Monday afternoon there was no control of the vacuum system. The controls were working, but no output to devices. The "output" breaker in the PLC box was found to be tripped. Reseting it allowed control to the vacuum systems.
I started the regeneration of BCP2 this morning, but hte output breaker tripped again. reset it and continued to pump.
Started to pump out the solenoid also. Removed jumper on the BDP2 temperature read-back, bypassed BV2, and BCG2. This allows pumping through the diffussion pump.
Cold box has been pumping for a few weeks. It's at 2.0 x 10-3 |
