3. Set-up and Normal Operation
In normal operation, the Profi-RAM display continuously shows the current sensor reading, which will
typically appear as “ 0 ”. Once every 1 minute the LED display will flash the sensor’s measurement units and
gas type (i.e. % LEL). If the 700 Gas Sensor or Profi-RAM is actively experiencing any diagnostic faults, a
“Fault Detected” message will flash on the display once every minute. When the unit is in “Fault Detected”
mode with the red Fault LED on, PGM1 or PGM2 can be swiped to invoke a display of the active faults.
