keyword=strange fan read out behavior
We notice a raise in the readout of the fan speed value that is probably not physical because it reach a value that was around 500 Hz.
The main target control is reading the usual value of 48 Hz. The loop temperature (7 K) I read from the video screen is stable like the other values in the main screen. Only the LOOP1 stripchart (heat_Load_LOOP1) is showing this behavior.
We decided to restart the IOC and after the stripchart read 0 fan speed. The stripchart fan value went to zero after the IOC reboot.
Others readout looks fine.
