3.11 Commissioning
Start checklist and
system start
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.
Starting the system Switch on the voltage supply of the DIQ/S 182 XT-4 and all additional
power supply modules. As soon as the system is successfully
initialized, the measured value display appears. In the case of
IQ sensors that are not yet providing measured values, "Init" appears
temporarily

Start checklist
1 Are all system components correctly connected with one
another (see section 3.5)?
2 Are the DIQ/S 182 XT-4 and all additional power supply
modules correctly connected to the voltage supply (see
section 3.9)?
3 Do the line voltage and line frequency agree with the data on
the name plate of theDIQ/S 182 XT-4 and all additional power
supply modules?
4 Are all IQ sensors ready for measuring, e.g. a D.O. sensor
filled with electrolyte solution?
Assign a name to each IQ sensor after putting it into
operation for the first time so you can identify it more easily.
How to assign a sensor name is described in section 5.3 on
page 5-2.
If the system start failed, see chapter 8 W
