POWER SUPPLY AND
ELECTRICAL CONNECTIONS
The hoist should be connected to a branch circuit which
complies with the requirements of the National Electrical
Code and applicable local codes.
It is recommended, especially for a single phase hoist with a
(1) horsepower motor (.75 Kilowatts), that a line of adequate
capacity be run directly from the power supply to the hoist to
prevent problems with low voltage and circuit overloads.
For grounding of the hoist, the power cord includes a grounding
conductor (green yellow, G-Y). 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 hoist identification plate is:
THREE PHASE HOIST
Unless ordered on a special basis, all single speed/dual volt-
age (230/460-3-60, 220/380-3-50 and 220/415-3-50) hoists
are factory arranged to operate on 460-3-60 (or 380-3-50 or
415-3-50). However, a voltage change board is provided to
easily and quickly change from 460 to 230 (or 380 to 220 or
415 to 220) volt operation. The voltage change board shown
in Figure 12 is located in the hoist as shown in Figure 13.
Voltage change board is located under back frame cover
(1) for Models B, C & F and under motor housing cover (2)
for Models J, L, LL, R and RR.
The voltage change board is color coded to indicate high and
low volt connections. Connecting the 9 and 12 pin plugs into
the “Red” voltage change board receptacles will connect the
hoist for high voltage (380-3-50, 415-3-50 or 460-3-60). To
change the hoist voltage to low voltage (208-3-60, 220-3-50
or 230-3-60) simply remove the 9 and 12 pin plugs from the
“Red” recepticles and insert same into the “White” receptacles
located on the voltage change board.
Be sure to make a notation of the new hoist voltage on the
tag attached to the power cord.
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 prior to each usage.
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 opposite to that indicated by the control station.
Therefore, proceed as follows:
1. Make temporary connections at the power supply.
2. Operate
ជ
(UP) control momentarily. If hook raises,
connections are correct and can be made permanent.
3. If hook lowers, it is necessary to change direction by
inter-changing the Grey lead and the Black lead of hoist
power supply. Under no circustances should the internal
wiring of the control device or hoist be changed to
reverse hook direction. The wiring is inspected and
tested before leaving the factory.
Do not force the Lodestar Load-limiter to compensate for
improperly adjusted limit switches or reverse voltage phasing.
