XCell
TM
ATF System with C410:V3 Controller
WEIGHT TREND
Available in the TRENDING screen
During the XCell
TM
ATF System cycle, the weight of the Filtration Assembly changes in
response to the liquid flow to and from Diaphragm Pump. The weight profile is directly
proportional to the position of the diaphragm within the Diaphragm Pump, (or to how much
liquid is in the Diaphragm Pump). This provides useful real time information on the position
of the diaphragm within the Diaphragm Pump.
That information may be used to:
i. Monitor if the diaphragm cycles its full stroke.
ii. Display the position of the diaphragm in the Diaphragm Pump.
While the PLC records the output from the load cell in milliseconds, the computer
HMI is much slower and refresh rate is about once every 0.5-1.0 second; therefore,
while one may not observe the details of the pump cycle on the HMI, (typically,
between 4-10 seconds/half cycle), the PLC will continue to monitor the rapid weight
change.
The Operator can view C410:V3 controller Warnings and Alarm conditions. All
Warnings/Alarms are displayed with Time/Date stamping and full description of
condition. Both Warnings/Alarms will activate the audible horn located inside C410:V3
controller cabinet. An Alarm condition will automatically stop the pump cycling action,
while a Warning condition allows the pumping cycling action to continue. Warning and
Alarm conditions are described in the following section.
