Page 8: Description And Lay-Out Of Jumpers And Sockets
SA-ACU-SR User Manual The front panel of the module contains: • four LEDs, indicating the operating conditions of the power feeding circuits and the presence of the external clock signal; • the “2048 kHz IN” socket for the connection of the external clock source;... -
Page 9: Control And Configuration Of The Modules
The front panel of each device has LEDs indicating its condition. Each device has signal outputs connected to the common signal bus of the shelf. The SA-ACU-SR module has two relays and control circuits of their condition for the connection of the common bus to external voice and visual alarm signaling units. -
Page 10: Connection Of The Shelf To The Clock Source
The universal AccessGain platform has a possibility of synchronization of signals transmitted from the external clock source. The SA-ACU-SR module contains a unit designed to receive and process (supervise) clock impulses at a frequency of 2048 kHz. The socket for the connection of the external clock source is of a 75-Ohm BNC type. -
Page 11: Power Failure Alarm
SA-ACU-SR User Manual 3.7 Power failure alarm The front panel of the SA-ACU-SR module displays the status of the shelf power feeding. The A and B “–48V ” LEDs inform an operator about the status of primary and auxiliary power feeding circuits, respectively. In normal condition the LEDs are green, while in case of a power supply failure, the LEDs will be extinguished. -
