OPERATING NOTE - 2
- TILTING one or both heads to the set measurement, while the mobile head is inside the SAFETY ZONE,
can pose safety risks (despite the fact that the acoustic-light signals are working).
- The danger risk when tilting the heads in AUTOMATIC mode is that of BEING CRUSHED between the two
heads.
- For this reason the machine has been constructed to respond as follows: The tilting movement starts at a
“reduced” speed and can be increased to normal speed by turning (and holding in place) selector “4” - Fig.
06-02: the head or both heads carry out the tilting movement stopping automatically at the final measurement
set. If the selector is released before the final set measurement, tilting of one or both heads takes place at
a “reduced” speed for safety reasons.
OPERATING NOTE - 1
- The POSITIONING movement of the mobile head to the set measurement when moving away from the fixed
head causes no safety problems (in this phase the 2 lights on the fixed head and on the mobile head roller
table flash and the acoustic-light signal activates on the mobile head).
- The POSITIONING movement of the mobile head to the set measurement when “APPROACHING” the fixed
head can cause safety problems (even though the flashing lights/acoustic signals are working).
- The danger risk when the mobile head approaches the fixed one in AUTOMATIC mode is that of BEING
CRUSHED between the two heads.
- For this reason the machine has been constructed to respond as follows:
1 - If the measurement set is less than (or equal to) 1250 mm (which defines the SAFETY ZONE), the mobile
head moves quickly towards the fixed one and “STOPS” at the safety distance.
2 - When the mobile head enters the SAFETY ZONE, the LED on selector “4” - Fig. 06-02 comes on.
3 - By turning (and holding in position) selector “4” - Fig. 06-02 the mobile head approaches the fixed head
and only stops if released or when the final set measurement is reached.
OPERATING NOTE - 3
When POSITIONING the mobile head as well as tilting one or both heads is necessary, the following situations
can occur:
- If tilting one or both heads takes place with the mobile head which, even if initially inside the SAFETY ZONE,
moves away from the fixed head, then the TILTING movement starts at the same time as MH positioning
but at “reduced” speed and can be increased to normal speed by turning (and holding in position) selector
“4” - Fig. 06-02. The POSITIONING movement when moving away however always takes place at normal
speed.
- If tilting one or both heads takes place with the mobile head which, initially being outside the SAFETY ZONE,
moves towards the fixed head with a destination measurement inside the SAFETY ZONE, then the
TILTING movement starts at the same time as positioning the MH but at “reduced” speed and can be
increased to normal speed by turning (and holding in position) selector “4” - Fig. 06-02. The POSITIONING
movement when approaching however always takes place in the same way as described in NOTE 1.
- If tilting one or both heads takes place with the mobile head which, initially being inside the SAFETY
ZONE,moves towards the fixed head, then both TILTING and POSITIONING movements can be started
by turning (and holding in position) selector “4” - Fig. 06-02. If the selector is released, the TILTING
movement takes place at “reduced” speed; on the contrary, POSITIONING the mobile head only takes place
by turning (and holding in position) selector “4” - Fig. 06-02.
