2 INT69 DIAGNOSE The widely known protective system INT69 and INT69 TM present on all Frascold compressors is now boosted by the version INT69 Diagnose and INT69 TM Diagnose, which incorporates innovative diagnostic functions. How it communicates The IN69 Diagnose system allows, via a simple USB connection, to download all the operating parameters of the compressor for the last 7 days and for the last 20 critical events. With an additional device it can also communicate with Modbus system technology in order to have remote monitoring Main benefits This system, in addition to analyzing the operating conditions of any given moment, allows to run a retro-active survey. Therefore, in the case of abnormal conditions, it directly aims for the heart of the problem that needs to be solved, instead of proceeding by trial and error. Additional functions The INT69 Diagnose system also integrates protective and innovative functions, such as: function to recognize adjustments attempts (for example, an exclusion attempt) short-cycling function (recognizes an excessive number of start-ups and stops the compressor) stop function in case of a locked rotor (for example, liquid compression) function to monitor the lubrication (in combination with the INT250 (by Kriwan) oil pressure switch, visualized via LED, for the TM version only) Easy fit: The system INT69 Diagnose, directly installed on board of the compressor, allows its universal application, even on pre-installed plants, with easy connections to the electrical panel. Dual voltage 115/230 V, 50/60 Hz Easy use The management software and the practical use and maintenance manual allow an easy and straightforward use. Frascold organizes training courses when necessary. To connect to the PC, a USB cable is needed, available on request.

3 INT69 Diagnose INT69 TM Diagnose Extends the life of refrigeration systems Improves compressor protection Quickly identifies the causes of malfunctions Reduces management and maintenance costs Can be consulted with a USB connection to PC Can be consulted by means of Modbus system technology (remote monitoring) It is also applicable on already installed and operating compressors INT69 Diagnose and INT69 TM Diagnose are the intellectual property and registered trademarks of KRIWAN Industrie-Elektronik GmbH

4 General Characteristics Function Intervention Action Visualization Objective and benefits Programmed control of number of start-ups Stops the compressor for 5 minutes in case of more than 2 starts in 30 seconds Extension of the operating life. Less stress to motor Monitor the presence of the electrical power supply phases Control of the running time of each start-up Run detection Recognition of attempted adjustments Stops the compressor, recognizing the attempted adjustment operational statistics For remote monitoring with Modbus technology system Analysis to optimize the system To verify that the compressor is in functioning or not knowledge of the causes of the faults Data save (last 7 days) Analysis to optimize the system. Better knowledge of the causes of the faults Monitor the motor temperature and Monitor the discharge temperature Control of motor temperature based on the threshold value and on the rate of increase) Control of discharge temperature based on the threshold value Control of alarm temperature (distinction between the motor and discharge) Stops the compressor, recognizing that the threshold has been exceeded orthat the rotor is locked Stops the compressor in combination with the discharge temperature sensor Stops the compressor knowledge of the causes of the faults. Less damage from mechanical stress in case of a locked rotor knowledge of the causes of the faults knowledge of the causes of the faults.less damage from mechanical stress in case of a locked rotor Memorization of the last 20 alarms Better knowledge of the causes of the faults. Analysis to optimize the system Monitor the lubrication (TM Mod. only) Oil pressure control in pump inlet and outlet Safety with manual restart Stops the compressor in combination with the INT250 (by Kriwan) oil pressure switch Restarts the compressor, provided the cause of the fault is no longer present Extension of the operating life of the compressor. Connections to electrical panel simplified (all the controls on the pump are connected to the module) Extension of the operating life of the compressor. Signal of operating condition (TM Mod. only) Via LED directly on device Easy use Operation extension Operation with inverter (25-70Hz) Easy Fit Placement Inside the box Easy Fit Reset Manual for pump functionalities, automatic for all the rest Easy Use Power supply Only one device for: 115/230V 50/60Hz Easy fit Brand on the market Protective function Diagnostic function

5 the software Control Overview In the opening screen Overview, all the devices connected to the PC can be viewed and the user chooses which one he wishes to analyze. There are 3 menus at the bottom: Compressor data contains the information about the compressor. Maintenance contains the notes regarding maintenance, and in the Archive menu, the user can view all the data saved previously. Operating time This screen displays the hours of operation of the compressor and a graph in which the user can view the percentage of time during which the compressor has been operative and during which it has been off. Compressor running time This screen-shot displays an analytical graph: the light-blue columns indicate the running time after a start-up, allowing to understand if the compressor has remained on only for a few minutes or for a more prolonged time. Switching cycles of the system In this screen-shot instead, one can view the number of starts per day over the last 7 days, thanks to the yellow columns, and the number of maximum startups in an hour, thanks to the red columns.
