2 General
The filter mobile is subjected to a detailed final control check in the works. Therefore small quantities of diesel oil can still be present in the device. These remaining quantities do not impair either the storage or the function of the device.
3 Notes on safety
The two available connections for the supply voltage (Connection 1: Mains supply line for 115 V AC or 230 V AC. Connection 2: Connection for 12 V DC battery operation) may not be used simultaneously. Operation at any operating voltages other than listed in the technical data is not permissible. Employment in explosion-hazard areas is not allowed. The maximum ambient temperature for the operation of the filter mobile is 40°C. If the electrical cables should indicate damage, switch off the filter mobile immediately using the emergency switch and disconnect from the supply voltage (pull plug or with 12 V operation remove terminals from the battery). In case of damage to the bus system and the filter, the filter mobile may also not be employed since otherwise fuel can reach the environment.
The pump motor and the supply line can warm up considerably during operation. Touching these parts is to be avoided to protect against burn injuries.
If the filter mobile is operated at ambient temperatures above 25°C, the operator interface can warm up considerably!
In order to avoid the discharge of fuel residues, the fuel filling nozzle and the shut-off valve must be closed after the use of the filter mobile.
3.1 Utilisation according to specification
Provide diesel oils and mineral oils with a dynamic viscosity < 10 mPas, a flash point > 55°C and a boiling point > 160°C. The utilisation of liquids which can attack the filter casing (aluminium), the pumps (steel), the plastic parts (polyamides) and the seals (NBR) is not planned, and can lead to damage to the filter mobile or to dangerous operating states.
All work on the SWK-2000/40/WSA filter mobile must be implemented in voltage-free status.

10.2 Pump and filter operation
After connection to the supply voltage, the operating voltage is switched on by acknowledgement of the emergency switch (pull switch button upwards).
The green operation indication (LED) and the display light up. After the initialisation (initialisation signals always in German), the following switch-on signal is indicated on the display for approx. 2 seconds:
The version numbers, the serial number and the date of manufacture can also be other numerical values, according to implementation.
After that, the selected operating modes are displayed for approx. two seconds:
You can find an explanation of the operating mode in Chapter 10.4.
After successful self-test, the display indicates:
The ”-” character in the second line at the left edge indicates the function of the left key and the ”+” character in the second line at the right edge indicates the function of the right key. Dependent on the font of the display employed, the characters can vary slightly at the left and right line edge. In the lower line is displayed the temperature status of the electronics and pump motor. In this case
”TE: OK” means: the temperature of the electronics is within the planned range, and ”TM: OK”
means: the temperature of the pump motor is within the planned range. Before beginning the pump and filter operation, the shut-off valve and the fuel filling nozzle are to be opened. The filter mobile is now ready for operation.

For the start of the fuel pump, the right-hand key ”+” must be pressed shortly. The pump ramps slowly up to a supply capacity of approx. 15 l/min. Smaller flow rates cannot be adjusted. If the key ”+” is pressed longer, the supply capacity of the pump can be increased to approx. 40 l/min. The instantaneous supply capacity can be read off in the display behind the brackets in l/min. The actual supply capacity depends on many external influences, and can therefore deviate from the indicated
supply capacity. An actuation of the key ” – ” reduces the supply capacity. With an indication of 15 l/min, an actuation of the key ” – ” results in the disconnection of the pump. If both keys are pressed
simultaneously, the pump is also switched off. For the duration of the key activation, the key function is displayed between the brackets.

10.2.1 Timer function
The filter mobile is equipped with a timer function, with which allows the pump to be operated for a preselected time. The pumping procedure is ended automatically after this time.
10.2.1.1 Adjusting the required runtime
The runtime can be adjusted in intervals of 15 minutes, up to a maximum of 2 hours. In order to initiate this setting-adjustment process, the key ”Timer +” must be pressed with pump operation switched off. In the display, the following indication appears:
A minimum runtime of 15 minutes is already preset. As a result of actuation the keys ”Timer +” and
”Timer –”, the required runtime can be adjusted. If the keys ”Timer +” and ”Timer –” are activated
simultaneously, the procedure is interrupted and the control returns to the basic status. When the timing has ended, this setting menu can be exited with the key ”+; faster”.
With the keys ”+; faster” and ”-; slower”, the required pumping capacity can be adjusted as described in Chapter 8.2. The residual runtime of the pumps is updated continuously in the display. After this time the pump switches off automatically and the filter mobile returns to the basic status. Every time-controlled pump operation is implemented only once.
10.2.1.2 Timer operation interruption
The simultaneous actuation of the keys ”+; faster” and ”-; slower” or the actuation of the Emergency Off switch interrupt the timer operation and end the pumping procedure. The filter mobile returns to the basic status.

10.2.2 Fault reports
If the operation indication does not light up with proper connection of the supply voltage and after the reset-acknowledging of the emergency switch, there is an internal defect. In this case, the repair must be implemented by the manufacturer.
10.2.2.1 Operating voltage too high
If, in battery operation, a voltage of more than 15 V is connected by mistake (e.g. 24 V through series switching of two 12 V batteries), a fault report appears in the display:
The fault report is deleted by connection of the correct operating voltage and a new start.
10.2.2.2 Operating voltage too low
If, in battery operation, a voltage of less than 10 V is connected by mistake (e.g. 6 V battery, as in very old vehicles), a fault report appears in the display:
The fault report is deleted by connection of the correct operating voltage.

10.2.2.3 Temperature of the pump too high
For the protection of the pumps, the filter mobile is equipped with an automatic temperature and load-dependent pump control. To avoid pump temperatures which are too high, this regulation reduces the power consumption of the pumps as appropriate. As soon as this regulation intervenes in the pump control, this status is indicated by ”!”.
If, during operation, the motor temperature of the pump exceeds the permissible limit value in spite of regulation, the pump is switched off and the following signal appears in the display:
The pump can be switched on again only when the pump motor has cooled down.
10.2.2.4 Too high temperature of the electronic control
If, during operation, the temperature of the electronics exceeds the permissible limit value, the pump is also switched off and the following signal appears in the display:
The pump can be switched on again only when the electronics has cooled down.
An excessive amount heat with the pump or electronics can have various reasons; amongst those are too high ambient temperature and a too high viscosity of the pumped and filtered media.

10.3 Selection of the display-language
The signals in the display can be displayed in 8 different languages. In order to select the required language, the filter mobile is connected to the supply voltage and the emergency switch activated. If the keys ”+” and ”–” are activated simultaneously during switch-on procedure (unlocking of the emergency switch), the menu for the selection of the required language is accessed.
The character ”<” behind the respective language shows the currently selected language. With the key ”–” a change can be made between the different languages. The character ”<” then skips to the next possible language. With the key ”+” the language is selected, behind which the character ”<” is
displayed momentarily. If e.g. German is selected, as can be seen in the above illustration, in the display there appears the signal:
If e.g. Polish is selected, there appears:
The language selected in each case is stored and retained for the following operation, also when the filter mobile is switched off and on again.
After the language selection, the filter mobile changes into standard operation, as described in the previous sections.

10.4 Automatic pump disconnection and dry-running monitoring
The filter mobile is equipped with an automatic disconnection of the pump motor. As soon as the fuel filling nozzle dips into the fuel with on-going pumping, the fuel filling nozzle closes automatically. So that the fuel pump does not continue to remain in this operating state unnecessarily, the electronic control switches the pump off approx. 2 seconds after the fuel filling nozzle was closed.
Under certain circumstances (e.g. large net positive suction heads, low temperatures or operation
with highly viscous fuels) faulty disconnections of the pump motor can result. For such cases, the
automatic pump switch-off can be disabled.
The dry-running monitoring switches off the pumps if no fuel has been suctioned for longer than 5 minutes. For a secure function, the shut-off valve and the fuel filling nozzle must be open.
Under certain circumstances this function can also lead to faulty disconnections (e.g. if the fuel
indicates a very low viscosity). For such cases, the dry-running monitoring can also be disabled. If
the automatic pump disconnection or the dry-running monitoring, or both functions, have been
switched off, the operator is responsible for the manual disconnection to avoid damage.
10.4.1 Selection of the automatic pump disconnection and the dry-running monitoring
The operating mode of the pump can be changed from automatic disconnection to manual disconnection. In order to select the required operating mode, the filter mobile is connected to the supply voltage and the emergency switch activated. If the timer keys ”+” and ” – ” (in this case the two left-hand keys) are activated simultaneously during the switch-on procedure, the menu is accessed for the selection of the required operating mode. In the display, the following signal appears:
The timer keys “+” and “-” can now be released. With the keys “+” and “-” (in this case the two right­hand keys), the operating mode can be selected.

The key “+” selects the automatic operating mode, with which the pump motor is switched off
automatically after the closing of the tap. In the display the signal appears:
The key “-” selects the manual operation, with which the pump motor can be switched on and off manually only. In the display the signal appears:
Directly after this signal, the selection menu for the dry-running monitoring appears.
With the keys “+” and “-” (in this case the two right-hand keys) the dry-running monitoring can be switched on and off. The key “+” selects the automatic operating mode, with which the pump motor
is switched off after approx. 5 minutes in case of dry running. In the display the signal appears:
The key “-” selects the manual operating mode, with which the pump motor must be switched off manually in case of dry running. In the display the signal appears:

10.5 Water sensor
After switching on the operating voltage, the water indication, independent of the medium in which the sensor surfaces are located, does not display any water. About 1 second later, the measurement procedure starts. The water sensor implements the necessary measurements over more than two surfaces in the medium to be examined.
After the assessment, the result is output over the display and the red LED. The indication is implemented in all cases delayed, in order to avoid a flickering of the indication in case of fluctuating medium.
Normal operation: The sensor is flushed with fuel. The red LED remains dark. In the display,
no signal is output.
Water in the fuel: The sensor is flushed with water. The pump is switched off. The red LED
lights up and the following signal is output in the display:
This signal remains present until the shutdown of the operating voltage, even when no more water flushes the sensor. The filter mobile can be put into operation again only when the water has been removed from the bowl, as described in Chapter 11.1.1.
Faults in the sensor: The red LED changes into flashing mode. In the display the signal ”Too
much water” appears in the same rhythm. After removal of the fault, red LED and the display again indicate the result of the measurement.

11 Notes on use
The SWK-2000/40/WSA filter mobile may not be employed in case of damage to the filter casing, the supply lines and the electrical cables. In this case, repair is necessary with the manufacturer.
The water sensor may not be employed with damaged measurement tip. For better identification of damage, the measurement tip is painted green. Scratches or paint-free surfaces indicate damage to the sensor and require the replacement of the affected sensor.
11.1 Maintenance
Before all maintenance work the filter mobile is to be disconnected from the supply voltage, the shut-off valve is to be closed and both fuel lines may not be immersed in liquids.
11.1.1 Water drain
If the filter bowl is filled with water up to the installation level of the water sensor, this filling level is reported over the water indication (red LED on the front panel of the filter mobile). The collected water must be drained off now at the latest.
For a precise description of the procedural method, see:
" Installation instruction SEPAR english.pdf"
11.1.2 Filter change
According to dirt accumulation, the filter element must be changed at regular intervals. Before the change, any water and dirt which are still present in the filter system must be drained off via the drain valve into a suitable container.
For a precise description of the procedural method, see:
" Installation instruction SEPAR english.pdf"
11.1.3 Sensor technology
The water sensor is wear-free and maintenance-free. However, it must be ensured that the sensor surfaces indicate no contamination or damage in order to obtain unambiguous results of measurement. If the sensor should indicate any damage, the sensor must be replaced. Repair is not possible.
11.1.3.1 Dismantling and installation of sensor
Before the sensor removal, the filter is to be emptied completely (see Chapter Filter change). The sensor is bonded in, however, it can easily be removed from the filter bowl with a matching open­end wrench. The removed sensor can now be examined for dirt accumulation and damage. If no fault is detectable, the sensor can be re-installed after cleaning of the sensor and filter bowl (see Chapter
11.2 and 11.311.3).

Willibrord Lösing
Filterproduktion GmbH
The removed sensor is sealed with the enclosed O-ring. The screw thread of the water sensor is coated with a suitable, non-alcoholic and soluble bolt-securing agent (e.g. Delo-ML 5298) and secured against falling out by this. The sensor thus prepared is screwed hand-tight into the filter bowl. The restart of operation may not be implemented until after the complete drying of the bolt­securing agent. The mandatory drying time depends on the employed bolt-securing agent and is to be looked up in the relevant data sheets.
11.2 Filter bowl cleaning
Only clean diesel oil should be employed for the cleaning of the filter bowl.
For a precise description of the procedural method, see:
" Installation instruction SEPAR english.pdf"
11.3 Water sensor cleaning
After removal, the water sensor can be cleaned with a soft cloth. In the case of fixed-adhering contamination, a non-alcoholic, standard household cleaner may be applied with the cleaning cloth. The cleaning agent must be completely removed after that. The water sensor may not be employed until after complete drying, as described in Chapter 11.1.3.1.
The employment of sharp cleaning tools or sharp and peaked objects can lead to damage to the sensor surfaces and therefore must be avoided.
