The control mode is set by removal / installation of the jumper on a J1 connector on control
board. The J1 connector location is shown in Fig. 5. An installed jumper corresponds to
the pulse control mode. In order to switch to potential mode, uninstall the jumper. The
change of control mode will take place after switching on the turnstile.
Pulse control mode
The mode is used to control the turnstile with RC panel, WRC and CLB, outputs of which
support pulse control mode.
Duration of control signal during command issuing on operational control inputs should be
not less than 100mc. The passage waiting time is 5 seconds and it doesn’t depend on
duration of control signal (impulse).
Description of turnstile work in pulse control mode is described in Table 5 Procedure of
command issuing is described in Appendix 1.
By removal of low-level signal from special control input
Fire Alarm
, turnstile switches to
Fire Alarm,
mode and therewith all incoming commands of turnstile control are ignored
(see Clause 5.3.2).
During low-level signal issuing at the input
Fire Alarm
command
«Passage Denial»
is sent
and turnstile rotary mechanism is blocked.
Potential control mode
The mode is used to control the turnstile with CLB, outputs of which support potential
control mode.
Duration of control signal during command issuing on operational control inputs should be
not less than 100mc.
The passage waiting time equals the duration of control signal: if by the moment of the
passage in authorized direction at the entrance of this direction there is a low-level signal,
then the turnstile will stay open in this direction.
At the low-level signal inputting to the “Stop” input, both directions will lock for the time of
the signal duration regardless of the signal strength at the inputs “Unlock A” and “Unlock
B”. By the removal of a low-level signal from the “Stop” input, the directions will set to the
modes according to the signal strength at the inputs “Unlock A” and “Unlock B”.
Description of turnstile work in potential control mode is described in Table 6. Procedure of
command issuing is described in Appendix 2.
Note:
To organize single passages in potential control mode it is advisable to remove low-
level control signal from control input

5.2.7
Algorithm of the control mechanism
Procedure of turnstile work in the pulse control mode in case of a single passage in one of
directions:
1. From control unit (RC panel, WRC, ACS) on control board inputs comes a
command (combination of control commands) for execution of a single passage in
one of directions.
2. Microcontroller, fixed on the control board, processes the received signal
combination and forms a command to the turnstile control unit to unblock the rotary
mechanism. Turnstiles hold time counting starts in the blocked mode.
3. Control mechanism unlocks the rotary mechanism for the rotation in a chosen
direction. Passage in this direction becomes possible.
