2 Precautions and restrictions on use

Symbol designating
an action that might
damage the brake

2.1 Restrictions on use

This equipment is designed for dry running.
Any oily material alters performance.

Exceeding the maximum rotation speeds
stated in the catalogue invalidates the warranty.

The equipment can be fitted either horizontally
or vertically.

This equipment is designed for an ambient
tem perature of 40°C maximum (155°C
insulation class).

Symbol designating an
action that might be
dan gerous to human safety

2.2 Precautions and safety measures

During maintenance, ensure that the

mechanism to be braked by the equipment is at
rest and that there is no risk of accidental start­up. All intervention have to be made by qualified
personnel, owning this manual

Any modification made to the brake without

the express authorization of a representative of
Warner Electric, in the same way than any use
out of the contrac tual specifications accepted by
“Warner Electric”, will result in the warranty being
invalidated and Warner Electric will no longer be
liable in any way with regard to conformity.

3 Installation

3.1 Transport / storage

These units are delivered in packaging that

guarantees a 6 months storage period whether
transported by land, by air, or by sea to any
destination excepting tropical countries.

3.2 Handling

Avoid any impacts on the equipment so as not

to alter their performance.

Never carry the equipment by the electrical

supply cable.

3.2 Installing

NB : ERD Size 005 to 035 brakes are supplied

in kit form. The pre-assembled inductor is
supplied with airgap adjusted, see chapter 7
(appendix).

Customer shall maintain:

1. Squareness of flange mounting face
with shaft within 0,15 mm T.I.R. measured at
mounting shaft.

2. Concentricity of flange mounting with
mounting shaft within 0,15 mm T.I.R.

3. The mounting surface should be made of
steel or cast iron, square to the shaft with a
surface finish of 5 to 8 µm or a fine turned finish

over the contact area

If a friction flange (340) or (341) is supplied, fix it

first.

Switch the equipment on and confirm that the

friction disc rotates freely.

Cycle the brake a number of times and re-check

the value of the airgap. If the airgap is incorrect,
refer to chapter 4 (maintenance).

4 Maintenance

4.1 Adjusting the airgap

To reset the airgap (figure 1), undo the adjustment

bolts and adjust to obtain the necessary gap
size, (see table 1). Measure the airgap at several
points. Cycle the brake a num ber of times then
re-check.

4.2 Maintenance

Wear in the friction material causes an increase

in the air gap. Before reaching the maximum
airgap, see table 1, it is necessary adjust it, see
Fig. 1.

4.3 Spare parts

After several adjustments, variable according

to size and use, it is necessary to replace the
friction disc, see Fig. 2 and table 2.

Put the key into the shaft then slide the hub

(515) onto the shaft and secure it axially by
suitable means.

To replace the friction disc (312) or (315), undo the

fixing bolts (913) or (914) then take off the pre-
assembled induc tor (108) and then the friction
disc. Put the new friction disc into position then

Slide the friction disc (312) or (315) onto the

hub.

If a hand release kit is supplied, it is advisable to

refit the pre-assembled inductor and re adjust the
airgap, see paragraph 4.1.

E

mount it onto the pre-assembled inductor before
the inductor is fitted, see chapter 6.

Fit the pre-assembled inductor (108), remove

the transport shims (551) and fix using the fixing
bolts (913) or (914). Noting carefully the tightening
torque, see table 1.

Secure the bolts using a LOCTITE 270 type

thermoplas tic liquid. If a dust cover (555) is
supplied, carefully slide it onto the equipment
before fitting.
