9.2 - Scheduled replacements
The components that make up the ALT automation system have
been designed to last, under normal conditions of use, for the entire
working life of the product without any special action being required.
However, some of them are directly linked to system safety and the-
refore, it is recommended to regularly replace them according to the
following indications:
1. Replace the balancing spring(s) every 2 years or every 200,000
opening/closing cycles
2. Replace:
- the aluminium bar AST3F, ASTL4, ASTL4J, ASTL6, ASTL6J every
5 years or every 500,000 opening/closing cycles
- the aluminium bar AST3F, ASTL5, ASTL8, ASTL6J every 3 years or
every 250,000 opening/closing cycles
- the articulated bar AS-SNO3 every 2 years or every 150,000 ope-
ning/closing cycles
3. Replace the gearmotor every 5 years or every 500,000 opening/
closing cycles
clean their front surface (do not use solvents).
18. Check the eciency of the LED ashing lights integrated in the
barrier body and the integrity of the transparent covers.
19. Check the integrity and eciency of any accessories installed:
APM mobile support, APFX xed support, SKIRT2 racks, joint for
articulated bar, etc. Make sure that they are rmly secured.
20. Check that the automation system is working properly and that
the bar motion is smooth. Ensure that the opening and closing
speeds are adequate for the length of the bar, with gradual accele-
ration in the initial phase and progressive slowing down in the nal
phase of the travel, in order to avoid dangerous jolts and swaying
that could aect the safety and life of the bar.
21. Ensure compliance with the regulation provisions, in particular
the requirements relating to user safety contained in the EN 12453
standard (see paragraph 8.1 "Testing")
