Appendix 1. Operation algorithm at pulse control mode
“Always locked”
(locked for entry and exit) – active front at the
Stop
contact while there is a high
level at the
Unlock A
and
Unlock B
contacts. Both passage directions are locked at this command.
“Single passage in A direction
” (open for passage of one person in A direction) – active front at
“Unlock A” contact, while there is a high level at “Stop” and “Unlock B” contact. At this command
the passage direction A opens either for 5 sec. or until the passage has been made in this direction
or until the command “
Always locked
”, and the status of the passage direction B does not change
at that. The command is ignored if at the moment of its receipt the status of the passage direction
A is “
Always free
”.
“Single passage in B direction
” (open for passage of one person in B direction) – active front at the
contact “Unlock B” while there is a high level at the contacts “Stop” and “Unlock A”. At this
command the passage direction B opens either for 5 sec. or until the passage has been effected in
this direction or until the command “Always locked”, and the status of the passage direction A does
not change. The command is ignored if at the moment of its receipt the status of passage direction
B is “Free passage”.
“Free passage in A direction”
(open for free passage in A direction) – active front at the contact
“Unlock A” while there is a low level at the contact “Stop” and a high level at the contact “Unlock B”,
or active front is at the contact “Stop” while there is a low level at the contact “Unlock A” and a high
level at the contact “Unlock B”. At this command the passage direction A opens until the command
“
Always locked
” is received; the status of the passage direction B does not change at that.
“Free passage in B direction”
(open for free passage in B direction) – Active front is at the contact
“Unlock B” while there is a low level at the contact “Stop” and a high level at the contact “Unlock A”,
or active front is at the contact “Stop” while there is a low level at the contact “Unlock B” and a high
level at contact “Unlock A”. At this command the passage direction B opens until the command
“
Always locked
” is received; the status of the passage direction A does not change at that.
“Free passage”
(open for free passage in both directions) –
Active front is at the contact “Unlock A”
while there is a low level at the contacts “Unlock B” and “Stop”, or active front is at the contact
“Unlock B” while there is a low level at the contacts “Unlock A” and “Stop”, or active front is at the
contact “Stop” while there is a low level at the contacts “Unlock A” and “Unlock B”. Both directions
open at this command until the command “
Always locked
” is received.
Appendix 2. Operation algorithm at potential control mode
“Both directions are locked”
(locked for entry and exit).
There is a high level at the “Unlock A” and
“Unlock B” contacts or a low level at the “Stop” contact. Both passage directions are locked at this
command.
“A direction is open”
(open for passage in A direction). There is a low level at the “Unlock A”
contact while a high level is present at the “Stop” and “Unlock B” contacts. At this command the
direction A opens till the low-level signal removed from the contact A or until the “Both directions
locked” command is received. The status of the direction B does not change at that.
“B direction is open”
(open for passage in B direction). There is a low level at the “Unlock B”
contact while there is a high level at the “Stop” and “Unlock A” contacts. At this command the
direction B opens till the low-level signal removed from the contact B or until the “Both directions
locked” command is received. The status of the direction A does not change at that.
“Both directions are open”
(open for entry and exit in both directions). There is a low level at the
“Unlock A” and “Unlock B” contacts while there is a high level at the “Stop” contact. Both directions
open at this command till the low-level signal removed from one of the contacts A (B) or until the
“Both directions locked” command is received.
