Setting the movement forces in the idle state

The maximum set brake force occurs in the idle state. This means that the brakes are not
released, the ARCOSKOP is switched off, the system has been disconnected from the
power supply, for example system emergency shutdown or no compressed air is present
in the system.
In order to adjust this max. set brake force it is necessary in each case to remove the
upper brake unit including compressed air bellows with the aid of a 17 mm offset ring
wrench.
NOTE
•
Pump the brakes several times to let the compressed air exhaust from the system.
•
For this purpose remove the compressed air connection, remove the locking nut and
brass bush and remove the upper part. Pay attention to the slot of the brass bush,
because this must fit the nub again on assembly (see Fig. 7 and Fig. 8).
•
The brake force is set with a 17 mm offset ring wrench on the internal nut inside the brake
plate, see Fig. 8.
•
Reinstall the previously removed brake plate in the support arm. Pay attention to the
correct position of the nub in relation to the slot. Fasten the brake plate loosely with an
offset 17 mm ring wrench. Around 2 mm play are necessary for operation of the brake.
•
Check the brake force with brakes released, refer to "Setting the movement forces in the
working condition" in this chapter.
•
Reinstall all covers.
