Fehlerbehebung
The most common form of communication used with the SMRT units is via ethernet. In this case if the communication cannot be established it is important to check that RTMS is enabled in the local firewall. Sometimes the antivirus installed on the computer will block the ethernet communications. Sometimes the reason for the failure to communicate is that the IP addresses of the unit and the PC are not on the same subnet. Changing the IP address of the unit or the PC to be on the other’s subnet will fix the issue. It is even better to leave the SMRT in DHCP mode so that it takes an IP address in the same subnet as the PC connected to it. If the SMRT’s IP address has been set to a fixed value, it is possible to force the unit into DHCP mode using RTMS.
When serial communication such as USB or Bluetooth is failing the culprit is usually the port number used which can be checked on the device manager.

Things to check:
In the SMRT/RTMS - Is the binary input on the SMRT configured as wet or dry contact? Does it correspond with the relay’s binary output’s operation?
Is the type of operation selected properly? i.e. Normally Closed or Normally Open contact?
Did you choose the proper input as trip? Sometimes the SMRT is connected to the proper output on the relay, but RTMS is expecting the trip input on a different input.
In the relay - Is the test signal used adequate for the test? If we are testing a 51 pickup, we cannot use the timing signal to trip and vice versa.
Did we assign the trip to the proper output on the relay?
Is there any condition blocking the trip inside the relay?
Did we use the proper polarizing signal?
In the SMRT46 or SMRT46D units the battery simulator doubles as the fourth voltage channel. For this reason, if you see the 4 voltage channels on the home screen that means that the battery simulator is not activated. If that’s the case, go into the configuration screen by clicking on the “gearbox” button and click on the Use “Last V as Battery” button. When you go back to the home screen, you’ll see that you no longer have a 4th voltage channel available, and the battery icon has been enabled.
In RTMS files can be saved as active documents in an XML file with a format called pdbxml. Those PowerDB documents can be reused to retest the same relay or to test a different relay of the same model.
Another possibility is to save the test results into a PDF file directly from RTMS.
Auswertung der Prüfergebnisse
For each test the RTMS report provides a visual indication about the status of the test. The tests will show as either not performed, incomplete, failed or passed.
RTMS evaluates the status of the report and provides a pass or fail criteria for it based on whether all the tests have passed or not. All the tests must have a status of passed for the report to have a passed status. Each test is time stamped clearly indicating the date and time when the test was performed.
Each test is evaluated using criteria specific to the test. For some tests the tolerances can be set directly on the report whereas for others they must be set inside the test form prior to performing the test. The specific values for the tolerances used are the responsibility of the user and should be found either on the manuals for the specific relays or selected from the local test procedures.
