Field Inputs Test
Engineer
access level is required.
During this test, all field device inputs will be displayed, but the
Cause and Effect
matrix will not be evaluated. No outputs
will be generated.
The purpose of this test is to check that the input field devices are connected to the correct input channel. Typically, this can
be done either by applying a test gas to the sensor in the field or by forcing the mA output of the sensor to a given value.
The gas concentration and alarm states raised for the channel can then be viewed on the Touchscreen UI or PC GUI. The
system fault relay will be open.
