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 / MAINTENANCE
6.2 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 batteries.
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.
