EMX ULT-DIN DIN Rail Mount Vehicle Loop Detector Instruction Manual

EMX ULT-DIN DIN Rail Mount Vehicle Loop Detector

Instruction

The ULT-DIN vehicle loop detector allows for detection of metallic objects entering the field around an induction loop. This vehicle detector may be used in center, reverse and exit loop positions. The ULTRAMETER™ display feature makes set-up easy by displaying the optimum sensitivity setting required to detect a vehicle positioned near the loop. Ten sensitivity settings allow for fine adjustment of the detection level. The ULT-DIN provides relay contact outputs indicating vehicle presence and a second set of relay contact outputs providing auxiliary functions. The second output can be used for loop fault, pulse on entry/exit, or the EMX exclusive feature Detect-on-Stop™ (DOS®). The ULT-DIN features automatic sensitivity boost (ASB), delay, fail-safe/fail- secure and infinite or normal (5 min.) presence. Four frequency settings provide flexibility in preventing crosstalk in multi-loop applications.

Cautions and Warnings

This product is an accessory or part of a system. Install the ULT-DIN according to instructions from the gate or door operator manufacturer. Comply with all applicable codes and safety regulations.

Settings & Display

1. Sensitivity Setting
   The 10-position rotary switch allows for adjustment of the detection level. The sensitivity threshold increases from position 0 (lowest setting) through 9 (highest setting). Typical applications require a setting of 3 or 4. The rotary adjustment must be set to a specific/whole number. There are no half- settings.

2. Detect / Frequency Count (Red LED)

Power / Loop Fault Indicator (Green LED)

intermittently

Upon power-up, the detector initializes by automatically tuning to the loop. The green LED indicates that the detector is powered and operational.

ULTRAMETER™ Display
The display shows the sensitivity setting required to detect a vehicle near the loop. To use this feature, observe the display while a vehicle is moving into position near the loop, note the number displayed, then adjust the sensitivity setting to the displayed position. The display will adjust from 9 for a weak signal to 0 for a very strong signal. During normal operation, when a vehicle is not on or near the loop, the display is blank. The effects of cross-traffic interference can be observed on the display when the sensing area is vacant.

Frequency Count / Reset Button
Press the frequency count button and count the number of flashes on the red LED. Each flash represents 10 kHz. Following a frequency count cycle, the detector re-initializes.
DIP Switch
The DIP switch settings are explained on the next page.

The Automatic Sensitivity Boost causes the sensitivity to increase following initial detection. This feature is useful to prevent dropout when detecting high-bed vehicles. The sensitivity returns to its normal setting after the vehicle exits the loop. The decimal point on the ULTRAMETER™ display indicates ASB is on.

infinite presence mode causes the output to remain in detection as long as the vehicle remains on the loop. Normal presence mode causes the output to reset after 5 minutes. Do not use Normal presence mode for reversing loop applications.

The Delay mode provides a 2-second delay before activating Presence and Output B. Output B will not be activated if in Loop Fault mode. Do not use Delay mode for reversing loop applications.

The Output B relay is configurable for four possible modes. In Pulse on Entry/Exit mode, Output B will be activated for approximately 500ms when a vehicle is entering or exiting the detection zone. The Detect-On-Stop™ (DOS®) feature requires that a vehicle must come to a complete stop over the loop for a minimum of 1-2 seconds before Output B activates. Do not use the DOS® feature for reversing loop applications. In Loop Fault mode, Output B will trigger if a loop fault occurs.

The Fail Safe setting causes the ULT-DIN to activate the presence output in the event of a loop failure. The Fail Secure setting will cause the ULT-DIN not to activate the presence output in the event of a loop failure. Do not use Fail Secure for reversing loop applications.

DIP switches 7 and 8 are used to assign the loop operation frequency. The primary purpose of the Frequency Setting is to allow the installer the ability to set different operating frequencies for multi-loop installations and is recommended to prevent crosstalk/interference from adjacent loops.

Loop Installation

|
---|---

NEW SLAB POUR

Ty-wrap 1-1/4” PVC pipe to the top of the rebar in the size and configuration of the loop (ex. 4’ x 8’). Then ty-wrap the loop to the top of the PVC frame. This stabilizes the loop during the pour and separates it from the rebar.

|

SAW CUT EXISTING SURFACE

Cut 1” deep into the existing surface, place a 45° cut at the corners to prevent sharp edges from damaging the loop wire. Notch out for the “T” connection where the lead wire connects to the loop. Remove all debris from the finished cut with compressed air. Place the loop into the saw cut. Place backer material into the saw cut over the loop wire and pack tightly. Place a high-quality sealer over the saw cut to seal the surface.

| ****

RESURFACE ASPHALT

Saw cut the existing surface ¾” deep and place a 45° cut at the corners to prevent sharp edges from damaging the loop wire. Remove all debris from the finished cut with compressed air. Place sand over the loop wire to the surface and pack tightly. Lay new asphalt.

| ****

GRAVEL OR SOIL INSTALLATION

While this is not a recommended installation for most loops, it has been used successfully with proper preparation. Remove gravel or topsoil until reaching a stable base. Dig ~ 6-8” deep by ~ 6-8” wide. Fill halfway with sand and pack tightly. Place the loop into the trench and finish filling it to level with sand. Pack tightly and replace gravel or soil over top.

GENERAL INSTALLATION GUIDELINES**

·         Use EMX lite preformed loops for quick, reliable installations.

·         It is not recommended to install a loop near power lines (overhead or underground) or low-voltage lighting. If necessary near these power sources, place them at a 45° angle. Make the loop shape a diamond, not a square.

·         Never install a loop near inductive heaters.

·         If using a non-preformed loop, lead-in wire (wire from loop to detector) must be twisted a minimum of 6 turns per foot to avoid the effects of noise or other interference.

·         Detection height is approximately 70% of the shortest side of the loop.

For example: detection height for a 4’ x 8’ loop = 48” x .7 = 33.6”

Installation

1. Wire the ULT-DIN according to operator instructions. Refer to Wiring Connections for more information.

2. Configure the DIP switches according to preferences. Refer to Settings & Display for more information.
3. If using multiple loops or suspect crosstalk/interference from the environment, perform a frequency count on each detector to confirm that the operation frequencies are different.

·         Press the FREQUENCY COUNT / RESET button and count the number of flashes of the red LED. Each flash represents 10kHZ. Counts from 3 to 13 confirm that the detector is tuned to a loop.

·         If adjacent loops and detectors are utilizing the same or very similar frequency, configure DIP switches 7 and 8 on one of the devices. For example: Move one ULT-DIN to the low frequency setting and the second ULT-DIN to the high frequency setting.

4. Press the FREQUENCY COUNT / RESET button to re-initialize the detector and program the DIP switch settings.
5. Adjust the sensitivity setting to desired level to assure detection of all vehicle traffic.

TIP: ·  To test the sensitivity, without moving the inductive loop, drive a vehicle near the loop. When the vehicle is first detected by the loop, “9” will be displayed on the ULTRAMETER™ display. Position the vehicle over the loop where detection point is desired, take note

of the number displayed on the ULTRAMETER™ and change the sensitivity setting (10-position rotary switch) to match that number.

·         Move the test vehicle away from the loop to remove it from the detection zone (ULTRAMETERTM display should be blank).

·         Press the FREQUENCY COUNT / RESET button on the ULT-DIN.

·         Retest the product by moving the vehicle into and out of the detection zone to make sure

the set-up and location are working as intended.

6. Press the FREQUENCY COUNT BUTTON / RESET button to calibrate the ULT- DIN to the loop.
