Note!If the errors listed above occur, these are displayed inthe Home position flashing continuously.•General:These error messages can be reset by configuringany batching parameter. It is sufficient to confirmwith the OS key and then the F key.• Batching via status input:The error message can be reset by means of a pulse.Another pulse then restarts the batching.• Batching via operating keys (soft keys)The error message is reset by pressing the STARTkey. Pressing the START key a second time startsthe batching process.• Batching via the BATCHING PROCESS function(7260):The error message can be reset by pressing theSTOP, START, HOLD or GO ON keys. Pressing theSTART key a second time starts the batchingprocess.• Batching via Modbus:The error message can be reset via Modbus byselecting 4 = RESET in the "BATCH PROCEDURE(7260)" parameter.Page 96 • MN0M030Issue/Rev. 0.2 (12/12)

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
