Hydromat SE:
The Hydromat SE is an automatic Hydrant with hydraulic / electro-mechanical control, which is run automatically
from the snow cannon. The snow cannon reads and compares the given parameters and operates the
opening/closing of the hydrants.
The Hydromat SE is equipped with an electrical keyboard for manual operation and can, if necessary, be directly
mechanically operated on the equipment.
1.2 THE SERVICE CONSOLE OF THE AUTOMATIC SNOW MACHINE
The operating console represents the man–machine –interface of the snow machine. It shows us a display and a
row of service keys. The key group is divided into two areas: the upper gray area is where we find automatic
operation and the lower white area is where we find the manual operation.

2.0 THE KEYBOARD
On the M20 snow machine with tower the keyboard is integrated along with the control unit
in the switch box, however the keyboard is fixed on under the tower for machine service. It
is linked to the control unit with a CANbus.
The keyboard has a display with 2x20 symbols and 20 keys.
IMPORTANT: Next to the slave key you will find an emergency off key, to close off the
machine in emergencies.
It is divided into 2 operational levels: the upper gray part for automatic operation, the lower
white part for manual operation.
2.1 OPERATION OF DISPLAY, DIFFERENT MENUS AND VARIOUS LEVELS
The display has 2x20 symbols. The first line of the display shows the operational situation
(it says whether the snow machine runs automatic mode or manual), it describes the
measured environmental conditions and the calculated values (humid bulb temperature).
The second line serves for the description of the environmental parameters, the calculated
values and for the task of error reports.
The environmental parameters are the following: air temperature, water pressure, relative
humidity, water temperature. The parameters displayed are measured values.
Calculated values are: humid bulb temperature and water capacity, where the displayed
values can slightly differ from the real values.
The 3 lines show
the operational
condition of the
equipment, left to right.

2.2 FUNCTION OF THE KEYS
To control the display, the different menus and different levels there are 4 keys at your disposal: ESC, DOWN, UP
and ENTER.
The ESC key serves for being able to move from one level to the preceding one. If pressed repeatedly,
it acts to reach level 1.Moreover this key is used for leaving a menu (in the case of a level having more
than one menu) .
The DOWN key is used to leaf backwards through the menu, or to lessen values (to number off).
The UP is used to further leaf through the menu, or to increase value (enumerate).
The ENTER key will be used to move from level 1 to level 2 (and further), or to confirm changes. A
menu can be chosen with the key too.

3. AUTOMATIC REGULATION
Automatic regulation is accomplished through the sensor set, the control unit and the valve cards. The snow
machine sets itself according to the given environmental conditions to produce the required quality in snow.
If an automatic Hydrant of the type E-Motor, Hydromat or Hydromat 2000 is installed, the snow machine can also
set the water pressure independently to a required operation pressure.
3.1 THE SENSOR SET
The sensor set serves for fixing the humid bulb temperature and possesses 2 sensors, which can measure the air
temperature from –30°C to +30°C and the relative air humidity from 0 to 100%. The output measurement signal
ranges between 4 and 20 mA .
The sensors are installed in a measuring station directly on the snow machine and deliver their values directly to
the control unit, which then in turn calculates the humid bulb temperature. This humid bulb temperature forms the
basis for the snow production in the automatic operation.
Besides this, the water temperature and water pressure are measured on the jet ring. The values serve to
influence the condition of the jets and to regulate the water quantity. All sensors send their information to the
control unit, which works on the data.
The water pressure will be measured from 0 to 60 bar and converted into a measurement signal between 4 and
20 mA; the water temperature will be measured from –10°C to +30°C, and converted into a signal between 4 and
20 mA.
3.2 THE PU-080 CONTROL UNIT AND PU-79-P KEYBOARD
With the M20 AT snow machine control unit and keyboard are 2 units, which are linked through a CANbus. The
control unit is a programmable controller unit and has the functions of reading data, storing data and working on
read analog value. The control unit, to which the different sensors are connected, calculates the energy content of
the air. This calculated value will be corrected with the water pressure. A further correction will be made based on
the required snow quality. The result of the calculations results in the required amount of water leading to the
correct opening of the jets. As well as this, the control unit continually supervises the proper function of the M20.
The control unit receives the environmental data from the sensors and the set parameters from the keyboard.
Each switching process is checked and in the case of an error the corresponding error report appears on the
display and if necessary the machine will be halted. The control unit has 16 digital inputs/outputs, 6 further analog
inputs and 2 serial ports:
The RS 422-interface works in the (ATASS) network and the RS 232-interface serves for serial communication
with a PC.

keys can be pressed, to see the description of the shown value in the upper lines.
After the starting phase, for which the heating will always remain switched on, the heating will be switched on and
off for variable time periods, depending on the air temperature.
At the same time the snow machine starts positioning. The turbine swings downwards, to the end switch, then it
goes to the set position (in the case of a built-in electric motor).
In the meantime the compressor will be switched on, its warm running time depends on the measured air
temperature.
On the display the letter Kappears on the second line position as will be seen in illustration 5:

Finally the hydrant will be opened.
ATTENTION (in the case of an automatic hydrant available)!
When a minimum pressure of 8 bar on the jets is not reached within a short time span, then a corresponding error
report will be given and the machine will be halted.
If a smart hydrant such as Hydromat SE, Hydromat 2000 or E-Motor is connected to the snow machine, the
machine will open the hydrant automatically.

IMPORTANT
In the case of manual hydrant installation, then this must be opened within 60 minutes.
OPERATION:
Now the snow machine is in operation.
During this phase the following should be considered:
The water pressure will be regulated by means of opening and closing the hydrant.
The switchable jets will be opened and closed depending on the humid bulb temperature, the water
temperature and the water pressure.
Snow control: check the quality of the snow produced where it mostly collects.
There is the possibility to change the set snow quality.
Continually supervise the correct running of the machine, even when it is in automatic mode.
ATTENTION
When the machine is in operation, do not stand in front or at the back of the
running turbine!

Illus. 7
You see from the display that the machine is in the stop phase(***STOP*** ) but the turbine (T), the compressor
(C) and the heating are (H) still in operation, these will be automatically switched off at a given moment.
In the case of installation of a smart hydrant such as Hydromat SE type, Hydromat 2000 or E-Motor, then there will
be automatic closure by the snow machine.
IMPORTANT
In the case of manual hydrant installation, then closure must follow within 60 minutes by hand.
As soon as the machine is turned off, the water hose must be separated from the machine and emptied.
ATTENTION
In the case of an apparent machine error, the warning light will flash.

Now simply press the START key , to set the snow machine in motion.
If the automatic start is active and the START key pressed before “Ready” is shown, the cannon will not
start. The report Wait... (illustration 10) appears. The cannon then waits until the environmental conditions set on
to “snow readiness”. Then the machine can start by itself.
illustration 10
After the above-described start phase data, you here see the necessary indications:
After pressing the START key the heating will be switched on and shown on the display (illustration 11):
Bild 9
Illus. 11
After the startup phase, in which the heating always remains on, the heating will constantly be switched on and off
for longer or shorter periods depending on the air temperature.
In the case that the snow machine is fitted with a motor for vertical adjustment, the snow machine begins
positioning. The turbine swings downwards, up to the end switch, then it positions itself in the set position. See
display (illus. 12)

The equipment now begins to swing, in the case that a swing width larger than 0 is set.
Then the turbine will start off and the hydrant will be opened, if an automatic hydrant is connected (illus 15).
In the case that only a manual hydrant has been installed, the snow machine waits for the opening by the user.
ATTENTION
In the case that the hand operated hydrant is not opened within 60 minutes, an error report appears on the display,
and the machine will be stopped.

STOPPING THE M20 SNOW MACHINE FROM THE “STATUS” DATA FIELD
Also when stopping the snow machine, all steps that the machine is carrying out can be supervised from the
“Status” data field.
If the STOP key is pressed, the following appears on the display (illustration 15):
illustration 17
The next step is closing the valves and the hydrant. When an automatic hydrant has been installed, this will be
closed by the snow machine itself, otherwise the snow machine waits until the hydrant will be closed manually by
the user (illustration 16).
illustration 18
ATTENTION
When the manual hydrant has not been closed within a period of 60 minutes, then an error report appears on the
display and the machine keeps running, as long as the water pressure does not sink to under 2 bar
(The automatic hydrant needs a shorter switch off time.)
With the closing of the hydrants, all valves will be closed at the same time. In the case of jet ring pressure of more
than 2 bar, all valves will be opened, so as to improve emptying.
After this phase the turbine will be switched off (illustration 19).
Illus. 19
The compressor will be immediately stopped after the switching off of the turbine.
As soon as the compressor is switched off, the turbine pipe goes to the vertical position. The remaining
water can then flow from the jet ring and icing over will be avoided.
