Analysis and countermeasures when the Rosemount transmitter cannot be powered on.
1. There is something wrong with the leakage circuit breaker itself
When the jump bar indicator and power indicator are not on, it is necessary to check whether the fuse is blown; whether the transformer, voltage regulator manifold, and power switch are damaged; Whether the power supply of the leakage protector is normal. The solution is to use the multimeter 500V voltage block to measure the power supply voltage of the leakage protector, if the voltage is normal, you can use the power failure to separate the power switch, internal connection line, fuse and transformer, and replace the damaged or repaired components after finding the fault; If the voltage is very low or there is no voltage, check the wiring to solve the problem.
2. Contactor fault
If the Rosemount transmitter has problems such as coil burning, poor contact at the joint, etc., the corresponding treatment method is: replace the coil, tighten the screws or weld the joint, use the 500V voltage block live measurement or use a multimeter ohm to measure the voltage at both ends of the coil, determine whether the coil is open, and then check whether the moving iron core block has any blocking phenomenon.
3. The pressure transmitter is not equipped with a leakage circuit breaker and the circuit of the device leakage circuit breaker is electrically connected
Find out whether the indicators, lights, temporary lights, appearances and other electricity on the distribution board or control cabinet are connected on both sides of the zero sequence current transformer, adjust the wiring, and the wiring of the same load should be connected in front of or behind the unified zero sequence current transformer.
