DWA-2000A-SS Suspended Solids Controller 11. Measurement of SS Caution ￭ Be sure to perform calibration before installation When power is initially supplied, SS density values will appear real time on the FND. When the RUN lamp blinks, it indicates that analog output (4~20mA) is generating When it does not blink, the analog signal is not being produced. -
