The functional scope of this controller is specifically aligned to classic web guiding applications.

ekr 500 digital particularly stands out because of its user-friendliness and convenient commissioning and operation.
The compact controller design and the removeable control unit allows comfortable handling even when its is installed in places which are hard to get to.
The clear LC display graphically shows all relevant data including web position, sensor coverage and actuating drive position.

Insensitive to dirt and changes in the transparency of the material

No changes to the measured values through flutter of the web in the sensor scanning area
Compensation for any interference which may be caused by external sound sources or other environmental influences

• Wear-resistant DC motors
• Ball screw spindle drives for a long service life and minimum backlash
• Designed for curved and linear correcting movements
• Various sizes of actuation path, force and speed possible
• Available with position feedback (precise capturing of current actuating drive position), electronic end position switch-off and servo-center position
• Electrical power supply dircetly from the amplifier
• Maintenance Free

The guiding device is the “hand” which the web guiding system uses to make the physical corrections to the web path.

It becomes active if the web position deviates from the set position.

It corrects the web position, moved by the actuator until the desired position has been reached.

The BST eltromat guiding devices are deliverable in different sizes and versions for almost all web widths and applications. A variety of roll versions and coatings are at the disposal for different material types.
