Figure 8 - Detail of the pair of electrodes assembly
The protection caps of the electrodes’ sensitive membrane should be stored in a safe place as it will help keep its
moisture if the water sampling station must be turned off for an extended period.
A similar assembly procedure applies to the electrode to measure the temperature (not included), which can be
installed in the relative seat of the probe holder by replacing the cap with the supplied fitting.
Electrical connection
Electrical installation must be carried out in accordance with the standards in force in the country of use. If the
power cables do not have a plug, the device must be connected to the mains via an interposed omnipolar cut-out
switch with minimum distance between contacts of at least 3 mm. Before accessing each powered device,
make sure the mains power supply has been disconnected (Figure 9).
Figure 9 – Electrical connection – inputs 1 and 2
The control panel is supplied already wired internally.
It is advisable to power the control station separately from other devices that may cause interference.
For example, heavy inductive loads (recirculation pumps) or frequency driven device (inverters).
Downtime
Sequence of steps to carry out before long periods of downtime:
•
Turn off both tool pumps
•
Close the input and output valves to the measuring cell
•
Make sure the electrodes are immersed in a sufficient amount of water, otherwise loosen the ring
nuts, remove them and leave them to soak in water or preferably in a KCL preservation solution.
