The Stall Lag Facility.

Parlours in which the stalls are unusually close together or those that have metal work which
tends to distort the scanning field, may occasionally experience two different tags being read at
the same stall. The combination of the parlour structure and cows that swing their heads about
can bring an ear tag into the field of an adjacent stall where it will be read.
To overcome this problem the Stall Lag facility double checks the location of each tag. The 'lag'
period is determined by the number of stalls you ask the system to check before feeding. So, if
the lag is set to 2, stalls 1, 2 and 3 will be checked and confirmed as being consistent before
stall 1 is fed. In other words, a lag of 2 reads and confirms 2 stalls ahead of the current stall.
With this setting, when the current stall reaches 7, stalls 8 and 9 will be checked before the cow
in stall 7 is fed.
To set the Stall Lag:
Press Reset.
Run subroutine 306 which is the Stall Lag subroutine number. The display will show
'Lag' in the Cow Number window and the existing lag value (if there is one) in
the Milk Yield window.
Press the Change key to alter the value. Either one or two underscores will appear in
the Milk Yield window.
Key the new lag value. Generally 2 or 3 is sufficient and you may not enter a figure
greater than the total stalls in a side. No need to enter leading zeros.
Press Enter and the value is stored.
The Stall Lag facility is 'invisible' inasmuch as it will not change the way you milk your cows or
be perceptible during the scanning process. However, it will delay feeding slightly- the higher
the lag value the greater the delay.

Be aware that the Stall Lag facility is not a
'cure' for parlours which are inherently
unsuitable for scanning Auto-ID.
The system MUST function properly before
applying Stall Lag as a 'fine tuning' process.
