r, <br />• III IIIIIIIIIIIIIIII <br />Instrumentation Log <br />Author: Victor Gurule <br />Date: February <br />2/3/92 <br />1) Cleaned all Ph probes and calibrated all ph probes. <br />2) Worked on getting all the Cyanide pump to leach working in <br />auto or remote. <br />3) The pressure modulating valve on 208 was leaking so I <br />turned off the valve. The water was spraying onto the SAG <br />mill. <br />2/4/92 <br />1) Showed Steve and Alfred our computer system in the mill <br />and the ware house. <br />2) Worked on making a banner for Gary Dodson. <br />3) Installed a new piece of poly pipe on the CIL tank 3 dart <br />valve. <br />4) Steve and I got the spare module on the network going. <br />5 Joel was concerned that the flow comming out the <br />thickener under flow pump was not reading accurately. So I <br />made several diagnostic checks and everything seems to be <br />working fine. <br />- note need to call rosemont concerning the accuracy of the <br />magnetic flow tubes and the possibility of electrode erosion. <br />2/5/92 <br />1) Spent most of the day working on the temperature indicator <br />on the discharge to the elution column. <br />i. ran wire from the device to the marshaling cabinet. <br />ii. powered up the device and checked for proper <br />response. <br />iii. tried to calibrate the device at the end of the day <br />but the signal comming out of the device was fluctuation <br />badly. <br />2) Helped operations with a couple alarming problems. Changed <br />the severity of the cyclone low density alarm. <br />3) Modified the database in the ipds logic to accept the new <br />parameters for the new temperature gauge on the strip column. <br />2/6/92 <br />1) Finished the calibration of the new temperature gauge on <br />
