6 Check that the measured resistance value matches the
resistance determined through the measured temperature
(earlier step in the procedure). E.g. R1T thermistor:
▪ Measured temperature with contact thermometer: 23.1°C,
▪ Resistance value determined through temperature (using the
table for type 1 thermistors):
Resistance at 23°C: 21.85 kΩ,
Resistance at 24°C: 20.90 kΩ,
▪ Disconnect connector and measure resistance between S90
pin 1‑2:
Measured resistance: 21.86 kΩ,
▪ Measured resistance value is inside the range. R1T
thermistor passes the check.
INFORMATION
All thermistors have a resistance tolerance of 5%.
INFORMATION
The user interface allows to monitor most thermistors.
If the measured resistance value matches the resistance
determined through the measured temperature, but the
temperature for the corresponding thermistor is NOT
correct on the user interface display, replace the applicable
PCB.
Does the measured resistance Action
of the thermistor match with
the temperature determined
resistance?
Yes Thermistor is OK. Return to the
troubleshooting of the specific
error and continue with the next
procedure.
No Replace the specific thermistor,
see
page 50.
Repair procedures
To remove the thermistor
Prerequisite: Turn OFF the unit via the user interface.
Prerequisite: Turn OFF the respective circuit breaker.
Prerequisite: Remove the required plate work, see
work" on page 40.
1 Locate the thermistor that needs to be removed.
2 Cut the tie straps that fix the insulation and the thermistor wire.
