TROUBLESHOOTING / MAINTENANCE
6.1
Replacing Sensing Probes
If a sensing probe is damaged (e.g. mechanically damaged,...), the user can replace the probe with
a new one without any adjustment of the transmitter. This way an elaborate process of returning the
equipment to the factory will be avoided.
Procedure to replace a sensing probe:
1. Remove the faulty sensing probe.
2. Connect the new replacement probe.
3. In addition, the webserver of the base station EE242 offers the possibility to manage the sensing
probes (see chapter Configuration software).

Troubleshooting
Error
• possible cause → Action / Correction
Sensing probe measures incorrectly
• Error during recalibration of the transmitter → Reset to default factory settings and repeat the
calibration procedure.
• Filter cap dirty → Replace filter cap
• Sensor faulty → Replace sensing probe
Long response time
• Filter cap dirty → Replace filter cap
• Wrong filter cap → Replace with suitable filter cap for the application.
Transmitter failure
• Interrupted power supply or weak batteries → Check the wiring of the power supply resp. test the bat-
teries. If the batteries are replaced within 7 days after the failure, the system will automatically restart.
If the batteries are replaced after 7 days, it suffices to press the push-button "Connect" at the base
station to restore the connection.
Too high humidity value
• Condensation at the tip of probe → Dry out the probe tip and check if the probe is mounted in the
correct way.
• Wrong filter cap → Replace with suitable filter cap for the application.
Failure of the wireless connection
• Interrupted power supply or weak batteries → Check the wiring of the power supply resp. test the
batteries.
• New erected obstacles (metal structures ...) attenuate the wireless signal → Bypass the obstacles
utilizing additional router(s).
Forgot password
• → Reset the base station E242 to the default factory settings (IP- address, Password,.) see chapter
3.1.5. Network Reset.
