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 sc1000 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 problem 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.
