3.3.3 Installing VAR05

•

After adjusting the driving key, mount the inductor

onto the shaft, then fit the adjusting spacer (526) and
the bearing assembly and finally lock the whole axially
on the shaft.

Sizes 3200 and 6400 : the coupling flange (528) is not
mounted in our workshops. After mounting the u to
thshaft, fit the flange with the screws provided to the
spe cified torque (see Table 2) and secure them with
Loctite 243 or equivalent.

NB.: VAR05 is delivered with a pre-adjusted airgap.
However check the value J between tooth heads after
mounting. (see Table 1).

•

Mount the coupling hub (507) onto the second

shaft and lock it axially

•

Put the spider (730) inside the coupling flange (528)

•

Assemble the driving part with the driven part and

insert the coupling hub with the spider (730)

While mounting the unit, it is essential that you
note value E (elastic coupling mounting),

see Table 1.

4 Maintenance

After continued operation it may become necessary to
change bearings. The inductor bearings are mounted
in a special way, and we recommend returning the unit
back to the factory for replacement.

Electrical connection

E320 units must be supplied with direct current (D.C)
and are equipped with a 500 mm length wire. Polarity
does not affect the functioning.

5.1

Important recommendations

All works on the electrical connections have to
be made with power off.

Ensure compliance with the nominal supply voltage
(inade quate supply causes a reduction in the starting
distance and transmissible torque).

The connecting wires should be of sufficient diameter
to prevent voltage drops between the source and
equipment supplied.

Tolerance in the supply voltage to the clutch terminals
+5% / -10% (NF C 79-300).

5.2

Supply

For controlling these clutches, we advise the use of
Warner Electric supply units

Sizes 20 to 3200:

CBC 400-24, CBC450-24
CBC 140-5

Sizes 6400 to 12800:

CBC 140-5

Warner Electric supply units provide protection for coils
and circuits. Where a clutch is used without our supply
units, with switching on the DC, it is essential for the
coil to be protected against surges by a varistor fitted
in parallel.
