Signal
Function
ON
When the control of the power supply section notices a +12V on this
signal, the start up cicled of the power supply carriages is activated.
The cicle is divided in two phases: the first contactor enables the power
transformer through power resistors, so that the possible current peak
at start-up is reduced; two seconds later, the second contactor is
excited, so that the transformer is directly fed. After an additional delay
of a second, the first contactor is released.
At this point, the start-up cicle is terminated and the STDBY line is
released.
STDBY
When this signal is at ground, the RF modules are forced on a RF mute
mode. The power supply section maintain on a stand-by position the
control bus untill the start-up cicle is ended, or when the ON signal is
not present, or at the end in all the coditions that are controlled by this
section that can affect the safety of the equipment. When all the
checked conditions are satisfactory the signal is released.
Alarm
When this signal is at ground the control unit checks all the devices
present on the bus to register and and manage eventual alarms. When
a signal or an alarm that affect the power supply section is revealed,
the processor that is used to control it orders to the line to go down so
to communicate to the control unit the event.
Tr+/Tr-
These signals are used for data communication. The levels meet RS485
standard , the speed is 115 kb/s. Please note that an eventual failure on
these signals doesn't affect the complex functionning of the equipment.
