Tidtagnings systemet måste sättas på enligt FIS-reglementet.
Klockorna måste klara alla krav FIS ställer och måste därför vara homologiserade. ALGE-klockor
som är homologiserade av FIS:
For FIS events, Wireless Time-of-Day Data transmission by radio (11) is permitted for use as the back-up System B timing system only if the System A timing wires (1) are connected to one starting gate contact and a homologated Time-of-Day Timer is connected to the other starting gate contact (2).
Startclock:
Voice Communication:
Timing Cables:
< Cells at
intermediate time:
Cells at the
finish line [(3) und (4)]:
There are two categories of cells:
2. Transmitter-Receiver Type RLS1nd or RLS1cd:
The cells must be connected to the timing devices by wire. No radio transmission is allowed.
In all cases, max. vertical separation of the beams cells may not exceed 20 cm. (+/- 8")
Starting Gate:
Minimum of 2 electronically isolated contacts activated by 1 wand. Timing wires (1) & (2) must be connected to separate start gate contacts(e.g. ALGE STScM2S or STS3Q).. The wand must be installed so that starting is impossible without it opening.
Must be connected on the starting gate for synchronisation, if used.
.
Timing impulse and voice communication functions must be separated on different wire pairs if manufacturer's specifications dictate. For ALGE devices you can use for voice communication and timing impulse the same wire. If radios are used for voice communication, a dedicated channel must be used.
Make sure that cables cannot be torn out at the start by a competitor, or by any other person next to the starting area.
Locate Cells carefully in co-ordination with the Technical Delegate and/or the Race Jury. To avoid the cells being triggered by anyone other than the competitors, it is recommended that the person responsible for that intermediate timing point use a push-button to arm the photo cells only when a competitor crosses the line.
It is recommended to level the finish area. Locate Cells carefully in co-ordination with the Technical Delegate and/or the Race Jury.
1. Reflector Type RLS1c or RLS1n:
Both transmitter and receiver are on the same side and use a reflector on the other side.
Transmitters can either be on opposite sides or on the same side, depending on the manufacturer's specifications. For ALGE photocells we recommend to use both transmitters on one side, and the receivers on the other side.
System B (6):
Start line (2) and finish cell (4) must be connected.
System B (12):
For FIS events only, the start line may be connected through radio transmission and cell (4) for finish is connected by wire to System B
Manual hand timing:
In all cases hand timing is compulsory.
Stopwatches, with or without printers, should be synchronised to the time of day and used at the start and at the finish.
A complete list of hand times recorded at the start and the finish must be given to the chief of timing at the end of each run, or immediately upon request.
Synchronisation: All elements of the timing installation, must be installed and be in good working order at least one hour before the beginning of the competition. Timers should be turned on 30 minutes before synchronisation to allow the quartz time bases to stabilise.
Synchronisation must be done 30 minutes prior to the start of each run and must not be re-synchronised while the run is in progress. The synchronisation impulse for all timers must come from the start gate. One minute after synchronisation is done, a new impulse must be sent by the start gate to check synchronisation accuracy on Systems A and B.
Should any important discrepancies be observed when this check is performed, synchronisation should be redone and checked again prior to the start of the run.
Manual stopwatch synchronisation must be done before or together with the synchronisation of the whole system.
Reminders:
In case of timing problems, the chief of timing must inform members of the jury or the finish referee immediately.
Starter and official timekeeper should agree upon using specific terms and commands during communication. This dialogue should be short and precise, as well as systematically repeated for each competitor. In all cases it is recommended that the starter always informs the timekeeper(s) at the finish as soon at a competitor leaves the start.
At the end of each run or competition, before sending out the results, times and ranking from the timing systems and the computer results system must be compared and cross checked for accuracy
Notes:
At the end of the competition, it is compulsory to give the Technical Delegate the enclosed "Timing Report Form", as well as the printed tapes from the System A, System B and all hand timing records.
