2 Precautions and restrictions on use

2.1 Restrictions on use

This equipment is designed for dry running.

Any oily material alters performance.

2.2 Precautions and safety measures

During the maintenance period make sure that the

moving parts of the machine are stationary and

that there is no risk of start-up.

Exceeding the maximum rotation speed

stated in the catalogue invalidates the

warranty.

Any modification made to the unit without

any express approval of a Warner Electric
representative will invalidate the guarantee and

This equipment is designed for a maximum

ambi ent temperature of 40°C (155°C casing

release Warner Electric from any liability regarding

conformity.

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.

3.3 Installation 3.3.1SFM (VAR00 and VAR01)

Inductor (104) should be fixed to the frame of the

machine, centred by the collar (see figure 1) or

directly centred on a bearing forming a support

(see figure 2). In this case, a circlip fitted in the

groove provided for the purpose holds it central to

the bearing.

In the case of collar centring, we specify an H9

tolerance.

Airgap

Adjusting spacer

Fig. 2

On VAR01 the armature is mounted on a hub

(332), sup plied reamed to tolerance H7 and
splined to tolerance P9.

The assembled hub / armature assembly

should be secured centrally so as to respecter

the nominal airgap.

It is essential when assembling to respect the

nominal airgap (see chapter 1) and dimension

M (See table 1).

The setover between the housing and shaft should

not exceed 0.05 mm.

On VAR00, the armature (331) is fixed by means

of CHC “profile head” screws (DIN 7984) locked
by means of a LOCTITE 270 type thermoplastic
liquid.

Airgap

Adjusting
spacer

Fig. 1

In the case where two co-axial shafts are fitted,

the recommended setover is 0.05 mm maximum.

The angular misalignment should not be greater

than 0,1 mm over a length of 100 mm.

When assembling or dismantling the moving

armature, never hit or pull it, this action could

generate permanent distortion of the

membrane-spring and malfunction.

3.3.2 SFM (VAR10 and VAR11)

The inductor (109) is stopped from rotating by

means of a stop foot. This should be fitted so
as to get a minimum play of 0,25 mm between
the sides of the notch to avoid any strain on the

inductor and internal bearing.

In case of vibrations, it is strongly recommended

to insert a damping elastic slot between the
anti-rotation device and the anti-rotation slot
and to fix the coil’s cable the nearest of it to

avoid whipping.

On VAR10, the armature is fixed (331) by means

of CHC “profile head” screws (DIN 7984) locked
by means of a LOCTITE 270 type thermoplastic
liquid.

4 Electrical connection

SFM and PBM equipment should be supplied

with Direct Current and has factory fitted wires
of length 400 mm. Polarity has no effect on
operation.

4.1 Important recommendations

Ensure that the nominal supply voltage is

complied with (a lower voltage causes a reduction
in the starting distance and transmissible torque).

The connecting wires should be of sufficient

diameter to prevent power loss between source

and the equipment to be supplied.

4.2 Power supply

For the control of these clutches and brakes we

advise the use of Warner Electric CBC 140-4,

CBC 140-6, CBC 400, CBC 450, CBC 500, CBC
550, and CBC 700 supply units.

Warner Electric supply units provide protection

for the coils and circuits. In the case where a
brake or clutch is used without our supply units,
with switch on the DC circuit, it is essential
to protect the coil against power spikes by a

varistor fitted in parallel.
