8. Engage the second side plate (item 6) ensuring that roll pins
(item 8) engage into one of the bores in the round nuts
(item 5). To achieve this, it may be necessary to rotate the round
nuts slightly.
9. Tighten the hex. nuts (item 2) on the second side plate.
Tighten locknuts (item 9) finger tight and then, a further 1/4 to
1/2 turn.
Attention:
The locknuts must always be fitted.
10.By traversing the trolley, check the following:
• A clearance of 2mm is maintained on each side between
the trolley wheel flanges and the beam outer edge.
• The suspension traverse is centred below the beam.
• All 4 locknuts (item 9) are fitted.
11.Model CPV/F-VTG only:
To fit the hand chain, position the slot on the outer edge of
the hand chain wheel below the chain guide. Place any one link
of the endless hand chain vertically into the slot and turn
the hand chain wheel until the link has passed the chain
guides on both sides. Please note that geared trolleys are
moved by operating the hand chain.
Attention:
Do not twist the hand chain when fitting.
Shortening or extending the hand chain.
(Model CPV/F with hand chain drive only)
The length of the hand chain should be adjusted so that the
distance to the floor is 500 - 1000mm.
1. Identify the split link in the hand chain and open by bending
to the side. This allows the adjacent link to be removed.
2. Shorten or extend the hand chain as required.
Note:
The number of removed or added chain links must
always be even.
3. Close the open connecting link by bending back to the centre.
4.4 ELECTRICAL CONNECTION
Attention!
Work at electrical installations may be carried out only by
qualified electrical engineers. The local regulations have
to be strictly observed, e.g. EN 60204-32 / VDE 0113.
Preparation
•
Before beginning work on electrical components, the mains
current switch must be switched OFF and secured against
unintentionally being switch back on.
• Before connecting the chain hoist, ensure that the electrical
data on the nameplate match the local specifications.
• The mains supply cable must be an insulated cable with 4
flexible leads. The ground (earth) lead must be longer than
the live leads. For wire cross-section and fusing of the
various models, see tables on page 7. Cable ends have to
be provided with end sleeves.
• The length of the pendant control cable is determined by
working conditions. Attach the tension relief wire so that the
pendant control cable hangs free of the load.
• Wiring and terminal connecting diagrams are included with
the hoist and shown on the inside of the control cover.
Mains supply connection
1. The mains supply cable must be connected to the electric
chain hoist before it is connected to the mains supply.
2. On chain hoists with an electric trolley (CPV/F-VTE), the three
phases of the mains supply are to be connected to the terminal
strip within the control box on the trolley. The ground/earth wire
is then to be connected to a special protective terminal inside
the control box of the hoist.
3. On chain hoists without electric trolley, the mains supply
cable is connected to the terminals marked (L1), (L2) and (L3)
on the contactor marked (K0) which is subsequently mounted
onto the circuit board, located behind the housing cover
(Fig. 1). You must ensure that the ground/earth cable is secured
to the circuit board frame using the screw and serrated washer
supplied.
4. After removing the terminal box cover, connect the wiring as
shown on the wiring diagram attached.
5. After replacing the terminal box cover, connect the other end
of the supply cable to the disengaged mains switch and power
supply system respectively.
6. Check the motor’s direction of rotation.
The wiring diagram included has been drawn for a normal,
clockwise rotating installation. Should the user’s mains supply
not fulfil these requirements, e.g. the hoist lowers when lift is
selected (or visa versa), switch the unit OFF immediately and
exchange two of the three phase connections in the terminal
box.
Under no circumstances may the wiring in the pendant
control be changed to compensate incorrect phase
connections.
