5. Switch on the device.
6. Import the GSD file via the configuration program.
7. During the integration phase, select the module according to the number of channels
installed on the device.

WARNING
Incorrect connection, incorrect supply voltage
Safety risks for staff and device malfunctions
‣
Check that all connections have been established correctly in accordance with the
wiring diagram.
‣
Ensure that the supply voltage matches the voltage indicated on the nameplate.
‣
Before commissioning, check whether the correct fuse is installed for the specific
voltage range.
The analyzer is fitted with a fuse, T 1.25 A, for the 215 to 240 V AC voltage level. If
the analyzer is operated with 100 to 130 V AC, replace the fuse with the T 2.5 A fuse
supplied. The fuse is located in the cover of the electronics unit.
8.4 Switching on the measuring device
‣
Switch on the analyzer at the mains switch.
8.5 Configuring the measuring device
The following steps must be performed once the analyzer has been switched on:
1. Wait for a run-in period of 4 hours.
2. Calibration of the electrodes
3. Configure the basic parameters
4. Repeat calibration of the electrodes (after at least 12 hours)
8.5.1 Calibrating the electrodes
1. Calibrate the pH electrode →  53.
2. Calibrate the sodium electrode →  54.
Occasionally a calibration error can occur when calibrating for the first time after
commissioning. This is caused by impurities that entered during transportation, mounting
and commissioning.
3. Repeat calibration of the electrodes after the analyzer has been in operation for at
least 12 hours. This is necessary to purge the entire system after transportation and
installation.
8.5.2 Configuring the basic parameters
1. Switch to automatic mode after calibrating the electrodes:
2. In the
Maintenance menu, select the Operating Mode submenu and confirm with
.
3. Enter the factory password 1111, or a new password that has been assigned and
confirm with .
