Note!Please observe Note in error message No. 471128 PROGRESS NOTE 473 P: PROGRESS NOTE$: # 473End of filling processapproaching.The running filling processhas exceeded the predefinedbatch quantity point for thedisplay warning message.No measures required (if necessary prepare to replacecontainer).151 > MAX FLOW RATE 474 P: MAX. FLOW RATE!: # 474No. # 7xx Other process errors111 EMPTY PIPE 700 P: EMPTY PIPE!: # 700Maximum flow value enteredis overshot.The process fluid density isoutside the upper or lowerlimit values set in the "EPD"functionCauses:– Air in the measuring tube– Partly filled measuringtubeReduce the flow value.! Note!Please observe Note in error message No. 4711. Ensure that there is no gas content in the processliquid.2. Adapt the values in the "EPD" function to thecurrent process conditions.112 EXC. CURR. LIM 701 P: EXC. CURR. LIM.!: # 701The maximum current valuefor the measuring tubeexciter coils has beenreached, since certain processfluid characteristics areextreme, e.g. high gas or solidcontent.The instrument continues towork correctly.In particular with outgassing fluids and/or increasedgas content, the following measures are recommendedto increase system pressure:1. Install the instrument at the outlet side of a pump.2. Install the instrument at the lowest point of anascending pipeline.3. Install a flow restriction, e.g. reducer or orificeplate, downstream from the instrument.113 FLUID INHOM. 702 P: FLUID INHOM.!: # 702Frequency control is notstable, due toinhomogeneous process fluid,e.g. gas or solid content.Issue/Rev. 0.2 (12/12) MN0M030 • Page 97
