Foxboro E69F Converter

During maintenance, it is recommended to record the model number, input range, positive and negative effects, output code, electrical classification, range setting, optional components, actual installation position, supply voltage value, and zero/range calibration value. Check the air source filter and output meter every six months, and verify the zero position at the actual installation location every year; Before replacing the FBM or valve, confirm the direction of action of the converter to avoid process fluctuations caused by "reverse valve opening". When replacing a discontinued old converter, don't just look at its appearance and interface. First, compare the six items of "shell - B/- T, input I/H, output 2/3/7/8, positive and negative effects, electrical classification, options J/M/P/R/S" one by one, then check the supply pressure, air consumption, and output capacity, and finally calibrate at the actual installation position. This can not only avoid misuse in explosion-proof areas, but also reduce common problems such as zero drift, insufficient output, and reverse action.
