Page 4: Introduc�On
By making use of the DIP switches and push bu�on, the PD27x can be easily set up for the users applica�on needs. The unit also provides diagnos�cs by means of the Nortech DU100 and DU700 units. The PD27x provides visual outputs (LED’s) on the front of the enclosure to provide an indica�on of the state of the channels 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 PD27x Series dual 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 3.2.7 Frequency (switch 2 and 1) The frequency switches are used to shift the opera�ng frequency of the detector. This is primarily used to handle situa�ons in which more than one detector is used at the same site. The detectors must be set-up to ensure no crosstalk (interference) occurs between adjacent loops connected to different detectors.

Page 10: Front Panel Indicators
3.3 Front Panel Indicators The front panel indicators consist of a Red Power / Communica�on LED and one Green Channel LED. There are four possible conditions which are indicated by the LED’s. Idle condi�on – no vehicle is detected • Detect condi�on –... -
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
ASB operates as follows: When ASB is disabled, the un-detect level is dependent on the sensi�vity setting of the detector. Hence as the detector is made less sensitive, the un-detect level will reduce accordingly. When ASB is enabled the un-detect level is fixed irrespec�ve of the sensi�vity se�ng and will be equivalent to the un-detect level when the sensi�vity is on maximum se�ng. -

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. -
