1. GENERAL INFORMATION
1.1 SAFETY PRECAUTIONS & GENERAL WARNINGS
Installation, operation and servicing of the SEV
should only be perfor ed by qualified
personnel. Before installing the SEV package,
the "Quic Start Guide" should be read,
understood, and all safety precautions
entioned in these docu ents and warnings
ust be followed. The SEV ust be installed
according to the descriptions in this technical
anual and in accordance with the local
elevator safety codes and directives.
1.2 PRODUCT INTRODUCTION
The SEV package consists of:
1) SEV valve,
2) Electronic card,
3) User Manual.
The valve: The s art servo electronic valve has been integrated with a pressure and te perature sensor
alongside a flow eter. The existing design has been further i proved by re oving so e adjust ents to
si plify and quicken the set-up process. Integration of pressure and te perature sensors enable excellent
ride quality by providing real ti e co pensation to pressure and te perature variations.
The smart electronic card: The onboard web server and Wi-Fi on the electronic card allows users to connect
with the card using any s art device (phone, tablet, laptop or PC). Setting up the syste , aking changes or
observing travel graphs of the elevator are possible via Wi-Fi connectivity. The platfor is syste independent
and can be accessed using any standard web browser independent of the operating syste of the device used
for interacting with the card. Since the co plete syste is platfor independent, there is no need to download
and install any app or software. The e bedded software on electronic card stores all the settings, infor ation
and travel logs. The step-by-step set up guide and ultilingual interface software in SI and I perial units ake
inputting and onitoring infor ation very easy and accessible.

3. THE SEV VALVE
The s art Servo Electronic Valve (SEV) is controlled by closed loop digital electronics, providing
consistent travel characteristics elevators irrespective of load and oil te perature variations. An
electronic card regulates the perfor ance of the car via proportional solenoid valves. The elevator
operation can be onitored, recorded and adjusted by a s art device using Wi-Fi connectivity.
Additional inter ediate speed for aintenance runs can also be progra ed.

3.1 VALVE OPERATION
UP operation
1. With an Up signal, the pu p- otor is energized and the electronic card´s Up progra starts
si ultaneously. Oil flows through orifice 2 into the bypass pilot cha ber UC.
2. Coil A is energized and solenoid A (nor ally open) partially closes, reducing the volu e of pilot
oil flowing out fro the bypass pilot cha ber.
3. The bypass valve U begins to close as pressure increases in the bypass pilot cha ber. As the
bypass valve U is closing, the check valve V is opening while a steadily increasing volu e of oil
is flowing into the cylinder displacing the flow eter Q.
4. The inductive flow sensor I, easures the increasing displace ent of the flow eter. This value
is co pared in the card with the target flow, which prescribes the acceleration, full speed,
deceleration and levelling speed of the car. Correction of the flow rate is ade by varying the
power to coil A fro the card, controlling the position of the bypass valve through pilot pressure
in cha ber UC.
5. The co parison and correction of the flow continue throughout the co plete Up operation of
the elevator.
DOWN operation
(Caution! Coil D is directly connected to the elevator´s controller, not to the SEV card!)
6. With a Down signal, coil D is energized, solenoid D (nor ally closed) opens and the electronic
card´s Down progra starts si ultaneously.
7. Coil C is energized fro the card and solenoid C (nor ally closed) partially opens. Oil escapes
fro the down valve pilot cha ber XC through solenoid D (fully open) back to the tank, while oil
passes through fixed orifice 8 fro the cylinder into the down valve pilot cha ber XC.
8. The down valve X begins to open as pressure decreases in the down valve pilot cha ber XC.
As the down valve opens, a steadily increasing volu e of oil flows fro the elevator´s cylinder
into the tank, displacing the flow eter Q.
9. The inductive sensor I easures the increasing displace ent of the flow eter. This value is
being co pared by the card with the set value of the target flow.
10. Correction of the flow rate is ade by varying the power to coil C fro the card, controlling the
position of the down valve through pilot pressure in cha ber XC.
11. The co parison and correction of the flow continue throughout the co plete DOWN operation
of the elevator.

INSPECTION Speed
Besides full speed and levelling speed, an optional inspection speed is available by the SEV syste .
Up and down inspection speeds can be independently adjusted between 0.05 /s and 0.30 /s.
Initial Operations
Valves are already adjusted and tested. Check electrical operation before changing valve settings.
Test that the correct coil is energized by using etal parts to feel agnetic pull. Once syste is
installed correctly, it is ready for operation. Hints:
 Pressure relief valve S:
Turning it ‘In’ (clockwise) produces a higher, ‘out’ (c-clockwise) a lower axi u pressure
setting. After turning out, open anual lowering H for an instant to release pressure inside the
valve.
Important: When testing the pressure relief valve, do not close ball valve sharply.
 KS Slack rope valve:
Coils C and D ust be de-energized! The KS is adjusted with a 3 Allen key. Turning the
screw K ‘in’ results in a higher pressure setting and ‘out’ in a lower pressure setting. To adjust,
turn K all the way ‘in’, then turn K ‘out’ until the e pty car just begins to descend, then turn out
another half a turn to ensure that with cold oil the e pty car can be lowered as required.
UP
When an up call is given, the car ay delay a few seconds whilst the pilot pressure cha ber
UC fills with oil.
 Adjust ent 1 – Bypass (SEV05 only)
With no load in the car, disconnect the SEV card (no power to coil A) and turn on the pu p-
otor. Turn adjust ent 1 ‘in’ until the car barely oves, then turn ‘out’ so the car stands. Turn
‘out’ another half a turn.
DOWN
 Adjust ent 7 – Maxi u speed li itation
Li it the down fast speed in case of wrongly entered technical data being progra ed into
the card to avoid a possible overspeed of the car. For fine tuning, as the elevator reaches the
full speed, No 7 can be turned in until the vibration of the down valve is felt, then turn No 7 half
a turn out.
 Adjust ent 9 - E ergency Down Speed
With no load in the car, turn No 9 in until it is 5 away fro the flange face. Open the
anual lowering H. Turn No 9 out until the speed of 3 c /s (6 ft/ ) is reached. The elevator
travels at the speed of adjust ent No 9 as the anual lowering knob is opened or when coil D
is energised. Levelling speed should be between 5 – 7 c /s (10 – 14 ft/ in).
Adjust ent 9 is the lowest speed to be controlled by the electronic card. Therefore it should be
adjusted lower than the levelling speed.

6. FLOW SENSOR AND SOLENOID ADJUSTMENTS
Adjustment of solenoid power levels A and C (already factory adjusted)
The adjust ent of the solenoid power level is necessary if parts of the solenoids have been changed during
servicing. Solenoid power level has to be adjusted to ensure the valves best possible perfor ance and to
produce a quick and s ooth initial ove ent of the car away fro the floor. The travel direction is shown by
the color of the LEDs. Green LEDs are referring to Up direction while red LEDs are used for Down direction.
Within the “MAIN MENU” and the “Status”, the
digital value of the UP solenoid (A) or DOWN
solenoid (C) during an UP or DOWN travel is
displayed. Depending on travel direction, the
green LED for output signal A (Up) or red LED
for output signal C (Down) will be illu inated.
The digital value should be around 2100 ± 200
during constant travel while in full speed or
slow speed. Setting up this value is easier done
while travelling with slow speed since there is
ore ti e for adjusting. To alter the value, turn
the tri screw in or out. Turn clockwise to
increase digital value. Turn counter clockwise
to decrease digital value.
Adjustment of flow sensor
Attention!
Flow sensor is already factory adjusted. Readjusting is only necessary when replacing sensors.
Vertical sensor adjust ent
If the sensor value [ A] under static condition is not set between 4.8 and 5.3 A, close the ball valve and
open anual lowering to drop the valve pressure, loosen up the lock screw of the sensor and turn the
knurled sensor-head in or out until the value is between 4.8 and 5.3 A. Re-tighten the lock screw.
Attention: Adjusting the sensor value below 4.5 A ay cause the
sensor to press against the flow eter!
Radial sensor adjust ent
For radial adjust ent of the sensor loosen the bushing lock
nut (4), without turning the sensor bushing (2). Operate the
elevator to run Up and Down at leveling speed. Measure
the speed with stop watch or tacho eter. Levelling speeds
for both directions should have the sa e value. If Down
leveling speed is slower than Up leveling speed, rotate the
bushing (2) clockwise by 15° and re- easure the leveling
speeds. If Down leveling speed is faster than Up leveling
speed, rotate the bushing (2) counter-clockwise by 15° and
re- easure the leveling speeds.
Repeat the process of rotating the bushing in clockwise or
anti-clockwise as required to set the Up and Down leveling
speeds to be practically the sa e. Re-tighten the bushing
lock nut once the setup is finished.

software installation on the s art device is necessary. This unique feature allows the user to use any s art
device; independent of the operating syste or software architecture. It is reco ended to use Mozilla
Firefox for Android or Safari for iOS as web browsers.
Before the installation wizard is started it is highly recommended that all technical data of the lift is readily
available and that the input unit is correctly selected. The choice for unit’s selection between Metric and

The “MAIN MENU” allows access to the “Install wizard”, the “Data
collection”, the “Settings” and the “State/notifications” sub enus.
The “Install wizard” is being used to assist during valve setup and
serves as a step by step guide to help users entering the co plete and
correct necessary elevator data.
The “Data collection” gives an overview about all entered data to ake
changes if necessary and it gives access to the “Logboo ” and the
“Trouble shooting” sections.
In the “Settings” enu you can change units, valve and Wi-Fi settings
or reset settings to factory settings if desired.
The “State/notifications” shows the status of the syste and allows for
possible updates.
The “Access” button gives the user the possibility to enter and change
passwords necessary for accessing the features of the software. Only
with correct access changes can be ade.
Further ore the “MAIN MENU” acts as the first tool for analyzing and
setting up the valve. Values for pressure, te perature and flow are
displayed. In case of no readings the connections need to be rechecked
or the sensors changed. LEDs for input and output give feedback for
diagnostics.
While traveling constantly in full speed or levelling speed in Up or Down
direction, the highlighted digital value should stay in the range of 2100 ±
200. The green check arks should show up behind the digital values
of the solenoids giving feedback of the correct starting values.

←Left
Enter the pu p perfor ance data
provided by the anufacturer. Due
to changes in load and oil viscosity
the pu p will not always deliver its
full flow. Further ore so e flow is
needed by the SEV to regulate and
provide constant speed and travel
ti e. 90 % efficiency is an
approxi ated value.
Right→
Provide the static weight of your
elevator syste and the pay load
data. Alternatively the values for
ini u and axi u pressure
can be entered. Please note that
entering the weight would
auto atically calculate the pressure
and vice versa.
←Left and Right→
Enter your desired speeds,
acceleration and deceleration ti es
of the Up travel as well as the Down
travel.
Your full speed in Up direction is
already being calculated based on
the entered piston and pu p data.
Speed in Down direction is li ited to
196,85ft (1 /s). Values shown in
i perial units are displayed after
being converted fro Metric syste
and therefore vary slightly fro the
actual value.
The soft stop setting controls the
final stopping into the landing zone
in the Up direction. Making it too soft
(choosing a s aller value) ay
cause the elevator to continue
traveling and surpassing the floor
level.
