    keyword=LH2 sensor

    17:15 MCC phoned about a H2 sensor (on CH004 of the FSD overview screens) which is faulted. We do not see a target problem and called in K. McCormick. MCC says in the past this HAD been masked but is now not. Jack Segal was paged and asked us to verify the GasMaster was not alarming (it is not). Dave Meekins is coming in to take a look and we have requested a hall access.
    17:30 MCC phoned. They believe the fault is in the dump. MCC has called in AES to take a look.
    17:55 MCC calls again. The sensor is running about 12% and the trip point should be 50% so they are going to mask the sensor and try to re-establish beam.
