AND

LOWER

LIMIT

SWITCHES

–

ROPE

GUIDED

Each

hoist

is

fitted

with

an

upper

and

lower

level

hoist

limit

switch.

The

limit

switches

are

activated

by

contact

with

the

travelling

rope

guide

retainer.

These

are

safety

switches

and

should

not

be

used

as

the

normal

method

for

stopping

the

hoist.

When

activated,

each

switch

will

only

allow

travel

in

the

opposite

direction.

Remove

the

hoist

cover

to

gain

access

to

the

limit

switches.

NOTE:

The

limit

spacer

tubes

are

designed

to

prevent

the

switches

from

being

placed

outside

the

normal

range

of

operation.

Do

not

remove

or

modify

these

tubes.

Incorrect

setting

of

the

limit

switches

may

cause

serious

accidents

and

damage

to

the

hoist

unit.

Setting

the

lower

limit



Release

the

grub

screws

that

secure

the

holding

arm

to

the

limit

bars

and

slide

the

switch

towards

the

end

of

the

hoist.



Lower

the

hook

to

the

desired

lowest

operating

position.

Do

not

let

the

hook

touch

the

floor

such

that

it

would

cause

the

ropes

to

go

slack.



NOTE:

The

clearance

between

the

rope

guide

and

the

rope

clamps

should

not

be

less

than

10mm

when

the

hook

is

at

its

lowest

position.



Slide

the

limit

switch

up

to

the

rope

guide

retainer

until

the

switch

is

activated.

Tighten

the

grub

screws

holding

the

arm

to

the

limit

bar.



Test

that

the

limit

operates

satisfactorily

firstly

at

slow

speed

and

then

at

fast

speed.

Re

‐

adjust

if

necessary.

When

the

adjustments

are

complete,

replace

the

hoist

cover.

to

the

correct

operating

position.

for

low

vary

with

is

set

higher

than

the

values
