WORKING PRINCIPLE AND OPERATION MODE
Daily programing
If the «AUTO/MANU» button is in position “AUTO”, the
power plant operates according to a daily schedule from
Monday to Friday from 7:00 am till 7:00 pm. Schedules
are modifiable. Consult us.
In position “Manu”, the power plant operates
continuously 24h / 24h and 7j / 7j.
The working principle is identical to the standard version. The opening and closing of the isolation valves B of the tank 1 and 2 are associated as well as
the drainage valves D. Activation of the detectors of the tanks 1 or 2 starts the emptying of the 2 tanks.
CIRCUIT DIAGRAM. DOUBLE CENTRAL 393104.
WORKING PRINCIPLE
1. Vacuum pump running
The vacuum pump switches on automatically when the Time Prog = ON, on
lack of vacuum (if sensor option) and during emptying phases.
The vacuum pump can be stopped by the «OFF/ON» button.
A message appears on the screen.
In case of disjunction, an alarm is triggered by displaying “*ALARM*”
flashing on the main page, then you must go to the alarms page.
Option: If the pump is equipped with an oil level sensor and it is activated,
it will only be taken into account after 60 seconds and will block the
operation of the pump. An oil fault alarm will appear.
NOTE: In the case of 2 vacuum pumps, both pumps operate at the same time.
2. Liquid pumping
Valves status:
A(pneumatic valve for isolating pump): open.
B(pneumatic valve for isolating network): open.
C(pneumatic valve for air inlet): closed,
D(pneumatic valve for drain): closed.
3. Draining
The pump is switched off during this phase.
The emptying can be triggered by 4 events:
• at each power-up and from Monday to Friday at 7H00,
• 5 hours after switching on,
• press the drain push button,
• triggered by the level sensor.
A message on the PLC indicates which of the events has activated the draining.
4. Pumping operation to draining operation
Valves A and B are closed to isolate the network and pump.
Valve C opens: the pressure in the receiver increases. It is limited by a
regulator set at 0.4 bar.
If the pressure in the receiver doesn’t reach +400 mbar after “Pressure
flushing” – 10 seconds (120s - 10s = 110s), the “P.FLUSHING” alarm is
triggered. Emptying and suction are stopped.
Valve D only opens after 60 seconds (vacuum breaker time - parameter can
be changed). The liquid is drained from the receiver and the emptying lasts
5 minutes (parameter can be modified).

TOWARDS
THE PUMP
ACCIDENTAL
LIQUID INLET
INSTALATION
NETWORK CONNECTION
In order to transport the liquid correctly and avoid the losses in the lines, we
recommend 2’’piping. It must not exceed a maximum height of 3 meters from
the ground. Plan a slight slope towards the tank to avoid a low point at the end
of the line.
VACCUM CHANNEL
Connect the tank drainage to allow automatic drainage.
With respect to the ground, piping should not exceed two meters.
PNEUMATIC SUPPLY
Supply compressed air to the decompressor with a maximum pressure of 6
bars, with clean air without moist. The pressure after the regulator valve is
set at 0.4 bars and the safety valve at 0.5 bars.
The regulator and discharge valve are adjusted and preset from factory.
Incorrect setting of these items can cause high pressure in the tanks
which are not intended for operation in such conditions.
!
ELECTRICAL SUPPLY
All operations on the machine must be carried out without electrical power.
The connection must be made by a qualified electrician.
All operations on the machine must be carried out without electrical power.
The connection must be made by a qualified electrician.
Check in the motor plate or in post plate that voltage corresponds to that of
the electrical grid.
Feed the workstation with an electric cable whose section corresponds to the
max power.
All motors are protected with a magnetothermic switch.
1.1 kW for 393103 and 393104, 2.2 kW for 393105 ie 1.5 mm²
Power supply L1 - L2 - L3 - Neutral + earth (400V).
The protections to be installed would be 4A for 393103 and 393104 and
10A for 393105.
Refer to the electrical diagram.
!
COMMISSIONING
Check the oil level of the vacuum pump.
Before starting up, read the set up and maintenance manual of the
vacuum pump.
Set the main switch (IG) to I (run) position and press immediately the red
“STOP” button to stop the pump.
Press the green button “RUN” to make the pump rotate and check
immediately the direction of rotation. An arrow indicates the direction of
rotation in the motor. If the direction is not correct, stop the pump
immediately with its M / A button. Reset the correct direction of rotation
swapping the two phases.
Allow the system to increase the vacuum and then proceed to the suction
operations.
Vaccuum can be activated:
• With each connection to the electrical power supply.
• 5 hours after the electrical power connection.
• With the activation button of the box.
• By detecting the level with the level sensor.
WORKING PRINCIPLE AND OPERATION MODE
WORKING PRINCIPLE
5. Draining operation to pumping operation
Valve C is closed: the pressure in the receiver drops. After 30 seconds (flush
time), valves A and B are open and valve D is closed.
6. Liquid trap to protect the vacuum pump:
The liquid trap is a safety device. If, accidentally, the maximum level of the
receiver is reached, the liquid can migrate towards the pump. It will be
trapped before the pump by the liquid trap.
If the quantity of liquid is very important, the level of the liquid trap increases
and, at its maximum level, an obturator cuts the vacuum.
The liquid trap must be emptied:
• Switch off the vacuum pump.
• Open valve so that the liquid fills glass jar.
• When the glass jar is full, close the valve.
Unscrew the glass jar and empty its contents into a
suitable recipient for subsequent recycling according to
environmental protection legislation.
Screw the glass jar back on and repeat until the jar is empty. It is possible
that the mechanical obturator will remain in the up position once the
emptying is complete. Just open the valve and close it again.

automatically nullifies the manufacturer’s guarantee.
• For your safety and to avoid your own liability, only use MIL’S parts when
replacing malfunctioning or broken down items.
• The immediate superior should be notified of all maintenance or testing
operations on the equipment.
• During all maintenance operations the work area must be clearly delimited
by white lines. At night, the area should be adequately lit.
• The lifting points are indicated by the or pictogram. During
lifting operations, the machine must not be hoisted from any other point.
• If the machine has to be hoisted and moved for siting or maintenance
operations, check that adequate lifting gear is used and familiarise
yourselves with all the safety regulations surrounding the lifting of
machinery.
• Under no circumstances should the machinery be needlessly suspended
(during meal breaks, outside working hours, etc.)
• Following any work or repair on a machine function, carry out a check to
see that this function has been rectified before using the machine.
PLANNING MAINTENANCE OPERATIONS
Many accidents can be avoided by organising maintenance operations. The
supervisor must be clear about the tasks to be carried out and the possible
risks involved. He should draw up a maintenance plan and explain it to all
the people concerned so as to limit the risk of accidents.
The following pointers should be taken into account (non-exhaustive list):
• Which team members are needed for the work and what are their
responsibilities?
• What is the weight of the load that may have to be lifted?
• What tooling is required for the job and how is it to be conveyed to
the work area?
• What equipment is required to lift the equipment in absolute safety?
ELECTRICITY
• The supply voltage must not vary by more than 10%.
• An appropriate thermal relay is required for approved connection. The
safety trip rating of the motor must equal the motor rating given on the
manufacturer’s plate.
• After connecting the motor or after each reconnection use a phase
indicator to check the direction of rotation of the motor.
• The machine must be powered down whenever an electrical component
is replaced.
• Before carrying out electrical connections on the machine, check that the
voltage and supply frequency prevailing in the country of usage are
identical to the operating voltage of the machine.
The electricians commissioned to set up the machine are entirely responsible
for the sizing of the electricity supply cable as well as all external cabling.
The electrical connection of the machine must be carried out by a
qualified electrician in compliance with regulations prevailing in the
country where the machine is in use.
• Before carrying out any breakdown repairs or servicing, the machine must
be partially or totally isolated and taken out of service.
• Any person carrying out servicing or breakdown repairs on a powered
machine, must be qualified and suitably skilled to carry out such
operations within that context. The machine must be partially taken out
of service to prevent any other person starting it up.
• In the case of an electrical power cut or the tripping of a safety device,
automatic restart of the machine must be disabled under all circumstances.
• Do not carry out any electrical connection or disconnection without knowledge
of the circuitry. A faulty connection may cause personal injury or damage.
• Never wear any rings, bracelets or any other metallic object likely to earth
a powered circuit, thereby causing burns.
• Following any work or repair on a machine function, check that this
function has been rectified before using the machine.
• If maintenance operations are carried out on the machine while powered
up, sparks may be produced on the electrical circuit. Do not work in
confined areas in the presence of inflammable material, dust or vapour
which could cause explosions or fires. Failure to observe this rule could
result in personal or fatal injury.
FLUIDS
• A vacuum pump must be connected to suction piping without any
mechanical stress. You are recommended to install flexible piping between
the pump and the installation.
• A compressor, wherever possible, should be connected up for use by a
pressure resistant flexible hose.
• The suction pressure of vacuum pumps must never exceed atmospheric pressure.
• The cross-section of vacuum pump exhaust lines must be at least as great
as that of the pump connection hole. Too small a diameter on the line
may create unacceptable pressure in the pump.
• No part of the casing should be exposed to vacuum or pressure.
• Do not start a vacuum pump running if its exhaust lines are blocked or
constricted. Before starting the pump, check that the exhaust line is open
and that it is free of any deposit that may have built up inside it.
• The choice of pipe materials should be appropriate for the process fluid.

PRINCIPIO Y MODO OPERATIVO
Programación diaria
Si la tecla “ Auto / Manu “ está en posición “Auto”, la
central funciona según un horario diario de lunes a viernes
de las 7h 00 a las 19h 00.
En posición “ Manu “, la central funciona continuamente
24h/24h y 7d/7d.
El funcionamiento es idéntico que la versión estándar. La apertura y el cierre de las valvulas de aislamiento B del depósito 1 y 2 están asociados así como
las valvulas de vaciado D. La activación de los detectores de los depósitos 1 o 2 pone en marcha el vaciado de los 2 depósitos.
DIAGRAMA DEL CIRCUITO. CENTRAL DOBLE 393104.
PRINCIPIO DE FUNCIONAMIENTO
1. BOTÓN « ON/OFF » DE LA BOMBA DE VACÍO
2. BOTÓN « AUTO/MANU »
3. PULSADOR PARA LANZAR UN VACIADO
1. Funcionamiento de la bomba de vacío
La bomba de vacío se pone automáticamente en marcha cuando el Time
Prog = ON, al faltar vacío (si opción sensor) y durante las fases de vaciado.
Puede pararse con el botón “OFF / ON”.
Aparece un mensaje en la pantalla.
En caso de disyunción, se dispara una alarma mostrando “*ALARM*”
parpadeando en la página principal, luego debe ir a la página de alarmas.
Opción: Si la bomba está equipada con un sensor de nivel de aceite y se
activa, sólo se tendrá en cuenta después de 60 segundos y bloqueará el
funcionamiento de la bomba. Aparecerá una alarma de fallo de aceite.
Nota: En el caso de 2 bombas de vacío, bombas funcionan al mismo tiempo.
2. Fase aspiración líquida
Estado de las válvulas:
A(válvula neumática de aislamiento bomba): abierta
B(válvula neumática de aislamiento red): abierta
C(válvula neumática de admisión de aire): cerrada
D(válvula neumática de vaciado): cerrada
3. Fase vaciado
La bomba se detiene durante esta fase.
El vaciado puede activarse por 4 medios:
• Cada vez que se conecta a la red eléctrica y de lunes a viernes a las 7H00,
• 5 horas después de la conexión a la red eléctrica,
• Al pulsar en el pulsador de vaciado,
• Activado por el sensor de nivel.
Un mensaje en el PLC indica cuál de los medios ha activado el vaciado.
4. Paso de la aspiración al vaciado
Las válvulas A y B se cierran para aislar la red y la bomba.
Apertura de la válvula C: aumenta la presión en el depósito. Está limitado por
un regulador ajustado a 0,4 bar.
Si la presión en el depósito no alcanza +400 mbar después de 10 segundos
(120s - 10s = 110s), se activa la alarma “P. CHASSE”. El vaciado y la succión
se detienen.
La válvula D sólo se abre después de 60 segundos (tiempo para romper el
vacío - parámetro modificable). El líquido se drena del depósito y el vaciado
dura 5 minutos (parámetro modificable).

PRINCIPIO Y MODO OPERATIVO
5. Paso del vaciado a la aspiración
Válvula C se cierra: la presión en el depósito baja. Después de 30 segundos
(tiempo de vaciado), las válvulas A y B se abren y la válvula D se cierra.
6. Función del frasco de protección con nivel visible:
El frasco de protección con nivel visible es una seguridad. Si, accidentalmente,
el máximo. del depósito, el líquido puede migrar hacia la bomba. Quedará
atrapado antes de la bomba por el frasco de protección con nivel visible.
Si la cantidad de líquido es muy importante, el nivel del frasco aumenta y,
en su nivel máximo, un obturador corta el vacío.
Debe ser vaciado:
• Poner fuera de servicio la bomba de vacío.
• Abrir la válvula para que el líquido llene el frasco.
• Cuando éste está lleno, cerrar la válvula.
Destornillar el frasco y vaciar su contenido en un recipiente
destinado a ese fin para un reciclaje en conformidad con la
protección del medio ambiente.
Roscar el frasco y repetir la operación hasta que el bote quede vacío.
Es posible, una vez terminado el vaciado, que el obturador mecánico
permanezca en posición alta, basta con abrir la válvula  y cerrarla de nuevo.

INSTALACIÓN
CONEXIÓN A LA RED
Para que el líquido se transporte correctamente y evitar las pérdidas en las líneas,
recomendamos una canalización de 2”. No debe superar una altura máxima de
3 metros desde el suelo. Prevea una ligera pendiente en dirección al depósito
para evitar un punto bajo en el extremo de la línea.
CANALIZACIÓN DE VACIADO
Conectar el vaciado del depósito para permitir el vaciado automático.
Respecto al suelo, la canalización no debe superar dos metros.
ALIMENTACIÓN NEUMÁTICA
Suministre aire comprimido al descompresor con una presión máxima de 6
bares, con aire limpio y no húmedo. La presión después de la válvula
reguladora está ajustada a 0,4 bares y la válvula de seguridad a 0,5 bares.
El regulador y la válvula de descarga están ajustados y alineados de fábrica.
El desajuste de estos órganos puede ocasionar una fuerte presión en
los depósitos que no están previstos para un funcionamiento en
tales condiciones.
!
SUMINISTRO ELÉCTRICO
Todas las intervenciones en la máquina se deben realizar sin tensión
eléctrica.
La conexión la debe realizar un electricista cualificado.
Comprobar en la placa del motor o en la placa del puesto que el voltaje
indicado corresponde al de la red.
Alimentar el puesto con un cable eléctrico cuya sección corresponde a la
potencia máx.
Todos los motores están protegidos de fábrica con un magnetotérmico.
1.1 kW para 393103 y 393104, 2.2 kW para 393105 es decir, 1,5 mm²
Alimentación L1 – L2 – L3 – Neutro + tierra (400V).
Las protecciones a instalar serían de 4A para 393103 y 393104 y 10A para
393105.
Consulte el diagrama eléctrico.
