5.2.6 Turnstile control modes
There are two turnstile control modes – pulse and potential. In both modes the turnstile is
controlled by sending commands (i.e. control signals combinations) to
L
,
ST
and
R
control inputs
and to a special
FA
control input. Control command sending algorithm changes depending on the
The control mode is set either
ON
or
OFF
by
SA1 (SETUP)
switcher on the interface board (10).
Switcher location (Fig. 7). Shift the switcher into
ON
position to switch the turnstile into pulse mode.
Shift the switcher into
OFF
position to switch the turnstile into potential control mode.
Caution!
Shift the switcher with de-energized equipment only.
Pulse control mode
is used for turnstile operation from RC-panel, WRC and ACS controller with
the outputs supporting pulse control mode.
Control signal duration at sending control command to control inputs is to be not less than 100ms.
The initial passage waiting time is 8 sec., it is independent of control signal (pulse) duration.
The turnstile operation description for this mode is given in Table 5. Control command sending
algorithm is given in Appendix 1.
Potential control mode
is used for turnstile operation with ACS controller. The outputs of the ACS
controller are to support potential control mode.
Control signal duration at sending control command to control inputs is 100ms. minimum. The
passage waiting time is equal to low-level signal duration, i.e. if by the moment of passage
completion in the permitted direction, there’s a low-level signal on the input of this direction, the
turnstile remains open in this direction.
The turnstile operation description for this mode is given in Table 6. Control command sending
algorithm is given in Appendix 2.
By sending a low-level signal to
ST
input, both directions are locked in accordance to signal
duration time, independently of signal levels on
L
and
R
inputs. Removing low-level signal from
ST
input, the directions shift into the modes, according to signal levels on
L
and
R
inputs.
The turnstile operation at the
FA
control input is described in Sect. 5.3.2.
5.2.7 Turnstile mechanism operation algorithm
Turnstile operation algorithm at pulse control mode in case of single passage in one of the
directions:
1. Turnstile starting position - the drive is turned off, passage denial indicator is on, when you try
to turn the barrier arms more than 5° in any direction, the blocking device blocks the hub, an
alarm is turned on - passage through the turnstile is closed.
2. The command (combination of control signals) for single passage performance in one of the
directions is sent from the control device (RC-panel, WRC, ACS controller) to the interface
board inputs.
