Failure to properly center the brake and obtain uniform lining contact results in localized heating and, ultimately, reduced torque, which can cause injury or death.
Chapter 6: ADJUSTMENT – Warnings and Cautions
Protect against the possibility of movement due to the effects of gravity, wind or other source of energy, which has the potential to create a hazard when the brake is being worked on or is removed entirely.
If the brake is arranged to operate in manual mode, the actuator “reserve stroke” must be monitored and adjusted to be within the range of 30 to 35% of full stroke with the brake applied.
An actuator reserve stroke of zero will result in total loss of brake torque.
Under no circumstances should the brake be allowed to function with zero reserve stroke. Such operation results in loss of load control, which can result in injury or death.
Always replace the caps on the actuator once adjustments are complete. This will prevent entry of contaminants.
The optional automatic adjustment mechanism uses a
If it is necessary to use a wrench to adjust the reserve stroke of a brake with
The two setscrews used to lock nut (F), see Fig. 2A, to the clutch drive shaft, are factory set. Do not loosen these setscrews or change the position of nut (F) with respect to the assembly. Failure to observe this warning can cause the automatic adjustment feature to become inoperative. This can lead to loss of load control and result in damage, injury or death.
Chapter 7: ELECTRICAL DETAIL – Warnings and Cautions
The actuator motor must be connected to its supply through a flexible cable or sealed flexible conduit. This is required to ensure that contaminants will not enter the motor through the wiring and junction box.
