Magnetic Copying Accessories Set (MCAS)
2.2.2.1 Operating limitations
z
Only ferromagnetic materials (iron, steel, cast iron) can be investigated . For non-
ferromagnetic materials (aluminum) eddy-current scanner must be used (supplied
optionally) .
z
Thickness of investigated lacquer-and-paint coating shall not exceed 0,5 mm and
the thickness of investigated rust or scale layer shall not exceed 0,3 mm .
z
Investigated surface unevenness shall not exceed 0,5 mm at the basic width of 11 mm
when using a flat concentrator of the Combination Magnetic Scanner (CMS) .
z
Investigated surface unevenness shall not exceed 1 mm at the basic width of 20 mm
when using a rotary concentrator of the CMS .
z
Protect CMS from impacts and falls to avoid magnets failure and loss of magnetic
properties .
z
Damaged rubber protective sleeve gaskets should not be used during the operation of
CMS with rotary concentrator .
2.2.2
Do not use the magnetic tape shorter than 150 mm, otherwise in case of tape
jamming in the tape path there won’t be a possibility of manual tape removal and
this case may require the backup of the service engineer.
2.2.2.2 Preparation of the device for operation
z
Check availability and proper arrangement of the set components .
z
Check availability of reserve of the magnetic tape and ethyl alcohol .
z
Inspect the integrity and cleanliness of magnetic tapes surface . (See “The Order of
Refilling”) .
z
Visually control integrity of rubber protection sleeve gasket of the Combination Magnetic
Scanner with rotary concentrator . If necessary replace the worn out sleeve gasket with
a new one (see paragraph 4 .2) .
Magnetic tape (MT) and ethyl alcohol are consumable materials .
To fill up an operative stock of magnetic tape perform the following: take MT from Spare Parts
and Repair Kit (SPRK), cut it into necessary length strips and enclose them into the cartridge
for magnetic tapes storage (Figure 1, pos . 11) .
Cut metal MT with the cutter from SPRK in the following sequence:
z
set the cutter lever in the upper position (Figure 5, pos .1), letting the tape freely pass
through the slot as it is shown in Figure 5a;
z
push the magnetic tape strip (Figure 5, pos .3) out of the blade edges (Figure 5, pos . 2),
pressing the surface of the magnetic tape at the number area site (Figure 5, pos .6);
