System Overview
2-9
There are 5 operating modes for a roller pump:
•
Continuous: the pump operates at a constant speed set by the user.
• Pulse: available on the primary pump only; the pump speed alternates between
a peak speed and a baseline speed. Base, Rate and Width can be adjusted
through the Central Control Monitor.
• Master/Follower: set up during configuration; involves two roller pumps in
Continuous Mode. The Follower pump demand flow rate or speed is a percentage
of the master pump flow rate or speed. The percentage can be adjusted
through the Central Control Monitor or from the pump speed control knob on the
follower pump. The pump designated as the primary or arterial pump cannot be
designated as a master/follower pump.
• Servo Control: pump speed is regulated to maintain a specific pressure or flow
rate. The pressure and flow rate setpoints can be adjusted through the Central
Control Monitor or from the pump speed control knob on the pump.
• Automatic Delivery: the pump delivers a set fluid volume or delivers fluid for a set
amount of time and then stops.
Roller pumps can be connected to safety and monitoring systems and other pumps
during configuration, followed by choosing pump responses. Roller pump response
choices are No Response, Stop, Pause, Reduce Speed and Message Only. The
choices allowed for a pump response vary depending on the type of alert or alarm
and the type of device connected to the pump.
When a connected device is in alert or alarm mode, a message will display on the
pump display.
Centrifugal Control Unit
Features
The centrifugal control unit provides an interface between the system and a
centrifugal drive motor. A disposable centrifugal pump magnetically couples to the
drive motor. The drive motor is mounted on a pole and connects to the centrifugal
control unit with a cable. The centrifugal control unit mounts on a pole and connects
to the system with a cable. The control unit can be connected to a pump receptacle
or to any of the module receptacles.
Up to 2 centrifugal control units can be connected to the system at a time. The
centrifugal pump can be controlled from the Central Control Monitor or from controls
on the centrifugal control unit.
