OPERATION
RATCHET
When specified, reels are equipped with a ratchet lock. Tension of the
motor spring holds reel against ratchet. A sharp tug on cable releases
ratchet permitting reel to retract cable. Each ratchet dog is supplied
with counter-weight fastened by single screw. Ratchet position and the use
of the counter-weight depend upon the installed position of the reel. Here
are requirements for ratchet usage:
•
Wall mounting: Reel must be mounted with the ratchet side of the frame
down with counter-weight attached.
•
Base down mounting: Use the ratchet counter-weight.
•
Base up mounting: Remove the counter-weight.
SPRING TENSION
Reels are not pretensioned. To prepare reel for use, you must apply pretensioning turns to spool
assembly before connecting free end of working cable. The number of required setup turns can vary
considerably depending on application and on desired cable tension force. Set spring tension by turning
fully wrapped reel through a specific number of turns. See following guidelines on setup turns.
SET-UP TURNS
CAUTION:
Failure to test for adequate spring revolutions can cause spring damage. Hazards or
unsafe practices MAY result in
minor
personal injury or product or property damage.
Spring driven cable reels must always have setup turns applied before installing the cable free end.
A minimum of 2 set up turns are to be applied per spring in the reel.
See chart on next page for
minimum setup turn recommendation for your cable reel.
Example:
1475-16-320 cable reel requires 10 minimum setup turns
