Bit 5. Overload
(1 Bit, Default = 0 / off)
Signalizes that the configured range got exceeded since set-
ting the corresponding channel active and stays high un-
til the next reset-cycle. Internal hard integrator (capacitor)
overload will set Overload + Error until reset cycle.
Bit 6. Warning
(1 Bit, Default = 0 / off)
Warning bit set active indicates violation of discharge time
(handshake ignored) or if cycle time of communication in-
terface is set too fast.
Bit 7. Error
(1 Bit, Default = 0 / off)
Wrong/missing device calibration, or invalid data, or hard-
ware overload, or other critical failure (details are available
using the error code)
Description
Discharge time of Charge
amplifier capacity was not
kept
The sync sampling rate
exceeds internal processing
capacity
Internal CPU core tempera-
ture exceeds predefined
level
Warning
Class Possible reason
Warning - Duration of Piezo-Reset too
short to unload charge integrator
Solution: Use Status Bits as
reference for successful status
changes
Warning - Cycle time of fieldbus too fast
- Too many measurement data
- Acyclic fieldbus requests
Solution: choose longer cycle
time or reduce measurement data
Warning - Ambient temperature too high
Solution: reduce ambient tem-
perature or mount device for
passive cooling
Medium - Internal Watchdog fired
