Example of installation-mounting the magnetic switch on the
magnetic roller display
The magnetic switch is attached to the magnetic roller
display (4) of the UTN..EX indicator (6) by means of
tenon blocks. (Fig. 1)
1. Loosen the fastening bolts (1) on the magnetic
switch with an SW 3 hexagon socket wrench by
about 1 revolution.
2. Insert the tenon block(s) (2) into the guide groove
(3) on the magnetic roller display (4) from above or
below. (Please observe the position of the cable
threading or plug as per the Fig.)
3. Push the magnetic switch to the level of the desired
switching point and fasten it down there by
tightening the bolts (switching point is marked).
Important!
The magnetic switch MA is designed for installation on
the right-hand side of the magnetic roller display (4).
The switching function is reversed by mounting it on the
left side. The switch must then be mounted the other
way around (with the type plate upside down).
Example of installation MNAV
(mounting of magnetic switch on a
retainer rod)
This magnetic switch is attached to a retainer rod
that is mounted separately.
1. Remove the retainer rod (1) from the UTN...EX
rack by loosening the fastening bolts (2) and
removing the brackets (3).
2. Push the magnetic switch (4) onto the retainer
rod (1).
3. Then reattach the retainer rod (1) to the bypass
tube (5) using brackets (3) and fastening bolts.
4. Slide the magnetic switch to the level of the
desired switching point and fasten it down by
tightening the bolts (switching point is marked).
Important!
Please make sure the cable gland is positioned to point downwards during the installation
procedure. The magnetic switch casing must be touching the chamber to ensure a safe and
reliable switching function.
