Central Control Monitor
Set Servo Mode Connections
Roller pumps and centrifugal pumps can be configured to operate in Servo mode.
In Servo mode, the pump speed is automatically regulated to maintain a selected
pressure or flow setpoint.
To operate in Servo mode, the desired pressure or flow must be designated as a
servo control source. Safety connections may also be established between the pump
and the source pressure or flow.

Servo Control Source
To establish a pressure or flow as a Servo Control Source:
1. Create a safety connection between the pump and the desired pressure or flow
source.
2. Touch the Servo Control Source button until the button displays Yes.
3. Select pump responses to pressure or flow events, if desired.
4. Touch the OK button when all servo control sources have been designated.
Setting a cardioplegia pump to stop with the primary pump
There are instances, such as using blood cardioplegia, when it is desirable to have
the cardioplegia pump stop when the primary pump stops. After the cardioplegia
pump is placed, the user will be asked if they want to setup the cardioplegia pump to
stop with the primary pump.
If using a centrifugal primary pump the cardioplegia pump safety connection will
not be active until the centrifugal pump speed has been raised above Coast. This
supports priming the perfusion circuit at lower centrifugal pump speeds.
Choosing Yes will set the following safety connections:
