Linear magnetic encoder mounting
(version for chain sawing frame machines)
In case of saw head fed with chain the linear magnetic encoder MSK-3200 needs to be used.
It works together with magnetic tape MB-3200.
The magnetic tape contains two parts which contains with self-adhesive layer. First,
thicker part please place on the smooth and flatten surface (please clean the surface carefully
before sticking the tape using acetone or spirit). During sticking please get unstuck only small
part of the tape on the tip and stick it to the surface. Next get unstuck rest of the tape slowly
sticking it to the surface simultaneously. During sticking please use rubber roll to create
bigger adhesive pressure. Please stick the tape very careful and try to not create any air
bulging and notice to stick it straight. Next please stick the second part of the magnetic tape –
steel protection strip using the same proceeding as above. Both tapes should be stuck in one
line laying on each other creating two layers. Sensor MSK-3200 should be mounted on not
moveable part of the machine (according to the controller) to not create any cable movements
which can cause its damage. In case of mounting sensor on moveable part please protect cable
from its non-controlled damage leading it in a special portable buses. Sensor should be
mounted with two screws in a way that the magnetic tape should be in a 1 to 1,5 mm distance
and in parallel with it. Please notice during leading the cable to place it as far as it is possible
from other cables. Please do not place any sources of the magnetic field next to the magnetic
tape during, before and after mounting. It may cause it serious damage and incorrect working
of the controller. Please clean the surface of the tape from time to time with sift brush.
Please do not hit senor or the tape. The sensor should be mounted in that way thus text
SCALE SLIDE is faced on the magnetic tape side. The sensor and the tape should be mounted
in a such way that during feeding sensor “is above” the tape in all range. Please notice the
stability of the tape and the sensor during normal operating.
