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 r elay: 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 m achine stops immediately, and automatic restart when the power
supply returns is inhibited. Another function is that of resetting the thermal relay
provided t o 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.
