SAFETY INTERLOCKS AZM AND MZM
A safety interlock from the AZM or MZM series prevents rotary, lateral and removable guards, such as covers, grids and doors, from being opened until hazardous states have been eliminated. These include, for example, overrunning movements of chains, rollers or shafts. The guard locking devices work together with safety relay modules and safe standstill monitors or timers. Outside of occupational safety, a solenoid interlock is also used where the opening of a safety guard is not desired. In the area of process protection, this can mean unauthorised or undesirable interference in the production process.SOLENOID INTERLOCK: STRUCTURE AND MODE OF ACTION
The Schmersal Group relies on the concept of the ‘separate actuator’ for every safety interlock. This will be illustrated using the example of a safety door: The actuating element of the solenoid interlock is attached to the door itself - i.e. to the moving part of the guard. The guard locking, on the other hand, is permanently mounted on the post of the safety door. If the door is now closed, the operating element ‘disappears’ with it; the solenoid interlock blocks the safety door with a bolt. The machine can only be started in this state. The position of the locking bolt is constantly monitored. When unlocked, the actuator is disconnected from the basic device when the safety guard is opened. This automatically opens the normally closed contacts and closes the normally open contacts.
VARIOUS ACCESSORIES FOR SOLENOID INTERLOCKS
Solenoid interlocks have been part of the Schmersal Group's core programme for decades. The range of series and designs is correspondingly extensive. Various actuators and accessories are also available. These include door catches for pre-positioning, plug-in connections and safety screws. Models with ATEX certification and versions with integrated AS Interface Safety at Work are also available. Detailed information on accessories and each individual solenoid interlock can be found in the Schmersal online catalogue.
