3.3. Cell cables
Compensation of the cable length
To minimize the effect of the cable resistance in a conductivity measurement, the cable length is compensa-
ted by the 4-wire system. With the Pt 1000 temperature sensor, the cable resistance has little importance.
However, in order to reduce the resistance of the conductor to a half, 2 cables have been connected to
the ends of the sensor.

tion (terminal 1).
• Connect the ground only when there could
be interference problems.

3.4. Protective wiring of switching contacts
Relay contacts are subjected to electrical erosion.
Especially with inductive and capacitive loads, the service life of the contacts will be reduced.
For suppression of sparks and arcing, components such as RC combinations, nonlinear resistors, series
resistors and diodes should be used.
Important note:
Fit a jumper between terminals 9 and 10 (12 and 13 in panel mount instrument) and another between
the terminals 11 and 12 (10 and 11 in panel mount instrument).

4. Operation
4.1. Description
Display
si628 C have an alphanumeric display that explains itself. One of the most significant screens is des-
cribed below as an example:
The instrument is already measuring conductivity,
with the following configuration:
• Temperature coefficient, CT, fixed at 2% / °C.
• Cell constant C=1 cm-1.
• Reference temperature, RT, fixed at 25°C.
• Limit relay is activated at 1000 µS/cm, and
desactivated at 800 µS/cm.
• Alarm relay is activated after 1minute with the
reading out of limit.
• Output current 4 mA = 200 µS/cm, 20 mA =
2000 µS/cm.
To modify the default configuration (except from
the temperature Coefficient and the reference tem-
perature) see page 16.
4.2. Setting up
Connect the si628 C to mains. At power up the first time only the following screens will appear:
