Young Powertech is a Manufacturer and Distributor of High
Quality Electronic Radio Remote Controls and Joysticks. Our Electronic Radio Remote Controls and Joysticks can be used in hundreds of Apllications and Industries around the world. Below is a list of the the types of Electronic Radio Remote Controls Young Powertech Produces and some applications in which they are used for.

Remote Controls:
YRC400 and YRC400 HANDY
YRC400 is an Electronic radio remote control system used to control hydraulic machines. Extremely easy to use, safe, fast and precise; its electronic core, based on advanced microprocessor technology, is highly confi gurable. All parts are protected against electro-magnetic and radio frequency radiation and can be used in the most demanding and roughest environments, for cranes, platforms, power stations, oil platforms and also specific applications.

Hydraulic Modules:
YMOD09 (Dual Control Rods and Distributors)
YIT028 (Hydraulic Pilot Distibutors and Variable Flow Pumps)

The proportional block can be used with a remote control to
drive servo controlled hydraulic machines.

Look at it as a good alternative to add to the control system
currently installed on the machine (ex. hydraulic joysticks on
the driver?s cab).A variation of the command current (PWM) of the coils of the block changes proportionally its fl ow, moving the machine hydraulic distributor.

Since the driver?s cab joysticks of the machine are no more,
the driver can move himself near the machine working fi eld
(ex. to verify that the work is done correctly) or far from it
increasing his safety. It has been designed in modular form allowing the assembly of sections up to 8 functions.
On request it is available an exchange solenoid valve used to
select the working mode of the machine (manual or remote

HANDY DRIVE (Handheld Control System), YMANP (One Axis with Signal outputs), YMANP2 (Two Axis with Signal Outputs), YMANP3 (Three Axis with Signal Outputs), YMAS (One Axis with Signal Outputs), YMAP (One Axis with Power Outputs), YJS, YJP and YJC.

The HandyDrive handheld control system, composed of the handeld remote control and the electronic control unit, is designed to make simple and intuitive the control of an hydraulic driven machine. Moving the mini/joystick on the handle the system controls directly the four PWM outputs for the crawler tracks: left forward/bacward and right forward/backward.

A single or double Dump Valve is also commanded at every movement.

is a single axis electronic joystick with signal outputs
Joystick commands are derived from the measurement of the magnetic field produced by permanent magnets; the measurement is taken through Hall effect probes. This kind of probes are not subject to wear and tear.

Main characteristics:
? sturdiness;
? parabolic output signal for a better sensitivity;
? output signal stroke customizable;
? available with uni directional output (5V-0-5V) or bidirectional output (0-5V-10V);
? ?position hold? hand-grip available;
? rocker switch (unstable) on the hand-grip available;
? on/off directional outputs;
? supplied with extractable connector with screw;
? available version with two separate outputs 0-5V.

Stabilizers Controls:
YSCS (Stabilizers Control Device with Integrated Functions)
The SCS device is a stabilizers control unit integrated with some auxiliary functions useful for the control of cranes installed on trucks. The core of the unit is a microprocessor based electronic card for the advanced control of the machine, which makes available in one device the following features:

BYPASS INTERFACE: control the NO dump valve with a signal compounded of the safety electric signal from the radio remote control and from the torque limiter, maintaining the origin safety characteristics.

The NO valve can be commanded both from the remote control and from safety devices installed on the machine (ex. torque limiter).

STABILIZERS CONTROL: verify the correct position of the stabilizers and, if the platform is inserted, enable the crane to work only when they are all extended and correctly positioned.

STABILIZERS BLOCK: class 3 control that avoids the movements of the stabilizers when the main arm of the crane exceeds the horizontal slope. The stabilizers are blocked with a

NO valve when their distributor is separated from the crane distributor, or with a NC valve when the stabilizers are commanded by the same distributor of the crane.

SPEED REDUCTION: if this function is not executed by the radio remote control, reduce the speeds of the manoeuvres when the platform is inserted on the crane; the speed reduction is realized through a flow reduction valve.

Electronic Regulators:
YVPC (Connector Version), YVPP2 (Panel Version), YVPOL (Octal Socket Version), YVPUD-M (Undecal Socket Version with Double Output), YSTU-PWMi (Electronic Regulator for Multiple PWM Controlled Solenoids) and YCIVP (Proportional Solenoid Incremental Control Device)

This YVPC electronic regulator is made to work in open loop control system. It has been designed to control the current that fl ows in the coil of a solenoid valve proportionally to an analog input
signal. The electronic card is contained in a box that works as connector too.

electronic regulator is designed for single solenoid proportional valve open loop control. Current regulation potentiometer is connected and assembled yet on electronic regulator. Current range (offset and gain), ramps times and PWM frequency can be modifi ed through trimming potentiometer (placed on the back side of card) to meet different kind of valves specifi cations. YVPP2 is protected against supply overtension and polarity inversion. PWM output is protected against short-circuit. Electronic card is epoxy resin protected.

The YVPUD-M electronic regulator is designed to command two proportional solenoids with one reference signal. Solenoids are controlled (PWM) with feedback signal so that linearity between output current and input signal is guaranteed and working is independent from external elements (supply voltage, temperature,
etc.). The working frequency (PWM) is set to 120 Hz but it is adjustable from 50 Hz to 330 Hz).
The regulator can be commanded by a potentiometer (the supply voltage ?5V are present) but 0 to 10V or ? ? ? Vsupply signals can be utilised (coupling with a PLC). Outputs cannot be active contemporaneously, interlocked by a control circuit.
Minimum (BIAS) and maximum (GAIN) currents and rise/fall ramps are independently adjustable. Ramps are adjustable (between 0.1 and 5 seconds) and disabled by a positive signal connected to the proper input terminal. Red LEDs on panel show input signals variation and current variation to the solenoids, signalling if the output circuit is interrupted.
The regulator is protected against voltage reversal and output short circuits.

electronic card is a regulator for proportional solenoid valves, which can drive up to 8 modules (8+8 PWM outputs), starting from analog inputs (input signal range from 0 to 5V). If the
inputs analog signals are generated from potentiometric joysticks, the control card provides a stabilized 5V supply to power them.

Electronics and Accessories:
YPRG2 (Programming Keyboard), YAIS (Serial Adapter for Electronic Card) and YCCS (Salt Spreader Regulation Dashboard)

The PRG2 keyboard is the simplest device that can be used to tune working parameters on the last-generation electronic cards developed by manufacturer. With PRG2 keyboard and the help of the two-digit display mounted on the electronic card to be programmed, or the fl ashing LED on the PRG2, you will be able to scroll all the working parameters and the tune them at will. At the end of the programming phase, it is necessary to save parameters in memory by pushing contemporaneously the PREV and the NEXT buttons, otherwise all the modifi cations will be lost when the device will be turned off.
PRG2 keyboard connector can be plugged in and pulled out from his socket on the electronic card even with the system turned on.
The presence of the programming keyboard will be automatically
detected and the device will go in programming mode. The LED shows, with a series of fl ashes, the current programming step.

The YAIS Serial Interface Adapter is the only medium to connect our electronic devices (STU electronic card and YJS/YJP/YJC joysticks) to a PC for programming, calibration, firmware updating and working parameters monitoring. The communication between the device and PC is supported by SepSim, a Windows application (Win98/Win2K/XP tested). The ?Lite? version of SepSim is provided freely when the device is purchased. With this application a device confi guration can be saved to a file and downloaded into another device.
The application requires a serial port or a USB to
RS232 converter.The program file is self-installing and the application is extremely user friendly. AIS is provided with a 1,80 m [5.9 ft] long serial cable (DB9 male/female).On the right is showed the main page of SepSim.

The SALT SPREADER dashboard is an electronic regulator that allows you to proportionately control and independently set spreading distance and salt quantity, through the regulation of two PWM outputs. There are also 3 more switches for auxiliary functions:
- one to set proportional commands to their max value;
- one to control light system;
- one to control a bidirectional function (A-0-B).

The red led on the front panel provides informations during working mode. The dashboard is provided with cables and DIN connectors for proportional solenoid valves. On the rear side is placed a strong magnet to fix the dashboard into the cockpit.
