Check if there are any obstacles that block any of the outlet piping lines connected to the Treatment Tank. Remove the pressure
switch from the ECOmar S treatment tank; clean it; and check if it is correctly set. If the pressure switch is not set to the correct
value (refer to the attached Test Report - usually 0.2bar), reset it according to the following steps:
1.
Install the pressure switch between a pressure gauge (your supply) and a two-way ball valve (your supply);
2.
Remove the connector on the top of the pressure switch;
3.
Connect the probes of the ohmmeter (your supply) to the pressure switch terminals. The ohmmeter will measure the
electrical continuity signal;
4.
Totally open the two way ball valve installed after the pressure switch;
5.
Pressurize the line by closing slowly the two way valve;
6.
If the ohmmeter gives no electrical continuity signal, before reaching the correct pressure value (refer to the attached
Test Report - usually 0.2bar), tighten the pressure switch screw and repeat the steps starting with step 3 of this list.
7.
Bring the line to correct pressure (refer to the attached Test Report - usually 0.2bar), closing slowly the two way ball
valve, and turn the pressure switch screw counterclockwise until the ohmmeter gives no electrical continuity signal.
8.
Repeat the procedure for further adjustment of the pressure switch threshold.
9.
At this point the pressure switch is set to shut down the system at the correct pressure value (usually 0.2bar).
10.
Re-install the pressure switch on the ECOmar S treatment tank.
Once the fault that has caused the alarm signaling is solved, you can reset the alarm signaling by pressing the STOP/ESC key.
At this point the alarm signaling will be reset and the display will show:
Press again the STOP/ESC key to return to system the main page. Then, restart the plant by pressing the START/ENTER key,
the system will begin to run from the filling step if the liquid level inside the Treatment Tank is below the min level of multilevel
sensor; otherwise from the chemical dosing phase.

Remote control for ECOmar S - model: CDMAR2 (optional)
The remote control CDMAR2 is available only when the
automatic
mode is active (in
manual
mode the system can be run
only from the Main Control Box); otherwise an error message appears on the display “Local Control”.
The remote control is provided with three key buttons with the following functions:
•
START
-
Run the system. If the system is running, pushing it repeatedly to show the system status.
•
STOP
-
Stop the system.
•
RESET
-
Clear further warning alarms for any failure.
This remote control displays all the alarms signaling as the Main Control Box, except the Sludge Tank Overflow Alarm that
has the same signaling as the Filling Alarm. This remote control also allows to examine the system status pages.
WARNING:
It is not possible to run the system with more than one different model/type of remote control at the same
time, even if the Main Control Box is arranged to be connected to several remote controls.
