Assembly and Operation Manual
APPENDIX B
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 contact
А
or until the command “Both directions locked” is received. The status of the direction
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 contacts
“Stop” and “Unlock
А
”.
At this command the direction B opens till the low-level signal removal from the contact B
or until the command “Both directions locked” is received. The status of the direction 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.
