Appendix B Control signal algorithm at potential control mode
Both directions are closed (closed for entry and exit) -
There is a high level at contacts “Unlock A” and “Unlock B” or there is a low level at contact “Stop”.
The both passage directions close at this command.
Direction А is open (open for passage in direction А)
-
There is a low level at contact “Unlock A” while a high level is present at contacts “Stop” and
“Unlock B”.
At this command direction А opens up to the elimination of low
-
level signal from contact А or until
the command «Both directions closed» is received, and the status of direction В does not chang
e.
Direction В is open (open for passage in direction В)
-
There is a low level at contact “Unlock В” while there is a high level at contacts “Stop” and
“Unlock
А”.
At this command direction B opens up to the elimination of low-level signal from contact B or until
the command «Both directions closed» is received, and the status of direction A does not change.
Both directions are open (open for entry and exit) -
There is a low level at contacts “Unlock A” and “Unlock B” while there is a high level at contact
“Stop”.
The both directions open at this command up to the elimination of low-level signal from one of the
contacts A (B) or until the command «Both directions closed» is received.
Note! For an ACS controller outputs:
•
low level — either contacts of the output relay are closed or the output transistor is open;
•
high level — either contacts of the output relay are broken or the output transistor is
closed.
