Function Description

Oxylog 1000

3.4.6

Gas Supply Failure
Warning (Pv)

If the gas supply fails or falls below a defined pressure, the Oxylog 1000
delivers two alarms:

–

Visual alarm indicator "Pv"

–

Audible alarm (alarm generator)

The alarm is triggered under the following conditions:

–

The pressure of the gas supply from the central supply system or from the
O

cylinder is inadequate or absent

–

The valve of the O

cylinder is closed

–

The gas supply connector is incorrectly installed
