5. Troubleshooting

When the brake does not perform as intended, check followings.

Brake is slipping.

Is the friction plate soiled with oil?

Is temperature of the brake too high? (over 100 °C)

Is excessive load applied to the machine?

Sluggish operation of the brake

Is sufficient voltage being supplied?

Is the friction plate worn out ? (too much gap)

Is brake temperature too high? (over 100 °C)

The brake does not operate entirely.

Breakage of coil and/or lead wire

Electrical circuit failure

Too much gap of the friction plate because of wear?

Is sufficient voltage being supplied?
