Scanreco Stabilizers Autoleveling System PASMRC0073

Electronic regulator for PWM controlled, proportional solenoid valves.

STU-PWM 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.

Inputs

- n° 8 analog inputs signals (range from 0 to 5V);

- n° 1 enable input defined as CONTROL PANEL ON;

- n° 2 ENABLE inputs with different operating features;

- n° 1 input to select LOW/HIGH SPEED(optional);

- n° 3 ON/OFF inputs, directly carried to three power outputs;

Outputs

- n° 8+8 PWM outputs, to drive proportional solenoid valves (a pair of outputs for each analog inputs);

- n° 1 DUMP VALVE output drived by all manoeuvres;

- n° 1 FAULT output;

- n. 3 ON/OFF outputs, directly drived by three ON/OFF inputs (max 2.5A);

Features

Adjustable PWM frequency, min/max output currents and rise/fall time ramps. As option, STU-PWM is available with two selectable maximum speed sets (LOW/HIGH SPEED), to operate a different maximum speed in different operating conditions.

It is also available a DUMP VALVE output that is turned on when a manouvre turns on. This output has a programmable delay on switch off, to avoid elevated pressure spikes in the hydraulic circuit.

The control unit provides three ON/OFF input/output to drive directly solenoid valves, starting from low power command signal.

To ensure more safety during working mode, the electronic card provides:

- programmable deadband, electrical stroke and adjustable signal threshold;

- an overall relay, feedback controlled, supply all control unit's outputs;

- three inputs ENABLE signals (CONTROL PANEL ON, ENABLE1 and ENABLE2);

- an output to control the DUMP VALVE;

- an output (FAULT) to drive a warning light or a relay that report errors on analog inputs.
