Brake Wiring
•
Connect the machine brake and emergency brake as shown.
•
The brake switches are wired normally closed from HWEC.
•
To change the switches to function as normally closed, remove the blue wire from the
terminal block in the electrical enclosure, and replace it with the spare gray wire coming
from the brake switch.
Brake Adjustment/Centering
Brakes must be adjusted after load is applied to the machine.
As brake pads wear, or new pads are installed, adjustment will be required.
Adjustment of the Stroke
The air gap of the brake is the space between the braking pad and braking wheel. The aim of
adjustment of the air gap of brake, is to adjust the space between the braking pad and the
braking
wheel. Correct air gap is between 0.012” (0.30 mm) to 0.022” (0.55 mm).
