1 New ADAP-KOOL AK-CT 200 One Hardware for over 300 tray variants Refrigeration and A/C Controls Division Date 1

2 Fully Integrated gear tray and case controller Today s power tray solution Standard electromechanical components and electrical wiring New ADAP-KOOL AK-CT 200 Integrated power components Current measurements Zero-crossing technology Pluggable spring loaded wire connectors Create variants by different selection of electrical components and wiring: Large number of customized trays Different electromechanical fuse sizes Many different blueprints Different power trays for 1 and 3 phase Create variants by software configuration: 1 version with software configuration of relays and application soft wiring Configurable fuse size (0->16 Amp) One common label for all display cases Power management from 10 Watt to 10 KW Danfoss Food Retail February

3 Existing Norpe different variants Service switch Case Controller Wiring diagram / documentation 300 different blue prints Internal Wirings Fuses Contactors Connectors for external wires Danfoss Food Retail February

4 Reduced complexity with new Integrated Controller Tray Reduced complexity Fewer variants Lower risk of wiring mistakes Quick configuration Improved service features Easy check of I/O s Easy food type setup Improved monitoring Easier remote analysis Extended information for data analysis Fast reaction time from alarm to service First time fix Reliable Robust against electromagnetic interference (EMC) Zero crossing relays Static cooling Easy controller service One fits all Danfoss Food Retail February

5 AK-CT 200 providing benefits throughout the value chain OEM production In store commissioning Onsite service Remote monitoring OEM production In store commissioning Onsite service Remote monitoring More than 300 variants with one hardware Simplified handling of gear trays Less wiring mistakes Easy I/O check Time saving with Quick Configuration Communication status for fast fault finding Easy change of food type Easy I/O check Reduced time for trouble shooting Remote current monitoring Remote fuse information and reset Door openings Root cause alarms First time fix Danfoss Food Retail February

6 Controller key for late dedication Control function can be defined at the end of production line. Only one tray version for more than 300 different cabinets. AK-CT201 Enable controller tray to be used with 3 rd party controller AK-CT 450 Enable controller to control display case with TXV AK-CT550 Enable controller to control display cases with AKV Common features for all 3 versions Manual override of light via pushbutton (DI) Stop of fans while blinds down Fan ECO - Reduced speed while blinds down High power control of more than 300 different display cases Danfoss Food Retail February

8 EVR Danfoss Food Retail February

9 AKV Danfoss Food Retail February

10 Application selection from param. o61 Danfoss Food Retail February

11 Zero cross relay control vs. traditional contactors Cut In Sparks Cut Out Traditional contactor Mechanical life time? No control of Cut in or Cut out of loads -> high tear and weariness High power PCB relay with Danfoss Zero crossing technology High mechanical lifetime Long lifetime on contacts due to limited (no) spark at cut in or cut out of loads Voltage = 0 Amp = 0 Danfoss Food Retail February

12 Current measurement & alarms MAX MIN alarm! Danfoss Food Retail February

13 Programming can be done in different ways Via Modbus with own production and test software Via Danfoss AK-SM 720 and AK- ST 500 Via OEM programming key + PC with USB connection and Microsoft Excel Danfoss Food Retail February

15 ID-key copy - Parameters are stored in the ID-key + AK-CT 200A. - AK-CT will work for 2 weeks without a ID-key - network address (o03) is also copied Danfoss Food Retail February

16 How do I reset a software fuse? Fuse alarms can be seen in AKA 164 display E41 = Fuse alarm on DO1 E42 = Fuse alarm on DO2 E48 = Fuse alarm on DO8 Flashing red Fuse LED indicate fuse alarm on one or more of the relays DO1 -> DO8 Fuses can be reset in 3 different ways: 1. Power Off and On via circuit breaker will restart the controller and reset fuses 2. Fuse can be reset in Service menu for output status when FuS is shown for do1 -> do8 by setting output to on 3. Fuse can be reset in configuration menu by parameter L21 to L28 set to on from AKA display or remote by setting to 1 Danfoss Food Retail February

17 New controller tray accessories Extra connectors for multi wires If more than 3 cable connectors are needed Optional AKA 164 display Can be mounted in controller tray or in display case Controller key for late dedication AK-CT 201, CT 450, CT550 Controller functions and copy of settings Danfoss Food Retail February

18 Accessories Prepared for optional connector Space for optional display Danfoss Food Retail February

19 System Manager compatibility -SM 720 ver.2.73 OK -SM350 ver.1.70 OK, but no template yet! -SM800 ver OK. -AKA 24x (LON) partly: missing param. with AK-CT550A: Danfoss Food Retail February

20 Other info - Appliance shut-down function (=external main switch, but no stand by alarm) - Modbus communication status, 0/100% = everything ok, (U45) - Pe & AKV connector identical, careful when replacing controller! - Not used fuses; 16A by default, set to 0A - EEC coil not supported - HACCP approved, CE & other electrical approvals available - Measurement of insulation 500V. Loads must be manually wired (can t push manually contactors like normally) - No Danbuss option - EKA 183A copy key support coming from next version (sw. 1.32) - Integrated 24h real time clock - ECO function for evap. fans (cut fan speed when night blind down) - 2-light relays (spot lights) - Controller & AKV powered from L1 (1-phase) V output for valve OD (AO1) Danfoss Food Retail February

21 Room application - Need 2,5 mm 2 cabling, also AKV. (Check with local authorities!) - When door function is open it signals that the door is open, usually motion detectors are NO (DI7), needs extra relay - Residual-current circuit breaker (30mA) needed for rooms (personal safety, rail/drip tray heat) - Only for 1-phase evaporator fan Danfoss Food Retail February

22 Instruct electricians to check for missing neutral! - Normally this is not part of electrical installation inspection! Danfoss Food Retail February
