Operator gets error window message below when attempting to run a damper test (Figure 1):
The test was stopped.
The following Signal was not found by the TSIIS controller:
Make sure the API reference in the MTS Damper Controller
Error: SapiDataAcqAddChannel()-> dataAcq()->AddChannel()
Figure 1 – Damper Error Window
This error indicates that API reference for signal load in the Damper Controller Configuration Setup does not match that in Station Manager.
In Station Manager go to the Display menu > Station Setup > Channels. Check the names of your channel and control modes. In this case the channels signals names were Axial Displacement and Axial Force (Figure 1).
Figure 1– Station Setup channel signal names
Open the MTS Damper Controller Configuration Setup. Go to the Edit menu > Edit (Figure 2)

In the Control Channel Parameters window make sure that the AP I Channel Name and associated signals are the same as in Station Setup in Station Manager; Axial Displacement and Axial Load (Figure 3).
