ECOMATIC-S
GENERAL DESCRIPTION
Economisers in the ECOMATIC-S-ATEX range are digital sequential timers with built-in differential
pressure switches certified Atex zone 22.
The versions ECOMATIC-S4, ECOMATIC-S6, ECOMATIC-S12, ECOMATIC-S20 and
ECOMATIC-S32 enable control of up to 4, 6, 12, 20, and 32 solenoid valves respectively. The version
ECOMATIC-S64 is equipped with an expansion card with 32 outputs, expanding control capacity to up
to 64 solenoid valves. In the same way, the model ECOMATIC-S96 is equipped with 2 expansion cards
for capacity expansion up to 96 solenoid valves.
In all versions there is a display with 3 digit that can display the differential pressure unit of programmed
(tens Pa, mmH
2
O, mbar, kPa and mmHg) or the number of the cleaning valve; the three keys also enable
programming of parameters on the instrument according to personal requirements including, pause time,
operation time, post-cleaning time (or number of cycles) and washing start and end pressure, post-
cleaning pressure, alarm pressure and operation mode (automatic/manual) .
All models are equipped with LEDs to display activation of outputs, pause phases and power on, the
power supply presence, the post-cleaning status, and so on and so on.
The controllers with AC power supply are able to control both electronic valves with AC input and
electronic valves with 24VDC. The output stage is made up of triac with on/off to zero-crossing to
reduce noise.
Each model is supplied in polycarbonate enclosures with transparent lids and IP66 protection rating.
On demand, the ECOMATIC-S instruments can be provided of an ACTIVE analogical output
proportional to the pressure read by the sensor. The pressure interval allowed is programmable through
two parameters: “P14” e “P15”.

ATEX CERTIFICATION
This series of devices is certified in accordance the European norm ATEX (94/09/EC) and they have
been planed and constructed for the use in places where could be potential explosive atmospheres due to
dusts.
The rate of protection offered against explosion dangers is codified in the marking CE-ATEX situated
on the device.
Naturally, the safety of the people is important, is necessary and law compulsory that all the people
involved (device manufacturer, planners system, constructor, installer, final costumer, maintainer, etc)
must be aware of the obligations and follow the imposed procedures.
It is necessary to read this manual carefully and control that elements mentioned by the constructor
would be
suitable for the elements of the places where the device will function.
It is also necessary to read the remarks regarding installation device, its correct use while its operative
life, the correct procedures in case of trouble and/or maintenance. This remarks are exposed in the
special chapter of this manual.
Each ECOMATIC-S-ATEX is given by Autel s.r.l. equipped by a declaration of conformity CE-ATEX,
the manual and a plate in accordance to the directive 94/9/EC having the marking ATEX.
The marking ATEX of this device is:
II 3D Ex tc IIIB T 90°C IP66 Dc
This marking indicates that while the operation runs, the device operates in places where an explosive
atmosphere caused by dusts (D) could rarely occurs and in short time (operation in the zone 22). The
device is equipped for give a normal level of protection in normal conditions and this does not form an
ignition source during standard functioning. The anti-explosion method of protection is identified by the
word “tc” indicating the protection method by IP6X rating enclosure.
It is guaranteed that in case of troubles, the maximal external temperature in every place of the container
would not increase 90° C.
This is an important matter for the planner, the installer and the maintainer for determine which is
maximal thickness of the layer of combustible gas that is allowed to deposit on the device surface before
a cleaning.
Besides, they must verify that the temperature of 90° C need to be inferior of ⅔ of minimal temperature
of the combustible dusts ignition present in the system and that could determine a potential explosive
atmosphere.

ECOMATIC-S POWER SUPPLY
All the ECOMATIC-S models can have as power supply 3 different tensions 24 Vac, 115 Vac e 230 Vac.
The power supply has to be connected in this way (according to the chosen power supply).

Power supply
Note
• The power supply has to be sectioned upstream of the equipment;
• Both for the economizers and the electrovalves has to be done the earth connection;
• You have to use shielded cable, far from noise sources, like Inverter power cables and engines in
general.
ELECTROVALVES CONNECTION SCHEME
The solenoid valves are connected between output terminals 1 -2 ... - N and terminal C (common) which
is connected to a suitable power supply via an external connection.
The controllers are equipped with more than one common terminal: obviously they are all
interconnected and therefore do not require additional external connections.
According to the power supply given to the unit it is possible to use some types of electro valves. Here
following the options:
• Power supply 24 Vac: it can be used 24 Vac or 24 Vdc electronic valves
• Power supply 115 Vac: it can be used 24 Vac, 115 Vac or 24Vdc electronic valves
• Power supply 230 Vac: it can be used 24 Vac, 115 Vac, 230 Vac or 24 Vdc electronic valves
In case of controller’s power supply with DC it is necessary to indicate it at the purchase order phase in
order to adapt the circuit at this kind of output.
CAUTION
Ensure that the power supply is disconnected before making or modifying
cable connections.

ECOMATIC-S
For the load’s connection has to be done an external bridge connected according to the voltage of used
electronic valves (to do the connection between the terminal C (common), and the power supply
terminal, corresponding to the operating power of the electro valves). If you forget to do this
connection, the electro valves will not be driven: the instrument will quickly scan all the outputs (the
LEDs on the outputs will be switched on for a short time, and the pause LEDs will quickly blink)
without activating any electrovalve.
N.B.: In the case of electro valves with 24DC, the connection bridge for the power supply of the load
has to be done with ComOut 24VDC (output common with 24Vdc) and the terminal C (Common). This
voltage is automatically created by the card and therefore it must not be supplied from outside.
The following pictures show the different kinds of connection that have to be made according to the
working voltage of the electrovalves.

ECOMATIC-S
Control of electrovalves in parallel on a single output or multiple shot on more then one output.
ECOMATIC-S cards are able to control up to 2 Electrovalves for a single output, or to activate up to 4
outputs at the same time for 110V/220V power supply and 2 outputs at the same time for 24VAC/DC
power supply.
ATTENTION: to activate more than one electrovalve in parallel or on various outputs,
you need to have the same tension for valves power supply and instrument power supply.
In this way, the requested power is supplied by the supply net (e.i. instrument power
supply 230VAC and coils 230VAC).
CAUTION
In all the models of ECOMATIC-S, in the case you have to drive two electrovalves at the same
time, the value of two fuses on the board has to be changed:
- the one for general protection of 2A quick has to be changed into 4A quick and the one for
load protection of 1.6A delayed has to be changed into 3.15A delayed.
In particular, in the versions ECOMATIC-S 64/96, the connection of the double electrovalves to
the outputs on the expansions has to be done according to the following scheme:
1
st
expansion (both ECOMATIC-S64 and ECOMATIC-S96)
Internal connection
2
nd
expansion (just in the ECOMATIC-S96)
Internal connection
Note: For connecting the load of the double electrovalves on the expansions (ECOMATIC-S 64/96) it is
necessary to do one connection between the terminal C (common) of the expansion board and the
terminal C of the ECOMATIC-S32 board. We suggest you to put the cables of electrovalves far from
noise sources, like inverter power cables and engines in general.
