Safety and accident prevention 3--7
Emergency devices
In accordance with IEC 204---1Standard:
=
Chapter 5 Section 6 Sub---section 1 ”Emergency stop device”:
«the emergency stop device immediately stops all dangerous and other functions
of the machine.»
=
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 re-
start the functions, which must be reset »
...emergency devices on DM 8:
1. Emergency stop: a no--return mushroom push--button, colour red on yellow
background, is located on the control panel of the machine. To release the
push--button, the actuator must be rotated by 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.
