3.2 Checking the Temperature Sensors
Introduction If the cause of the problem is related to the temperature sensors, the sensors should be checked prior
to changing the PCB or an output device.
Temperature
sensors
The following sensors of the EUWA*5-24KBZW1 and EUWY*5-24KBZW1 are connected to the I/O
PCB: R3T/ R4T and R6T/R7T/R8T.
How to check To check the temperature sensors, proceed as follows:
Step Action
1 Disconnect the sensor from the I/O PCB for EUWA*5-24KBZW1 and
EUWY*5-24KBZW1.
2 Measure the temperature and the resistance value.
3 Check whether the measured values correspond with the values in the appropriate table:
"I/O PCB sensors: R3T and R4T for EUWA*5-24KBZW1 and EUWY*5-24KBZW1" on
page 3–15.
