Cryo CAMAC Crate 12 in the South Linac alarmed on a crate controller error rate when the temperature elevated at that location (as measured by analog_Temp_ch2_12).

Placing a fan in proximity to the Crate seems to have alleviated the alarm.

OM05 in the NA went into alarm tried local calibration but wouldn't calibrate (low output error). Will investigate cause of error but bypassed sensor for now.
