presents a block diagram of the RPS power supply. The low frequency
oscillator produces an AC waveform which is frequency-selectable via the front panel
mounted selector switch. The frequency selection options are 16Hz, 20Hz and 25Hz.
The output of the oscillator is fed to the power amplifier. A front panel mounted
voltage adjust potentiometer varies the gain of the amplifier, increasing or decreasing
the output voltage.
The output of the power amplifier is fed to the output transformer. The output
transformer has three taps to select the nominal output voltage.
The monitoring circuit verifies that the RPS is producing ring voltage. If the
monitoring circuit is satisfied; relay K1 is operated, passing the RPS output to BRV
OUT, the BRV bus of the first peripheral shelf.
The RPS output also is passed through the released contacts of relay K2 to BRV IN,
which is connected to the BRV bus of an adjacent peripheral shelf. If an RPS also is
installed in the adjacent shelf, relay K2 is operated. However, the BRV bus of both
shelves are still bridged together through the contacts of relay K1 in the second RPS.
If both RPSs are functioning properly, relays K1 and K2 of both RPSs are operated,
separating the peripheral shelf BRV busses and passing the RPS outputs only to their
respective peripheral shelves.
