4.5.1.3 Electrode connections
W A R N I N G
To conform with security standards and to respect the EMC compliancy of the analyzer, this procedure must be followed when connecting selective, reference, combined and temperature electrodes to the electronic unit of the analyzer.
Before being connected to the terminal block of the measurement board, electrode cables must pass through ferrite blocks to minimize the risk of outside interferences that could cause erroneous measurement data.
For the selective or combined electrode, install the cable gland and pass the cable of into the electronic unit in the same way as for all other cables (as described in Connecting
peripherals on page 14). Once both wires (measurement and shield) are in place, pass
them both through the ferrite block. Make a loop by passing them through a second time before connecting them to their respective inputs as illustrated in Figure 5.
Figure 5 Selective or combined electrode connection
For the reference electrode (not applicable in the case of a combined electrode) and the temperature sensor, install the cable glands and pass the cables into the electronic unit in the same way as for all other cables (as described in Connecting peripherals on page 14). Once the reference electrode wire and the two temperature sensor wires are in place, pass them all through the second ferrite block. Make a loop by passing them through a second time before connecting them to their respective inputs as illustrated in
Figure 6 (the temperature sensor has no polarity).

Section 7 Maintenance and Troubleshooting
7.1 Maintenance
D A N G E R
Electrocution hazard. Always make sure the analyzer is turned off and power is disconnected before carrying out any maintenance on the analyzer.
7.1.1 General
For periodic maintenance, all the elements are freely accessible on the front panel.
For installation of accessories and specialized service work the analyzer is easily accessible from all sides with some simple manipulations. The electronic control and analytical units can be accessed and removed after opening the front of the analyzer with the special key provided.
7.1.2 Maintenance schedule
The schedule is dependent on the type of application. In general we can say that a monthly maintenance is required to perform the following tasks:
• Check all reagent and chemical containers. Refill if necessary
• Disconnect the tubing and replace the other way round
• Every 2 months replace all the tubing
• Check the measurement chamber and electrodes for any deposits. Clean if visibly
contaminated
• Check all tube connections for any leaks
• Check the system is running smoothly. Calibrate if necessary
7.1.3 Software upgrade
D A N G E R
Electrocution hazard. Always make sure the analyzer is turned off and power is disconnected before upgrading the software.
If a new software version is made available it should be installed as follows:
1. Open the electronic unit from the rear and disconnect the data cable from terminal
J1 on the measurement board.
2. Unscrew the three screws on the metal shielding plate (on which the measurement
board is attached) and lift out. Do not remove the measurement board from the shielding plate.
3. Remove the old EEPROM (referenced 8810 ISE XXX.X) from position IC19.
4. Install the new EEPROM with the latest software in the same position IC19.
5. Replace the metal shielding plate and screw back the three screws.
6. Reconnect the data cable to terminal J1 on the measurement board.
7. Close the electron unit.
8. Reconnect power to the analyzer.
9. Switch the analyzer on using the red switch on the front, while simultaneously
pressing on the Select and Enter keys to load the new software with default values.
10. Program the analyzer with the your parameters noted on User configuration
on page 53 to reflect your user configuration.

8.8.1 Peristaltic pump
D A N G E R
Electrocution hazard. Always make sure the analyzer is turned off and power is disconnected before installing this option.
The peristaltic pump is a compact tubular pump with a constant output. The flow rate is determined by the diameter of the tube being used (see Table 8). It is constructed in a manner that ensures a constant and accurate flow rate, ideal for tasks requiring an accurate dosing of reagent.
Cassette
The Delrin® cassette can be easily raised and adapted to the size of the tubing. The bottom is equipped with 2 lateral ridges to prevent any excessive crushing of the pump tubes. The cassette is not resistant to acids or high concentration reagents. In the event of leakage, remove and rinse thoroughly with water.
Figure 17 Peristaltic pump cassette
Tubing
The Tygon® tubing has been specially designed for use with this cassette. The smaller diameter tubes have fittings on the ends for easy connection to larger tubes. The tubing is supplied with 3 fixations in order to secure the tubing in the cassette and prevent it from twisting. The tube diameter is color coded:
Table 8 Clamp tubing sizes
Color code Interior diameter (mm) Flow rate (mL/minute)
Grey-Grey 1.3 1.90
Green-Green 1.85 3.80
Violet-Violet 2.06 4.40
