12:30-1:00: Met with Terry Robinson PE of Pro-West Engineering and Chuck
Collins of Argus Electric at the Eagles Nest Café. Explained problems with
programmable logic controller at the City well-house while they ate lunch.
1:00-6:45: Met at well-house with Terry Robinson, Chuck Collins, Dave Conner,
Nick Conner, and Jake Claridge. Dave and Nick placed Badger M-2000 mag-meters
into calibration mode so Terry could calibrate programmable logic controller
for input from the meters. Dave noted one of the inputs on the plc need to be
changed to 4-20 mA and Terry corrected it. Terry updated plc programming so
chlorinator frequency control could be adjusted from the plc interface giving
the city the ability to properly chlorinate the city’s drinking water once
again. Added to the interface were controls giving the ability to disable a
pump and have the pump in service always act as lead pump allowing the pump to
run between the normal pump on and pump off conditions eliminating the low
water alarm caused by the pump running between lag pump on and pump off
conditions. Terry also exhibited how to reset the interface being careful not
to reset it to the default settings; he then demonstrated how to change the
pump to waste setting if the need ever arises.
At about 4:00: Dell laptop with windows 7 and i7 processor running a program in
virtual machine froze up. It guy from Pro-West remotely got the computer up and
running again with an earlier version of the programming file. Some of the
updates had to be reincorporated back into the file. Went to city hall and
brought back three chairs.
At about 6:30 Terry had the programming for the plc completed and looking good.
Also noted during the day by both Chuck and Dave was excessive vibration coming
from pump 1 while running. Pump 1 motor is leaking oil from top and flowing
down side of motor.
