5.2.7 Device 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 all status and error information via Modbus
register 602 (0x259). 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.
Error Bits Description Recommended action
Bit 0 Error: Sensor not adjusted
1. Carry out zero point adjustment
2. Return to factory adjustment
2. Return the faulty unit to E+E for service
Bit 1 Error: Pressure measurement faulty
1. Check the installation and clean the device
2. Carry out zero point adjustment
3. Return the faulty unit to E+E for service
Bit 2 Error: Faulty display communication 1. Check the display connection
Bit 3 Error: Auto-zero did not work
1. Carry out zero point adjustment
2. Return the faulty unit to E+E for service

5.3.1 Analogue Version with DIP Switch Settings
See chapter 5.1 Analogue Version for the configuration options.
5.3.2 Analogue Version with PCS Settings or Digital Version
The factory setting of the display (if present) shows the measured differential pressure in Pascal [Pa].
With the PCS10 Product Configuration Software and the optional USB configuration adapter HA011066,
the user can change the display layout and the visualised parameter according the selected application:
