MVP-D-TEK Vehicle Loop Detector 9 Volts DC to 240 Volts AC Operating Instructions
We have designed the new MVP-D-TEK vehicle loop detector with the following objectives in mind: 1. Compact package to allow easy installation into small operator housings. 2. All the controls are accessible from the outside for easy installation and operation. 3. Integral loop conditioner is provided, to enable detector operation with marginal loops. 4. Provide all the features and controls necessary for a variety of applications. 5. Use metal housing for maximum durability and RF blocking. 6.
Technical Specifications Power: Current Consumption: The MVP detector operates across the 9V DC - 240V AC power range. 19.2 mA @ 9 VDC 18.8 mA @ 12 VDC 17.3mA @ 24 VAC 9.5 mA @ 24 VDC 13.5 mA @ 115 VAC 11.0 mA @ 237 VAC Temperature: Environmental Protection: Enclosure: -40F to + 180F Circuit board is conformally coated Extruded anodized aluminum, Height = 3.25 inches 83 mm Width = 2.56 inches 40 mm Depth = 3.
Front Indicators 1. Green Led is ON - the detector is powered. 2. Red Led is ON - the detector detected a vehicle 3. Green Led is Blinking - the loop failed and is shorted or disconnected 4. Green Led is Blinking with two consecutive fast blinks - the loop failed in the past and now is working correctly. 5. Red Led is Blinking at the start of a vehicle detection - the Filter function is ON 6. Red Led is Blinking at the end of a vehicle detection - the Extend function is ON 7.
DIP - Detector Functions 1. Presence function is provided always by the presence relay output on pins 5, 6, and 10. These outputs are active when the detector detects a car. If there is a need for an additional presence output the Relay 2 can be configured as a second presence output by setting DIP 1 to ON position. 2. Pulse function is provided by the Relay 2 output on pins 3, 9, and 11. To obtain pulse on Relay 2 set DIP 1 to OFF position. The pulse of about 0.
Trouble Shooting Symptom Possible Cause Correction Green indicator is not ON No input voltage 1. Check voltage on pins 1 and 2. 2. Replace internal fuse 3. Check wiring to detector Green indicator flashes Loop wire shorted 1. Check loop resistance on pins 7 and 8 it should be less or disconnected than 5 ohms and more than 0.5 ohms. Green indicator flashes with two consecutive fast blinks Loop wire was temporarily shorted or disconnected 1.
