Answer / Omendra Jeet Pal

1) A frequency inverter converts fixed frequency AC power into variable frequency AC power.n2) To ensure proper operation of connected frequency inverters on a network, configure them with unique IP addresses and set communication protocol parameters.n3) The input sensor for a weigher is typically a load cell.n4) To confirm that a load cell is faulty, compare its output with known weights or consult the manufacturer's specifications.n5) Steps to validate a weigher:n a. Verify electrical connectionsn b. Check calibrationn c. Test with known weightsn6) Procedure to validate flowmeter accuracy:n a. Install a calibrated reference flow devicen b. Compare the measured and reference flow ratesn7) Steps to validate temperature sensor/transformer:n a. Verify electrical connectionsn b. Check calibrationn c. Test in controlled temperature environmentsn8) Adjustment for calibrating temperature transmitter varies depending on the device, refer to manufacturer's instructions.n9) Safety measures before disconnecting a motor for rewinding include:n a. Lockout/Tagout proceduresn b. Ensuring power is offn10) Synchronous speed in rpm of a typical 4-pole, 50Hz motor is approximately 3000rpm.n11) The formula for kW is Power = Voltage * Current * Power Factor.n12) If a 3-phase motor is rated 3kW, 415Vac, its rated current can be calculated as Current = Power / (Volts * Power Factor).
