The Safe-E-Stop™ by Cattron is a SIL 3 wireless e-stop system that enhances safety by allowing an individual or a group of operators to respond to an emergency without the delay typically associated with moving to a hard-wired E-stop station. Safe-E-Stop includes a personal safety device worn on a waist belt, providing constant access to a wireless emergency stop. It can be used with overhead cranes & hoists, conveying systems, on and off-highway mobile equipment, manufacturing, transportation and warehousing.
The chance of failure must be minimal. From a technical point of view, it is not surprising that many people consider the emergency stop button as the safest solution. Are the conditions in which your fitter/mechanic does maintenance or repairs really always safe? Can he/she easily reach the emergency stop button in case of an emergency?
Gain valuable seconds
The fixed wired E-stop is usually mounted on the machine. In some situations every second counts, these precious seconds can be gained by using the wireless emergency stop. The person concerned could find himself in a difficult situation, being unable to reach the emergency stop button due to distance or being trapped, with all the consequences that follow. With the Tyro Remote Wireless emergency stop you anticipate these risks and thereby gain life-saving seconds.
Safety at schools
Also at schools the wireless emergency button ensures improved safety. The practical teacher cannot spend too much time on a pupil operating a machine, he gives advice, answers questions and generally does his rounds during the lesson. If an emergency occurs, the pupil could panic and not always know what to do. With an extra wireless emergency stop you anticipate and eliminate these risks.
Out of range protection
To prevent a false sense of security it is imperative that the system verifies that communication between the wireless emergency stop and the receiver is possible. Only in that case is it possible that another emergency stop signal can be given.
Redundant circuits
Build up the hardware determines Performance Level. At Performance Level c a single and a double fault can be recognized by the system so that the safety function is not compromised.
Technology
To achieve this, use is made of a redundant set up system, 2 processors are checking each other continuously to verify that there are no defects or errors.
Redundant relays with forced contacts
By applying these relays dangerous faults such as sticky contacts can be recognised safely. To further increase this safety the relays are doubled (redundant).
Safety relays with forced contacts are used for installations that have a limited amount of safety functions and realise logical couplings, such as the emergency stop button.
Each emergency stop a unique ID
To prevent a receiver reacting to each radio signal on the right frequency, each wireless emergency stop is tuned to the receiver in advance. When a number of radio-graphically operated machines are next to each other and ID codes are not used it can result in machines reacting to the wrong signals. This is obviously creates a risk.
56-bit ID Safety Code
The Indus Gemini features a 56-bit ID Safety Code; with which countless combinations are made possible, resulting in an almost non-existent chance of the same specific coding with two transmitters simultaneously.
