Operation in Cleaning Mode

An automatic delay schedule prevents excessive load on the power supply.
During Cleaning Mode, valves are pulled up and the milk chamber is emptied.
The automatic delay schedule desynchronizes the pulling up of the valves
thereby preventing excessive load on the power supply.
The schedule creates a delay of 100 msec between stalls and is set according to
milking point numbers. Every seventh milking point has the same delay time.
In a 12 station parlor, this results in the following operation pattern:
•
The valves of stalls 1 and 7 are pulled up first.
•
The valves of stalls 2 and 8 are pulled up after a 100 msec delay.
•
The valves of stalls 3 and 9 are pulled up after a 200 msec delay.
•
Etc.
The delay is counted from the time the cleaning mode is activated. Synchronize
the parlor in cleaning mode by setting all milk meters in cleaning mode and
switching the power to the parlor off and on again.
