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. When configured as a pulse output, the relay will output a pulse according to the pulse dura�on se�ng
and trigger event. The trigger event may be set to be either of the following:

x

Pulse on detect – the detector will give a pulse output on detec�on of a vehicle.

x

Pulse on un-detect – the detector will give a pulse output as the vehicle is un-detected.

The Pulse relay automa�cally operates in fail secure mode, while the presence output relay can be set to operate as fail
safe or fail secure.

In fail-safe, the output is the same in detect as it is with no power applied to the unit. Either a valid detect situa�on, or
a power failure / fault will provide a signal. In fail-secure, the output is the same in un-detect as it is with no power
applied to the unit. Only a valid detect situa�on will provide a signal.

4.4 Response times

The response time of the detector is the time taken from when a vehicle moves over the loop to when the detector
gives an output.

The response �mes of the PD17x have been adjusted to prevent false opera�on in electrically noisy environments, but
retain adequate response to vehicles in parking and vehicle access control applica�ons.

The response time will be propor�onal to the level of sensitivity, the level of the detect and the speed of the vehicle. In
other words, a fast moving large detect will respond quicker than a slow moving small detect. Also, if the sensitivity is
set very low, the point at which it crosses the threshold will be later than higher sensi�vity se�ngs. At maximum
sensi�vity however, the response �me is slower than other sensitivity levels to prevent false opera�on from noisy
environments.
