head does not need to be mounted on bus. After the procedure is complete, the head
should be mounted as explained next.
In general, the head can be installed vertically or horizontally. The Measuring Head is
provided with feet for mounting to the floor or platform. The Measuring Head is also
equipped with holes in the corners that can be used for lifting to aid in installation. After the
head is installed in place, these holes can be used to install anti-tipping struts for head
stabilization. However, the corner holes should never be used to hang the head for
permanent installation without support for the bottom half. If the head is to be mounted
horizontally, then a platform must be used to ensure even weight distribution of the head.
There are two connector fittings on the Measuring Head (one on each half). These fittings
are not to be used for lifting. Proper lifting is accomplished by using eyebolts in the holes
provided in the corners. Choker slings may be used around the head as long as strong
lateral pressure on the edge of the window insulation is avoided.
CAUTION:
The part-line
insulation pieces (located on the mating surfaces of the head) are brittle and can be easily
damaged if one is not careful during installation.
Mounting the head:
1. Make absolutely certain that the serial numbers of both halves of the head match,
otherwise you may cause misalignment and unit failure.
2. Check the mating faces of the Measuring Head. Remove any dirt particles from the
head part-line insulation and multi-conductor connector.
3. Mount the Bottom half of the head on the floor or platform and secure it in place
temporarily. An arrow indicates the direction that conventional bus current must flow
through the aperture (+ to -).
4. Place the upper half of the Measuring Head over the bus. Make sure that the halves
go together squarely and evenly without forcing, twisting, or cocking. If for some
reason the head halves do not press tightly together, do not try to force the heads
closer together as it might lead to damage. Check and remove any obstacles that may
be preventing the head from assembling properly before proceeding. Also, if installing
multiple units make sure that the serial numbers match between the top and bottom
halves.
5. Connect the head halves using the provided M8 bolts. Tighten the bolts until snug - do
not over tighten. Maximum torque allowed is 135 in.lbs. (15 Nm). Since the bolts are
stainless steel, the bolts should be lubricated before installation to prevent them from
sticking or seizing. Molybdenum disulfide grease (“MolyLub”), or a dry (“MolyCote”)
type lubricant is recommended.
6. After final positioning of the head (see “Magnetic Centering” later in this section),
secure the mounting feet permanently to the floor or platform.
NOTE
When installing the Measuring Head, protect the window insulation from impact, and
do not let the weight of the Measuring Head rest upon the window insulation as it can
be easily damaged. Also, the interconnecting cable is of top quality, but it is not
armored - protect it from abrasion and sharp edges.
