1.3 The Deceleration Angle
It is used to set the angle at which deceleration begins in the opening process. The
angle is 0 degree when the barrier gate is opened in place(in horizontal position)
and 90 degrees when it is closed in place(in vertical position). This parameter
indicates that deceleration begins when the barrier gate is opened to this angle. If
the boom shakes after it is opened in place, users can reduce this value. (Chapter
2.3 has the similar operation)
1.4 The Angle of Low-speed Area
It is used to set a low-speed area in the opening process. When the opening angle
reaches the set angle, the barrier gate will run at the end speed that chapter 1.5 set
until it is opened in place. If the value is 90, the function is invalid. If the boom
shakes after it is opened in place, users can reduce this value appropriately.
(Chapter 2.4 has the similar operation)
1.5 The End Speed
This is the minimum speed at which the barrier gate is opened in place. The barrier
gate will run at the this speed until it is opened in place. If the parameter is set too
large, the boom will shake when it is opened in place. (Chapter 2.5 has the similar
operation)

4.4.4. Relay output mode
The control board has two limit output relays. Users can set different output modes to
meet different application requirements.
Limit output: when the barrier gate opens to up limit position, the open relay will
close; when the barrier gate closes to down limit position, the down limit replay will
close; during the barrier gate opening or closing or stopping, these two relays are
disconnected. This function can be used with the system to monitor the status of the
barrier gate.
Alarm for boom swinging away: in this mode, "infrared signal input" and "GND"

14
interface are used as the signal interface of boom installation. If they are
short-circuited, it means that the boom works normally; if disconnected, it means that
the boom swings away. When the boom swings away, the barrier gate will open to up
limit position automatically and after then the up limit replay will stay in closing
status. When the boom is installed correctly and work normally (the signals are
short-circuited) again, the up limit replay will work normally.
Notice: This function needs to be equipped with inductive switch for detecting the
status of the boom.
Alarm against artificial lifting boom: in this mode, the up limit relay is used as an
alarm signal output. When the barrier gate closes at down limit position, if the boom
is artificially lifted up to a certain angle, the up limit relay will be closed for 15
seconds as an alarm output. An external alarm can be connected for alarm.
Down Limit Pulse Signal :After the boom runs to down limit position, the down
limit relay will send closing signal for a second. This function can be used as the
opening signal for the other barrier gate or other control system. The up limit replay
was closed when boom falls down, the signal during boom falling down and boom at
down limit position can be used as R&G light signal, or used for detecting the barrier
gate running status.
4.4.5. Buffer time for boom from closing to opening
Pressing open button in the process of closing, this parameter is used to set the buffer
time of the controller from receiving the command to starting to open.
4.4.6. Buffer time of barrier gate stopping
Pressing stop button in the process of barrier gate opening or closing, in order to
make the barrier stop smoothly, set a buffer time. This time is the time from the
barrier gate receiving the stop command to stopping completely.
4.4.7. Open the barrier gate by remote control to enter the motorcade mode
Open the barrier gate by remote control to enter motorcade mode directly. At this
time, the loop detector is invalid until closing the barrier gate. Closing barrier gate
both by wire control and by remote control can exit the motorcade mode. Opening the
barrier gate by wire control does not enter the motorcade mode. The default is "OFF".
Tip: When it is set to "OFF" in the up limit position, long press the "UP" button of the
remote controller for 4 seconds can also enter the motorcade mode; or pressing
"STOP" button on the controller with the program version of "10824" or above at the
up limit position can also enter this mode.

15
4.4.8. Valid time of loop detector signal
In the process of opening or up limit position, the duration time of the loop detector
signal needs to exceed the setting time, and the auto-closing action will be executed
after the loop detector signal disappears, avoiding that the loop detector signal is too
short and triggers the auto-closing action to hit the vehicles. The default time is
200ms. Range: 100ms-900ms.
4.4.9. Beep of Loop detector signal
There is loop detector signal (there is vehicle on the loop wire) when boom is at up
limit position, the buzzer will emit a hint tone. "ON" has a sound, and "OFF" has no
sound. “ON” is default.
4.4.10. Failure angle of loop detector anti-smashing
During the closing process, when the boom arrives at the setting angle from the
horizontal level, it will not respond to the signal of loop detector, to prevent vehicle
from being followed by other vehicles, and can also prevent the misoperation of the
loop detector from triggering the opening of the barrier gate. The default value is 5
degrees.
4.4.11. Failure angle on obstacle
During the closing process, when the boom arrives at the setting angle from the
horizontal level, if the boom meets on obstacle, it will not respond to barrier gate
opening. The default value is 10 degrees.
4.4.12. Switching angle of R&G light
When the boom opens to the setting angle, the relay of R&G light will close. The
default value is 60 degrees.
4.4.13. Wire control signal type measurement
"Infrared photocell", "loop detector/radar” and "stop" signals of the wire control
interface can be set to normal open input and normal close input, and the default is
normal open input.

4.7. "Regular Menu" Command Explanation:
F-02 Boom up deceleration position
It is used to set the starting position of deceleration in the process of boom lifting up.
The unit of angle is 0 degrees when the barrier gate is in the horizontal position and
90 degrees when it is in the vertical position. This parameter indicates that the barrier
will start to decelerate when the boom lifts up to this angle. If the boom shakes when
lifting to up limit position, this parameter can be reduced.
F-03 Boom down deceleration position
It is used to set the starting position of deceleration in the process of boom falling
down. The unit of angle is 0 degrees when the barrier gate is in the horizontal
position and 90 degrees when it is in the vertical position. This parameter indicates
that the barrier gate will start to decelerate when the boom falls down to this angle. If
the boom shakes when falling to down limit position, this parameter can be increased.
F-04 Low-speed running angle of boom up
