5.3 Warning and error messages
Warning messages and error messages inform you of potentially critical operating states. EPP9022 signals
warning messages and error messages in two ways:
• Process image [
}
14]
• LEDs [ } 34]
There are two categories of messages:
• A warning message is output if a measured value (current, voltage) is borderline. However, continuous
operation is still possible under unchanged conditions.
• An error message is output if continuous operation under unchanged conditions could lead to a defect
or to the tripping of a safety device.
The following diagrams show the threshold values for warning messages and error messages in the factory
setting.
