Сервисный кейс с тестовым блоком для сервоклапанов без встроенной электроники VT-SVTSY-1-1X

Description Component series 1X Features Service case – Test device with power supply unit and connection cable Test device – suitable for commissioning and service works at hydraulic systems with servo valves without integrated electronics – In case of faulty machine behavior, allows for functional check and error location without disassembly of the servo valve – Voltage supply by means of 9V block battery or 12V power supply unit Product description Test device type VT-SVT-1-1X The test device is suitable for the control and functional testing of servo valves without integrated electronics. The voltage for the test device is supplied by a 9V block battery (not included in the scope of delivery) or optionally by a 12V power supply unit type VT-SVTNT-2-2X/G12. Notice: The test device may only be used by persons who are familiar with the device, the valve and the hydraulic system. With corresponding setting, it will ignore the control signals coming from the system. If safety precautions have been taken on the control side, they are invalidated. For damage caused by the incorrect operation, no liability is accepted. Valve test Connect the connection cable of the power supply unit at socket (6) of the test device or insert the battery. Set the functional switch (1) to "ON" → "Power" LED (8) lights up. In case of battery operation, carry out the battery test: Set the selector switch (3) to "50 mA" Set the command value potentiometer (4) to "–100%" Press the push-button (2) for battery test The test device indicator shows the battery charge in % Select the coil type of the valve with selector switch (3) at the test device. Bring the command value potentiometer (4) into the central position. Use a suitable valve connection cable (see ordering code) to connect test device (socket (7)) and servo valve. (The valve connection cables are wired so that both coils of the servo valve are switched in series.) Slowly rotate the command value potentiometer (4) to the left or right; observe the movement of the motor or the cylinder while doing so. With the servo valve working smoothly, this allows for the sensitive movement of the controlled motor or cylinder into the desired direction or to the desired position. 1 Functional switch 2 Push-button for battery test 3 Selector switch for coil type 4 Command value potentiometer 5 Coil current indication (in %) 6 Socket for power supply unit cable 7 Socket for valve connection cable 8 "Power" LED display Assignment of coils / valve types Rated current per coil Resistance per coil Valve type 5 mA 500 Ω 4WS2E.10-4X 1) 7,5 mA 200 Ω 20 mA 80 Ω 4WS2E.10A-4X 1) 30 mA 40 Ω 4DS1EO2-1X 1) 50 mA 28 Ω 3DS2EH10-2X 1) 30 mA 85 Ω 4WS2EM6-2X/... 4WS2EM10-5X/... 30 mA 100 Ω 4WS2EM6-2X/... 50 mA 80 Ω 50 mA 85 Ω 4WS2EM10-5X/... 1) Not for new applications Type code 01 02 03 04 05 06 07 08 VT-SVTSY-1 – 1X / 1 – – – – / * 01 Service case with test unit for servo valves without integrated electronics VT-SVTSY-1 02 Component series 10 ...
