1. Use of the product
The digital electronic control unit is designed to control single or double solenoid hydraulic valves in a open control loop without feedback. The
advantage is a miniature design in the form of DIN connector plug and easy mounting on the valve. The ECU for single solenoid valve is simply
mounted on the socket of connector EN 175301-803-A of solenoid coil. The ECU for double solenoid valve is connected to the connector plug of
the second coil with a cable. A five-pin connector with the thread M12x1 is used for voltage supply of ECU in the range 9 …. 32 V DC and a
transfer of input command signal. Parameter setting, such as selecting the type of input command signal, setting the ramp function or PWM
frequency of output control signal, is performed via Bluetooth in the application designed for installation on android and iOS. The application also
enables parameter monitoring, which is advantageous especially in installing or servicing the equipment. The coil control with PWM signal reduces
energy consumption, coil heating, hysteresis and increases the control accuracy.
The electronics is marked with the CE mark of conformity and a Decleration of conformity is issued for it.
The manufacturer provides a warranty period of 1 year for electronics. However, the right to make a complaint may not be accepted by the
manufacturer if the electronics are mechanically damaged or incorrect use of the product which is not in accordance with these operating
instructions has been proven.
2. Risks and restrictions of product use
Danger!
The electronics are designed to be supplied with a DC voltace in the range of 9 – 32V DC, do not connect the electronics to AC
voltage of any value or to DC voltage outside the permitted range. There is a risk of product destruction, damage to health or
property and fire.
Caution!
The maximum ambient temperature for operation of the electronics is -40 °C … +80 °C
Warning!
Argo-Hytos s.r.o. does not bear any responsibility for damage caused by incorrect use of the electronics or activities that are
in conflict with this instruction manual.
