CABLE INSTALLATION
Cable is factory installed and sealed. Consult factory for changes.
SPRING TENSION ADJUSTMENT
WARNING:
Do not allow cable to retract without restraining the retraction speed. Walk the cable back to the reel during
the spring tension adjusting process. Always maintain two full cable wraps on drum at maximum cable extension, size
cable accordingly.
1.
The EXPCRL reels come with pre-tension from the factory. Some adjustments may be required to meet
specific application requirements.
2.
To assure that the cable will retract properly and operate under the correct tension for intended
application; the reel should be tested. Securely mount reel before testing with cable installed on drum and end
of spool cable not connected, proceed with the next steps.
3.
Pull the cable out to the intended travel distance and allow it to rewind. This procedure should
be repeated five (5) to ten (10) times in order to set the spring. Walk the cable back to the reel during the
spring tension adjusting process.
Rotate Spool while holding Cable to Test the Spring Tension
4.
With all the cable wound on the reel, grasp the end of the cable and
rotate the drum and cable together in the direction of pay out in
order to pre-tension the spring. The number of pre- tension turns is
determined by cable size and footage. Usually, four to sixteen turns
is sufficient, but additional turns may be used if testing indicates that
the cable will not fully retract as desired with just four turns.
Adding Spring Tension
5.
Feed the end of the cable through the cable guide and pull the cable
out the required length.
6.
Repeat steps 3 to 5, if necessary, to add tension. To decrease
tension, rotate drum and cable counter-clockwise.
POWER CONNECTIONS
1.
Provide power source with over-current protection to prevent overheating of the reel and cable.
2.
Reels are supplied with cord to ballast box. Those cords are the same cable as is supplied on the spool.
They are factory sealed with explosion proof potting compound and supplied with a watertight strain relief. If
a conduit connection is required, the strain relief must be removed and conduit connections made.
OPERATION
1.
Do not exceed the voltage or amperage for the cable. Overheating, fire, damage to equipment or personal
injury could result.
2.
Do not allow cable to retract without restraining the retraction speed.
3.
Operate the reel within the cable size and length and spring tensioning limits for which it was intended.
4.
Keep two wraps of cable on the reel at maximum extension to avoid excessive tension on the cable and to
prevent pullout of cable from entrance watertight.
