Trackside Infra-Red Lap Beacon - Stack Dash-2 User Manual

STACK Dash-2 Kart Logger

Trackside Infra-Red Lap Beacon

The ST544 infra-red lap beacon should be located as follows:
•
As near to the start-finish line as possible
•
At the same height as the on-kart detector
•
Level, so that it emits a horizontal beam towards the left hand side of the kart.
•
It must be between 2 and 30 meters (6 to 95ft) from the kart when the kart passes it.
•
There must be no other Infrared beacons of any type within 4 metres.
Avoid positioning it so that the sun is directly behind it when it is being used.
Where the unit is to be used for lengthy periods in very hot, sunny conditions, it should be protected by shading it from direct sunlight.
Do not allow water to be sprayed onto the transmitter lenses. During wet conditions, fit a protective shroud over the beacon.
Power supply to Trackside beacon
The beacon operates from a 12v DC supply. A sealed lead-acid battery with a minimum rating of 2.5 Amp/hour is recommended. This
provides about 15 hours of operation.
Connect the Brown wire to the positive (+) terminal of the battery, and the Blue wire to the negative(-) terminal.
The condition of the battery is indicated by the colour of the LED indicator on the front panel of the unit:
•
Green:

Red:
