or crane controls,
emergency-stop or two-hand safety controls.
