THEORY OF OPERATION

The 3220 Series Timers are completely self contained race timing systems made with CMOS circuit components to provide a highly accurate timing solution. The system contains an internal quartz crystal clock for time accuracy and display of race results to one thousandth of a second.

Power is supplied to the timer console and track sensor components of the 3220 by the 12VDC automotive battery connected to the RED and BLACK alligator clips, cigarette lighter adapter, or an AC adapter. An absolute minimum of 11.0VDC is required for reliable operation of the system. Under normal conditions, charged batteries will operate for days without a recharge.

The Beam Emitters and Track Sensors operate on invisible (to the unaided human eye) Infra Red light. The coded light frequencies are constantly received by the Track Sensors until a car interrupts reception (‘breaks’ the beam).

The IR Beam Emitter to Track Sensor transmission operates on Line-of-Sight principles. This makes alignment of these units critical. Tips are provided to aid alignment on surfaces that are other than ideal. These units will operate over a wide range of conditions but should not be operated beyond the specification parameters (less than 4 ft or more than 50 ft).

Once the system is properly set up and aligned, the timer console will ‘monitor’ the track sensors each time a run is made.
