CONTROLS
The auxiliaries off state (6) is useful for longer stop of the machine but not
for maintenance purposes. Example: operator change of shift, wait for
material arrival, misc. delays.
The state of machine standstill after emergency stop (7) is a transient state
but it can be used in some exceptional cases also for quick checks. Anyway
we recommend always to switch the machine off by opening the main
breaker when maintenance operations are required.
From the point of view of operator's safety also the states have been listed
according to a decreasing level of danger.
States and modes standard sequence at machine power up is the following :
cabinet power up – 7 – (4) – 6 – 3 – 5 – 1 where mode 4 is present if the
photoelectric barrier has been installed.
States and modes standard sequence at the machine switch off is the
following :
5 – 3 – 6 – cabinet switch off.
3.1.1 Video and CNC Push Button Stations
a
Video: colour LCD 12.1" display
b red mushroom on yellow disc push-button with mechanical reset, for
emergency stop
It is always active in all machine states or modes and in whichever of
their phases. It causes the safe stop of all the machine movements and
of the hydraulic power pack; all the CNC outputs are set to zero. The
machine is set in the state of machine standstill after an emergency stop
(this is the same state in which stays the machine at power up). The
difference between the auxiliaries off state (6) and this one is that the
servomotors drives are not fed (supply side) and to restore operations it
is necessary to reset the safety module for the emergency stop pressing
the relevant push-button.
