ITE TP3,4, 1S,and 4S were started successfully this afternoon. All pump current draws were below 1.5A . IG1S was switched on. I have no local controller so TP1 and TP2 on TM4 at MSP can not be checked. IG1S was hard to switch on at first. It timed out and showed error 09 code. I removed the connector back cap, and it could be switched on after. I will look on this issue.
Turbo -pumps were stopped last night at 6 pm. All four pumps worked good during check. For IG1S switching on issue, the problem either caused by over pressure(No TP1, 2 in ITE) or because coaxial cable was pinched by connector cap and caused bad contact on pin to cable. I modified the connector cap inside by opening more space for cable passing through the cap. The cap is installed back. The gauge will be switched on next week again. We keep watch on it |
