Introduction; Readouts And Controls - MICROPUMP 75211-20 Manual De Operación

Each of these Motor/Controller Systems incor porates a high-torque magnetic coupler and a
0.1 horsepower DC motor, designed for driving MICROPUMP
has long brush life, has increased torque at high speeds, is totally enclosed and permanently lubricated. The Motor/
Controller System automatically compensates for changes in load torque demands. Utilizing an electronic control
circuit, the Controller assures accurate, dependable motor speed (flow) control with "soft start" and smooth gradual
acceleration to the speed setting. Motor current limiting protects the system in case of a locked rotor condition and
assures magnetic lock over wide load variations. Output circuit protection protects against inadvertent output shorting.
Built-in motor current compensation minimizes no-load to full-load speed variation. Excellent speed regulation and
improved line noise immunity, even with line voltage and load variations, is designed into the electronic control.
Included in this manual are Application, Description, Installation/Setup, Operation, Troubleshooting and Maintenance
and Specification Data.
