8. Maintenance
The optional PC Configuration Software cannot be used while a test mode is active.
All events generated while the system is in test mode will be logged in the event history. Therefore a record
of the testing can be generated once it is complete (see Normal Operation, Generate Reports).
8.1.2 Field Inputs Test
Note: Engineer access level is required.
During this test, all field device inputs will be displayed by the Touchpoint Pro system, 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 of
the Touchpoint Pro system. Typically, this can be done either by applying 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 be viewed on the touchscreen or the Web Server.
