Description Component series 1X Features Service case – Test device, 24V power supply unit, connection cable and adapter Test device – suitable for the control and functional testing of proportional servo valves with integrated electronics and an operating voltage of ±15 V or +24 V – Simplifies commissioning and troubleshooting in hydraulic systems with proportional servo valves Product description Test device type VT-VET-1-1X The test device is suitable for the control and functional testing of proportional servo valves with integrated electronics and an operating voltage of ±15V or +24V. Operating modes External operation → Looping in of the operating voltage and the command values from the control cabinet to the valve Internal / external operation → Command value presetting via the test device; operating voltage from the control cabinet Internal operation → Operating voltage via a separate power supply unit; command value presetting via the test device Command value presetting via BNC socket → Operating voltage optional 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. Voltage supply The test device can be supplied with +24 V or ±15 V, depending on the operating voltage required by the valve. To this end, the "power selector" change-over switch must be set accordingly before the commissioning. An internal DC/DC converter creates the required auxiliary voltages ±15 V for the internal command value presetting. The "power selector" selector switch amongst others switches the internal reference potential L0 to the relevant, externally applied ground. Spool position "+24 V" → input pin B = reference potential Spool position "±15 V" → input pin C = reference potential Connections Input connector ES (1) and 4 mm input sockets The input connector ES (1) on the left side serves the connection of the connection cable coming from the control or from the control cabinet. Depending on the setting of the operating elements (see operating and display elements), the 4 mm sockets on the left side are directly connected to the pins of the input connector ES (1). So all signals coming from the control can be measured at the sockets. For operation of the test device and the valve, the necessary operating voltages +24 V or ±15 V (depending on the valve type) must be available. If no operating voltage is available yet on the control cabinet side, a corresponding power supply unit can be connected at the input connector ES. Output socket AB (16) and 4 mm output sockets The output socket AB (16) on the right side serves the connection of the valve. The 4 mm sockets on the right side are directly connected with the pins of output socket AB (16). So all signals t
