5.6.4.6 Detection Fault Monitor

The detector has a fault monitor function. In the default mode, the detector will generate a

fault output (equivalent to a permanent detect) if the detector has not registered an

activation for a period of twenty hours.

This duration can be adjusted to a user defined value by setting DIP Switch 7 to ‘1’ (On)

and then using the terminal command DFM (reference section 7.7.4).

5.6.4.7 Detector Hold Time

The detector continues to hold the detector output for a default period of 600mS after

actual object detection has ceased. This can be adjusted to an extended period of

2000mS by setting DIP Switch 5 to ‘1’ (On).

5.6.4.8 Installation and Commissioning Guide

Once the detector has been installed the crossing coverage must be tested, this is done

by walking towards the detector.

For ease of use when testing with only one person the ‘Inline Installation Assistance

Cable’, can be used to allow the detect LED to be more visible. The user should

reference Table 9-1 - p105 for part numbers.

(1) From a standing position several feet back from the kerb, walk along each dotted

white line either side of the crossing towards the detector.

(2) The detector should start to detect as you step off of the kerb until you get near to

the opposite side in both cases. If this is not the case re-align detector and start

perform step (1) again.

(3) Again from a standing point several feet back from the kerb, walk the centre of the

crossing towards the detector.

(4) The detector will probably pick you up before you leave the kerb, this is perfectly

normal, and should detect almost all the way across.

(5) Repeat these steps for the opposite detector to ensure the whole crossing is

covered.
