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.
