Lodar PWM Soft Control Fed up with truck beds banging and winch cables snatching? For those of you ordering a new truck, you should consider upgrading to a higher specification of radio control. It costs less than you think. See the video – Lodar.com
suitable valves would be Youli PV4, Sauer Danfoss PVE, Bucher HDM/HDS15, and certain Hydro-Control EX Series. There are other valves as well.
-RADIO CONTROLThere are 12 x PWM outputs and a non-PWM Master Output. All systems are fully wired with a Deutsch Connector. The relevant software, which can be downloaded from the Lodar website, is easy to use. Connectivity is through a socket on the Receiver, direct to the computer.
Unlike normal PWM systems where there is full, variable control from the Transmitter, Lodar uses their normal Transmitter with a Receiver that is Pre-Programmed. This important feature allows each function to be set as required. It is only the first few seconds (at the beginning and end of each function) that is “softened,” removing the harsh actions of momentary systems.
TECHNICAL INFORMATION -VALVESLodar PWM Soft Control has already been fitted to vehicles, using P70CF, Hydro-control EX38, and Walvoil DPC130. Other
The Flow Control Valve will have the following adjustments: 1. Dither Frequency & Dither Amplitude. 2. PWM Threshold – the level at which the valve just starts to move. 3. PWM Top Limit – the desired maximum level to which the valve may open. 4. Start Ramp Time – the time taken for the valve to travel between the Threshold and the PWM Start Level. 5. Stop Ramp Time – the time taken for the valve to travel between the Set Level and the Threshold. 6. PWM Start Level – the start-position of the flow (speed of the conveyer). 7. PWM Step Size – the percentage increase or decrease the valve moves when conveyor speed is adjusted. The Directional Control Valve will have the following adjustments: 1. Dither Frequency & Dither Amplitude. 2. PWM Threshold – the level at which the valve just starts to move. 3. PWM Top Limit – the desired maximum level to which the valve may open. 4. Start Ramp Time – the time taken for the valve to travel between the Threshold and the Top Limit. 5. Stop Ramp Time – the time taken for the valve to travel between the Top Limit and the Threshold.
FLOW-SHARING VALVE BLOCKS The PWM software cannot alter the interlocks that are set as standard; it just controls the PWM valves. If you want to activate more than one function at a time (a useful feature), you need to have the interlocks set up accordingly when ordering the Receiver. 888-685-6327 www.LodarUSA.com 12
