Temp Sensors
unmatched
When the temperature trim function
needs to change DAC by > 1
C, the
pre and post sensors are verified
against one another. This message

are more than 0.5
C different.
Warning
Press
RESET
key to reset alarm
The temperature trim function will be disabled until the machine is
turned off and back on.
Temp Control not
calibrated
This message is displayed on the sign
on screen if the temperature sensors

verified against one another.
Advisory
Calibrate the temperature control.
Temperature greater than
max. value
Entered Temperature value is higher
than allowed.
Dialog
Message
The temperature will be set to the highest allowed level. Press
CONFIRM
to clear message and accept the maximum allowed value.
Verify that the value is acceptable.
Temperature has been
set to min.

put into bypass to verify the
temperature sensor. The OLC test
cannot be run at this time
Advisory
Wait 10 minutes and start the OLC test again.
TMP is High (toward 500) The TMP has exceeded the TMP high
alarm limit value.
Blood
Alarm
1) Check the dialyzer supply and return lines for kinks and that the
connectors are properly connected to the dialyzer or the shunt.
2) Clean the dialysate line filter screen.
3) Press
RESET
key to reset alarm. Press the
Override
key and
hold for one second to select new alarm limits or for adjusting the
TMP. If unable to reset the alarm, call your local qualified service
technician.
High UF Goal and low dialyzer KUF coefficient can exceed the
maximum TMP of 520 mmHg. The UF Goal may need to be lowered.
This in turn will lower the UF rate and the TMP. Notify a physician if
the UF Goal has changed.
Warning!
A rising TMP
may indicate a leak in the
balancing system and
should be investigated.
