Arrangement and Operation
1.4.1
Outputs
The unit controls actuating devices by switching voltage from its own contacts U
main
and U
backup
to the output terminals. Connecting external power supplies to the output terminals is prohibited and
can cause a unit fault.
The unit provides switching outputs (on, off, on and off alternately) under the given program in
accordance with control commands received via the polling loop as well as monitoring control
outputs and circuits connected to them.
Status of a switched off monitored circuit is defined by the value of voltage at the positive output
terminal relatively to the 0V terminal:
-
Normal: between minus 0.15 V and minus 1.125 V;
-
Open-Circuit Fault: less than minus 1.125 V;
-
Short-Circuit Fault: higher than minus 0.15 V.
Status of a switched on monitored circuit is defined by the value of monitored circuit current:
-
Normal: between 5 mA and 3 A;
-
Open-Circuit Fault: less than 5 mA;
-
Short-Circuit Fault: higher than 3 A.
Note:
If an output while being switched on is in the short circuit condition then it will not be
switched on. The output can be switched on in 15 seconds after the failure is repaired.
On detecting a short or open circuit failure in a monitored circuit, the unit sends an Output Open
or Output Short message respectively over the interface bus. When the monitored circuit returns into
the Normal status the unit sends an Output Restored message over the interface bus.
Conditions of the actuating outputs and the monitored circuits connected to them in the quiescent
mode are indicated by the “1” and “2” LEDs as shown in Table 1.4.1.
