Product Description

JUTAI LD200/202 double channels vehicle loop detector series, it with direction recognition function, and which is suitable for many single-channel entry and exit cases.

Connections

Indicates And Switch
Power Led: RED power LED indicates "Power ON"
CH1 Detecting Led: Continuously On: Indicates vehicle detection.
Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.
Blinking fast: Indicates loop is open circuit or too many twists after the loop.
CH2 Detecting Led: Continuously On: Indicates vehicle detection.
Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.
Blinking fast: Indicates loop is open circuit or too many twists after the loop.
Sensitivity Selection
Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting.
User can select 8 different setting by changing the setting of the dipswitch to different modes as in the dipswitch setting tables below. Dip switch 6, 7 and 8 for CH1 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.
Dip switch 3, 4 and 5 for CH2 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.


3. Switch 1=S1 : Channel 1 Loop Function Selection (10 way dip switch)
(1)(Switch 1) DIP 1 & DIP 2 Special Sensitivity Increase For Both Trailer (Both Channels).

(2)(Switch 1=S1) D3, D4, D5 and (Switch 2=S2) D1, D2 Setting Special Functions (Mode1, 2, 3 Direction Detection. Mode 4, 5, 6 Normal mode, two loop detection are separated)

(3)(Switch 1=S1) D6 & D7 & D8 and (Switch 2=S2) D3 & D4 & D5 Setting CH1 and CH2 Sensitivity Selection (Eight Levels Choices).

(4)(Switch 1=S1) D9 & D10 and (Switch2=S2) D6, D7 Setting Frequency (20 K to 100 KHz).

* Reset Button : Please note : The LD-200 must be reset every time a setting change is made to the Dip switches.

 Loop Installation
The loops are sealed using a "quick-set" black epoxy compound or hot bitumen mastic to blend with the roadway surface.

When installation, please keep the product plug and socket in the vertical direction

Application
JUTAI LD200/202 double channels vehicle loop detector series, it with direction recognition function, and which is suitable for many single-channel entry and exit cases.
JUTAI LD200/202 double channels loop detector connect to JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model : BR-110), and JUTAI long range RFID reader (Model : PUHF-9), combined with high temperature resistance loop coils (Model : JTHT-11), Which can be perfectly applied to single-channel entry/exit access control system.

The Working Principle As Follows
When the car from outside entry to Community or parking lot, Press the two loop coils at the same time, we will use JUTAI Double channels loop detector (LD-200/202) to trigger the UHF reader which at the entrance site; when uhf reader read the card ID, It will send ID to controller (AC-11) by wigand output; controller judge ID is valid, output relay signal to open gate barrier, and then car entry the community or parking lots, when car passed barrier gate, barrier arm will down automatically; (this part work with JUTAI Single channels loop LD100/102 for Safety and anti-smashing function) but when the car passed another uhf reader which connected by AC-11 also, this reader will not be triggered by loop detector again, and not send data to controller, so the software only have ENERY records; (Because the Direction Recognition Function of LD200/LD202 is enabled).

In contrast, when car Exit Community or parking lot, when the car passing the inside uhf reader, LD200/LD202 trigger the uhf reader, reader read card and send ID to controller, controller judge ID is valid,output relay signal to open gate barrier; then car EXIT the community or parking lots, when car passed barrier gate, barrier arm will down automatically; (this part work with JUTAI Single channels loop LD100/102 for Safety and anti-smashing function); But when car passed another uhf reader at exit, the double channels loop detector will not trigger signal again, system will only have EXIT records; (because the Direction Recognition Function of LD200/LD202 is enabled).

JUTAI LD-200/202 Double channels loop detector also can be used as two independent single channel loop detectors. This is suitable for a standard one-in and one-out parking lot, There is one barrier and one long range reader at the entrance, exit same also; one loop coils is used to trigger reader and read card, and the other loops coils is used for the barrier anti-smashing function, when the LD-200/202 as two independent loop detector application, from an economic point of view, which can reduce part of the hardware cost; (Enable the Independent working mode function of LD200/202).
