10.Securely reposition the guide plate in the slot
11.Reconnect hoist to power supply and check the stopping
point of hook by first lowering the hook about 2 feet
(61 cm), then raise the hook by jogging cautiously until
the upper limit switch stops upward motion. The stopping
point of hook should be the desired upper position. If not,
repeat the above instructions.
12.Double check setting by lowering the hook about 2 feet
(61 cm) and then run the hook into the upper limit with
ជ
(UP) control held depressed.
13.Fine adjustment of the upper limit setting may be
obtained by inverting the stationary guide plate in Step
10. The offset on the plate gives adjustments equivalent
to1/2 notch, seeTable 6 for the “Hook Travel Per Notch of
Limit Switch Nut”. . When inverting the plate, it may be
necessary to use the notch adjacent to the one used in
the preliminary setting.
SETTING LOWER LIMIT SWITCH
After completing steps1 thru 4
5. Refer to Table 6 -The “B” dimensions given are the minimum
length of loose end chain left on the loose side of the lift
wheel when the hook is positioned at the lowest allowable
hook position.
CAUTION: THE “B” DIMENSIONS SHOWN IN TABLE 6
ARE THE MINIMUM ALLOWED FOR SAFE OPERATIONS
AND SHOULD NOT BE REDUCED.
6. Reconnect hoist to power supply.
7. Run hook to the desired lower position, cautiously operating
the hoist without a load.
8. Disconnect hoist from power supply.
9. Moving one travel nut toward the other increases hook
travel and away from the other decreases hook travel.
Now, turn the nut nearest the switch indicated as the
“LOWER LIMIT SWITCH” until it just breaks the limit
switch contacts, cautious not to allow the movement of
the other travel nut if previously set.
An audible click will be heard as the switch opens.
Continue to rotate the nut toward the switch an additional
one full tooth.
10.Securely reposition the guide plate in the slot.
11.Reconnect hoist to power supply and check the stopping
point of hook by first raising the hook about 2 feet (61cm )
then lower the hook by jogging cautiously until the lower
limit switch stops downward motion. The stopping point
of the hook should be the desired lower position, if not
repeat the above instructions.
12.Double check setting by raising the hook about 2 feet
(61 cm) and then run the hook into the lower limit with
ឆ
(DOWN) control held depressed.
13.Fine adjustment of the lower limit setting may be obtained
by inverting the stationary guide plate in Step 10. (Not
available with the rotatable guide plate). The offset on the
gives adjustments equivalent to 1/2 notch, see Table 6
for the “Hook Travel Per Notch of Limit Switch Nut”. When
inverting the plate, it may be necessary to use the notch
adjacent to the one used in the preliminary setting.
CONVERTING LIMIT SWITCH GUIDES
1. Disconnect the hoist from the power supply system.
2. Refer to the exploded views and remove the back frame cover
from the hoist.
3. Remove and discard the limit switch guide plate - retaining
the 2 screws.
4. Refer to Figure 18A and 19A and assemble the limit switch
guide plate to the limit switch bracket. Secure using the 2
screws.
