Troubleshooting
If entries are 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
controller documentation.
After a software update, a system expansion or an interruption in the power supply, it may
be necessary to set the controller settings again. Record all the settings values that are
changed or entered so all the necessary data can be used to configure the parameters
again.
If, in usual operation, problems occur that are apparently caused by the controller, reboot
the controller as follows:
1. Save all important data that is on the SC Controller.
2. Remove power from the controller. Wait 5 seconds.
3. Supply power to the controller.
4. Make sure that all of the applicable settings are correct.
5. If the problems continue, contact technical support.
If the analyzer operation is not correct, identify if the humidity sensor has tripped. Repair
the damage, dry the humidity sensor and restart the system. If the problem continues,
contact technical support.
The analyzer has a status indicator light that shows different analyzer conditions, errors
and warnings. Refer to Status indicator light
