Edit Safety Connections
A safety connection is a communications link set up between two system components
that allows a device to receive information from another device or module. Safety
connections allow the user to set up pump responses to events generated by air
sensors, level sensors, pressure sensors, flow sensors, roller pumps, and centrifugal
pumps. Safety connections allow the user to set up occluder responses to primary
pump events. Safety connections cannot be set up for follower roller pumps.
For example, a safety connection between an air detector and a roller pump allows
the user to set the roller pump to stop in the case of an air detected alarm. It also
allows the event message to display on the pump or centrifugal control unit local
display.
Servo mode capability is also set up in the safety connections area. A pump can use
data from a pressure or flow sensor to regulate its speed to maintain pressure or flow.
The events generated by the various devices and response choices that can be
made for the occluder, roller pumps, and centrifugal control units are outlined in the
Connection Matrix, found at the end of this section. Note that some pump responses
are also events.
Prior to setting up safety connections, study the Connection Matrix and prepare a
list of the responding devices in the circuit and the events the user would like these
devices to respond to.
Roller pumps and centrifugal pumps can respond to events from the following
devices, up to a maximum of 7 devices and 16 responses.
Maximum number of connections to one pump
Level Detectors 1
Air Detectors 4
Pressure Sensors 4
Flow Sensors 1
Roller Pumps 5
Centrifugal Pumps 1
It is recommended that safety connections be established directly between individual
devices and pumps to achieve the desired system response.
If using air detection, a safety connection to the primary pump is required. The pump
response for the safety connection must not be No response.
If using level and/or pressure detection, Alarm and Alert safety connections from
each to the primary pump is required. The pump response for the safety connections
must not be No response.
A second pump can be designated as the backup pump. All the primary pump
settings can be reassigned to the backup pump if needed. See
Perfusion Screen
System tab , Reassign Module subtab section for more details.
