Preparation for installation
Before mounting on the 12.5 mm thick brake disc, the brake must be released (opened). This is
possible:
with the aid of the electromagnet, provided that it is already connected to a power source (see
Section 8.5)
mechanically, by loosening the lock nut and turning the screw (6) clockwise into the lever and
thus increasing the clamping gap between the friction blocks.
Important!
Check whether the brake disc can rotate freely.
Important!
If you have loosened the screw (6) for installation, you must carry out all steps
8.4 for a fully functional brake calliper after installation!
8.3 Electrical connection of the brake caliper
Caution! Danger of damage!
Before connecting the brake caliper to the power supply, check that your power
supply corresponds to the specifications for rated voltage and mains frequency on
the nameplate. In case of deviations, never connect the brake caliper, as otherwise
the electronics or electromagnet of the brake caliper will be destroyed.
Nominal voltage: 110 .. 120 VAC or 230 .. 240 VAC depending on the electromagnet,
50/60 Hz, single-phase.
Line protection : 6 A,
has to be ensured by the user!
When switched on, currents of up to 3 A occur for 0,7s. After that the current is about 0,6 A.
The brake caliper is actuated by switching the supply voltage on and off.
On the electronics there is a free-wheeling diode which suppresses a switch-off overvoltage when
the supply voltage is switched off.
A transformer may be used for voltage reduction if its power rating is at least 0.3 kVA.
There are two ways to connect the supply voltage:
