brake coil is energized) to the values as indicated in the table below.

I.e., due to the natural wear of the lining, the size of the air gap gradually increases without affecting the performance of the brake until it reaches the maximum adjustment value shown on table below. The friction lining is dimensioned such that the brake can be readjusted at least five times.

Rapid braking

In this case a contact is used to interrupt the direct current electromagnet coil. The contact must be a N.O. auxiliarycontact of the motor contactor.

Peculiarities

Connections 3 and 4 to auxliary contact of the relay or electronics relays of current RSR10 / RSR50 to the exactly adjust of the time of actuation of the brake through by a separation on the side of the current - CC.

To readjust the air gap (S_l0) to the initial value, proceed as follows:

• Remove the fan cowl.

• Measure the air gap in three places, near the adjustment screws, using a set of feeler gauges.

• If the width of the gap is equal to or greater than the maximum indicated (S_l0 max), fit the gap until the initial value (S_l0).

• Loosen the fixing bolts and the adjustment screws.

• Adjust the air gap to the initial value indicated in table above by equal lyadjusting the three adjustment screws. The value of the air gap must be uniform at the three measured points, and be such that the feeler gauge corresponding to the gap (S_l0).

• Adjust the screws until the ends touch the motor endshield. Do not adjust any further.

• Tghten the fixng bolts.

• Re-check the air gap to ensure the measurements are as per the value S_l0 above.

• Replace the fan cowl.

Life of the Brake Lining:

The necessary friction work depends on a number of factors, namely the inertia to be braked, the braking speed, the operatingfrequencyand thus the temperature at the friction faces. Therefore, no general statement can be made about the friction work available until adjustment, which is valid for all operating conditions.

Note: Wthout the relay of the current and without mechanic auxliary contact must be connected a bridge of wire on fittings 3 and 4.

Brake Maintenance

Because of the simple construction WEG brake motors require very little maintenance - basically only a periodical adjustment of the air gap.

Air Gap of the Brake:

WEG brake motors are supplied with an initial factory set air gap (a gap between the armature and frame when the
