3.3 Normal Operation
In normal operation, the OLCT 700/710 Display continuously shows the current detector
reading, which will normally appear as "0". Once every 60 seconds the LED display will flash
the detector's measurement units and gas type (i.e. % LEL). If the detector 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, PGM1 or PGM2 can be swiped to prompt the detector
to display the list of the active faults.
In normal operation, the 4-20mA current output corresponds with the present gas concentration
and full-scale range. The RS-485 Modbus™ serial output provides the current gas reading and
fault status on a continuous basis when polled.
Caution: Off-scale readings may indicate a flammable concentration of gas.
