TTR-08A Electromechanical Tripod Turnstile
APPENDIX 2. Control signal algorithm at potential control mode
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.
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
”.
Both passage directions close at this command.
The direction A is open (open for passage in the direction A)
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 A opens up to the low-level signal removal from the contact
A or until the command «Both directions locked» is received. The status of the direction B
does not change at that
The direction B is open (open for passage in the direction B)
There is a low level at the contact “
Unlock B
” while there is a high level at the contacts
“
Stop
” and “
Unlock A
”.
At this command the direction B opens up to 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
”.
Both directions open at this command up to the low-level signal removal from one of the
contacts
A
(B)
or until the command «Both directions closed» is received.
