Centrifugal Control Unit

Circuit and clinical parameters, including setpoint value and pump flow rate, should
be stabilized in Continuous mode and be within normal operating ranges before
initiating Servo mode.
To Initiate Servo Mode:
1. Touch the Pump icon to open the Pump tab.
2. Open the
Servo
subtab.
3. Select the source pressure or flow.
4. Touch the
Auto
button.
The pump control panel displays the Servo mode symbol next to the current Servo
setpoint value. The control unit secondary display shows the current setpoint value.
The pump will respond to all safety connections including alerts or alarms that have
been established for the servo control source while operating in Servo mode.
To change setpoint:
To change the servo setpoint, turn the centrifugal control unit pump speed control
knob or adjust the pump control slide bar to increase/decrease the pump speed.
When the knob or slide bar adjustment stops, the pump locks onto the current
average value of the servo source as the new servo setpoint.
To End Servo Mode:
Use one of the following options:
•
Press the
Manual
button on the control panel and the pump will transition to
Continuous mode at its current speed. The message “MANUAL: MONITOR
FLOW” appears in the control panel message area.
• Open the
Servo
subtab within the
Pump
tab on the CCM, touch the
Manual
button, and the pump will transition to Continuous mode at its current speed.
Note:
If the centrifugal pump stops or goes to Coast speed, this will also end Servo
mode.
