*UART ERR - System UART malfunction.
Possible cause for the *UART ERR communication error message include:
A. Electronic component failure on the Level Plus Monitor communication board.
Communication error message on individual RTD display example.
An example of a system error message is shown below.
System error message example.
The *PRGRM ERR system error message indicates that Level Plus monitor is incorrectly pro-
grammed. Possible cause for the *PRGRM ERR system error message include:
A. The Level Plus monitor 'number of floats' parameter is set equal to 2 floats and the DDA
tank gauge internal 'number of floats' parameter is programmed for 1 float.
Other system error messages and their possible causes are listed below.
*FLOAT ERR - DDA tank gauge not receiving expected return signals from floats.
Possible causes for the *FLOAT ERR system error message include:
A. DDA tank gauge internal memory set for 2 floats and only 1 float installed on gauge.
B. DDA tank gauge float(s) allowed to enter inactive zone at tip of gauge.
C. Malfunctioning DDA tank gauge.
*GAUGE ERR - Hardware malfunction detected from DDA gauge level measurement circuitry.
Possible cause for the *GAUGE ERR system error message include:
A. Malfunctioning DDA tank gauge electronics.
