ATTENTION!
Do not open/remove any protection guard and/or deactivate the safety devices for any reasons,
unless in case of real need and in adopting previously all necessary measures suitable for eliminating the
risks related to or to reducing them as much as possible
.
These measures are to be carried out by qualified and authorized personnel only. Re-assemble the guards
and fix them by using the suitable fixations means and re-activate the safety devices as soon as the reasons
for their temporary removal /deactivation are ceased. Whoever does not observe the instructions above
mentioned is fully responsible for any eventual direct or indirect damage to people, animals, things which
may occur .
5.2.3
SAFETY EQUIPMENT EFFICIENCY CONTROLS
The efficiency and the integrity of the safety equipment described in par.5.2.2, have to be checked at the
beginning of each work day and/or shift as follows:
1
Movable bowl cover check related to safety microswitch
The check is to be carried out with empty bowl. Operate the start of the machine and wait it to switch in 2
nd
speed operating; lift up the cover very slowly and stop as soon as the microswitch clicks ; then:
- check the microswitch to operate the emergency button of each gear in motion when the cover is far less
than 75 mm from the upper edge of the bowl (75 mm is not an acceptable value)
- check that in the models no. SPI 30 - 45 - 60 the spiral and the bowl stop within 4 seconds from the click of
the microswitch (check by means of a chronometer; in case of doubt, the check is to be carried out by
using an oscilloscope done by a qualified and skilled electrician), instead, for all other models the stop has
to be instantaneous due to the brake system they are equipped with.
- check that, on the microswitch conditions described above, it is not possible to carry out any start command
Should the control result negative, do not use the machine and contact immediately a qualified
technician skilled in board machine electrical equipment.
2
Fixed Covers
Check visually that all guards are at their place, and in a good state (without dent or break etc.) and fixed
through suitable fixation means.
Every time a fixed cover is disassembled ,
check that the screws, used to
hold it fix in position, remain and do not release from the cover.
Should the control result negative, do not use the machine and contact immediately a qualified
engineer skilled in machine assembly; in case of need, contact the manufacturing company.
3
“Dead man” button for open cover bowl rotation
Open the cover and keep the button (21) pressed, for
M
Version, or (13), for
E
Version. When the bowl is in
motion, check that it rotates at the slowest speed (1
st
speed); release the button: the bowl has to stop.
Should the control result negative, do not use the machine and contact immediately a qualified
engineer skilled in machine assembly; in case of need, contact the manufacturing company.
4
Emergency stop button check
The check is to carry out with empty bowl. Operate the machine start and wait it to switch in 2
nd
speed
operating; press the emergency button and :
- check that each gear in motion stops and the button stays in position pressed
- check that for the mod. no. SPI 30 - 45 - 60 the spiral and the bowl stop within 4 seconds from the pressing
of the button (check it by using a chronometer; in case of doubt, the check is to be carried out by using an
oscilloscope done by a qualified and skilled electrician), instead, for all other models the stop has to be
instantaneous due to the brake system they are equipped with.
- check that , by keeping the button pressed, it is not possible to carry out any start command
Should the control result negative, do not use the machine and contact immediately a qualified
technician skilled in board machine electrical equipment.
