APPENDIX C
CONTROL SIGNAL ALGORITHM IN POTENTIAL CONTROL MODE
Both directions are locked (locked for entry and exit)
There is a high level at the contacts “Unlock A” and “Unlock B”, or a low level at the
contact “Stop”.
The both passage directions lock at this command.
The direction
А
is open (open for passage in the direction
А
)
There is a low level at the contact “Unlock A” while a high level is present at the
contacts “Stop” and “Unlock B”.
At this command the direction
А
opens till the low-level signal removal from the con-
tact
А
or until the command “Both directions locked” is received. The status of the di-
rection
В
does not change at that.
The direction
В
is open (open for passage in the direction
В
)
There is a low level at the contact “Unlock
В
” while there is a high level at the con-
tacts “Stop” and “Unlock
А
”.
At this command the direction B opens till the low-level signal removal from the con-
tact B or until the command “Both directions locked” is received. The status of the di-
rection A does not change at that.
Both directions are open (open for entry and exit)
There is a low level at the contacts “Unlock A” and “Unlock B” while there is a high
level at the contact “Stop”.
The both directions open at this command till the low-level signal removal from one of
the contacts A (B) or until the command “Both directions locked” is received.
Note!
For 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.
