Automatic Cluster Removal (ACR) Parameters

The Afi-lite milk meter detects when the milk flow rate from the cow has slowed

enough to stop milking, then it removes the cluster.

ACR Parameters

Four parameters are involved in determining when the cluster is removed , ,

and .

determines the minimum amount of time the cluster is attached. This

parameter is also referred to as the “first delay”. The value of is

multiplied by 10. The resulting value is the minimum number of seconds the

cluster is attached. If the value is 18, then 180 seconds (three minutes) is the

minimum attachment time. If you want to

reduce the minimum attachment time to two and

a half minutes (150 seconds), change the value to

15.

Parameter helps prevent premature cluster

removals from cows with a slower milk let-

down.

determines the milk flow rate at which milking

will stop. When the flow rate of milk from the

cow decreases, the milk meter body is emptied at

greater intervals. When the milk meter body is

not emptied within the time specified in , the cluster is removed.

Milk flow rate is calculated as follows:

(Near the end of milking, 200 – 220 grams (0.2 kg = 0.44 lb [6.5 oz.]) of milk are released

each time the milk valve is opened. [The amount is measured.] 210 grams (6.7 oz) is used

in the calculations below.)

In this example,

= 30 seconds.

Therefore, if has a value of 30,

milking is stopped when the milk flow

rate drops to 0.42 kilograms (13.2 oz.) per

minute.

controls the delay between the vacuum

shut-off and cluster removal (usually

one second).

is the maximum cluster-on time, in

units of ½ minutes. (For example, a value of 14 is a maximum cluster-on time of

7 minutes. The time value of must be greater than the time value of . )
