Section 8: Maintenance Switch Controller
8.0 Introduction
Teledyne Paradise Datacom offers the option of utilizing the RCP2-1100 controller as
a Maintenance Switch Controller (RCP2-MAINT), which controls the position of a
single waveguide switch.
A Maintenance Switch Controller is typically connected to the switch drive via a
single cable. With systems using amplifiers of certain high power levels, the controller
could also be connected to the system SSPAs, so that the output of the amplifiers can
be temporarily muted during switchover to prevent arcing in the transmission line.
8.1 Operation Modes
The Maintenance Switch Controller controls the position of a switch at the output of the
connected amplifier or amplifier system. The position of the switch determines whether
the output signal of the amplifier or amplifier system is directed to a dummy load (the
maintenance position), or to the system output.
8.1.1 Directing the Output Signal to the System Output
When the operator presses the POS1 key on the controller front panel, the switch is
set to its primary position. The LED on the POS1 key will illuminate and the LEDs in
the mimic path display will show the signal directed to the system output. See Figure
8-1.
8.1.2 Directing the Output Signal to the Dummy Load
When the operator presses the POS2 key on the controller front panel, the switch is
set to its secondary position. The LED on the POS2 key will illuminate and the LEDs in
the mimic path display will show the signal directed to the termination. See Figure 8-2.
