- is a mechanism that is activated for prevent your house fires
-where is it?
-normally, is in the house entry.
-Getting back theme, how the grinding machine work?
-The grinding machine have a  esmeril rock, and a security system, the rock movement is rotating.
-can i use any esmeril rock?
- no you can`t, it depends of the work to be performed.
-can i polish the edges of a table?

KSD - Switch Disconnector










The KSD is designed to operate as part of an integrated safety system, controlling access to hazardous areas. Typical machinery using the KSD range are motor driven, high risk applications where complete isolation of the power supply is required before access is granted. The removal of the key in the KSD changes the condition of the electrical supply to the machine to a safe condition. This key can be removed and used to unlock the door via AIE access interlock. The guard can only be opened when the electrical supply has been switched into a safe condition. The machine cannot be restarted until the door is closed and the key is removed and taken to the KSD.

Salus20 - Key Isolator Switch









A typical application of Salus20 isolator key switch is machine guarding. It is usually used in combination with an access interlock such as the Salus for part body access or an access interlock with an exchange key for full body access control such as AIE. The Salus20 breaks the machine safety circuit, ensuring a machine is shut down when the key is turned and removed. The key can then be taken to the Salus automatic access interlock to enable access to the machine. The machine cannot be restarted until the door is closed, the bolt is trapped in the access interlock and the key is removed and taken to the Salus20.

KS - Powersafe Electrical Switch








A typical application of KS powersafe electrical switch is machine guarding. It is usually used in combination with an access interlock such as the Salus for part body access or an access interlock with an exchange key for full body access control such as AIE. The KS breaks the machine safety circuit, ensuring a machine is shut down when the key is turned and removed. The key can then be taken to the Salus automatic access interlock to enable access to the machine. The machine cannot be restarted until the door is closed, the bolt is trapped in the access interlock and the key is removed and taken to the KS.

KSE - Multi-key Powersafe Electrical Switch







A typical application of KSE multi-key powersafe electrical switch is machine guarding. It is usually used in combination with an access interlock such as the Salus for part body access or an access interlock with an exchange key for full body access control such as AIE. A typical system will isolate machinery and control access to hazardous areas. Removing the power isolation key from the KSE unit changes the condition of the electrical supply to the machine to a safe condition and enables the release of the personnel keys. These keys are then used to unlock the AIE dual key access interlocks. The guards can only be opened when the electrical supply has been switched into a safe condition and only once all the keys have been returned to the KSE can the machine be restarted.

KSS - Solenoid Controlled Switch








A typical application of KSS solenoid controlled switch is machine guarding. It is usually used in combination with an access interlock such as the Salus for part body access or an access interlock with an exchange key for full body access control such as AIE. The KSS breaks the machine safety circuit ensuring a machine is shut down. Once the machine has completed the cycle, an external signal is received by the solenoid, which is indicated by an illuminated LED. Activating the green button on the KSS will enable the key to be turned and removed ensuring the power is locked out. The key can then be taken to the AIE access interlock to enable access to the machine. The machine cannot be restarted until the door is closed, the bolt is trapped in the AIE access interlock and the key is removed and taken to the KSS.

KSUPS+ - Solenoid Controlled Switch









A typical application of KSUPS+ solenoid controlled switch is the control of access to uninterruptable power supply (UPS) systems. The key is released when the UPS system gives a signal to the KSUPS+ to energise the solenoid when it is in a safe state to allow access. The key can then be taken to gain access to the protected area. The UPS cannot commence until the key is removed and taken to the KSUPS.

K - Bolt Interlock








The K bolt interlocks are used as a part of a safety system to allow safe control of valves or disconnect switches. While power supply to the system is switched on, the access doors to the hazardous area are locked closed. Key A is trapped in the disconnector K bolt interlock (1) while the process is on. To enter the hazardous area, the disconnector is turned to the OFF position and key A is released, locking the disconnector in the disengaged position. Key A is then taken to the grounding switch. Key A enters the second K lock (2) which retracts the bolt enabling the cammed switch lever to be rotated to engage the ground. Once rotated, the recess in the cam aligns with the next K lock (3) with key B trapped in its lock. Key B can now be removed from K lock (3), which now locks the lever in place ensuring that the ground connection cannot be broken. The system is now disconnected and grounded, key B can be taken to operate the access interlock on the door of the hazardous area to gain access into it.

KC - Claw Interlock








The KC claw interlock is used as a part of a safety system, typically in machine guarding applications. It is usually used in combination with an access interlock such as the Salus for part body access or an access interlock with an exchange key for full body access control such as AIE. While the power supply is switched on, the key is trapped in the KC claw interlock. To lock off the power supply switch, manually drive the bolt to extended position. This will release the key keeping the bolt extended and the switch locked off. The key is released and taken by the personnel to unlock the AI access interlock on the access door. While the access door is opened, the key remains trapped in the AI lock. The system has to be designed so that the bolt of the KC claw interlock cannot be retracted to unlock the power supply until the door to the machine is locked, the key removed from AI access lock and the replaced into the KL claw interlock.

KP - Bolt Interlock with Safety Switch









KP bolt interlocks with safety switches are used as a part of a safety system, typically in switchgear applications. The electrical supply of the machine is on, and the protective door to the hazardous area is locked. The key is trapped in the KP bolt interlock. Before entering the machine area the disconnector lever needs to be rotated to isolate the machine. To lock the disconnector lever in the safe position the key in the KP bolt interlock needs to be turned extending the bolt of the KP. Removing the key traps the bolt in the extended position. The operation of the KP also changes the contacts in the KP switch. This is connected to a traffic light or another display, indicating the access to machine area can be gained. The removed key is taken to the AI access interlock to open the door. The power supply cannot be switched back on while the key is trapped in the access interlock.

FS / Q - Switchgear Interlock









The FS/Q locks are used to ensure that multiple supplies are not applied to common bus bars. When all incomers are closed the bus bars are open. To close a bus bar, first the incomers must be switched to open. In the shown is application to close Bus 1, either incomer AA or AB must be opened. The key is removed from either AA or AB connection and is then inserted into the bus switch A_ (A BLANK). To close Bus 2, either incomer AB or BB must be opened and the key AB or BB transferred to the switch _B (BLANK B).

This is my presentation about what I do in the week.

First I wake up and get out of my bed at four o'clock, i don't like rise early, ironing my clothes. Later I have a shower, seen me and front of the mirror combing my hair but i dont like iron it hair. After I'm go to the kitchen and I have a breakfast because my mother does not cook for me, and then I'm clean my teeths. Later I grab my things and get in the bus, I'm in class of industrial mechanics at six o'clock to one o'clock. I come back to my home, I listen to something music, eat lunch, I sit down in the table for study. More later I cook dinner, and I eat with my family. Clean the dishes. After I play call of duty in computer, I don't like when i dead in the game, after I watch tv and then I'm go to sleep. The saturday I'm with my family and sundays I go to walk.

see you later my friends, this isn't it !!
