Read a steady <br /> 4ma signal.simulated up to 20ma signal,all seemed ok. Landed wires <br /> back onto mass unit and readings became steady. <br /> SWGR105C MJN 4/22/20 91213MJN1 WORK WITH MANUFACTURER TO IDENTIFY A <br /> REPLACEMENT FOR THE FAILED METERING DISPLAYS. <br /> ASSIST MANUFACTURER WITH INSTALLING NEW <br /> DISPLAYS----Assisted Eaton with installing new displays and <br /> compatable meters. <br /> SWGR1 05D MJN 5/18/20 91213MJN2 WORK WITH MANUFACTURER TO IDENTIFY A <br /> REPLACEMENT FOR THEFAILED METERING DISPLAYS. <br /> ASSIST MANUFACTURER WITH INSTALLING NEW <br /> DISPLAYS----Assisted Eaton with installing new displays and <br /> compatable meters. <br /> 106 NORTH#3#4 PRIMARY CLARIFIERS <br /> ITEM BY C-DATE W/O# <br /> 106 BJL 2/13/20 00202KJW2 LIGHT BULB IS OUT ON THE NUMBER 2 POLE FOR THE <br /> NORTH PRIMARY CLARIFIER#4----Replaced photocell and light <br /> bulb. • <br /> SEP106WWP04 MJN 9/9/20 00819RJJ1 SKIMMER SWITCH TIMER IS ALARMING AS EXPIRED <br /> TIMER.---Replaced worn out whisker on timer switch. <br /> 08-31-2020 replaced entire switch. <br /> 09-08-2020 New whiskers keep failing on switch.two so far.replaced <br /> whisker again and moved targets away from switch so they are not <br /> putting so much pressur on whiskers. <br /> 108 NEW NORTH PRIMARY PUMP STATION <br /> ITEM BY C-DATE W/O# <br /> 108FCVIOIA EC 4/10/20 00408WM01 THE SOELNOID FOR THE VALVE IS HUMMING.----Replaced <br /> solenoid and tested equipment. <br /> 108FIT121A PJS 7/20/20 00713JMG1 FLOW METER GIVES A"HIGH PROCESS NOISE"ALARM ON <br /> METER.GOOD FLOW(225 GPM).NO DCS ALARM. HPN alarms <br /> on these Rosemount magmeters at Willow Lake are caused by air <br /> bubbles,noise from high solids content,or rapidly changing flow <br /> rates.The usual way to alleviate this is by increasing the exitation <br /> frequency at the expense of some instability during times of zero flow. <br /> Checked flowmeter again on 7/15/2020 and there was no"High <br /> Process Noise"alarm. <br /> Note: The coil frequency was set at 37 Hz and the meters were zeroed <br /> on all three magmeters during commissioning(108FIT121A, <br /> 108FIT122A, 108FIT123A). It occured on the weekend of • <br /> 7/18-19/2020 as well. <br /> Page 18 of 20 <br />
