Home lem_current_page : FAQs TECHNICAL FAQS GENERAL WHICH PARAMETERS MUST BE CONSIDERED WHEN CHOOSING A TRANSDUCER? HOW IS “PRIMARY NOMINAL” RMS CURRENT OR VOLTAGE DETERMINED? WHAT DOES “MEASURING RANGE” IMPLY? WHAT IS THE FUNCTION OF THE MEASURING, BURDEN OR LOAD RESISTOR (RM, RB)? WHAT ARE THE LIMITS OF MEASURING RESISTOR (RM, RB)? WHAT IS THE TRANSFORMATION RATIO? WHAT IS THE CURRENT CONSUMPTION IC ? HOW SHOULD THE POWER SUPPLY FOR A TRANSDUCER BE DIMENSIONED? HOW IS THE RESPONSE TIME (TR) DEFINED? HOW IS THE REACTION TIME (TRA) DEFINED? WHAT DOES “DI/DT ACCURATELY FOLLOWED” MEAN? HOW IS THE FREQUENCY BANDWIDTH BW DEFINED? WHY ARE TRANSDUCERS SUBJECT TO CORE LOSSES? WHAT IS THE CURRENT DERATING VERSUS FREQUENCY? HOW ARE SENSITIVITY AND LINEARITY MEASURED? WHAT ARE THE ADVANTAGES OF TRANSDUCERS USING AN ASIC? HOW DO TRANSDUCERS WITH A UNIPOLAR POWER SUPPLY WORK? HOW CAN MAGNETIZATION OF THE CURRENT TRANSDUCER BE AVOIDED? CAN A TRANSDUCER BE DEMAGNETIZED? WHAT ARE CLEARANCE AND CREEPAGE DISTANCES? WHAT ARE PARTIAL DISCHARGE PHENOMENONA EXPLAINED? WI-LEM: MESH NETWORK - RF COMMUNICATION AUTOMATIC DETECTION OF ANY NEW DEVICE IN THE MESH NETWORK INFORMATION ON THE MESH NETWORK ROBUSTNESS TROUBLESHOOTING: THE MESH NETWORK IS UNSTABLE AND DOES NOT REPORT MORE THAN 10 DEVICES VISUAL CHECK OF A DEVICE’S ACTIVITY STATUS LONG RECOVERY TIME FOR THE TOTAL MESH NETWORK IN CASE OF MESH GATE SHUTDOWN 2 MESH NETWORKS IN THE SAME ENVIRONMENT TROUBLESHOOTING: UNSTABLE NETWORK BUT GOOD RSSI VALUES MAXIMUM NUMBER OF REPEATERS (MESH NODES) BETWEEN AN END NODE AND THE MESH GATE “HOPS COUNT” VALUE FOR ANY DEVICE IN THE MESH NETWORK WI-LEM: MODBUS APPLICATION COMMISSIONING DONE BY COMMUNICATING WITH THE MESH GATE THROUGH MODBUS OR MESH SCAPE NETWORK SOFTWARE MANDATORY TROUBLESHOOTING: THE VALUES REPORTED BY THE MODBUS APPLICATION SEEM INCORRECT (IE. DOUBLE OF WHAT WAS EXPECTED) SET THE UTC TIME IN MESH GATE EACH TIME IT IS SWITCHED ON RECOMMENDED POLLING INTERVAL ON MODBUS COMMUNICATION WITH THE MESH GATE RESETTING THE COUNTERS (ACCUMULATED VALUES) IN AN EMN EMN’S MODBUS REGISTER WRITING TAKES SEVERAL MINUTES WI-LEM: ABOUT THE EMN EMN ACCURACY EMN’S LED IS NOT BLINKING MINIMUM CONNECTIONS REQUIRED FOR AN EMN EMN’S LED BLINKING 3 TIMES EMN’S LED BLINKING 5 TIMES NEGATIVE ACTIVE ENERGY NEGATIVE REACTIVE ENERGY DATA REFRESH PERIOD FOR EMN REGARDING COUNTERS AND ACCUMULATED VALUES APPROXIMATELY 1 MINUTE! DATE & TIME UPDATE IN EMN DECREASING THE EMN DATA REFRESH PERIOD TO GET HIGHER REPORTING RATE INSTALLING AN EMN INSIDE A METAL CABINET MINIMUM DISTANCE BETWEEN SEVERAL EMNS INSTALLED ON A DIN RAIL INSTALLING THE EMN CASE OUT OF THE CABINET WHERE THE CTS / RTS SHOULD BE (E.G. DUE TO LIMITED SPACE) EMN COUNTERS OVERFLOW (ACCUMULATED VALUES) EMN’S INTERVAL-BASED ENERGY REGISTERS OVERFLOW WI-LEM: ABOUT MESH NODE AND OTHER DEVICES MESH NODE’S PWR LED IS OFF WHILE EXTERNAL DC POWER SUPPLY IS CONNECTED CHECK THE INTERNAL ON / OFF SWITCH.
