Operation Proline Promass 835.3 Error messages5.3.1 Type of errorErrors that occur during commissioning or measuring are displayed immediately. If two or moresystem or process errors are present, the error with the highest priority is the one shown on thedisplay.The measuring system distinguishes between two types of error:• System error:Includes all device errors, e.g. communication errors, hardware errors, etc. ä 86• Process error:Includes all application errors, e.g. fluid not homogeneous, etc. ä 91Fig. 32: Error messages on the display (example)1 Error type: P = process error, S = system error2 Error message type: $ = fault message, ! = notice message3 Error designation: e.g. "FLUID INHOM." = fluid is not homogeneous4 Error number: e.g. #7025 Duration of most recent error occurrence (hours: minutes: seconds)!Note!5.3.2 Error message typeUsers have the option of weighting system and process errors differently, by defining them as Faultmessages or Notice messages. You can define messages in this way with the aid of the functionmatrix (see the "Description of Device Functions" manual).Serious system errors, e.g. module defects, are always identified and classed as "fault messages" bythe measuring device.Notice message (!)• The error in question has no effect on the current measuring operation and the outputs of themeasuring device.• Displayed as Exclamation mark (!), type of error (S: system error, P: process error)Fault message ( $)• The error in question interrupts or stops the current measuring operation and has an immediateeffect on the outputs. The response of the outputs (failsafe mode) can be defined by means offunctions in the function matrix. ä 94• Displayed as Lightning flash ( $ ), type of error (S: system error, P: process error)• Error conditions can be output via the relay outputs.• If an error message occurs, an upper or lower signal level for the breakdown informationaccording to NAMUR 43 can be output via the current output.Page 40 • MN0M022Issue/Rev. 0.2 (12/12)
