2 INSTALLATION
To install the XK 21 device, observe the following steps:
Position the device near the automated system to be
piloted/released. Take into consideration the overall
dimensions shown in Fig. 1;
Fig.3 shows the rear of the device, indicating the slot for
routing the electric cables ( ref.
) and the housing
of the traction cable for manual release ( ref.
);
Use XK 21 to mark the on-wall references of the holes,
as shown in Fig.4 ref.
;

IMPORTANT: Make sure that the hole for
routing the electric cables and the release
cable, has a diameter of not less than 20 mm
and is positioned as shown in Fig. 4 ref.
Secure the device on a wall;
Connect the electric cables coming from the
automated system to the relevant terminal-boards
of the microswitches (Fig.5) according to the type of
command:
NO
= Normally OPEN
NC
= Normally CLOSED
C
=
COMMON
ref.
= EARTH cable fitting
IMPORTANT: It’s forbidden to use the XK21 as
electric shunt box!
Fit the release cable, without a sheath, inside the
hole as shown in Fig. 6 ref.
, crossing also over the
tensioning device ( ref.
);
Before you tighten the release cable on the tensioning
device, take the device to the travel limit, as shown in
Fig. 6 ref.
, turning the head of the adjusting screw
with a hexagon wrench;

Make sure that the door of the XK 21 device
is kept open by the red Locking Lever
ref.
in Fig.2, before tightening the cable
on the tensioning device.
Using a pair of pincers, apply tension to the cable
WITHOUT RELEASING the connected OPERATOR, and
then tighten the release cable on the tensioning
device with the relevant screw;
Turning the head of the adjustment screw with a
hexagon wrench, move the tensioning device until
you release the operator, connected as shown in
Fig. 7 ref.
;
Cut excess cable at the exit of the tensioning
device;
If it is not present, fit the lock, conforming to standard
DIN 18252 on the front of the XK 21 device as shown
in Fig. 8;

Fasten the lock, inserted as above, with the supplied
plate and screws ( Fig.8 );
Join the front part to the part secured to the wall,
tightening the four self-forming screws as shown in
Fig. 9 ref.
;
Check activation of the microswitches, turning the key
in the lock according to the diagram in Fig.10:
A =

IMPORTANT:
Check if
position C corresponds
to the disappearance of the piston
ref.
in Fig.9, inside the body of the
device.
When you have checked the activation of the lock
release piston, remove the safety plug from the release
lever as shown in Fig. 11;
