SAFEMASTER STS The key to more safety Modular safety switches and key transfer systems for the highest requirements. Our experience. Your safety.

SAFEMASTER STS – the ultimate safety system SAFEMASTER STS Simply revolutionary The special thing about SAFEMASTER STS is the system concept and the simple design which allows any conceivable variant, from the smallest standard solution to a complex safety system. Any solution remains flexible, unique and economical thanks to the modular design principle. Many Safety Concepts – One System Robust, economical and sustainable SAFEMASTER STS allows you to implement the most demanding safety concepts without any wiring. This saves costs, power, effort and materials. These components are...

Solenoid guard lock Safety switches A solenoid controlled guard lock secures the entrance in a hazardous area during operation and can, for instance, be disengaged for maintenance purposes. As an example, safety switches are used for electrically monitoring entrances or safety gates. It immediately switches off when the entrance is opened during the machine operation. Maintenance door Maintenance door Trapped key interlocking This guard locking device operates fully mechanically, making wiring unnecessary.The respective doors can safely be opened after inserting the key.

Hybrid System – Ergonomically safeguarding hazardous areas Hybrid system SAFEMASTER STS combines the advantages and functionality of safety switches, guard locking and trapped key interlocking in just one system For example, one can electrically monitor a main entrance that is often utilised ( ), while seldom used entrances and maintenance accesses ( , ) are secured in a fully mechanical manner by means of trapped key interlocking. Maintenance door Maintenance door Main entrance

Example Overview Zone 1 electrical / mechanical Control Main entrance panel Zone 3 fully mechanical / wireless system Service / Maintenance doors All entrances can be individually actuated and monitored. One switch can monitor multiple entrances. Before an entrance can be opened, a key must be removed. This can be used to open additional entrances or serve as a safety key. Keys can be retained until a safe state has been reached. A main entrance that is often used can monitor multiple entrances.

Lock Out Tag Out (LOTO) The padlock module offers an additional protective function – this module enables LOTO functions to be integrated into the SAFEMASTER STS system.The device is pulled and any worker who wishes to enter the facility inserts his personal padlock. Therefore, the mechanism can no longer be plugged in. None of the workers need to bring a key into the facility.The machine can only be restarted after all the padlocks have been removed and/or when all employees have left the installation. Safety key The employee must take the key with him into the facility for his own safety....

SAFEMASTER STS – Reliably control emergencies Escape and emergency release SAFEMASTER STS also allows for escape releases and emergency unlocking. People who become locked in by accident can always safely leave the facility. Furthermore, entrances can be equipped with an emergency unlock mechanism. After it is triggered, locked-in people can escape or rescued from outside. Trigger via rotary switch An entrance can be unlocked by actuating the emergency unlock mechanism. Cable pull Trigger via cable pull In case of an emergency arising from a person being locked in, the entrance can be...

SAFEMASTER STS – Everything under control with the Option Module The Option Module is a unique extension of the interlocking system for safeguarding safety gates on machines and facilities. The Option Module expands the command functions and improves SAFEMASTER STS System's connection technology. This turns a switch or a guard lock unit into a true "control centre", from which command functions, status indication, release, main and maintenance entrances can be monitored. The special multi-cables with a plug connection ensure quick and smooth, internal connection of individual components....

SAFEMASTER STS – Complex monitoring with one device Cascading not necessary Multiple interlocking devices are connected in series during cascading - this saves the trouble of wiring but errors can be erased when multiple doors are opened. If entrances must be opened at the same time, then fault exclusion is required to reach a performance level of PL d or PL e.With SAFEMASTER STS, individual units can monitor multiple entrances at the same time - without cascading, without decreasing performance levels and without fault exclusion. Zone 3 Zone 2 Zone 1 The Option Module can ideally be...

Control Interlocking – controlled safety Entrance and machine monitoring Easy and simple, but highly efficient: In control interlocking, machine or facility status is monitored by an higher level control unit, such as braking units, standstill monitors and emergency stop modules. This allows for a facility to be shut down in a controlled manner and ensures that access to the keys, and thereby access to the facility, is only granted after authorization by the monitoring system. Complies with EN ISO 13849-1 requirements Suitable for both centralised and de-centralised structured systems.

Power Interlocking – flexible and modular up to 800 amperes Safety, also without a control unit The system is directly cut off from the electrical network using a load break switch A machine's energy source is directly shut down here, without a separate electrical or electronic control level. This gives simple machines or facilities as well as retrofits the advantage of not requiring any control units. Even Category 4 PL e can be reached, when the system is properly structured. Up to performance level PL e and category 4 Emergency stop or zone stop Large switching capacity, currents from 25...
