Pulsafeeder MPC - Manual (Page 6)

1. Introduction
The Metering Pump Controller (MPC) is a microprocessor based motor speed
control device, for use with Pulsafeeder mechanical and hydraulic diaphragm
metering pumps. It has been designed for simplicity, yet still has many advanced
features that allow the MPC to operate in a wide variety of environments and
applications.
This instruction manual covers the MPC only. All standard features are covered
in this manual and most options have instructions where applicable. For
information specific to the metering pump or any other accessories, please refer
to the appropriate IOM.
2. Forward
The pumps to which these “instructions” refer to are designed for use in industrial
areas and therefore cannot be treated as retail products. The present
documentation gives instructions to be used by qualified personnel only. It must
be used in compliance with the regulations, laws and technical standards in force
and cannot, under any circumstances, take the place of plant standard or
additional regulations, including any which are not legally enforceable, which
have been issued with the scope of ensuring safety.
Equipment with special manufacturing or constructive variances may differ in
details with respect to this description.
In case of any difficulty, please contact PULSAFEEDER, INC. Technical Service.
The MPC is rated for NEMA 4x locations as identified on the controller
nameplate.
3. Description
The MPC is an advanced pump controller that is physically attached to the
pump. Its purpose is to precisely adjust output flow of a process media by
means of pump motor speed control.
The MPC is designed for a wide variety of control applications. The device is
factory configured and calibrated for the attached pump. The human/machine
interface is user friendly. Local setup and control is achieved through the
keypad and a backlit two-line liquid crystal display. Basic operation is simple
with dedicated function keys eliminating the need for a sophisticated menu
system. The MPC responds immediately to user commands. Pump output is
displayed as Gallons per Hour (GPH), Liters per Hour (LPH), Strokes per
Minute (SPM), Percent Speed, or Percent Flow (% of total pump capacity).
Digital and analog inputs will support a variety of industry standard signals to
offer flexible remote control.
The MPC is designed to simplify and automate the calibration of pump flow and
analog signals. Flow calibration uses on-screen prompting and automated
pump operation to eliminate stopwatches, calculators and human inaccuracies.
Analog signal calibration is also accomplished by simple keypad entry. It
