MVP D-TEK

MVP D-TEK Overview

The MVP D-TEK multi-voltage vehicle detector makes it simple to manage your stock. All you need is one detector in your stock room and on your truck.

How do I test my loop and MVP D-TEK to make sure they are working?

1. Loop

1a. Loop resistance: Disconnect the loop wires from the D-TEK and make sure the resistance across the red and black wires is 0.5-5 ohms. A value outside this range means the loop is bad.

1b. Megger Test: There may be a break in the insulation of the cable. Perform a megger test from loop lead to ground. A good result is more than 100 megaohms.

2. MVP D-TEK

2a. While the MVP D-TEK has power and a connection to the loop, disconnect the output contacts (NC, COM, NO) from the operator inputs.

2b. To test the Presence relay, set digital multimeter to measure resistance in ohms and connect it to COM and NO contacts. That is pin 5 and 6 on the DIN rail socket (LD-11) or blue wire and yellow wire on the 11 wire harness (HAR-11).

To test Relay 2 use pins 3 and 9 on the DIN rail socket or orange and red wires on the 11 wire harness.

2c. The meter should read open (OL, INF). Move a metal tool over the loop. Verify the red LED turns on and the meter reads less than 10 ohms. If the red LED turns on and the meter is still showing open, the relay is defective. The readings will be in reverse if dip switch 4 is turned off, putting the device in fail secure mode.

11 Wire Harness Relay Test:

Why does my MVP D-TEK intermittently send an output signal when nothing should be triggering it?

Multiple Device Interference: Multiple loops near each other can cause false triggers. Flip the frequency switch on each MVP D-TEK to a different setting of low, medium, and high. After making the selection flip the other switch momentarily down to RESET in order to calibrate to the new frequency.

Damaged Loop Wires: Make sure there is an open circuit (OL, INF) between the black wire and shield wire, and also between the red wire and shield wire. Any other result indicates the problem is the loop.

High sensitivity: Reduce the sensitivity by turning the sensitivity dial counterclockwise 1 or 2 levels to see if this prevents the false triggers. Test to make sure the sensitivity is still high enough to trigger when a vehicle or other ferrous metal object is moving over the loop.

Overloaded power supply: Remove all other electronic equipment from the power supply that is powering the MVP D-TEK, or place it on its own power supply to make sure its power source is not overloaded.

Noise in the system: Make sure the loop shield wire and earth ground are connected to pin 4 to reduce noise. Make sure there are no underground or above ground power lines, or power transformers nearby the loop.

Why is my MVP D-TEK stuck always sending an output signal and the red light is always on?

There may be a problem with the loop.

Damaged Loop Wires: Perform a megger test from loop lead to ground, it should be more than 100 megaohms. Also, check loop connections to terminals. Verify splices are properly soldered and sealed against moisture.

Why is my MVP D-TEK green light flashing quickly?

This error code indicates a loop error. Typically, the loop wire is shorted or not connected.

Damaged Loop Wires: Disconnect the loop wires from the D-TEK and make sure the resistance across the red and black wires is 0.5-5 ohms. A value outside this range means the loop is bad.

Loop Wire Connection: Check loop connections to pin 7 and 8 on the DIN rail socket or the brown and gray wire on the 11 wire harness.

Reset Switch: Momentarily flip the RESET switch down. This will calibrate the device to the current environment and also save all dipswitch settings.

Why is my MVP D-TEK green light flashing slowly?

This error code indicates a loop error occurred sometime since the last reset. Typically, the loop wire was previously shorted or open circuit.

Damaged Loop Wires: Check the loop resistance with a multimeter to confirm a steady reading between 0.5 ohms and 5 ohms. A value outside this range indicates a problem with the loop.

Reset Switch: Momentarily flip the RESET switch down. This will calibrate the device to the current environment and also save all dipswitch settings.

Why is my MVP D-TEK not sending an output signal when something should be triggering it?

There may be a problem with the loop.

Low sensitivity: Increase the sensitivity dial by turning it a quarter turn clockwise. Make sure not to increase sensitivity too high or the device may be activated by objects outside of the desired range.

Damaged Loop Wires: Disconnect the loop wires from the D-TEK and make sure the resistance across the red and black wires is 0.5-5 ohms. A value outside this range means the loop is bad.

Why is my MVP D-TEK not sending an output signal even though the red light is on?

There may be a problem with the wiring or MVP D-TEK relay.

1. Verify you have the correct wiring from the loop to the MVP D-TEK relay to the operator.

2. MVP D-TEK

2a. While the MVP D-TEK has power and a connection to the loop, disconnect the output contacts (NC, COM, NO) from the operator inputs.

To test Relay 2 use pins 3 and 9 on the DIN rail socket or orange and red wires on the 11 wire harness.

DIN Rail Socket Relay Test:

11 Wire Harness Relay Test:

The MVP D-TEK red detection light is off but the output is activated.

Failsafe Mode: The device may be set to fail secure mode which switches the relay outputs, making normally closed act like normally open and vice versa. To enable failsafe mode, make sure dipswitch 4 is set to on.

Relay Sticking: The relay in the MVP D-TEK may not be switching states.

2a. While the MVP D-TEK has power and a connection to the loop, disconnect the output contacts (NC, COM, NO) from the operator inputs.

2b. To test the Presence relay, set digital multimeter to measure resistance in ohms and connect it to COM and NO contacts. That is pin 5 and 6 on the DIN rail socket or blue wire and yellow wire on the 11 wire harness.

To test Relay 2 use pins 3 and 9 on the DIN rail socket or orange and red wires on the 11 wire harness.

DIN Rail Socket Relay Test:

11 Wire Harness Relay Test:

The green power light on my MVP D-TEK is off, even though I have power wires connected to it.

Power Failure: Check the power supplied to the MVP D-TEK on pins 1 and 2 for the DIN rail socket or white wire and black wire for the 11 wire harness. Voltage should read between 12-240 VDC/AC.
