EMX ULT-MVP-2 Multi Voltage Vehicle Loop Detector Instruction Manual

EMX ULT-MVP-2 Multi Voltage Vehicle Loop Detector Instruction Manual

The ULT-MVP-2 two channel vehicle loop detector senses metallic objects near 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 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-2 provides relay contact outputs indicating vehicle presence for each channel separately and AB logic for direction indication. The relay output for each channel may be set for pulse or presence, or the EMX exclusive feature, Detect-on-Stop™ (DOS® ). The ULT-MVP-2 features automatic sensitivity boost (ASB) and infinite or normal (5 minute) presence. Four frequency settings provide flexibility in preventing crosstalk in multi-loop applications.

Settings & Display

Channel Set-Up / Reset Button

Press and release to enter/exit channel set-up mode and re-initialize the detector.

Sensitivity Setting

The 10-position rotary switch allows for adjustment of detection threshold.
The sensitivity level 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, during channel set-up mode. There are no half settings.

Channel 1 Detect Indicator

Channel 2 Detect Indicator

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. The effects of cross-traffic interference can be observed on the display when the sensing area is vacant.

• During normal operation, when a vehicle is not on or near the loop, the
  display will show a green segment rotating counterclockwise.

• When a loop fault occurs, the display will show one segment defined in the Loop Fault Indicator table below to describe the loop fault.

• When the channel set-up button is pressed, the current settings for the channel selected by DIP switch 1 will flash on the ULTRAMETER™ display according to the Channel Settings table.

DIP Switch
The DIP switch settings are explained .

Channel select, DIP switch 1, determines which channel’s sensitivity level is displaying on the ULTRAMETERTM display.
This switch also controls which channel set-up will be modified when pressing the channel set-up button.

DIP switch 2 allows the output relay to be configured for presence or one second pulse on entry operation.
When set to presence, the output relay remains activated while the vehicle is present on the loop. This mode may be set separately for each channel. AB Logic mode does not work in Pulse mode.

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 the relay activates. This mode may be set separately for each channel. Do not use DOS®feature for reversing loop applications.

AB Logic mode is capable of determining the direction of travel. If a vehicle enters the channel 1 loop and then proceeds to the channel 2 loop, the channel 1 relay contact will close only when the vehicle crosses over the channel 2 loop and vice versa. This mode is not channel specific and if turned on applies to both channel 1 and 2.

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. This mode is non-channel specific and if turned on is applied to both channel 1 and 2. Do not use Normal presence mode for reversing loop applications.

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. This mode is not channel specific and if turned on is applied to both channel 1 and 2. The decimal point on the ULTRAMETER™ display indicates ASB is on.

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 cross talk/interference from multiple loops.
Frequency is non-channel specific and is applied to both channel 1 and 2.

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 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. Connect the 11 pin DIN rail socket or wire harness to the ULT-MVP-2 and connect the 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 channel 1 loop wires to pins 7 and 8 (gray and brown wire) and channel 2 loop wires to pins 10 and 11 (pink and violet 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 non-channel specific DIP switch settings. (DIP switch settings 4 through 8 are non-channel specific.)
   TIP: To check current channel specific configurations, press the CHANNEL SET-UP button.
   The current settings for the channel selected by DIP switch 1 will flash on the ULTRAMETER™ display according to the Channel Settings table. (See Settings & Displays).

5. Set DIP switch 1 to the channel being changed. DIP switches 2 and 3 correspond with channel specific settings.

6. Press the CHANNEL SET-UP button to enter channel set-up mode. The display will continuously rotate through the settings for the selected channel: Channel (C), Sensitivity (S), Loop Frequency (F), Pulse/Presence (Pu), and Detect-on-Stop™ (d).
   TIP: To exit channel set-up, re-press on the CHANNEL SET-UP button. If the decimal point light is not on, no channel settings will be changed by exiting.

7. Configure DIP switches 2 and 3 according to preferences for this channel. If a change is made, the decimal point light on the ULTRAMETER™ display will turn on.
   TIP: If a DIP switch is already in the preferred on/off position, move the DIP switch out of the preferred configuration and back, the decimal point light on the ULTRAMETER™ display will turn on.

8. Press the CHANNEL SET-UP button to store channel settings.

9. Repeat steps 2 through 8 for the second channel.

10. Adjust the sensitivity setting to desired level to assure detection of all vehicle traffic.

    • To test the sensitivity of a channel’s loop, move DIP switch 1 to that channel so that the display will show that loop’s detection level. Drive a vehicle, without moving the sensing loops, near that channel’s 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™. Move the test vehicle away from the loop to remove it from the detection zone (ULTRAMETER™ display should be blank).
    • Press the CHANNEL SET-UP button and change the sensitivity setting (10-position rotary switch) to match the number that was on the ULTRAMETER™ display at the point of desired detection.

11. Press the CHANNEL SET-UP button to configure new sensitivity and exit programming mode.

    • 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.

12. Repeat steps 10 and 11 for the second channel.

Troubleshooting

• Refer to the indicators in the Settings and Display section to determine the channel of the LED to determine which loop is open/shorted.
• Check  the  loop resistance with a multimeter to confirm  a  reading between  0.5  ohms  and  5  ohms. If reading is outside of  this  range,  replace  the  loop. The reading should be steady.
• Check loop connections to terminals. Verify that splices are properly soldered and sealed against moisture.
