In addition to the System manual, observe the following documents: n Drawing of the sensor equipment (optional) n Wiring schematics (optional) SSZ-GmbH is not responsible and accepts no warranty claims for damages due to failure to observe the installation instructions. 1. Intended use SSZ-Safety-Units are logic systems to assure safety functions (App.

Page 6 Due to the hose shaped special profile the internal conductive layers are held at a distance. However, due to the material used with these specific advantages the conductivity is limited. The result is that the transducer is operated in combination with a SSZ-controller. Sensor element The conductive layers of the sensor element which are depicted in a dark colour in picture 1 can be regarded as non-isolated resistor.
Page 7 System If the sensor element is not in use currency will flow from connection 3 to connection 5 as well as from connection 4 to connection 6. This leads the relay K1 and K2 to close their contact and therefore activate the output. To obtain a secure output signal the contacts of relay K1 and K2 have to be switched in sequence.
Page 8 System Several transducers can be connected to a SSZ-controller. To function correctly all transducers connected to one controller have to form a sequence. If incorrect connections are made the device may not function correctly ! If the transducers are connected parallel a cable disconnection cannot be detected by the controller.
Page 9 System Note n Only sequence switched safety transducers are permitted, as parallel connections can lead to system errors and the activation of individual transducers cannot be identified correctly. n The controllers must only be used in a room with a minimum protection of IP54. n The correct functioning of the systems must be checked at least once a day.

Page 37: Application
Large safety mats should always be transported by two people. Application SSZ-safety mats are area coverage with integrated sensor element and can only be operated with SSZ-controllers. SSZ-safety mats safeguard dangerous working areas on machines and plants and prevent or at least reduce injuries and damages.
Page 38: Types
SSZ-safety mats are manufactured according to customer specification up to a maximum size of 4.5 m² (3000 mm x 1500 mm). To safeguard a larger area than 4.5 m² it is possible to fit more than one SSZ safety mat together. One controller can control a maximum of 4.5 m² safety mat area.
