Emergency devices
In accordance with Standard CEI 204---1:
H
Chapter 5 Section 6 Sub--section 1 “Emergency stop device” : «the emergency
stop device immediately stops all the dangerous and other functions of the
machine»;
H
chapter 6 Section 2 Sub--section 4 Point 7 “Protective guards”: «the removal of
protective guards designed to prevent access to dangerous parts or zones causes the
machine to stop immediately; replacing the guards does not restart the functions,
which must be reset».
...Emergency devices applicable to the SHARK 282:
1. Emergency stop : a non---return mushroom---head pushbutton, colour red on
yellow background, is located on the control panel of the machine. To release
the pushbutton, the actuator must be rotated 45° . After the emergency
situation has been resolved, the machine must be reset.
2. Automatic thermal---magnetic cutout switch with thermal---magnetic relay:
the machine auto switch, located on the control panel, has two protection
systems against voltage drops. In the case of a voltage drop, all electrical
components are disengaged, the machine stops immediately, and automatic
restart when the power supply returns is inhibited. Another function is that of
resetting the thermal relay provided to protect against overcurrents.
3. Pressure contact for monitoring blade tension: the machine stops
immediately if the blade breaks or if the tensioner cylinder pressure drops.
4. Protective guard for blade: a coded key microswitch is operated if the blade
cover is accidentally or intentionally opened during the machine operating
cycle, immediately shutting down all functions.
