061A1047A PJS 11/17/20 01012PJS1 BASED ON COMMENTS FROM RAVEN'S TECH SUPPORT, <br /> ONE MAJOR PROBLEM WITH SENSOR LIFE IS FRACTURE OF <br /> THE COPPER WIRES AT THE JUNCTION OF THE SENSOR <br /> HEAD AND CABLE. IN ADDITION TO PREVIOUSLY <br /> INSTALLING THE SENSOR HOOK FOR THE NEWER STYLE <br /> 1111 SENSOR, PVC HALF-ROUNDS FOR THE REEL CORNERS, IT <br /> WOULD BE SENSIBLE TO INSTALL A LABEL ON THE <br /> HANDLE TO WARN AGAINST SHOCK/EXCESSIVE FLEXING <br /> AT THAT SENSOR HEAD JUNCTION. Installed caution label on <br /> 061AI064A(SSC/RAS currently in Admin),061AI065A(SSC/RAS <br /> currently in Admin),061A1066A(SPARE currently used at GT),and <br /> 061AI048A(GT but currently used at SSC/RAS). Unable to find <br /> 061A1047A(GT). <br /> 061A1048A PJS 4/16/20 00410DRF1 REACHING HIGH WHEN METER IS ON. SENSITIVITY AT <br /> MINIMUM. Replaced controller board assembly and cable/sensor <br /> head assembly. <br /> 061A1048A PJS 8/20/20 00808CFB1 RAVEN FROM GT PUMP STATION.ACTS LIKE A SHORT OR <br /> OPEN AT JOINT WHERE WIRE AND SENSOR HEAD MEETS. <br /> Replaced cable/sensor assembly and ordered new one for warehouse <br /> stock. <br /> 061 A1064A PJS 2/25/20 00221WM1 WHEN TURNING THE RAVEN ON ALL THE LIGHTS COME <br /> ON WITHOUT BEING IN THE SLUDGE. FROM RAS PUMP <br /> Loose connection on circuit board. Weak batteries. Repaired.Now <br /> OK. <br /> 061 AI064A PJS 6/30/20 00619JAK1 FRESH BATTERIES. METER READS FULL WITH NOTHING <br /> BETWEEN THE SENSOR. Broken internal wire in cable by sensor <br /> head.This is the old-style grey cable black sensor. Replaced with new <br /> style yellow cable stainless steel sensor.Tested OK.Ordered new <br /> cable/sensor for warehouse stock. <br /> . 061AI065A PJS 3/5/20 00226PJSI RAVEN CONTINOUSLY ALARMS WHEN TURNED ON. Raven <br /> alarms when weight of sensor head pulls on cable.At least one wire is <br /> fractured inside cable going into sensor head.Ordered new <br /> cable/sensor assembly. Installed new sensor/cable.Tested OK. <br /> 061 A1065A PJS 10/8/20 01008PJSI WIRE LOOSE IN SENSOR HEAD. Replaced cable/sensor(factory <br /> warrenty). Receiving replacement for free. <br /> AI-065 PJS 8/12/20 00803PJS3 ROSS PH PROBE FOR AI-065 PORTABLE PH METER NOW <br /> ONLY CALIBRATES IN MANUAL MODE, WILL NO LONGER <br /> CALIBRATE IN AUTO MODE EVEN AFTER CLEANING AND <br /> CHANGING ELECTROLYTE.NEED NEW PROBE.Ordered new <br /> probe. Rich installed new probe on 8/12/2020. <br /> AI-065 PJS 12/3/20 01125PJS1 PH PROBE WILL NOT CALIBRATE IN AUTO MODE,ONLY IN <br /> MANUAL MODE.NEED NEW PH PROBE.CURRENT ONE IS <br /> MORE THAN ONE YEAR OLD.Ordered pH probe 11/25/2020. <br /> Received,installed and calibrated on 12/3/2020. <br /> AI-070 PJS 11/17/20 01015PJS1 ALTAIR 5X WAS LOANED TO CONTRACTOR AT RIVER <br /> ROAD. RETURNED WITH PLUGGED 25 FOOT SAMPLE LINE <br /> (MAINT)AND PLUGGED FILTER.CLEANED OUT QUICK <br /> DISCONNECT,HYROPHOBIC FILTER,AND FINAL SAMPLE <br /> ROD, BUT WAS UNABLE TO UNPLUG 25 FOOT SAMPLE <br /> LINE.NEED TO ORDER NEW SAMPLE LINE. Plugs were in the <br /> extension cable and it's hydrophobic filter but not in the Altair 5X gas <br /> detector.Could not blow out plug in tubing so replaced tubing and <br /> ordered MSA spares.Ordering a 100 foot roll of generic Teflon <br /> • tubing and will just swap fittings from now on since the material cost <br /> of generic Teflon extension tubing is only 14%the cost of an official <br /> MSA extension tube and will work just as effectively. Since the cost <br /> of the tubing is so inexpensive($22 per 25 foot section)there is now <br /> no need to sheathe it with the yellow thread protector mesh. <br /> Page 13 of 20 <br />
