4 .5 TE MPER AT U RE PR OB E
The temperature probe of the infusion group
permits to the control unit to know the cur-
rent temperature of the group.
Typical values of the temperature probe
are approximately 1,1 kOhm at 25°C (room
temperature) and approximately 1.4 kOhm
at 90°C.
E1 PRIMA software can detect possible mal-
functions of the temperature probe.
If alarms A4 or A5 (probes errors) are
shown on the group display, this tempera-
ture probe could be involved.
Possible solutions are:
Check the probe cable and its connec-
1
tion to the control unit.
Replace the probe.

For further information on the temper-
ature probe errors, refer to Chapter 10.
