Motor Auto Rewind Speed
The rewind speed needed depends upon the speed at which the crawler is
reversing, the size of the crawler wheels, the amount of cable on the drum and
the conditions in which the crawler is being used.
When the motor is rewinding, you should adjust the rewind speed so that there is
only a small amount of slack in the cable between the drum and the crawler, such
that:
• You ensure the motor is winding up enough cable onto the drum so that the
crawler does not run over the cable.
• You ensure the motor is not producing so much rewind speed that the drum is
dragging the crawler.
You may need to adjust the rewind speed a few times during the rewind of a long
length of cable.
With usage, you will gain some experience of the ideal settings for the rewind
speed.
When ACR operates in the modes which allow automatic payout (Assist Pay-out
Assist Fully) the payout speed can be limited. Payout speed limit can be used to:
• Prevent cable loops forming when cable is pulled manually and suddenly stopped.
• Deploy borehole camera.
• Doesn’t need adjusting for normal crawler operations. This setting can be
changed from the CCU cable menu by pressing up/down keyboard keys.
