EMX ULT-MVP™ Multi-Voltage Vehicle Loop Detector Instruction Manual

EMX ULT-MVP™ Multi-Voltage Vehicle Loop Detector Instruction

Instruction Manual

The ULT-MVP vehicle loop detector allows for detection of metallic objects entering the field around an induction loop. This detector automatically adjusts from 12 VDC up to 240 VAC which eliminates the installer’s need to match available power to an appropriately rated vehicle detector. 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-MVP 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 or pulse on entry/pulse on exit, or the EMX exclusive feature, Detect-on-Stop™ (DOS®). The ULT-MVP features automatic sensitivity boost (ASB), delay, fail-safe/fail-secure and infinite or normal (5 minute) presence. Four frequency settings provide flexibility in preventing crosstalk in multi-loop applications.

Cautions and Warnings

Settings & Display

Frequency Count / Reset Button

Press and release the frequency count button and count the number offlashes on the red LED. Each flash represents 10 kHz. Following a frequencycount cycle, the detector re initializes.

Sensitivity Setting

The 10-position rotary switch allows for adjustment of detection level.The sensitivity level increases from position 0 (lowest setting) through9 (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.

Detect / Frequency Count (Red LED)

Presence Detected on
No Presence off
Frequency Count flashing

Power / Loop Fault Indicator (Green LED)

Normal Operation on
Shorted or Open Loop fast flash
Previous Loop Fault flashes once

intermittently

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

ULTRAMETERTM Display

The display shows the sensitivity setting required to detect a vehiclenear the loop. To use this feature, observe the display while a vehicleis moving into position near the loop, note the number displayed, then adjustthe sensitivity setting to the displayed position. The display will adjustfrom 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 ofcross-traffic interference can be observed on the display when thesensing area is vacant.

DIP Switch

The DIP switch settings are explained on the next page.

Automatic Sensitivity Boost

DIP Switch 1

ASB Enabled on
ASB Disabled off

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 ULTRAMETERTM

display indicates ASB is on
Presence DIP Switch 2
Normal on
Infinite off

Infinite presence mode causes the output to remain in detect 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.

Delay DIP Switch 3
Delay On on
Delay Off off

Turning on the delay setting provides a 2 second delay before activating the relay after the sensitivity threshold is met. Do not use the Delay mode in reversing loop applications.

Output B

DIP Switch

Mode 4 5
Pulse on Entry on on
Pulse on Exit on off
DOS® off on
Loop Fault off off

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 DOS® feature for reversing loop applications. In Loop Fault mode, Output B will trigger if a loop fault occurs.

Fail Safe / Secure

DIP Switch 6

Fail Safe on
Fail Secure off

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

Frequency Settings DIP Switch
7 8
Low on on
Medium Low on off
Medium High off on
High off off

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 multiple 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 top soil 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 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 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 of6 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. Connect the 11 pin DIN rail socket or wire harness to the ULT-MVP and connect pins 1 and 2 (white  and  black  wire)  on  the  socket/harness  to  the  appropriate  power  source. Pin 4 (green wire) must be connected to earth ground for effective surge protection.
2.  Connect the loop wires to pins 7 and 8 (gray and brown wire).
3. Connect the operator wires to the socket/harness according to preferences and instructions provided by the operator manufacturer (see Wiring Connections).
4. Configure the DIP  switches  according to  preferences. Refer  to Settings &  Display for

more information.

5.    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 multiple 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-MVP to the low frequency setting and the second ULT-MVP to the high frequency setting.

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

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

of the number displayed on the ULTRAMETERTM 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 (ULTRAMETER™ display should be blank).

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

·         Retest the product by moving the vehicle into and out of the detection zone to make sure the setup and location are working as intended.
