Checking For Twists In Load Chain; Checking For Adequate Voltage At Hoist; Limit Switches - CM LODESTAR 635 Serie Manuel D'entretien, D'opération Et De Pièces

NOTE: Before connecting the hoist to the power supply, check
that the power to be used agrees with the position of voltage
change plug on the voltage change board.
The nominal hoist voltage rating corresponding to the voltage range
given on the hoist identification plate is:
Single Speed Units
Range Nominal Volts
110-120 115
208-240 230
440-480 460
THREE PHASE HOIST
Unless ordered on a special basis, all single speed dual voltage
(230/460-3-60, 220/230-3-50 and 220/415-3-50) hoists are factory
set to operate on 460-3-60 (380-3-50 or 415-3- 50). However, a
voltage conversion board is provided to easily and quickly change
from 460 to 230 (or 380 to 220 or 415 to 220) volt operation. The
voltage conversion board shown in Figure 12 is located in the hoist
as shown in Figure 13.
Figure 13. Location of Components
Voltage conversion board is located under frame cover (1) for
Models A thru H and under motor housing cover (2) for Models
J thru RRT.
Limit switches and electric brake are located under frame cover
(1) for all hoists.
PROPER PHASING
Since the motor in a three phase hoist can rotate in either direction,
depending on the manner in which it is connected to the power
supply, the direction of hook movement must be checked during the
original installation and each time hoist is moved to a new location.
Note: Serious damage can result if the hook is run to the upper
or lower limit of travel with the hook operating in a direction
Two Speed Units
opposite to that indicated by the control station.
Range Nominal Volts
Therefore, proceed as follows:
208-230 230
440-460 460
Also, do not force the Lodestar Protector to compensate for
improperly adjusted limit switches or reverse voltage phasing.
CHECKING FOR TWIST IN LOAD CHAIN
MODELS E, H, E-2,H-2, R, RR, R-2 AND RR-2
The best way to check for this condition is to run the lower hook,
without a load, up to within 24 inches (609 mm) of hoist. If the dead
end of the chain has been properly installed, a twist can occur only
if the lower hook block has been capsized between the strands of
chain. Reverse capsize to remove twist.
MODELS RT, RT-2, RRT AND RRT-2
On these models, the load chain is dead ended on top of the lower
hook block. If the chain has been properly installed, the only way
a twist can occur is if the lower hook block has been capsized
between the strands of chain. If this has occurred, two strands of
chain will be wrapped around each other and to remove this, reverse
the capsize.

CHECKING FOR ADEQUATE VOLTAGE AT HOIST

The hoist must be supplied with adequate electrical power in order
to operate properly. For proper operation, the voltage, (measured
at the end of the standard 15 foot (4.6 m) power cord with the hoist
operating in the , up direction with full load) must be as indicated in
the table below.
11
(ENGLISH)
1. 1. Make temporary connections at the power supply.
2. Operate (UP) control in control station momentarily. If hook
raises, connections are correct and can be made permanent.
3. If hook lowers, it is necessary to change direction by
interchanging the Red lead and the Black lead of hoist power
cord at power supply. Under no circumstances should the
internal wiring of control station or hoist be changed to reverse
hook direction. The wiring is inspected and tested before
leaving the factory.
Allowing the hook block to run into the bottom of the hoist when
raising a load or allowing the chain to become taut between the
loose end screw and the frame when lowering a load may break
the chain and allow the load to drop.
TO AVOID INJURY:
Do not allow the hook block to contact the bottom of the hoist or
the loose end chain to become taut.
