    "match" of the electronics, cables and ultrasonic sensors. Consequently some flow offset (or zero offset) may be present in any installation. To eliminate this residual zero offset Siemens has developed several different methods to insure proper zero flow compensation. The following paragraphs describe each method and when they should be used.
  • Page 74 Functions 7.2 Zero Flow Adjust Menu ZeroMatic When ZeroMatic is invoked the flow meter first performs the same analysis as described above in the AutoZero routine. However, after this analysis is complete the flow meter continues to interrogate the pipe wall signal and update the zero offset value under normal operation, such that the flow meter dynamically compensates for changing conditions which would normally result in zero drift.
  • Page 75 Functions 7.2 Zero Flow Adjust Menu Using ReversaMatic If site conditions do not permit stopping the flow rate at the mounting location, and you do not know the current flow rate, then you can use the ReversaMatic routine to establish the zero flow level.

    CAUTION The Force Transmit and Force Frequency diagnostic procedures are preconfigured at the factory and should only be implemented by approved Siemens personnel. This diagnostic software routine allows the user to "force" a transmitting condition that can be used to search for an amplitude level (ALC) when Detection Fault or Low Signal alarms are present.

  • Page 111 Troubleshooting 10.3 System Reset The reset sequence operates on two levels. ● The first level deletes all the data currently in Active Memory, but leaves Datalogger data and all stored Site Setups intact. This is the most desirable method since to restore operation all you have to do is reload a saved Site Setup.
  • Page 112 The impact of this is such that we strongly recommend that you consult the Technical Service Department (http://www.siemens.com/automation/service&support) before continuing with this procedure. If you choose to continue, be aware that you will have to create a new Site Setup, re-enter all site specific parameters including pipe or sensor tables, plus all desired Meter Facilities entries.
