For information on how to use the activity meter system in the farm management system, please consult the DelPro / ALPRO user manuals. The DeLaval activity meter system is a wireless, electronic heat detection system for cows and heifers approaching heat. The purpose of the DeLaval activity meter system is to alert the farmer when an animal becomes more active than normal, which usually indicates that the animal is in heat. The system uses also Low activity to alert the farmer when animals become less active than normal, indicating that the animal may have a health issue and needs to be checked. © DeLaval 2014. 2014-02-17, Version 4 9 (44) 87224201 DeLaval activity meter system General description 2 Parts of the DeLaval activity meter system 239669 Fig. 1: Parts of the DeLaval activity meter system DeLaval activity meter AM2 DeLaval activity receiver AR2 Antenna System controller with ALPRO WE © DeLaval 2014. 2014-02-17, Version 4 Transformer PC with DelPro software (or ALPRO Windows software) Router (optional) 10 (44) 87224201 DeLaval activity meter system General description 3 Functional overview n The activity meter AM2 contains a sensor which detects movements. The movements are aggregated into an activity level. The activity level data is continuously collected and transmitted to the activity receiver every hour. Every data transmission contains activity data covering the latest 24-hour period. n The activity receiver AR2 is the link between the activity meters and the ALPRO WE on the system controller, where data from the activity meter is processed. The activity receiver receives the radio signal from the activity meter via the antenna.The received message is checked for validity, and then it is transmitted over the ALCOM bus to the system controller. n The system controller with ALPRO WE software collects and stores all incoming activity data. Its main task, for heat detection purposes, is to process the activity data into high activity alarms. n A PC running DelPro / ALPRO Windows software reads and stores the processed activity information from the system controller and presents it in graphs and reports. 239670 4 Features of the DeLaval activity meter AM2 Fig. 2: DeLaval activity meter AM2 © DeLaval 2014. 2014-02-17, Version 4 n To distinguish the AM2 from the previous generation activity meters, the cover has a blue/grey colour combination. See Fig. 2. n Activity sensor: A digital accelerometer provides accurate motion detection. The allelectronic implementation improves reliability and quality of the product. n RFID-activated start up: The DeLaval activity meter AM2 will be activated (enter ON mode) automatically when exposed to a 131/134 kHz RFID reader signal. Either as the cow passes an RFID reader, or manually by bringing the AM2 close to an RFID reader. n Automatic shut-off: The AM2 automatically shuts off after 48 hours of inactivity (all zero activity for 48 hours). When an AM2 is temporarily not used, simply put it on the shelf. 11 (44) 87224201 DeLaval activity meter system General description n RF communication protocol: A high speed, multi-channel RF communication protocol is used to improve system capacity (maximum number of cows with AM2) and to improve immunity to RF noise and interference. n Internal lithium battery: Battery life time is up to 10 years. 5 Features of the DeLaval activity receiver AR2 241095 n Identification: To visually distinguish the AR2 (see Fig. 3) from the previous generation activity receiver, the front label has a DeLaval logo. n RF communication protocol: The AR2 supports the AM2 radio protocol. n RF range: The AM2 to AR2 communication range is typically 200 m line of sight, outdoors. n Remote software upgrade: software upgrade of the AR2 is supported over the ALCOM bus in DelPro as well as ALPRO systems. Fig. 3: DeLaval activity receiver AR2 © DeLaval 2014. 2014-02-17, Version 4 12 (44) 87224201 DeLaval activity meter system General description 6 Co-existence and compatibility with the previous generation activity meter system AM2 and the previous generation activity meters can be mixed at the farm, considering a few prerequisites: n The activity meter AM2 always requires an AR2 receiver with antenna. When introducing AM2 meters, one or more AR2 receivers must be installed. The AR2 is preferably mounted close to existing activity receivers, to share the existing ALCOM bus and power supply. n AR2 ALCOM node address ALCOM node addresses for AR2 must be sequential and starting higher than existing receivers. This will enable batch SW upgrade of the AR2. n A 131/134 kHz RFID reader (any DeLaval ID reader) is required to start up the AM2. If there is no RFID reader available, a Handheld ID reader could be used for manual start up. n Radio frequency channels: The AM2 and AR2 use different, multiple radio channels. Thereby AM2 will co-exist with previous generation activity meters without radio interference. n AR2 compatibility on the ALCOM bus: The AR2 is by default (from the factory) configured in an ALCOM backwards-compatible mode. Activity messages received from AM2 meters will be converted to a legacy message format. The 24-bit unique AM2 serial number is truncated to a 16-bit address (0-65535). n ALPRO WE/DelPro /ALPRO Windows compatibility: In backwards-compatible mode, the DelPro and ALPRO system will process activity data from the AM2 in the same way as the previous generation system. The management system will not be aware of the activity meter version. Note! The AR2 does not support previous generation activity meters. Note! The AR2 does not support download of previous RFI SW versions. Note! A magnet cannot be used for manual start up. Note! The Tag tester cannot be used with the AM2. © DeLaval 2014. 2014-02-17, Version 4 13 (44) 87224201 DeLaval activity meter system General description 7 Environmental specification DeLaval activity receiver AR2 Ideal environment Outdoors, under roof Operating temperature -25 °C to +55 °C Storage temperature -40 °C to +70 °C Humidity 10-100% RH DeLaval activity meter AM2 Ideal environment Outdoors, on animal Operating temperature -25 to +55 °C Storage temperature -40 to +70 °C Recommended storage temperature +5 to +35 °C Humidity 10-100% RH Note!

Farm management software start up. 2. System controller with ALPRO WE start up. 3. Introduction of cows to the system. 4. Checking breeding parameters. 5. Breeding data introduced to the system. The specific DeLaval activity meter system start up includes: n To configure the activity receiver in ALPRO/ DelPro. n To activate the activity meters and mount them on the cows. n To enter the activity meter numbers to the correct cows in the farm management system. It is recommended that the activity meter stays permanently mounted on the cow. 2 DeLaval activity meter AM2 start up Activity meter AM2 is in status OFF when delivered. The activity meter AM2 will be activated (enter ON mode) when exposed to a 131/134 kHz RFID reader signal, for example an ID portal at the milking parlour, a VMS, sort gate or a feeding station with ID reader. Note! The AM2 does not respond to an RFID reader signal, and will not generate an "unknown" transponder in the herd management system. © DeLaval 2014. 2014-02-17, Version 4 36 (44) 87224201 DeLaval activity meter system Start up Depending on the availability of RFID-readers on the farm, there are two different methods to start up the activity meter: manual or automatic activation. 2.1 Manual activation For heifers and non-milking animals that will not pass by an RFID reader regularly, the AM2 has to be activated manually before mounting onto the animal. If there is no RFID reader installed on the farm, a Handheld reader (HHR) can be used for activation. Activation of the AM2 1. Bring the AM2 close to an RFID reader. The activation distance is comparable to ID transponder reading range, approximately 30-40 cm maximum. 2. Keep the AM2 within reading range for about 5 seconds, while slowly turning the activity meter around. This is to allow successfull activation for the activity meters. The RFID sensor of the AM2 is direction sensitive just like any RFID transponder. There are no restrictions on how many AM2s that can be started within a short time. A random delay at start up will ensure that any number of AM2 does not transmit the hourly activity report at the same time. It means that a full box of 40 AM2 activity meters can all be activated at the same time by bringing the whole box trough an RFID reader. The box should be shaken to ensure a successful activitation. As soon as the AM2s are activated but no animal number is yet assigned, these tags will be listed under "Unknown tags" in the herd management system. It is recommended to do a print out and use it to write down the cow numbers while mounting the neckbands with the activity meters on the animals. See Ä Chapter 3 "Matching activity meter ID number to cow number" on page 38. Note! If the AM2 is not moved (not installed) within 48 hours of activation, it will shut off automatically and will have to be activated once again before installation. © DeLaval 2014. 2014-02-17, Version 4 37 (44) 87224201 DeLaval activity meter system Start up 2.2 Automatic activation This method is convenient for all cows that will pass an RFID reader regularly, for example an ID portal at the milking parlour, a VMS, sort gate or a feeding station with ID reader. AM2 activity meters are installed on neckbands and mounted onto cows before activation. As the cow then passes an RFID reader, the AM2 will start automatically. It is recommended to do a print out and use it to write down the cow numbers while mounting the neckbands on the animals. See Ä Chapter 3 "Matching activity meter ID number to cow number" on page 38. 3 Matching activity meter ID number to cow number The activity meter serial number is engraved on the grey front part of the AM2. The format is 123 XY 45678. The activity meter ID number used in the system is the 5 digit number (45678) to the right of the two letter date code (XY). When mounting the activity meters onto the cows the activity meter ID number must be associated with the correct cow. Create a list with the cow numbers and write down the assigned activity meter IDs. After installation enter the list of activity meter ID numbers in the farm management system. In DelPro software: 1. Use batch edit "Animal general" to add the activity meters to multiple animals, or open the "Animal card" for a specific cow and go to the "General" tab. 2. Enter the activity meter number in the "Activity tag number" field. In ALPRO Windows: 1. Use "Batch entry" and select "Change Activity Tag" . 2. Enter the activity meter number in the "Activity tag no" field. © DeLaval 2014. 2014-02-17, Version 4 38 (44) 87224201 DeLaval activity meter system Start up 4 Confirmation of AM2 start up The activity meter will have status On in the "Activity tag status" field in the "Animal Card è General" after the first activity data message has been received by the herd management system. An activity meter that has been started but not been correctly matched, or not yet assigned, to a cow will show up as an "Unknown activity meter". For more information see the section Ä Chapter 1 "General" on page 40. 5 Operation Normal operation of the activity meters involves moving activity meters from one cow to another, replacing faulty or lost activity meters. The procedures are the same as during system start up. © DeLaval 2014. 2014-02-17, Version 4 39 (44) 87224201 DeLaval activity meter system Troubleshooting Troubleshooting DeLaval activity meter system DeLaval activity meter AM2 DeLaval activity receiver AR2 1 General No. Symptom Cause Action Cow with activity meter does The activity meter number has not show any activity data in been wrongly entered. filters, reports or graphs in The cow is out of the range of the HM software. the antenna.
