Brake Basics
1. Ensure that the brake is picking cleanly. With the car set up so that it will not move:
• Manually activate the PM and BR contactors to lift the brake.
• Measure DC voltage between terminals B1 and B2. It should be very close to the pick
voltage shown in your job prints.
• Refer to job prints and adjust pick voltage if necessary.
2. Ensure that, when set, the brake is capable of holding 125% of rated car capacity. Refer
to Adjust Brake to 125% of Full Load on page 2-83.
3. Check that brake and motor coordination are such that the brake is dropping just when
motor rotation stops.
4. Check that the brake pick delay allows the motor to build sufficient flux to prevent roll
back when the car is starting.
