Introduction
Using state-of-the-art microprocessor technology, the
DC Motor Controller Board provides protection and
operational advantages over "hardwired" DC motor
actuators. A current sensing circuit continuously
monitors motor operating conditions. When stalled or
abnormally high motor current exists, the controller
automatically shuts power off to the motor. Current
sensing protects not only dc motor brushes from
destruction, but also protects power supplies during
fault conditions, including solar recharging systems
from extreme battery discharge. A fault latching circuit
will maintain this off status until an input direction
change is detected to reset the latched controller for
normal operation.
The current sensing circuit and initial setup procedures
use on-board local control switches and adjustments.
Local control and LED status indicators ease calibration
by eliminating special test measurements and control
room activity. Remote operations are accomplished by
2-wire switching from PLC's, dry contact relays or
switches. A 2-wire "brake" control is optionally used for
mid-stroke positioning.
The AUTOMAX DC Motor Controller Board conveniently
mounts inside Centura CE Series Electric Actuators. The
CE actuators' unique housing design satisfies NEMA 4,
4X, 7, and 9 ratings simultaneously, providing indoor
and outdoor protection in industrial applications
including gas and oil, pulp and paper, oil patch sites,
and chemical processing.
