Functionality

'Versatronic' is a multifunctional measurement and control device. Up to four
measurements can be recorded and processed simultaneously with it. The following
describes the key aspects in more detail:
Display A 5.5" colour touchscreen displays all the parameters and lets you use and set up the device.
The plain text operating approach facilitates the operation of the unit by the user.
The factory preset languages for the user to choose from are: German, English, Spanish,
French and Italian.
Measure As a central platform for displaying and further processing pH, potential redox, electrolytic
conductivity, temperature, and disinfection readings, such as free chlorine, total chlorine,
chlorine dioxide and peracetic acid, or flow rate, this system offers an extensive range of
applications. Universal inputs can be used to measure analogue readings via unit signals [0 (4)
to 20 mA or 0 to 10 V]. Overall, the device can simultaneously measure up to 19 parameters
and manage them.
Regulate In addition to numerous simple alarms, limits, or time-controlled switching functions, you can
simultaneously define up to 4 higher-level control loops in Ecolab 'Versatronic' .
The field-tested Ecolab control algorithms for P, PI, PD and PID control are used.
Register There is an integrated screen recorder for logging data. Up to 8 analogue readings and 6
binary signals are registered and displayed on the screen in its time cycle. Storage is tamper-
proof and meets official record keeping regulations. The data can be read by Ecolab PCC
software or USB memory stick and evaluated with the PC Evaluation Software PCA3000
Ecolab.
DANGER!
The device is not suitable for use in potentially explosive
environments.
3.1.1 Special version Versatronic – Cooling Water
The special version of Versatonic – Cooling Water was specially designed for the
requirements in the cooling water desalination and can control up to three cooling towers
simultaneously.
Depending on the number of cooling towers to be controlled, two additional
measurements such as pH, ORP and chlorine measurements can also be recorded and
processed. The Versatronic – Cooling water monitors and controls each cooling tower in
respect to the following criteria:
Desalination
If the measured conductivity value exceeds the target value W +, the output terminal
for the desalination valve is activated, and "Bleeding" is displayed.
As soon as the conductivity value drops below W-, due to fresh water supply, the desalination valve is closed
and the display message disappears.
Biocide dosing is locked for the duration of the desalination.
Biocide dosing
When controlling one or two cooling towers with one device, two different biocides can be dosed; when
controlling three cooling towers, you can dose one biocide per cooling tower.
The dosing points are determined by a week timer. For each day of the week, there are two (with two
biocides) or four (with one biocide) dosing points available.
If a dosing point is activated by the weekly timer, then a flag for 'Biocide dosing'
(orange LED) is displayed, the associated output for that biocide is activated and the
display shows 'DOS. Biocide (X)' .
After the set dosing time, the flag for the biocide dosing is reset and the adjustable
time starts (acting time), during which the desalination remains locked. "Acting time"
is displayed.
Pre-desalination
When a biocide dosing is due, the biocide flag (orange LED) is set again. If at this time the conductivity value
is higher than the desalination threshold value Ws, the desalination is prioritised and the biocide dosing is
locked.
