Page 5: Introduction
INTRODUCTION The PD160 Enhanced Series Single Channel Inductive Loop Vehicle Detector is a microprocessor based detector designed specifically for parking and vehicle access control applications. It is suited primarily to complex multilane access control and counting applications. Using the most up-to-date technology, the PD160 has been designed in order to meet the requirements of a vast number of parking applications (in terms of operating conditions and options available to the user). -

Page 9: Operating Procedure
OPERATING PROCEDURE Hardware Set-Up The PD160 Enhanced Series single channel parking detector is designed to be shelf or 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 all connected to the single 11-pin plug, which is mounted at the rear of the enclosure. -
Page 10: Idle Display
If the detector is operating close to either limit, it is possible that either the frequency drift caused by environmental changes or the shift in frequency caused by a large %∆L/L detect will cause the frequency to go outside the limits and cause a retune. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 10 of 39... -
Page 11: Automatic Frequency Selection
3.2.2.1 Automatic Frequency Selection The PD160 Enhanced Series introduces the new Automatic Frequency Selection (AFS) which is turned on by default. This setting allows the detector to briefly evaluate all eight frequency shifts and select the best frequency offset available. It weighs up each selection based on where the frequency is located within the operational range, the signal strength, and the level of detected noise. -
Page 12: Sensitivity
When the vehicle leaves the loop and the detection is lost, the sensitivity level reverts to the pre- selected level. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 12 of 39... -
Page 13: Presence
(Permanent or Limited) 3.2.5 Relay The PD160 Enhanced Series provides user defineable outputs on each relay. The detector setup allows for relay outputs to be generated in the event of a vehicle entering, being present on or exiting the loop. -
Page 14: Relay Pulse Width
The delay time may be applied on any sensitivity level and may be different on each relay. It may also be used on either presence or pulse output. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 14 of 39... -
Page 15: Output Polarity
The max value will show the largest percentage change noted while the min value will show the smallest peak value of any one vehicle detected. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 15 of 39... - Page 16 This could be due to start-up conditions but is also noted at higher sensitivity levels at the extreme high and low inductances. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 16 of 39...
-
Page 17: Reset
Every setting change done by the user is saved when the unit loses power. For this reason, this Factory Reset sub-menu restores all the settings to the factory defaults for the specific model after asking for confirmation. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 17 of 39... -
Page 18: Power Fail
If Powerfail is used in conjunction with AFS and there is a concern of a channel going into fault, use AFS to select the best band and then turn it off to prevent the unit retuning on recovery. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 18 of 39... -
Page 19: Front Panel Indicator
Red Power LED will flash at the rate of 1Hz, out of sync with the channel LED, to indicate that the channel has recovered from a fault. This is to provide visibility if the channel is in detect at the time of viewing. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 19 of 39... -
Page 20: Principal Of Operation
The nature of the application determines the required sensitivity, which may be adjusted by means of the LCD Menu system on the front of the enclosure. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 20 of 39... -
Page 21: Types Of Output
Multiple sensitivity levels have been provided in the PD160 Enhanced Series Detector to cater for a wide range of parking and vehicle access control applications. The detection of small unwanted objects such as bicycles and trolleys may be eliminated by selecting lower sensitivity levels whilst high- bed vehicles and vehicle/trailer combinations will not lose detection by using Automatic Sensitivity Boost (ASB) option. -
Page 22: Pulse Output
Also, if the sensitivity is set very low, the point at which it crosses the threshold will be later than higher sensitivity settings. At maximum sensitivity however, the response time is slower than other sensitivity levels to prevent false operation from noisy environments. 304UM0001 Rev 00 PD160 Enhanced Series User Manual Page: 22 of 39... -
Page 23: Installation Guide
The PD160 Enhanced Series parking detectors are rated to operate from -30° C to +70° C but the rate of temperature change MUST not exceed 1°C per minut e. This system integrator MUST ensure that the housing used complies with this rate of temperature change requirement. -

Running feeder cables in their own slots, separated by at least 300 mm. For additional information on Crosstalk refer to the section “Crosstalk Prevention” in the DU100 Diagnostic Unit User Manual Nortech Document No. 895UM0001. For information about resolving Crosstalk refer to the “Theory of Application” section in Diagnostic Unit DU100 User Manual Document No. -
Page 25: Sensing Loop Geometry
It is good practice at time of installation to construct adjacent loops with alternate three and four turn windings.
