1. GENERAL INFORMATION
1.1 SAFETY PRECAUTIONS & GENERAL WARNINGS
Installation, operation and servicing of the SEV
should only e performed y qualified
personnel. Before installing the SEV package,
the " uick Start Guide" should e read,
understood, and all safety precautions
mentioned in these documents and warnings
must e followed. The SEV must e installed
according to the descriptions in this technical
manual 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 smart servo electronic valve has een integrated with a pressure and temperature sensor
alongside a flow meter. The intelligent design has een further improvised y removing some adjustments to
simplify and quicken the set-up process. Integration of pressure and temperature sensors ena le excellent
ride quality y providing real time compensation to pressure and temperature changes.
The smart electronic card: The on oard we server and Wi-Fi on the electronic card allows users with any
Smart phone, Ta let, Laptop or PC having Wi-Fi connection possi ilities to connect with the card and set-up
the system, make changes or even see the travel graphs of the elevator. The platform is system independent
and can e accessed using any standard we rowser independent of the operating system of the device used
for interacting with the card. The Wi-Fi connectivity makes it very easy to use any smart device for set-up, fine
tuning and real time monitoring from a distance without the hassle of using different ca les and compati le
devices in a machine room. Since the complete system is platform independent, there is no need to download
and install any app or software. The em edded software on electronic card stores all the settings, information
and travel logs. The set- y-step set up guide and multilingual interface software in SI and Imperial units make
inputting and monitoring information very easy.

2.1 LED DIAGNOSTICS
SWITCH LED
If switch “1” is in „ON“-
position, the LED will
flash slowly. Once a
connection to a smart
device is esta lished,
the LED glows
continuously.
POWER LED
The green power LED
will continuously glow
as long as the
electronic card is
supplied with power.
INPUT AND OUTPUT SIGNAL LEDs
D (red), C (red), B (green), A (green) and Ins
(yellow) are reflecting the input signals into
the electronic card.
Down (red) and Up (green) are the
corresponding output signals and indicate the
travel direction.
BOOT LOADER LEDs
If the jumper is set in
non- ridged mode, the
green and red LED will
light up alternately.
Setting the jumper in
ridged mode causes
the red LED to glow
continuously and the
green LED to flash
slowly. If an update is
eing processed, the
green LED will flash
rapidly until the update
is finished.
Green
Red
STATE LED
The orange state LED flashes
slowly. Any other ehaviour is
related to communication
pro lems and reflects a defect.
FLOW LEDs
They indicate if the
sensor has een
adjusted properly. If
the adjustment is set
higher or lower than
the range, the
corresponding LEDs
will light up to signal,
that the sensor has to
e readjusted.
SENSOR LEDs
These will glow green if
the pressure-
temperature sensor is
connected properly.
Orange
Red
DIAGNOSTIC LEDs
The orange “Warning”
LED lights up in case
of an unexpected
ehaviour. If there is a
major fault interfering
with the normal
operation of the valve
like the flow sensor or
a coil eing defect, the
“Error” LED will light
up and prevent the
SEV from functioning
until the error has
een quit with the help
of the “OK” utton.

3. THE SEV VALVE
The Blain Servo Electronic Valve (SEV) is controlled y closed loop digital electronics, providing
consistent acceleration and deceleration of hydraulic elevators largely independent of load and
oil temperature. An electronic card regulates the performance of the car via proportional solenoid
valves. The elevator operation can e monitored, recorded and adjusted y a smart device using
Wi-Fi connectivity. Additional intermediate speed for maintenance runs can also e programmed.

3.1 VALVE OPERATION
UP operation
1. With an Up signal, the pump-motor is energized and the electronic card´s Up program starts
simultaneously. Oil flows through orifice 2 into the ypass pilot cham er UC.
2. Coil A is energized and solenoid A (normally open) from the card and partially closes, reducing
the volume of pilot oil flowing out from the ypass pilot cham er.
3. The ypass valve U egins to close as pressure increases in the ypass pilot cham er. As the
ypass valve U closes, the check valve V egins to open as a steadily increasing volume of oil
flows into the cylinder of the elevator, displacing the flow meter .
4. The inductive flow sensor I, measures the increasing displacement of the flow meter. This value
is compared in the card with the target flow value, which prescri es the acceleration, full speed,
deceleration and levelling speed of the car. Correction of the measured flow rate is made y
varying the power from the card to coil A, controlling the position of the ypass valve through
pilot pressure in cham er UC.
5. The comparison and correction of the measured flow to target flow values, continue throughout
the complete Up operation of the elevator.
DOWN operation
(Caution! Voltage for coil D comes directly from the elevator´s controller, not from the SEV
card)
6. With a Down signal, coil D is energized, solenoid D (normally closed) opens and the electronic
card´s Down program starts simultaneously.
7. Coil C is energized from the card and solenoid C (normally closed) partially opens allowing oil
to pass through fixed orifice 8 escaping from the down valve pilot cham er XC through solenoid
D (fully open) ack to tank.
8. The down valve X egins to open as pressure decreases in the down valve pilot cham er XC.
As the down valve opens, a steadily increasing volume of oil flows from the elevator´s cylinder
into the tank, displacing the flow meter .
9. The inductive sensor I measures the increasing displacement of the flow meter. This value is
eing compared y the card with the set value of the target flow.
10. Correction of the measured flow rate is made y variation of power from the card to coil C
controlling the position of the down valve through pilot pressure in cham er XC.
11. The comparison and correction of the measured flow to target flow values continue throughout
the complete Down operation of the elevator.

Inspection Speed
Besides full speed and levelling speed, an optional inspection speed is included in the electronic
card´s software. Up and down inspection speeds can e independently adjusted etween 0.05 m/s
and 0.30 m/s.
Valves are already adjusted and tested. Check electrical operation efore changing valve settings.
Test that the correct coil is energized y removing the nut and raising the coil slightly to feel magnetic
pull.
S Pressure relief valve: Turning it ‘In’ (clockwise) produces a higher, ‘out’ (c-clockwise) a lower
maximum pressure setting. After turning out, open manual 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 must e de-energized! The KS is adjusted with a 3 mm 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 empty car just egins to descend, then
turn out another half a turn to ensure that with cold oil the empty car can e lowered as required.

6. FLOW SENSOR AND SOLENOID ADJUSTMENTS
Adjustment of solenoid power levels A and C (already factory adjusted)
The adjustment of the solenoid power level is necessary if parts of the solenoids have een changed during
servicing. Solenoid power level has to e adjusted to ensure the valves est possi le performance and to
produce a quick and smooth initial movement of the car away from the floor. The travel direction is shown y
the color of the LEDs. Green LEDs are referring to Up direction while red LEDs are used for Down direction.
The “MAIN MENU” and the “Status” are
showing the digital value of the UP solenoid
(A) or DOWN solenoid (C) during an UP or
DOWN travel. Depending on travel direction,
the green LED for output signal A (Up) or red
LED for output signal C (Down) will e
illuminated. The digital value should e
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 more time for
adjusting. To alter the value, turn the trim
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 should only e necessary when replacing sensors.
Vertical sensor adjustment
If the sensor value [mA] under static condition is not etween 4,8 and 5,3 mA, close the all valve and open
manual lowering to make the valve pressure-less, loosen up the lock screw of the sensor and turn the
knurled sensor-head in or out until the value is etween 4,8 and 5,3 mA. Re-tighten the lock screw.
Adjusting the sensor value elow 4.5 mA may cause the sensor to
press against the flow meter .
Radial sensor adjustment
For radial adjustment of the sensor loosen the ushing lock
nut (4), without turning the sensor ushing (2). Operate the
elevator to run Up and Down at leveling speed. Measure
the speed with stop watch or tachometer. Levelling speeds
for oth directions should have the same value. If Down
leveling speed is slower than Up leveling speed, rotate the
ushing (2) clockwise y 15° and re-measure the leveling
speeds. If Down leveling speed is faster than Up leveling
speed, rotate the ushing (2) counter-clockwise y 15° and
re-measure the leveling speeds.
Repeat the process of rotating the ushing in clockwise or
anti-clockwise as required to set the Up and Down leveling
speeds to e practically the same. Re-tighten the ushing
lock nut once the setup is finished.

for possi le updates.
The “Access” utton gives the user the possi ility to enter and change
passwords necessary for accessing the features of the software.
Furthermore the “MAIN MENU” acts as the first tool for analyzing and
setting up the valve. Values for pressure, temperature and flow are
displayed. In case of no readings the connections need to e
rechecked or the sensors changed. LEDs for input and output give
feed ack 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 marks should show up ehind the digital
values of the solenoids giving feed ack of the correct starting values.

Enter the pump performance data
provided y the manufacturer. Due
to changes in load and oil viscosity
the pump will not always deliver its
full flow. Furthermore some flow is
needed y the SEV to regulate and
provide constant speed and travel
time. 90 % efficiency is an
approximated value.

Provide the static weight of your
elevator system and the pay load
data. Alternatively the values for
minimum and maximum pressure
can e entered. Please note that
entering the weight would
automatically calculate the pressure
and vice versa.
←Left and Right→
Enter your desired speeds,
acceleration and deceleration times
of the Up travel as well as the Down
travel.
Your full speed in Up direction is
already eing calculated ased on
the entered piston and pump data.
Speed in Down direction is limited to
196,85ftm (1m/s). Values shown in
imperial units are displayed after
eing converted from Metric system
and therefore vary slightly from the
input value.
The soft stop setting controls the
final stopping into the landing zone
in the Up direction. Making it too soft
which means choosing a smaller
value may cause the elevator to
continue traveling and surpassing
the floor level.
