indications regarding right/left installation are seen from the
place of installation, i.e. from the inside looking out!-Unless
stated otherwise, all measurements are in millimetres.-This manual
needs to be carefully stored.-We reserve the right to modify
specifications without written notice.
2.1 Safety requirements regarding installation, use and
maintenance
-The garage gate may only be installed, connected and
commisioned by skilled personnel. -When working on the electrics,
always ensure the power is and remains isolated!
-L-angles and guide tracks must be designed and fixed to a
construction or stone wall in such a way that theyare strong enough
to be able to carry the force if a cable breaks.-This cable break
protection should never be bypassed.
-Never operate the sectional gate if you see that this cable
break protection is damaged.-During installation / maintenance of
the cable break protection, wear at least gloves, safety shoes and,
when drilling, safety goggles!-Secure the installation /
maintenance site using an appropriate safety device to keep others

3. General
A cable break protection device prevents the door panel from
falling. A blade is inserted into the running track toprevent the
door panel from falling. The cable break protection device is
triggered immediately upon a cable breaking.

4. Scope of application
The cable break protection 25453 and 25453-A are used in hand,
chain, or electrically operated sectional gates.The difference
between versions 25453 and 25453-A consists of a different hole
pattern in the mounting plate(see 11).Max. door weight: 44 -
450kg
The maximum cable diameter is: 5 mmThe guide tracks should be of
the 2 type. (Also see 7: Guide track specifications) The rollers
should be of the 2 type (46mm), with shafts 11mm thick. If the
cable break protection roller reaches the bend, the inside radius
should be a minimum of R=381.
5. Working principle
When a cable breaks, the tension in the steel cable is released.
This causes the spring of the cable break protection topush the
blade module against the guide track. The blade cuts into the guide
track and stops the door panel.

6) Now tension both steel
cables (L+R) equally. Thisis achieved by tightening the nuts.
See figures to the right.
7) Tension the springs.8) Slowly push the door panel upwards and
make sure the blades of the cable break protection do not touch the
bend. See figures below.
9) An electrically operated door should be fitted with a micro
switch (25445). Take the safety cover and fit the switch as in the
figures below. Pay attention to the cable guide.
10) Push the safety cover onto the underside of the cable break
protection and secure the cover using a Parker screw (14017). Pay
attention to the cable guide.CAUTION! The tape aroundthe blade
should not be removed!Its purpose is to prevent injury and to
determine whether the blade has been triggered!
EN V2.05 SC Milca

7. Guide track + offset specifications
When using a 40mm panel, an offset of 33mm should be used.RVS
guide tracks may not be used.
8. What should you do if a cable break is triggered?
1) Secure the door panel using struts or the fork of a forklift
truck so the door panel is prevented from fallingfurther.2) Lift
the door panel up until the blade is freed from the guide track and
the rotation module can be turned back.3) Block the rotation
module.4) Bring the door panel down in a controlled manner. 5)
Remove the cable break protection completely (when triggered, it
should be replaced in its entirety).6) Remove the sharp burr in the
guide track and check the whole door for deformation, pay special
attention torollers and guide track, and replace if necessary!7)
Install a replacement cable break protection in accordance with
this manual.
9. Testing the cable break protection
In accordance with CE regulations, sectional gates should be
checked yearly.The maintenance engineer should check the
following:1) Check whether the tape has been damaged. This could
mean the blade rubs against the guide track.2) If the blade is
damaged, the entire cable break protection unit should be
replaced.3) For electrically operated gates, check whether the
micro switch activates and check the rotation of the module.
10. Maintenance
Cable break protection units should not need maintenance.The
only thing that can be done is remove dirt.
