Test the Alarms and Alerts Every Three Months
The following checks and tests should be performed periodically.
Every Three Months. . . Test Your Alarms and Alerts
Pressure Limit Alerts and Set an alert and alarm. Apply a pressure (slightly above alert
Alarms value) to the pressure transducer. Check that the audible
alert sounds, a message is displayed on CCM, the appropriate
icon on the CCM flashes yellow, and the status LED on the
appropriate module flashes yellow. Check that a message is
displayed on all pumps with a safety connection to the
pressure transducer.
Increase the pressure as necessary. Check that the audible alarm
sounds, a message is displayed on CCM, the appropriate icon on the
CCM flashes red, and the status LED on the appropriate
module flashes red. Check that a message is displayed on all pumps
with a safety connection to the pressure transducer.
Roller Pump Overspeed and Start the pump, insert the hand crank, and set the speed to 15 RPMs.
Pump Jam
Begin hand cranking rapidly for at least 5 revolutions. Check that the
pump changes to Stop mode and “< Pump Name >: Overspeed”
appears on the Central Control Monitor message display and “STOP:
OVERSPEED” appears on the pump control panel.
Insert tubing in the pump raceway and start the pump heads
rotating. Turn the occlusion knob counterclockwise to overocclude.
Check that the pump switches to Stop mode and “< Pump Name >:
Pump Jam” appears on the Central Control Monitor message display
and “STOP: PUMP JAM” appears on the pump control panel.
Temperature Alarm Check that the audible alarm sounds and that the alarm message
appears on the CCM when the temperature probes are inserted in
water warmer than the alarm limit. Check each probe.
Flow alarm and alerts for Test the flow alarms associated with centrifugal pumps and
Centrifugal Pump. flowmeter modules. Set up an unrestricted test circuit using
priming solution. Set the minimum flow alarm setting at 0.1 L/min.
Verify the alarms as follows:
To check the backflow alarm, adjust the flow to 1.0 L/min. Reposition
the flow sensor so that the arrow is pointing in the opposite
direction of circuit flow. The backflow alarm should activate,
displaying “<Flow Name>: BACKFLOW” on the CCM and sounding a
dual tone audible alarm. Any pumps with a safety connection to the
flow sensor should display “<Response>: BACKFLOW” on the pump
display. Reposition the flow sensor so that the arrow is pointing in
the direction of flow.
Ensure that the speed is above 1550 RPM and the flow is above the
minimum flow alarm setpoint. Clamp the outlet line. The minimum
flow alarm should activate, displaying “<Pump Name>: MINIMUM
FLOW” on the CCM, sounding the dual tone alarm, and displaying
“MINIMUM FLOW” on the control unit display.
Note: The minimum flow alarm is only enabled when the flowmeter
module is linked to the centrifugal pump by placing the flow sensor
on the primary display area of the Centrifugal Pump icon during
configuration.
