The brake with the retainer ring can be clipped onto the pointer cylinder independently of the
built-in components (ESK2A, limit switch, counter). When installing the brake, note that the slit
between the brake magnets is only about 3 mm and the material thickness of the aluminium
pointer vane is 1mm.

• Clip on Eddy current brake 1.
• Turn brake slightly in a clockwise direction 2.
• Check that the pointer vane can be moved between the magnets without touching them.
• Screw in turnbuckle 2.

• Remove counter module (if available).
• Loosen the locking screw 2 on the contact pointer.
• Merge contact pointer 1 in the middle.
• Insert the contact module into the third slot of the bracket until the semi-circle 3 surrounds

the pointer cylinder.

The contact module connecting terminals feature a pluggable design and can be removed in
order to connect the cables.
