Material damages to electronics due to missing
functional earth!
NOTICE
Ensure that the functional earth is connected, as otherwise the electronics can
be destroyed by a potential difference between the operating display and the
control cabinet PC if the voltage supply is interrupted to only one device and
established again. A direct connection of the functional earth between the
operator display and the control cabinet PC is optimal. If the functional earth is
connected to a neutral point, the control cabinet PC has to be connected to this
neutral point as well.
When installing CDI cables with a diameter of 7.4 mm, observe the
following bending radius:
●
Radius (when bended once while routing): 4 × cable diameter
●
Minimum bending radius (when moved permanently): 8 × cable
diameter
●
Optimum bending radius (when moved permanently): 12.5 ×
cable diameter
Operation breakdown due to mechanical forces on the CDI cables.
Avoid mechanical stress (tensile, compressive, torsional and lateral
forces) caused by plugs to the RJ45 socket.
Malfunctions caused by using inappropriate cables.
Use only cables listed in
chapter 5.4 "Connecting cables for CDI+
10.12.2 Connecting the control cabinet PC to multiple operating dis-
plays
Up to three operating displays of the type DR/DE can be connected serially to
the PR3 devices using the CDI+ interface. The operating displays only operate in
the “Clone” mode. The advanced mode can only be used if a second display is
connected to the display port. The touch function is always active on all
operating displays. Entries can not be blocked at individual operating displays.
