Page 4: Introduc�On
The unit provides diagnos�c informa�on by means of the Nortech DU100 and DU700 units. The PD17x provides visual outputs (LED’s) on the front of the enclosure to provide an indication of the state of the channel, as well as the detector itself. -

Page 7: Approvals
The figure below shows the 11 pin connector on the rear of the PDx7x unit, as well as the DIN Rail clip for the DIN Rail housing version. The 11 pin connector plugs into a relay base that accommodates all of the wiring for the unit. A list of acceptable relay bases is given below. -
Page 8: Opera�Ng Procedure
3. Operating Procedure 3.1 Hardware setup The PD17x Series single channel parking detector is designed to be DIN rail mounted, with the controls and visual indicators at the front, and wiring at the rear of the enclosure. The power, loop and relay outputs are connected to the 11 pin relay base at back of the housing. -
Page 9: Front Panel Indicators
3.2.7 Sensitivity (switch 4 and 3) The sensi�vity of the detector determines the change of inductance necessary to produce a detect. The PD17x provides a selectable range of four sensi�vity se�ngs. Sensitivity is defined as a change in the inductance, with the PD17x it ranges from 0.01% to 0.1%, with 0.01% being the highest sensi�vity selec�on. - Page 10 indica�ng to the user that a fault has occurred. The detector must be power cycled or reset via the pushbu�on in order to clear the historical fault informa�on. In the event of a vehicle passing over the inductive loop, causing a detect, the Green Channel LED will light up indica�ng the presence of a vehicle and remain on for the dura�on of the detect.
-
Page 11: Opera�On
4. Operation The induc�ve loop vehicle detector senses the presence of a vehicle over an area defined by a loop of two or more turns of wire, laid under the road or pavement surface. This loop of wire is connected to the detector by a twisted pair of wires called a loop feeder. -
Page 12: Types Of Outputs
4.3 Types of Outputs The PD17x has one relay set to output presence on detect and the other to output a pulse on detect or undetect. When a relay is configured as a presence output, it will produce a con�nuous output during the presence of a vehicle over the induc�ve loop. -

OFF and Powerfail is turned on, as any drastic change in temperature could result in Powerfail starting up in the incorrect state. Nortech accepts no responsibility or liability in the event of incorrect behaviour caused by user interference. -
Page 14: Installa�On Guide
Only use CE approved 11 pin relay bases such as Nortech Part No. CTR119090 or equivalent. As an alternative to the 11 pin relay base, Nortech has an 11 pin wiring harness, Nortech Part No. 302FT0041, which can only be used in SELV voltage (less than 60 or less than 42 V ) applications. -
