SEV User Manual 3. THE SEV VALVE The Blain Servo Electronic Valve (SEV) is controlled by 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. - Page 8 SEV User Manual 1” SEV 1½” SEV 2” SEV Figure 3: SEV valve dimensions Optional Equipment Emergency coil High pressure switch CSA coils Low pressure switch Slack rope valve Ball valve Hand pump HX/MX Auxiliary down valve Figure 4: Hydraulic circuit...

Up operation of the elevator. DOWN operation (Caution! Voltage for coil D comes directly from the elevator´s controller, not from the SEV card) With a Down signal, coil D is energized, solenoid D (normally closed) opens and the electronic card´s Down program starts simultaneously. - Page 11 To adjust, turn K all the way ‘in’, then turn K ‘out’ until the empty car just begins to descend, then turn out another half a turn to ensure that with cold oil the empty car can be lowered as required.

Page 13: Control Valve Installation
Installation of the SEV Card into the Controller The SEV Card can be connected into any standard type hydraulic elevator controller. The power to coils A and C is supplied from the card. Power to coil D is directly provided by the main controller. Page 11, shows the detailed wiring diagram for connecting the SEV card to the elevator controller. -

SEV User Manual 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 been changed during servicing. Solenoid power level has to be adjusted to ensure the valves best possible performance and to produce a quick and smooth initial movement of the car away from the floor. -

“Data collection”, “Settings” and “State / Notifications” will be explained in detail. As the software for interacting with the SEV card resides on the webserver and on the card itself, no additional software installation on the smart device is necessary. This unique feature allows the user to use any smart device;... - Page 18 SEV User Manual The “MAIN MENU” allows access to the “Install wizard”, the “Data collection”, the “Settings” and the “State/notifications” sub menus. The “Install wizard” is being used to assist during valve setup and serves as a step by step guide to help users entering the complete and correct necessary elevator data.
- Page 19 Furthermore some flow is needed by the SEV to regulate and provide constant speed and travel time. 90 % efficiency is an approximated value.

Travel graphs give the customer and the Blain Hydraulics tech support the possibility to run system diagnostics and check for possible problems. On the left there are two examples of travel graphs in this so called “View 1”.

Elevator surpasses the floor level. Errors 3-7 do not have influence on the operation of the elevator. As long as the power supply to the SEV card is maintained, errors will be saved and the red LED will remain illuminated. The error indication can be cancelled one after the other in reversed order of occurrence (last error first) by pressing OK button on the SEV card or by erasing the error messages within the “notifications”... -

View 2 gives a more detailed look into values of the PID Figure 10.3 controller and will be used mainly by Blain Hydraulics tech support for system diagnostics. View 3 shows the pressure and temperature changes during the travel. Each view has the same basic layout and buttons to fulfil the same functions. - Page 28 SEV User Manual Depending on which channel is chosen (1) the scaling (2) will change automatically. Values shown on the Y- axis relate to the SI or Imperial units selected in the “Settings” accessible form the “MAIN MENU”. Pressing the “Back” button (3) results in a return to the view selection. If a cross-sign can be seen at position number 5, then left (4) and right (6) arrows allow to move along the time axis of the graph.
