Troubleshooting and repair

General problems

Problem	Cause/solution
Device does not respond (status LED always off).	Check the cable connections (see Connecting the sensors, actuators and power supply) The capacity of the energy store in the power supply unit is depleted.
Communication problems	Load the device log from the 4-Channel Data Logger using the DeviceConfig (see "Log" tab). A list of all the possible error codes is included in the chapter "Log entries and error codes" (see Log entries and error codes). The capacity of the energy store in the power supply unit is virtually depleted.
The connection via the external SIM card is not working.	The chargeable feature "Activation code VPN SIM (300539)" has not been released. Check whether the external SIM card has been inserted correctly (see Inserting/replacing the SIM card). Check whether the configuration data (PIN, APN, username and password) have been set correctly via the DeviceConfig (see "GSM" tab). Check whether the PIN code (if required by the SIM card) has been set correctly by the DeviceConfig .
Not all or no data is available on the server.	The connection was aborted during the transmission, which is indicated by a time-out entry in the connection list (see "myDatanet Server Manual " 805002). Solution: Initiate a transmission or wait for the next cyclical transfer. The assignment of the device and site is not correct (see Site).
Data at universal input is not plausible.	Check the cable connections (see Connecting the sensors, actuators and power supply) Check whether the output signal from the sensor that you are using is compatible with the electrical characteristics of the universal inputs (see Technical details about the universal inputs). Check whether the universal input configuration matches the sensor output signal (see Measurement channels). Check the filter settings of the universal input (see Measurement channels). Check whether the Ext. warmup time has been selected for the sensor that you are using.
The measurement values of the external temperature sensor are not plausible.	The chargeable feature "Activation code temperature input (300542)" has not been released. Check the cable connections (see Connecting the sensors, actuators and power supply)
The alarm state of a measurement channel was not identified.	Increase the measurement cycle
The alarm state was not transmitted although the data is present.	Check the alarm settings of the measurement channel The connection was aborted during the transmission, which is indicated by a time-out entry in the connection list (see "myDatanet Server Manual " 805002). Solution: Initiate an Aloha transmission or wait for the next cyclical transmission.
The alarm message was not sent although the alarm was signalled.	Check the settings of the alarm schedule (see "myDatanet Server Manual " 805002) Check the address data of the alarm schedule (see "myDatanet Server Manual " 805002)
Isolated switch contact is not working.	Disruption to the voltage that is conducted via the relays
