Alarm

Possible cause

Low alarmThe blood line has separated from the filter.The blood line has separated at the arterial or venousside of the access.The blood position of the venous needle has changed.Clotting before or in the filter.

High alarmThe venous blood line is kinked or clamped.The position of the venous needle has been changed.Clotting has occured after the venous pressuremeasurement e.g. in the blood line, in the venous dripchamber or in the needle.

The blood flow has been lower than the low alarm limitfor more than the preset time.The blood pump has been left in stop position too longdue to an alarm.The operator has left the blood pump in stop positiontoo long.

The stroke volume during SN is lower than the set lowalarm limit.

Low alarmThe machine has not yet stabilized the temperatureafter an interruption of the water supply.

High alarmThe temperature of the incoming water is too high.The machine has not yet stabilized the temperatureafter the function check.

Possible cause

Low alarmThe concentrate container/BiCart cartridge is empty.The concentrate has not been connected.Incorrect concentrate has been connected.The proper concentrate has not been selected on thedisplay.There is an interruption in the concentrate administra-tion to the machine e.g. the connector is not properlyconnected to the pick-up tube, the concentrate line iskinked or occluded.Air is drawn into the machine instead of concentrate.The filter(s) of the concentrate(s) is/are clogged.The content of the concentrate container does notcorrespond to the specifications given.

High alarmIncorrect concentrate has been connected.The proper concentrate has not been selected on thedisplay.The content of the concentrate container does notcorrespond to the specifications given.

Low alarmThe position of the arterial needle has been changed.The arterial blood line is kinked or clotted between thearterial access and the arterial pressure measurement.The set blood flow rate exceeds the blood flow that thearterial access has possibility to deliver.The position of the arterial needle has changed.

High alarmThe blood line has separated at the arterial side of theaccess.The position of the arterial needle has changed.Air or infusion enters the arterial line between thearterial access and the blood pump e.g. when a preblood pump infusion is connected.

Alarm

Possible cause

Low alarmThe set value for the treatment time has beenincreased or the set value for the UF volume has beendecreased during treatment.Venous pressure decreases during treatment.

High alarmThe set value for the treatment time has been decrea-sed or the set value for the UF volume has beenincreased.Venous pressure increases during treatment.Partly clogged dialyzer.

The connection to the external computer system hasbeen interrupted.

No UF volume has been set when the machine detectsblood

Calculated set UF rate is lower than minimum UFrate set value.

Blood line(s) not properly connected to e.g. the arte-rial needle connection, the filter connection(s), theinfusion port(s).Blood line(s) or the filter not properly de-aired duringpriming.An empty infusion container with air inlet is con-nected to the blood line(s).The arterial needle is dislocated.

Possible cause

The position of the arterial needle has been changed.The arterial blood line is kinked or clotted between thearterial access and the arterial pressure measurement.The set blood flow rate exceeds the blood flow that thearterial access has possibility to deliverThe position of the arterial needle has changed.

The content of the concentrate container does notcorrespond to the specifications given.Incorrect concentrate has been connected.Either the acid container or the bicarbonate container/BiCart cartridge has been emptied during bicarbonatetreatment.

A leakage, which allows blood to flow from the bloodcompartment to the dialysis fluid compartment, hasoccured.Air bubbles or particles, which can cause a false bloodleak alarm, have entered the blood leak detector.

The heparin rate has been set to zero when the machinedetects blood.

Treatment time has expired.
