1 Technical Data
1.1 Functional description
The control unit EBC 3000 was developed to operate the RNA mini-band conveyor FP 15. The applied pulse width
modulation generates high efficiency and good start-up characteristics through a near 1 form factor. All operating controls
including the plug-in device for the motor connection are arranged on the front panel.
A switched-mode power supply in accordance with VDE 0551 generates the operating voltage of max. 24 volts for the belt
drive, so the motor voltage is a
contact-safe protective extra-low voltage.
An internal current scanning (I x R compensation) equalizes speed fluctuations when the load on the conveyor belt
changes.
* Minimum and maximum output voltage, U
min
und U
max
, as well as maximum motor current, I
max
, are continuously
adjustable on the board.
* The conveyor belt can be powerlessly started and stopped over additional wiring.
* In addition, one can regulate the target value over an external 0-10V or 0-20mA signal.
* Over a voltage-free contact, one can reverse the sense of rotation of the connected motor.
* The control unit is designed for a mains voltage from 110 volts AC to 230VAC. The control unit checks the mains voltage
and adjusts itself automatically.
