3.0 SYSTEM OPERATION
3.1 Determine wireline size to be used – .092" to 3/16”
Since the wireline wraps around the depth wheel, the circumference of the
depth wheel will change with a change in wire size. The wheel size needs
to be corrected for wireline size in order to accurately measure depth.
These corrections are automatically made in the BenchMark hoistman's
panel by selecting the proper cable size using the menu. If a different panel
is used, the wheel size will need to be set at this time.
3.2 Install wire in measuring head using the following procedure:
(refer to figure on following page).
1. Run the wireline from the drum, through the drum side spooling
rollers, onto the left side (facing the drum) of the depth wheel.
2. Pull the wireline across the depth wheel, under the spooling roller
plate around the tension wheel.
3. Make sure the guide rollers are loose so the wireline can be installed
on the tension wheel.
4. Pull the wireline from the bottom of the tension wheel around the
bottom of depth wheel, under the spring mounted tension roller
(mounted on the rear of the depth wheel), around the top of the
depth wheel (right side), and through the rig side spooling rollers.
5. To open the spring mounted pressure roller, press on the back near
the spring or insert a hex wrench into the pressure roller bolt and pull
back.
6. After the wireline is installed, tighten the guide rollers. They should
be barely touching the wireline in the tension wheel. If they are
pressed too tightly against the wireline, the tension measurement will
be affected.
