The control system is critical to the proper operation of the
pump system. The control system stores all of the operating parameters
for each casting job. In some gravity-pour applications, this can
amount to many hundreds of "fill profiles." Each fill profile is stored
on an industrial PC and is downloaded to the PLC at the beginning of each
job run. Programming of fill parameters is performed by an authorized master
operator. But any authorized operator can download fill profiles at any time.
Typical fill profiles consist of up to 16 segments of specified time of a specified
power. As the profile runs, the pump power is varied according to the
programmed fill profile. Since the pump has no moving parts, the only
inertia in the system is that of the moving metal itself. This means that the
pump delivery pressure can be changed almost instantly to meet the requirements
of the casting. Numerous safeguards are standard in the control system to meet
safety standards throughout the world. Control systems can also be provided with
the capability to report to external systems for such things as SPC and other
managerial data systems.
