•
Loosen the two lock nuts for the adjustment work and turn the two set screws (3) M12x60
DIN 913 in the lever approx. 2 turns counterclockwise.
•
Turn the screw (6) into the lever until it touches the tip of the plunger. Now adjust a small
clearance of 0.2 to 0.4 mm on both sides between the friction blocks and the brake disc
by turning the screw (6) further, whereby the friction blocks must not grind. It is advisable
to press a friction block against the brake disc and adjust the required total clearance by
means of a feeler gauge on the opposite friction block.
Tip!
The adjustable minimum clearance depends on the lateral run-out of the brake disc.
The lower the clearance, the greater the wear reserve before the brake caliper has
to be adjusted.
Depending on the position of the brake caliper and the brake disc axle, the laterally mounted
electromagnet can generate a tilting torque, which causes an uneven air gap between the two
friction blocks and the brake disc. In extreme cases, a friction block can even come into contact
with the brake disc and the entire clearance is set at the opposite friction block.
The result would be a constant rubbing of this friction block during operation. The air gap can be
evenly adjusted by means of the set screws (3). Determine which friction block has the larger air
gap. Turn the set screw on the lever clockwise and adjust an even air gap of 0.2 - 0.4 mm on
both sides.
Important:
It must be ensured that the friction blocks (2) do not rub against the brake disc when
the brake caliper is open.
Important:
If the brake is released by screwing on the "Emergency release nut" pos. 8, the
hexagon nut must be removed for a functioning brake after installation of the brake!
If the power supply of the brake is switched off, the full braking torque (holding torque) is
available.
8.5 Connecting the signal cable of the friction block (option)
Connect the signal cable to a 24V control voltage, e. g. via a signal lamp. If the maximum
permissible friction lining abrasion limit is reached, contact to the neutral conductor is made and
the signal lamp lights up.
