Assembly and Operation Manual
Potential control mode
The mode is used for speed gate operation with ACS-controller. The outputs of the ACS-controller
are to support potential control mode. Speed gate operation in potential control mode is described
in Table 8.
Control signal duration at sending control command to control inputs is to be not less than 100 ms.
The passage waiting time is equal to control signal duration, i.e. that if by the moment of passage
completion in the permitted direction, there is a low-level signal at the input of this direction, the
speed gate remains open in this direction.
Control command sending algorithm is given in Appendix 2. Sending a low-level signal to Stop
input, both directions are locked for signal duration time independently of signal levels at Unlock A
and Unlock B inputs. Removing low-level signal from Stop input, the directions shift into the modes,
according to signal levels at Unlock A and Unlock B inputs.
Note:
When the speed gate is operated from the ACS, high level of the control signal corresponds
to the open contacts of the controller output relay or to the closed output transistor. Low
level of the control signal corresponds to the closed contact of the controller output relay or
to the open output transistor.
5.2.7 Speed gate operation algorithm
Speed gate operation algorithm in pulse control mode in case of single passage in one of the
directions:
1. A command (control signals combination) for single passage performance in one of the
directions is sent from the control device (RC-panel, WRC, ACS-controller) to the control board
inputs.
2. The microcontroller on the control board processes the received combination of signals and
creates a command for the swing panels motor drive to open the passage. The Time of
holding in unlocked state (8 seconds by default) countdown begins.
3. The speed gate swing panels open in the chosen direction. The user can pass through the
speed gate in the chosen direction.
4. Any movement detected in the passageway is registered as a completed passage. PASS A or
PASS B relay output, corresponding to the passage direction, is activated for 80 ms. User's
location in the passageway is monitored by the intrusion detectors.
Note:
In order to prevent contact with the swing panels, the speed gate is equipped with the
danger zone detection. When user enters the danger zone, the swing panels moving
(opening or closing) is blocked. Danger zone range varies depending on the swing panels
dimensions.
5. After the user passes through the open swing panels he gets into a safe zone (zone, in which it
is impossible to get in contact with the swing panels) and the control board microcontroller
sends a command for the motor drive to close the swing panels. The swing panels get closed.
6. If at the moment of passage performance by the first user, another user's passage has been
authorized in the same passage direction, the swing panels will not get closed and the new
user will be able to follow the first one.
7. If at the moment of passage performance, another user's passage has been authorized in the
opposite passage direction, then after the first user's passage completion the swing panels
will be closed and open in the opposite direction for the second user to pass.
Note:
In order to increase throughput rate, arrangement of separate passage lanes for each
direction is recommended. Passage directions for each passage lane can be displayed on
the front-end indication blocks.
8. If the user does not enter the passageway during the Time of holding in unlocked state, the
swing panels will close the passage lane.
