CHAPTER 1
Mounting and controller’s connections
During controller’s mounting is advised to follow this instructions correctly.
Point - 1
Before mounting in the main board (fig. 1) please cut off rectangle hole 175 x 140 mm.
This hole should be made carefully thus rubber sealing is adjoined to the from panel.
Eventually any irregularity created after incorrect cutting out please smooth them using small
metal file and protect it by anti-corrosion painting. If on the main panel is no place to mount
controller, it is possible to add it as separate device (fig. 2).
Figure 1. Controller mounting on the main board.

Figure 2. Mounted controller as separate device.
In case of controller mounting as a
separate device it is possible after its assembly to attached it to the machine’s frame
using 4 added screws for this purpose. In another case please made special fixing for
mounting the controller which can be used as a distance support as well (fig. 2, E element).
Electric montage
CAUTION !
During electrical assembly there is a possibility of a electric shock thus all actions
should be made while electric power is off. For this purpose please turn off machine’s
main electric switch!!!
All cable connections should be made using special wires with double insulation
oriented for use of the electric devices powered by 230V alternating current. Cables
should be rounded with diameter suitable into holes in the controller back casing
accordingly. Tips of the cables should be cleaned and special quill should be used or
tips should be covered by thin tin layer. Please follow this instructions very carefully
especially electric connections should be made according to provided instructions. It is
required for correct and failure-free controller operating.
Machine where the controller is mounted should be equipped in well working head saw
ending switchers and contactors of the up and down feeding should be protected to be
on at the same time !!!

Power transformer TSS-8/24 assembly
In power cubicle added power transformer
TSS-8/24 needs to be mounted. Mounting is designed for well known and used holding bus
TSS-35. Please place the transformer as far as possible from other electrical elements ( e.g.
frequency changer, contactors, other transformers). It is important because of the
electromagnetic interference which may disturbing controller’s electronics. Please connect to
the connections marked as PRI power supply of 230V. For power supply please choose this
phase of electric supply of the machine which is not connected to the any inductions coils,
contactors or inverters. 230V supply cables should be placed as far as it is possible form other
cables in the power cubicle. To the transformer’s clips marked as SEC 24V please connect
wires which feed electronic plate of the controller. Analogically please place this wires as far
as it is possible from other power cables, especially from 230V which powered the
transformer. Length of the cables (24V) should be chosen accordingly to the place where the
controller is mounted.
Point – 3 Choke CPZ mounting
Anti-disturbance choke CPZ (WX1P 224M 440V)
added in the controller kit is designed to
protect from any other electromagnetic disturbance made by other electrical devices mounted
on the frame machine saw. Its correct mounting is decisive for correct controller operating.
Those CPZ outputs should connected in parallel to the contactors’ coil. CPZ should be
connected with contactor’s coil of the down feeding, up feeding and barker contactor
separately (if the sawing frame machine is equipped with barker).

Point -4
Rotating encoder mounting
Added rotating encoder is designed to convert rotation of the head saw feeding screw for
electrical impulses. Number of the impulses depends on screw pitch and this relation
describes table 1. In most of the frame sawing machines this screw has got free tip where the
encoder can be installed. Please make a concentric hole in the screw and mount encoder’s
clutch. Please make sure that this hole is concentric otherwise it can cause swinging and
eventually incorrect encoder working and its damage. Please make hole around 15 mm and
create thread M8. Next mount encoder using fixing band (fig.4). The band should be attached
to the special fixing which because of the variety of the frame sawing machines should be
created individually. Example of the encoder mounting is shown at the photo 4a below.

parameters.
Cable connection of the encoder should be routed as far as it is possible from other electrical
cables. Using special clip bands lead it to the place where the controller is mounted.

Point – 5
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.

Point 6
Installation of the up and down electronic feed limit switches.
Head movement limit switches are required for the correct operation of the adjuster. The set
includes 2 pcs of electronic magnetic limit switches type TS18-05P-2 Highly.
These are typical contactless sensors that respond to the approach of a metal element marking
the maximum movement of the machine head. These sensors should be mounted into pre-
made holes, using mounting nuts supplied with the sensor. The function of metal elements
activating the limit switch can be provided by angles attached to the moving part of the head
passing the face of the sensor at a distance of 2–4 mm. When routing the cable from the limit
switches, make sure that they are as far away as possible from other cables and power
devices.
Remember that there is a specific time interval between the moment the limit switch is
activated until the head stops, depending on the mechanical inertia of the machine. During
that time, the head passes a certain distance, therefore it is not possible to mount the sensor in
such a way that the activating metal element interferes with the location of the sensor (Figure
6). It is also necessary to provide for the possibility of changing (adjusting) the mounting
place of the metal element activating the limit switch so as to adjust the switch-off point of the
drive during the start-up of the adjuster.
Instead of electronic limit switches, you can also use good quality mechanical limit switches
with NC terminals, connecting them to the adjuster as shown in Figure 8.

Figure 6
Electrical connections of external components to the adjuster.
Before connecting the wires, it is absolutely necessary to turn off the power supply of the
converter and the ISP-12F adjuster!
Connection of control inputs of the frequency converter
For connection, use an 8-core screened control cable with a cross-section adapted to the
connection terminals.
The isolated ends of the individual conductors should be tightened in collets appropriate for
the given cross section; the use of collets improves electrical contact and prevents breaks in
connections. The screen (braid) of the cable should be connected to the connection only from
the side of the frequency converter!
Connection of cables from the adjuster to the converter should be made according to the
following description:
