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
• LEDs

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.
