LWARNING
The device is live!
Risk of electric shock!
‣Do not connect the analyzer to the electricity supply before the installation work is
completed and the media are connected.
‣Follow the instructions in the "Electrical connection" section.
5.2.1 Mounting sequence
Bench-top mounting
1. Place the analyzer on an even, vibration-free surface.
2. Open the front door of the housing and check the interior structure for visible signs
of damage.
3. Check all the built-in fluid connections. The hoses must not be bent or damaged.
4. Check all the fluid couplings to ensure they are fitted securely (tighten by hand).

Mounting TOC Analyzer CA79

5. After the visual inspections, it is time to mount the sample feed lines and the waste
line of the TOC system. It is important to keep the lines as short as possible and,
when shortening, to cut them straight at a right angle with a hose cutter.
Mounting on a wall
1. Open the front door of the housing and check the interior structure for visible signs
of damage.
2. Check all the built-in fluid connections. The hoses must not be bent or damaged.
3. Check all the fluid couplings to ensure they are fitted securely (tighten by hand).
4. After the visual inspections, it is time to mount the sample feed lines and the waste
line of the TOC system. It is important to keep the lines as short as possible and,
when shortening, to cut them straight at a right angle with a hose cutter.
5. Mount the customer-specific mounting frame on the wall.
6. Mount the housing on the mounting frame.
Electrical connection
1. Connect the signal outputs →  10.

6.1 Connecting instructions
LWARNING
The device is live!
Risk of electric shock! The line filter, the overvoltage module and the main switch are still
connected to the power supply even when the main switch is switched off!
‣Disconnect the device from the power supply (unplug the mains plug).
‣Before connecting, ensure that the mains voltage matches the voltage indicated on the
nameplate.
‣Ensure that the analyzer is sufficiently grounded via the mains connection.
‣Before establishing the electrical connection, verify that the pre-installed power cable
meets the local national electrical safety specifications.
6.2 Connecting the analyzer
‣Plug the mains plug into the socket (240 V, 50/60 Hz or optionally 100 V, 50/60 Hz).
6.3 Ensuring the degree of protection
Only the mechanical and electrical connections which are described in these instructions
and which are necessary for the required, designated use, may be carried out on the device
delivered.
‣Exercise care when carrying out the work.
Otherwise, the individual types of protection (Ingress Protection (IP), electrical safety, EMC
interference immunity) agreed for this product can no longer be guaranteed due,
for example to covers being left off or cable (ends) that are loose or insufficiently secured.
6.4 Post-connection check
Carry out the following checks once you have made the electrical connection:
Device condition and specifications Notes
Are the cables free from damage on the outside? Visual inspection
Electrical connection Notes
Does the supply voltage of the connected transmitter match the data
on the nameplate?
240 V AC 50/60 Hz
100 V AC 50/60 Hz
Are the current outputs shielded and connected?
Are the connected cables provided with strain relief?
Are the cable types properly isolated from one another? Route the power cable and signal cables
separately from one another over the
entire route. Separate cable ducts are
ideal.
Is the cable run correct, without loops and cross-overs?
Are the power cable and signal cables connected correctly and in
accordance with the wiring diagram?

8.1 Function check
Incorrect or improperly connected hose connections cause liquid to leak and can cause
damage!
‣Check all connections and ensure they have been established correctly.
‣In particular, check all hose connections to ensure they are secure and liquid cannot
escape.
Incorrect power supply will damage the device!
‣Ensure that the supply voltage matches the voltage indicated on the nameplate.
8.2 Login procedure
An account and a password are required to log in. At the start, the Install with password
account is selected by default. This must be changed directly. The first time the operator
tries to log in, they are asked to assign a new password. More information on user
administration is provided in the →  33.
‣Enter a new password and confirm →  37.
8.3 Configuring the measuring device
8.3.1 Performing the measurement
Before initial commissioning, a rinsing process (a measurement) must be performed
for at least 30 minutes. In the event of larger impurities and contamination, rinsing
(measurement) must continue until the same values are consistently displayed.
1. Press the Measure key in the main menu.
 A pop-up window opens.
2. Press the Yes key.
 The program starts by rinsing the system in order to prepare for the TOC
measurement.
3. Set the rinse time:
Open the Settings menu and set the rinse time →  28.
4. Change the time intervals:
Select the time intervals by pressing the appropriate key below the chart.
5. Display the history:
Press the Viewer key in the main menu.
 The Viewer menu is opened and the history is displayed →  22. This does not
interrupt the measurement.
6. Interrupt the measurement:
Exit the Measure menu, e.g. by switching to the Settings menu.
Once the rinsing process is finished, the measurement is started automatically. The TOC,
conductivity and temperature values are shown on the display. The measured values are
shown in the chart on the right-hand side. If the TOC or conductivity value exceeds the
configured limit value, the value is displayed in red. In addition, a warning is output via an
analog output (optional). The limit can be shown as a red line in the chart.

 7 Measurement over range limit
Leak in the system
If there is a leak in the system, the analyzer stops the measurement automatically and
closes valve 1. Once the leak has been found and eliminated, the analyzer starts measuring
again (only if the Continue after error option is enabled in the Settings menu, Options 2
tab →  28. The leak sensor in the system must be dried thoroughly beforehand. The
leak sensor is located on the base of the device on the right-hand side.
