5.1.7 Outputs
The measured data is available at the spring terminals as 0 - 10 V and 4 - 20 mA or as 0 - 5 V
and 0 - 20 mA signals (see chapter 5.1.5 Select the Output Signal with S8).
Additionally, the analogue outputs indicate measurement out of range as follows.
Indication of
∆ p < -5 % of measuring range and of negative difference pressure due to inverted pressure
connection.

5.2 Digital Version
The digital version is intended to be configured with PCS10 Product Configuration Software and the
USB configuration adapter (code HA011066). The device address can be overruled by setting the DIP
switches (see chapter 5.2.1 RS485 Digital Interface Settings).
Settings that can be changed with the PCS10:
ƒ
Digital communication parameters
ƒ
Application settings (see chapter 5.4.1 Application Settings)
ƒ
Display visualisation (see chapter 5.3.2 Analogue Version with PCS Settings or Digital Version)
ƒ
Auto-zero on/off and interval (see chapter 6.3.4 Auto-zero (Optional))
ƒ

Hardware Bus Termination
The bus termination can be realised enabling the slide switch on board (120 Ω resistor). Factory setting
disabled (see Fig. 1 Design and components, digital version J3).

Address setting via software
All DIP switches at position 0 → address has to be set via software (via PCS10
Product Configuration Software or via protocol BACnet / Modbus).
Default address 43.
Example: Address is set via Configuration Software.

Address setting via DIP switch
Setting the DIP switches to any other address than 0, overrules the default
address (43) or the address set via software.
Example: Address set to 3 (0000 0011 binary).
