Important!
The friction linings (2) must not come into contact with lubricant!
11.2 Permissible friction lining wear and replacement of the friction blocks
Life-threatening danger!
Friction blocks may only be changed when the system or the work machine is
stationary!
Important!
When new, the friction lining has a thickness of 12.5 mm. After 4.5 mm of wear or
a residual lining thickness of 8 mm, the friction blocks must always be replaced in
pairs. Only original RINGSPANN friction blocks may be used.
Important!
Before replacing the friction blocks, make sure that the mass held by the brake is
secured against movement, as the brake must be released (opened) to change the
friction blocks.
Important!
Make sure that no electrical voltage is applied to the brake caliper.
Release the brake by switching on the supply voltage. Secure the open position with the
"Emergency release nut" (8). Turn the screw (6) back until the friction blocks can be changed
easily and secure the screw again with the lock nut. After changing the friction block, you must
readjust the braking torque and clearance as described in chapter 8.4.
Important:
If the brake is released by screwing on the "Emergency release nut" (8), the
hexagon nut must be removed for a functioning brake after installation of the
brake!
Finally, the new friction linings must be applied by braking briefly several times so that the brake
can achieve the required braking torque (see chapter 9).
11.3 Emergency release
Open the brake caliper manually
by screwing on the ”Emergency release nut” (8) on the plunger
until you can move the friction blocks on the brake disc.
12. Installing the inductive sensor (option)
Life-threatening danger!
The inductive sensor may only be changed when the system or the work machine
is stationary!
The inductive encoders M12x1 length 65 mm are supplied separately. In the version with sensor
monitoring, a fixture for the inductive sensors is mounted on the brake lever or can be ordered as
an accessory.
Switching function: PNP (closer)
Switching distance:
6 mm flush-mountable
