Messages, Milking Codes and Alerts Milking codes, and messages are a means of communication between milkers and the computer. Messages are sent by milkers from a milk meter to the computer. Messages are explained on page 12. Milking codes are sent from the computer to a milk meter. Codes warn milkers of cows that need special attention. Milking codes are explained below. Alerts are calculated from real-time data. Alerts are explained on the following page.
Codes 5, and 8 – Afi-lite Alerts Of the eight “milking codes” (1-8), most codes can be used to determine situations as determined by the herd manager. Two codes 5 and 8, are predetermined in AfiFarm as alerts in specific situations. Code 5 designates a dry cow. If a dry cow is identified at a milking point, this code is triggered. This alert helps prevent milkers from attaching a cluster to a dry cow. This alert is automatically removed upon calving, when a calving date is entered.

Messages Messages can be sent from an Af-lite milk meter to the computer. A message can be sent to the computer database, to make a notation on a cow, and is seen at the computer, when reviewing reports. One message per cow can be sent, per milking. A message is first entered into the milk meter. Then, when the exit gate is opened, the message is loaded into the computer, together with milk data of the cow. For example: A milker may note that cow 1299 is limping.
Example A: To send a message to the computer that cow 1299 is limping (if the number 34 is designated as the message for “limping cow”): At the milk meter where cow 1299 is identified, press: and then press . The message is entered into the milk meter. When the exit gate is opened, the message is loaded into the computer and assigned to cow 1299. After the message is entered, the milk meter display returns to its previous reading. Example B: A message can be sent to assign a code to a cow.

Chapter 3: Setting Afi-lite Parameters Parameters are variables that must be given a value, for the execution of a program. Some parameters in the Afi-lite software control cluster removal functions. Another parameter defines the milk meter identification number of each milk meter. This chapter describes how to set cluster removal and milk meter ID parameters. Milk Meter Identification Parameter Each milk meter must be assigned an identification number. ID numbers are assigned during installation.
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 Amount of milk 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.
Changing Values of Cluster Removal Parameters To change the values of cluster removal time spans, proceed as follows for each parameter, at each milk meter: 1. Enter programming mode: Press , and simultaneously. 2. 3. Navigate to respective “family” of parameters. To reach parameters and , press simultaneously. , , & appears for a few seconds. Then (1st parameter in the “family”) appears. To reach parameters , press & simultaneously. appears for a few seconds.

Chapter 3: Cleaning Routine This chapter describes general cleaning guidelines, warnings, and recommendations. Warnings: • Always comply strictly with the instructions of the chemical manufacturers! Failure to comply with the instructions can cause injury and damage to equipment. • Use gloves and protective goggles when working with chemical detergents. • Prevent any contact with active detergents and acids in the same container.
General Instructions The cleaning cycle of the AfiFlo milk meter body is executed in the same manner as any standard milking system cleaning cycle. The following conditions must be fulfilled in every cleaning cycle. • The vacuum pump operates throughout the cleaning cycle. A temporary halt in vacuum while the sink is being filled can cause milk and cleaning fluid to penetrate outwardly into the grooves of the gaskets. • The milk meters are in cleaning mode.
Cleaning Cycle There are various cleaning systems and procedures in use in milking parlors. Nevertheless, the following rules must be followed for all the procedures and detergents in use. Detergent Wash 1. Initial cleaning in an open circuit, to rinse out residual milk: Use luke-warm water that is emptied in the drain, until the water becomes clear.
Acid Wash Do this acid wash once a week, or more frequently, where necessary. This acid wash is not in place of the daily cleaning routine. (There are some cleaning solutions available that remove both milk residues and hard water salts.) 1. Rinse the detergent solution out of the system with cold water. 2. Circulating with phosphoric and/or sulfuric acid.
Chapter 4: Milk Meter Body and Fat Sampler This chapter contains information about: • The basic structure and components of the AfiFlo milk meter body. • Silicone and rubber component replacement. • The fat sampler.

The AfiFo milk meter body is a plastic container made up of three main parts: • The Upper Cover and Inlet Port: Milk enters the main chamber through the inlet port. • The Main Chamber: Milk fills the mid section while the valve is closed (in upper position). • The Lower Cover and Outlet Port. When the solenoid is energized, the valve opens and releases the milk. The milk flows through the lower part and outlet port to the milk line. Within the AfiFlo milk meter body are: • Three electrodes.

The Fat Sampler International dairy authorities, as well as most local dairy authorities, require the sampling of milk during the milking process. Mounting a fat sampler enables the dairy to comply with these regulations. Mounting the Fat Sampler The fat sampler is mounted between the outlet port and the elbow joint to the milk line. NOTE: During normal milking, when not sampling, a sampler replacement tube fills the gap reserved for the fat sampler.
Chapter 6: Troubleshooting The Afi-lite milk meter is equipped with alerts to advise milkers of problematic situations. There are two kinds of alerts: • Premature cluster removal alerts. • Operational fault alerts (error alerts). Premature Cluster Removal Alert A cluster can become detached before the end of milking. Premature cluster removal is indicated by a flashing display of milk yield.
Output #2: Solenoid that controls removal device Output #3: Solenoid that controls vacuum shut-off to cluster Output #7: Solenoid that controls front pulsator Output #8: Solenoid that controls rear pulsator Error Alert This alert indicates that the milk valve has been in the open position for an abnormally long time, and may be stuck in that position. Error Alert This alert indicates a communication problem. Call the dealer for service. More Troubleshooting Your dealer will be pleased to assist you.
