8 English

An aluminium shielding plate inside the transmitter gives a detailed description of the different
terminals and their connections to external elements:
Figure 2 Electronic board layout
1 Terminal block 4-20 mA 5 Measurement module
2 Communications BUS (option) 6 Programmed EEPROM
3 CPU board 7 Software update connector
4 Relay board (option) 8 Power supply board
Electric connections are made on the terminal connectors inside the housing. Put the cables into the
appropriate openings.
• The main supply and relay cables should be fed through the openings behind the shielded plate.
To remove the plate, unscrew the fixing screw on the left side of the plate.
• When opening the transmitter be careful of any attached cables.
• Sensor and mA output cables should be fed through the openings provided on top of the plate.
• Always use shielded cables. The shielding should be connected to the central shielding earth.
5.2.1 Mains connection
WARNING
Mains power should always be cut off prior to working inside the instrument.
Electrical connections should be performed by qualified personnel. The power supply accepts
100-240 VAC ± 10% (50/60 Hz) without changes in configuration. The terminal block for power
connections can be lifted from its header for easier installation.
For safety reasons, it is essential that the following precautions for use are respected:
• Use a three wire mains supply cable (2 core + PE) with a cross-section between 0.35 and 2 mm2
(AWG 22 to 14) rated at 105°C minimum. The external cable insulation should be cut as close as
possible from the terminal block.
• The instrument should be connected to the mains by means of a circuit breaker or fuse whose
value should be inferior or equal to 20 A. It should be positioned close to the transmitter and
identified.
• This protection should cut off the phase and neutral in the event of an electrical problem or if the
user wishes to access the inside of the instrument. The protective earth connector, on the other
hand, must always be connected.
• Cabling should be specified for a minimum of 80°C (176°F).
English 9

5.3 Hydraulic connections
• Remove the flow chamber retaining nut (No. 5 in Figure 1 on page 7) and remove the flow
chamber.
• Remove the pH bulb protector and rinse the bulb area with distilled water or pH buffer. Save the
protector for any future electrode storage. If air bubbles are visible in the pH bulb, gently shake the
electrode downward in the same manner as a clinical thermometer to remove them.
• Put the flow chamber back in place and secure with the retaining nut.
• Assemble the 1/8" NPT connections in the sample inlet and outlet positions (Nos. 8 and 9
respectively in Figure 1 on page 7), then connect the sample inlet and outlet piping.
• Circulate the sample and check visually through the chamber for the absence of any air bubbles.
• Adjust the sample flow rate to about 150 mL/min.
• The flow chamber must be earthed (No. 4 in Figure 1 on page 7) grounded to protect from any
external electrical noise.
Note: To avoid any damage to the electrode ensure the flow chamber is never empty and that the glass bulb is
always immersed in water.

9.4 HISTORIC option
1. Select HISTORIC from the CALIBRATION menu. This displays the calibration date, the slope
and zero parameters of the last two calibrations. Press select to view each screen in turn.
Section 10 Maintenance
When changing or cleaning the electrode or servicing the transmitter, select the MAINTENANCE
option.
The transmitter will continue to display measurements, but the analog output value will be the value
programmed in the mA Menu (see SPECIAL PROG on page 16).
10.1 pH sensor
Mechanically intact sensors with no broken parts can often be restored to normal performance using
one of the following procedures:
•Salt deposits: Dissolve the deposit by immersing the sensor in a 0.1M HCl solution for 5 minutes,
followed by immersion in a 0.1M NaOH solution for 5 minutes. Rinse the sensor thoroughly with
distilled water.
•Oil/Grease films: Wash the sensor pH bulb in mild detergent. Rinse the sensor tip with distilled
water.
18 English

•Clogged reference junction: Heat a diluted KCl solution to 60-80°C. Place the reference portion
of the pH sensor into the heated KCl solution for approximately 10 minutes. Allow the sensor to
cool while immersed in unheated KCl solution.
If these procedures fail to restore normal sensor response, replace the sensor.
10.2 Transmitter
Every so often, clean the transmitter with a soft cloth using a mild, non-abrasive cleaning agent. Do
not use any abrasive type of cleaning agents or any abrasive cleaning materials as this will damage
the surface.
