(6) Wrap thick tape around the cable portion which contacts with the oblon hole in the
drum cover, and fix with the saddle.
If the cable cannot be secured by the saddle, make the cable diameter bi er by wrappin
thick tape around the cable (See fi ure 15).
(7) Connect each core to the brush.
When each line core connect to solderless terminal, make thicker and connect it.
See fi ure 16. If it's not thick enou h, the line core come out from terminal.

■ Fixed side cable (See fi ure 13 (pa e 11))
(1) Remove the connector nut on the spindle side.
Attache the connector nut, washer and sleeve to the cable.
(2) Peel 100 mm of jacket from the cable, and pass the cable throu h the spindle.
(3) Connect each cable core to the terminal plate.
NOTE: Check the conduction of each cable core to ensure there are no wirin errors.
(4) Ti hten the connector nut to secure the cable.
This is important to prevent rain penetration into the slip rin assembly.
NOTE: If the cable cannot be secured by ti htenin the connector nut, make the cable
diameter bi er by wrappin thick tape around the cable, then secure with the
connector nut (See fi ure 14).

6 Spring tension adjustment
6-1. Relationship between windin torque and drum turns
Fi ure 17
"Number of initial sprin turns" means the number of sprin turns which provides the
initial tension required for windin the cable onto the drum.
"Number of spare sprin turns" means the number of remainin sprin turns when the
cable is fully paid out.
A shorta e of spare sprin turns shortens the sprin life and causes sprin breaka e.
6-2. Standard value of initial sprin turns and calculation for upper limit of
initial sprin turns
(1) Check the total number of sprin turns usin table 1(pa e 6).
(2) Rotate the drum by hand until the cable of the windin len th is fully retracted, checkin
the number of drum turns.
(3) Check the standard value of initial sprin turns and the number of spare sprin turns
usin table 2.

Example) Model CRL-2A205W, for the case of 20 drum turns
Accordin to table 1, total number of sprin turns = 39.
Accordin to table 2, standard value of initial sprin turns = 2 - 6,
Number of spare sprin turns = 3 or more.
Upper limit of initial sprin turns = 39 - (20 + 3) = 16.
Then the allowable number of initial sprin turns = 2 - 16.
6-3. Initial tension settin
・
・・
・Never let go of the drum during any work.
When released, the drum suddenly rotates, possibly ausing personal injury.
・
・・
・After setting the initial tension, wire onne tion requires more t
han 2 people to se ure the
drum and onne t the able.
(1) Before wire connection, wind the whole cable around the drum.
NOTE: Take care not to twist the cable durin windin .
(2) With the cable still wrapped around the drum, rotate the drum by hand in the payout
direction the same number of turns as the standard value of initial sprin turns.
This becomes "initial sprin turns".
(3) Without lettin the drum rotate, unwind the cable to the extension len th plus the
connection len th and connect the cable to the matin equipment.
Check there are no twists in the cable before connection.
(4) Pull out the cable to the windin len th, then let the cable wind around the drum.
Ensure the drum can recover the cable's full windin len th.
(5) If the drum stops durin recovery, the initial sprin tension is insufficient.
Disconnect the cable from the matin equipment and increase the number of initial
sprin turns in the same manner.
NOTE: Set the initial tension as small as possible and never exceed the upper limit of the
initial sprin turns.
Over-tensionin could cause a sprin breaka e.
7 Measures against uneven winding
"Uneven windin " means the cable is wound on mainly one side of the drum width.
The uneven windin will cause the cable to drop from the drum or recovery problems,
resultin in dama e to the cable.
7-1. Checks before adjustments
(1) Check the reel position is correct.
Refer to Chapter 4, Section 4-2. "Installation".
Adjust the X and Y axes of the reel.
(2) Check there are no twists in the windin side cable.
Disconnect the cable from the matin equipment and remove any twists.
※ If uneven windin still exists after the above checks, adjust accordin to the next section.

7-2. Adjustments
(1) Initial tension modification
Increase the number of initial sprin turns one by one without exceedin the upper limit.
If there is no improvement, set the initial tension back to the first value.
(2) X axis modification
Tilt the X axis at a small an le by insertin a spacer under the bracket.

(3) Y axis modification
Tilt the Y axis at a small an le after adjustin the X axis.

8. Safety instructions on use
・
・・
・Never approa h the moving parts during operation.
There is a danger of being aught up.
・
・・
・Turn off the power immediately in ase of any trouble to avoid the problem es alating.
・
・・
・Never use the reel when damaged or abnormal sound/vibration o urs.
・
・・
・Never alter the reel or its a essories.
・
・・
・Never let go of or unfasten the able from the fixed points when the able is pulled out.
The able will rewind suddenly, possibly ausing personal injury.
・
・・
・Use within the rated values of the operating voltage and urrent.
Refer to the name plate atta hed to the body.
・
・・
・Never pull out the able past the winding length.
Always leave 2 - 3 dead turns on the drum. (To the sign of red tape)
Put sign (red tape) on the 2 – 3 dead turns when installing or repla ing the able.
