Electronic system for automatic leveling of hydraulic props

The microprocessor-based system is responsible for leveling the hydraulic supports based on data from a two-axis tilt sensor and (optional) pressure transducers installed on the supply lines of each actuator. The sensor readings are sent via CAN bus to the control unit, which precisely adjusts the corresponding sections of the proportional valve. The sensor measures the angle of inclination relative to the horizontal plane in two axes within a range of ±45°, allowing the entire structure to be precisely leveled.

Set Includes:

- Microprocessor control unit with CAN bus

- Cable strip for installation connection

- Transducer-accelerometer with attached eye level for manual reading

- Programmer for changing the controller parameters

Electronic controller 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 CONTROLPANEL 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);

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 (CONTROLPANEL ON, );

- an output to control the DUMP VALVE; 

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

Technical specification:

Serial interface adapter for Faber-Com electronic cards.

The AIS Serial Interface Adapter is the only medium to connect all programmable Faber-Com electronic devices to a PC for programming, calibration, firmware update and working parameters monitoring.

The communication between the device and PC is supported by SepSim, a Windows application (XP/Vista/7/8/10 tested). The "Lite" version of SepSim is provided, free of charge.

With this application a device configuration can be saved to a file and downloaded into another device. The application requires a serial port or a USB to RS232 converter (not supplied).

FIP-C Dual-axis CAN-bus Angle Sensor

FIP-C is a sensor that uses only CAN bus interface to give information about dual-axis inclination. The sensor measures the angular inclination with respect to the horizontal plane.
