3.10 Commissioning

Before starting the system, carry out the system check using the following
checklist. Always carry out the check:
 before the initial commissioning
 before any further commissioning if the system has been previously extended
or modified.
Start checklist:
1 Are all components correctly connected with each other (see
section 3.5, if necessary, section 3.6)?
2 Is the universal transmitter correctly connected to the power
supply (see section 3.8)?
3 Do the line voltage and line frequency agree with the data on
the name plate of the universal transmitter?
4 Is the sensor ready for measuring, e.g. a D.O. sensor filled
with electrolyte solution?
Switch on the power supply of the DIQ/S 28X. As soon as the system is suc-
cessfully initialized, the measured value display appears. With a sensor not yet
providing any measurement values, "Init" appears temporarily:
Select your system language during the first system start. The
selected system language can be changed in the Einstellungen/
Settings menu at any time.
