The PDU's RFI AMP Circuit Breaker Trips When 3T 35KW MKS Amplifier Tries to Go Ready due to the 3T 35KW MKS Amplifier.
Symptom
The PDU's RFI AMP Circuit Breaker Trips When 3T 35KW MKS Amplifier Tries to Go Ready When powering on the 3T 35KW MKS Amplifier, the LCD readout power on sequence counts down 4, 3, 2, 1. When it hits "1", presumably when high voltage is applied, the PDU's RFI/AMP circuit breaker trips. There are never any errors displayed on the Amp. Once in awhile, on repeated tries, the circuit breaker will stay on after the power on sequence completes, but then it trips with the first pulse of the first prescan. See long Description for the errors logged by the system when this happens. When powering on the 3T 35KW MKS Amplifier, the LCD readout power on sequence counts down 4, 3, 2, 1. When it hits "1", presumably when high voltage is applied, the PDU's RFI/AMP circuit breaker trips. There are never any errors displayed on the Amp. The errors shown below are logged in the message log upon system reboot or TPS reset. Once in awhile, on repeated tries, the circuit breaker will actually stay on after the power on sequence completes, but then it trips with the first pulse of the first prescan. 2223817 mr3t NSP TardisReset.cc 392 TPS is not responding.
