Troubleshooting Plug-
in Modules
The test module acts in the same way as an external device would, and sends signals to the
VueLink module in both analog and digital form. The computer module checks these signals for
validity, and then displays “passed” or “failed” on the screen.
The Task Window displays two waveforms, a triangular one and a rectangular one. These are
displayed alternately and for a period of ten seconds each. The expected curve type is indicated
below the wave.
There are two pairs of gridlines that indicate the permitted range for the max/min values of these
waves. If all the data received by the test module is correct, the waves will lie within the specified
ranges. If either limit of either wave falls outside the respective gridlines, then the module being
tested is faulty regardless of the passed/failed messages.
The and softkeys are of no use in this test since
would inhibit the update of the “Passed/Failed” messages.
When the test is complete:
6WHS Disconnect the cable that joins the Test Module to the VueLink module.
6WHS In Config Mode, ensure that the Test Module is set OFF, and the preselected devices are
the same ones as before the test. Also, verify the settings for these devices.
6WHS Return to Monitoring Mode.
6WHS Press the Setup key on the front of the VueLink module and select the required device
using the softkey.
127( It is important to ensure that the preselected device drivers are configured exactly the
same as they were before the test (including default settings).
