System Good Function
06057
-
The Sys Out signal (pin 26) provides information about the
general function of the converter. It can be used to monitor the
status of a single T Series converter, or can be linked with other
signals within a power system to drive one single-logic signal
for the status of the whole system by connecting the output Sys
Out of one converter to the input Sys In (pin 24) of the next one.
Low voltage (impedance) of the input and output has the
meaning of "system good". The first input of the system has to
be connected to Vo–.

Sys Out
The signal Sys Out is activated (low impedance), if the
following conditions are met:
No external fault
– the Sys In signal (pin 24) is logic low,
AND:
No faults monitored by the T Series converter, such as:
– Input overvoltage
– Input undervoltage (mains failure)
– Output overvoltage
– Output short circuit
– Internal overtemperature
– Internal circuit fault.

Equivalent circuit of Sys In and Sys Out
Signal output
The signal Sys Out (pin 26) has the meaning of “system good”.
It is built by an open collector transistor referenced to Vo–,
protected by a 62 V Zener diode.
– i/Vcr input error such as voltage < 2.5 V (rectifier type);
control voltage out of range 5.3 V > V cr > 14 V (battery
charger), or sensor not connected, open remote control
input.

The input Sys In (pin 24) can be voltage- or current- driven. To
trigger the internal comparator, the voltage at the Sys In pin
has to be < 6.2 V, if voltage-driven. If current-driven, the sink
current to Vo– has to be > 100 μA. An easy way to drive this
Vo–
relay necessary
input is achieved by means of an open collector transistor, or a
10 V CMOS interface.
Note: If only the internal status of a T Series converter should be
monitored, Sys In has to be connected to Vo–.
