7.1 Installation check
Monitor all connections making sure they are tight. In order to guarantee fault free
operation the terminal screws must be tight onto the connection cables. The unit is
now ready for operation.
7.2 Commissioning
Once the power supply has been connected the head transmitter is operational.
Setting up using the PC configuration software
The head transmitter left the factory with a default parameter configuration. If no
customer specific configuration was mentioned on the order then the default
parameter configuration is constructed as follows:
Sensor
Connection mode
Measurement range and
units
Hint:
If a change has been made to the measurement point then the head transmitter can
be re-configured. In order to re-configure the parameters follow these instructions:
• Install the configuration software and make connection to the PC (see Chap. 6,
Operation).
• For detailed operating instructions for the PC configuration software please read the
online documentation contained in the PC configuration software.
Interactive setting up of the temperature transmitter
Customer specific linearisation and sensor matching is done using the SMC32.exe
(Sensor Matching Calibration) configuration software. The SMC32.exe programme
calculates the linearisation coefficients X0 to X4, that need to be entered into the PC
configuration software.
