RACO-EPS - Electronic Position System

EPS 02

The RACO positioning system has been designed especially for positioning electromechanical actuators for carrying out linear movements. In this case, position is not mapped using the classical electromechanical method, rather it is realised inductively through magnetic field coupling.

The EPS position sensor consists of a printed circuit board and a magnetic holder with magnet. The EPS electronic position sensor is integrated into additional device housing A at the second end of the motor shaft of the RACO servomotor or into additional device housing D on the clutch housing. Compared to a classic design with mechanical limit switches and an individually adaptable manual transmission, the installation, commissioning, maintenance and upgrade are simplified.

The basic version EPS02 enables the monitoring of end positions by means of 2 adjustable relay contacts in teach-in mode. The end positions are not traversable and therefore provide a high degree of operational safety.

Technical Highlights of the EPS 02 Sensor

  • non-contact, wear-free sensor system
  • digital resolution < 0.01 mm
  • battery buffering in the case of a power failure (service life >10 years)
  • integrated evaluation of thermal contact / PTC thermistor sensor
  • switching points adjustable in the teach-in

EPS 06 with analog Feedback

With the RACO EPS 06 position sensor, additional functions have been integrated into the tried and tested RACO position sensor. With an additional interface board, space has been created for further analogue and digital outputs and additional functionality.

In addition to the 2 end position monitoring systems (relay contacts), there are now 4 adjustable intermediate positions available, calibratable analogue position feedback and an electronic overload protection (RPM function) with adjustable time for start override and speed ​​shut-down. Effective in both directions and locking in overload direction

The parameterisation is carried out by means of an intuitive Windows PC program. The connection is made via the USB cable supplied. The software is used for the diagnosis and parameterisation of the switching points and function.
