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.
