Fitting
the
brake
seal
kit
(optional)
Pull
the
electrical
cable
through
the
rubber
sealing
ring.
Drop
the
outer
brake
seal
(8a)
over
the
hand
release
lever
and
push
the
sealing
ring
over
the
stator.
Press
the
lips
of
the
seal
into
the
grooves
into
the
stator
(1)
and
the
mounting
flange
(4)
(see
Figure
52).
Tap
the
stator
brake
seal
(8b)
into
the
hole
in
the

Brake
rectifier
The
ZX
series
hoist
uses
three
types
of
brake
rectifier.
These
vary
with
the
size
of
brake.
The
rectifier
type
is
marked
on
the
rectifier.

With
the
brake
connected
to
the
rectifier,
check
that
the
input
voltage
to
the
rectifier
is
correct
at
220V.
The
output,
measured
at
the
brake
coil
terminals,
should
be
approximately
198V
DC.
Testing

rectifier,
type

With
the
brake
connected
to
the
rectifier,
check
that
the
input
voltage
to
the
rectifier
is
correct
at
220V.
The
output,
measured
at
the
brake
coil
terminals,
should
be
198V
DC
for
1
second
and
then
reduce
to
and
hold
at
98V
DC
(note
these
values
are
approximate
only).
Use
an
analogue
meter
for
this
test
(a
digital
meter
is
not
suitable).
If
the
output
voltage
from
the
test
is
below
the
figures
provided,
the
rectifier
should
be
replaced.
