6.2.5. Module Status Indication
If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type FLOAT32) or to
0x8000 (INT16). It is possible to read out the module status information via Modbus register 610 (0x261). Status
indicarion is bit-coded. If an event is present, the corresponding bit is set to 1.
Measured values outside the measuring range are limited with the corresponding limit value.
Error Bits Description Recommended action
Bit 0 Display communication error Return the unit to the E+E Customer Service
Bit 1 Ext. module communication error (AM1,
AM2, J4)
Return the unit to the E+E Customer Service

6.2.6. Device Operating Conditions Indication
If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type FLOAT32) or
to 0x8000 (INT16). It is possible to retrieve device operating conditions information from Modbus register 611
(0x262). Errors are displayed in bit-coded form. If an event is present, the corresponding bit is set to 1.
Measured values outside the measuring range are limited with the corresponding limit value.
Event Bits Description Recommended action
Bit 0 PCB temperature too low Check temperature at installation point
Bit 1 PCB temperature too high Check temperature at installation point
Bit 2 T value too low Check process temperature
Bit 3 T value too high Check process temperature
Bit 4 PT1000 value too low (T17 and T28 only) Check process temperature
Bit 5 PT1000 value too high (T17 and T28 only) Check process temperature
Bit 6 RH sensor too dry Check process humidity
Bit 7 RH sensor condensation Check process humidity
