High voltage! Possible damage to the control electronics. ▶ Wire the control electronics only when it is disconnected from the power supply. Overheating! Possible damage to the control electronics. ▶ Adhere to the ambient conditions according to the data sheet. ▶ Do not use free-wheeling diodes in the solenoid cables. ▶ Ensure sufficient ventilation of air. Overloading! Risk of overloading and damage to supply cables in the case of insufficient dimensioning and/or operation with several electrical devices. ▶ Provide current limitation by overload protection. ▶ Select an appropriate rating of power supply unit and cables. Short-circuit! Risk of overloading of and damage to the supply cable in the case of a defect of electrical equipment. ▶ Provide current limitation by means of overload protection.

Electrostatic discharge! 

Risk of damage to components of the control electronics. ▶ Provide equipotential bonding to discharge static voltage from your body. ▶ Work in a safe environment. ▶ Do not use devices that generate or have static discharge in the working environment. ▶ Do not carry out any work on the control electronics in environments that could generate static charges. ▶ Handle the control electronics with care. Do not touch exposed connection pins and sensitive components of the electronics. ▶ Transport and store the control electronics carefully in the original packaging provided for this purpose. Wrong cables! Voltage loss, scorching of cable! Risk of damage to the product. ▶ For solenoid cables up to 50 m long, use cable type LiYCY 1.5 mm2, for position transducer cables, cable type LiYCY 0.5 mm2 shielded. For greater lengths, please consult us.

Scope of delivery

 The scope of delivery includes the digital control electronics VT-VPCD. Accessories such as interface cables and card holders are not included in the scope of supply, but can be ordered separately. See Chapter 7.4 “Recommended accessories“ on page 30.

Performance description The closed-loop control electronics VT-VPCD is part of a control system for the electrohydraulic control of swivel angle and pressure and power limitation of axial piston pumps of type A4VS... with HS4 control as well as axial piston pumps of type A2V... with EO4 control, each fitted with a proportional valve and swivel angle and position transducers for sensing the swivel angle and the valve spool travel. The control electronics VT-VPCD provides all electrical functions required for the control types HS4 and EO4
