8.2 User warnings
The Micromatic equipment carries out constant monitoring of various operating parameters and alerts the user via acoustic signals
and activation of the corresponding icon:
•
Pretreatment changes: When the equipment exceeds the number of operating hours assigned to the pretreatment this warning
is activated, indicating that the cartridges must be changed [1] and [2].
•
Deionisation resin change: This warning is activated when the equipment detects that the Type II Water conductivity is higher
than the set value. By default, a maximum of 10 µS/cm is set. The user can select a different value (between 1 and 20 µS/cm).
•
Water cut off: An icon is activated indicating that water has stopped entering the equipment.
•
Conductivity probe: Notify the technical service Conductivity probe does not measure correctly.
8.3 Entering parameters (set-up menu)
The system allows the user to set values for:
- Water temperature
- Conductivity for Type II Water
- Pretreatment change
Press MODE/ESC
to access the set-up menu.
The screen displays the following values in sequence (by pressing the keys and )
Parameter
Value
uS Value

To modify the set values, take the following steps:
a.
Select the parameter (for example Value uS)
b. ENTER = The first digit blinks. To modify it press until the desired value is shown. To accept, press ENTER.
c.
The second digit blinks. Perform the same operation.
d.
The third digit blinks. Perform the same operation and the value will be set.
e.
To exit the set-up menu = ESC.
8.3.1 Set value for deionisation resin change
The equipment is delivered with a set value of 10 µS/cm: When the Type II Water reaches or exceeds the conductivity value, the
warning to change the deionisation resin cartridges [3] and [4] is activated.
The user can select a different set value (between 1 and 20 µS/cm) to activate this warning.
8.3.2 Water temperature
The conductivity values displayed on the screen are compensated at 25°C.
The conductivity value depends on the water temperature and is usually expressed by normalising the reading to 25°C. To this
end, the water temperature at which measurement is performed must be taken into account and a correction factor of 2% applied
for each degree of temperature deviation from the reference temperature:
