GE CT Lightspeed LS3.X errors 183182 and 214080
August 13, 2019 10:42
I am dealing with GE CT Lightspeed LS3.x
I am getting an error 183182 on Tube Warm up
i/o board pilot relay are closed. PDU pilot relay not energized. BCSTAT=0; HVDC rail voltage=215v.
and getting an error 214080 upon KV & mA test
HVDC BUS Voltage is present while backup contactor pilot relay indicates a de-energized state, gentry i/o relay k251 and k245 are energized
hvdc bus voltage:210 V
gentry i/o address:FFAFBFH, bit:D4 expected 1 actual :0
Please guide me through the right Troubleshooting Flowchart to figure out the root cause of these errors.
Upon turning off the power at the PDU, I tested the resistance across A2TS1 cables at the PDU and these were the readings:
Red to Ground 53 K ohm
Black to Ground 50 K ohm
Black to Red 451 Ohms
I tested the phase to phase voltage at the input to the PDU and all read around 380VAC, and phase to ground around 215VAC.
Your help is much appreciated.
