- Install Detector:
The detector must be installed in a convenient weatherproof location as close to the loop as possible. Installation location must choose to stay away from the heat source, it around other devices must maintain a distance of at least 10 mm (mustn't fix cling to the cabinet). A correct loop configuration and detector installation will ensure a successful inductive loop detection system. Loop of several important parameters include: loop figure, size, and turns, install methods (details as "Loop installation guide").
- Operation and Indication:
While the detector is tuning, the green Channel LED and red Power LED will be turn on. It remain about 2 seconds, then the green LED turn off. If a loop fault exists the Channel LED will come on and flash indicating a fault. If the fault is self-healing the detector will continue to operate. The green channel LED will also glow whenever a vehicle is detected passing over the inductive loop. The red Power LED at the top of the unit will remain on to indicate that the unit is powered.
- Output Relay：
The relay2 is pulse output. If DIP7 is "OFF" site, when a vehicle is detected passing over the inductive loop, the relay is energized( Pin3 and Pin4 is shorted) and de-energized ( Pin3 and Pin4 is opened) after 500ms. If DIP7 is "ON" site, when a vehicle is detected departing the loop, the relay is energized ( Pin3
and Pin4 is shorted) and de-energized ( Pin3 and Pin4 is opened) after 500ms.
The relay 1 is presence output. When a vehicle is detected passing over the inductive loop, the relay is energized( Pin5 and Pin6 are shorted) until the vehicle is detected departing the loop.
- Presence Time:
The presence time may be set to permanent presence or to limited presence.
In permanent presence mode the detector will continuously compensate for all environmental changes whilst there is a vehicle present over the loop, the presence mode is set with DIP8 Switch and is configured as follows: OFF:Limited Presence ( 10 minutes), ON：Permanent Presence.
- Reset Switch :
The detector automatically tunes to the inductive loop connected to it when the power is applied, whether on initial installation or after any break in power supply. Should it be necessary to re-tune the detector, as may be required after changing any of the switches or after moving the detector from one installation to another, momentary operation of the RESET switch will initiate the automatic tuning cycle.
