9.3. END FOOT
The end foot, fi g. 21, makes it possible to rest the bar when closing, thus
avoiding any downward bending of the bar.
Use of the foot involves adapting of the balance spring..
9.4. FORK SUPPORT
The fork support, fi g. 22, is used for two purposes:
• to avoid that the bar, when in closing position, bends or breaks under
the effect of outside forces.
• to make it possible to rest the bar in closing position, thus avoiding any
downward bending of the bar.
Use of the fork support does not require changes to the balance
spring.
9.4.1. P
OSITIONING THE FORK SUPPORT
To position the fork support foundation plate, refer to the measurements
shown in fi g. 23 where:
L= bar length
A= L-500mm
For correct positioning, we recommend positioning the fork support
after having completely installed the automated system. The result
will be correct positioning of the fork centre with the centre of the
bar.
9.5. BAR LIGHT KIT
For 617 3 and 4 models, a light kit is available for use on the top of the
bar. The lights increase bar visibility, especially at night.
Installation of the light kit involves adapting of the balance spring.
9.6. BATTERY KIT
For the 617 424 model, an emergency battery kit is available for positioning
inside the upright. The battery kit makes it possible to make up for electrical
power interruptions.
The battery kit cannot be used as an alternative to electrical
power.
