5.0.5 Front Panel Mimic Display
The front panel display is a densely integrated array of LEDs and switches that
comprise an important part of the user friendly interface. A great deal of human
engineering has gone into the design of this membrane panel. A full complement of
alarm indicators are provided along with the mimic display which shows the switch
positions of the redundant system. Four separate navigation buttons along with a sep-
arate “Enter” button allow the user to easily navigate the firmware menu on the Vacu-
um Fluorescent Display. Separate buttons have been provided for frequently used
functions further enhancing the controller’s ease of use.
5.1 Control Cable Considerations
The RCP series of redundant controllers is designed to drive negative 28 VDC latching
style transfer switches. Latching means that the switch has a self cutoff and does not
require continuous current consumption. Some commonly used waveguide transfer
switches used in Paradise Datacom Redundant Systems are given in Table 5-1.
As Table 5-1 shows, the switch drive current is dependent on the frequency band
which determines the physical size of the switch motor. Therefore the system designer
must consider the resistive cable losses when choosing a control cable length.
Similarly, the system designer must ensure use of the proper cable insulation for the
particular installation. Paradise Datacom uses both Standard Service and Burial Grade
for redundant system control cables. Standard Service cable has a PVC jacket which is
ultra violet ray (UV) stable in outdoor use. However, Standard Service cable should not
be immersed in water or be buried underground for long periods of time. For such
applications, Burial Grade cable should be installed.
The RCP controller sources +26 VDC @ 5 Amps maximum to the transfer switch. A
typical -28 VDC waveguide switch will operate over a range of -20 to -30 volts. There-
fore, the minimum voltage required at the waveguide switch is -20 VDC. Using this as
a design guideline, the control cable should be sized so that it does not drop more than
6 VDC from the controller to the switch.
