Operation
A pump draws air samples from the cabinet interior through the sample tube into the gas monitor.
When the sample proves below the LEL the power outlet is energized, If at anytime the sampled air rises above
the LEL, power is disconnected while an audible and visual alarm are energized.
When enegized (during warmup), a green LED will blink on the detector indicating that the unit is testing for the
existence of explosive gasses in the cabinet. This test will take approximnately one inute to complete. If no gas is
detected, the unit will supply power to the internal power outlet.
