Monitoring Circuitry
The PS19 AC also limits the –48VDC output to feed the peripheral card slots.
All outputs, with the exception of the –48 VDC output, are regulated.
Voltage and current level monitoring circuitry checks each output of the PS19 AC
(including message and ring generator currents), and produces an alarm signal to the
Coral system main processor in the event of malfunction.
Monitoring circuitry verifies that each voltage output is within specification. If any
voltage deviates from specification, the monitoring circuitry produces an alarm signal
to the Coral system processor, causing the red alarm indicator to illuminate. Note that
the green power indicator of a PS19 AC remains illuminated at the same time as the
red alarm indicator.
