1)
The braking torque (nominal torque) is the torque effective in the shaft train on slipping brakes with a sliding speed
of 1 m/s referring to the medium friction radius.
For stabilisation of the friction conditions, a run-in process in new condition is recommended.
2)
Once the maximum air gap has been reached, the rotors must be replaced.
However, the brake already becomes louder at an air gap > "a" +0,2 mm.
3)
Referring to the effective braking torque on switch-off from holding voltage (nominal voltage)
4)
Referring to the nominal braking torque on switch-off from 2 times the holding voltage (overexcitation)
The stated switching times can only be achieved using the respective correct electrical wiring. This also refers to the protective circuit
for brake control and the response delay times of all control components. If the brake is operated using overexcitation, the respective
switch-on and switch-off times for overexcitation must be taken into account (inadvertent movements of the elevator cage).
The use of varistors for spark quenching increases the DC-side switching times.
At temperatures of around or under freezing point, condensation can strongly reduce the braking torque. The user is responsible for taking
appropriate counter measures. The customer is responsible for providing a protective cover against contamination caused by construction
sites.
CAUTION
On brake operation with overexcitation, there is a possibility of possibly unpermitted braking torque reduction when the air
gap "a" > maximum air gap.
