Troubleshooting
If entries are only implemented with a delay or are not accepted for a short time, the delay
may be caused by a busy data network. Refer to the troubleshooting section in the sc1500
User Manual.
If, in normal operation, problems occur that are apparently caused by the controller, restart
the system.
After a software update, a system expansion or after an interruption in the power supply, it
may be necessary to set the system parameters again.
Note all the values that are changed or entered so all the necessary data can be used to
configure the parameters again.
1. Save all important data.
2. Isolate the supply of power and wait for 5 seconds.
3. Reapply power to the controller.
4. Check all relevant settings.
5. If the problems still occurs, contact Technical Support.
If the complete analysis instrument is not working, check whether the humidity sensor has
tripped. Fix the damage, dry the humidity sensor and restart the system.
If the problems still occurs, contact Technical Support.
