Connection Instructions – Solenoid Starting Module
These instructions apply to the solenoid option where solenoids are at the start of the racing track
and infrared beams at the end.
Please refer to the installation diagram named “Race Timer – Solenoid Starting.” The number on the
diagram refer to the numbered points below.
Follow these steps for before operating the units and the PC software when the optional starting
module and associated solenoids are deployed.
1.
Mount both solenoids so that they launch the race as required (M4 screws are provided).
For example when launching CO2 racing cars the following considerations are vital:
a.
The solenoid plunger must be directly against or fixed to the CO2 firing pin. If not
then the gap will significantly reduce the force applied to the pin.
b.
The impact of the pin and the CO2 cylinder should be around 3mm (1/8”) from the
end of the 12mm (1/2”) travel of the solenoid. This will maximise the impact and
puncture force. The firing pin should be sharp and made of hardened steel.
Warnings:
1.
Solenoid damage will occur if the mounting screws penetrate the solenoid body
beyond the internal plastic shield.
2.
When triggered, a lot of power is discharged into a solenoid which closes with
considerable force. Ensure appropriate safety precautions are employed in
mounting and operating the solenoids.
2.
Plug the solenoid for each lane into the starting module matching the red and black plugs to
the correct lanes.
3.
Connect 3.5mm leads from the starting module control inputs to the associated outputs on
the main controller module for both lanes 1 and 2. Note that any leads should be physically
secured (e.g. taped down) in order to keep them clear of any moving components/vehicles
and secure them against trip hazards.
4.
Connect 3.5mm leads from the main controller module inputs to the two trigger switches for
both lanes 1 and 2. Note that the lead can go either way around.
5.
Plug in the power pack to the mains and the power input of the starting module. Make sure
that the power LED illuminates.
6.
Mount two (2) IR receiver modules on either side at the finish line, clear of the end of the
track so that the IR beam will not be blocked. Make sure that the IR beam module entrance
holes point across the track, so there is no interruption of the line-of-sight path of the beam.
Double sided tape or glue can be used to fix the IR receiver and transmitter modules in their
correct locations. Note that the receiver and transmitter modules can be placed either way
up so that IR light beam is aligned and the connections are conveniently placed to ensure
the signal lead is kept clear of the moving car. Finally ensure that the IR beam height is such
that it will be decisively interrupted by the moving car (e.g. a beam height of 20-30mm
above the base of the track for CO
2
racing cars).
7.
Mount a single finish IR dual transmitter between tracks and point directly to each of the IR
receivers from the IR beam holes on each side.
8.
Connect 3.5mm leads from the IR receiver modules to the correct receiver inputs on the
main controller unit for both lanes 1 and 2.
