samos Safety System

System Functions

The

samos

safety system is for monitoring sensors as part of the safety equipment of

machines. The safety function (e.g. an emergency stop function) is implemented by
switching outputs

on or off safely in relation to the state of the sensors on inputs

(enable) and

(Reset condition). Switching these outputs on/off prevents dangerous states

occurring in the plant/ machine.

The safety function is made up of a chain of logically linked functions. The input

modules communicate with the associated base module (on the left) via the internal safety
bus (SBus). The relay output modules are not integrated directly via the SBus in the

samos

safety communication system. However, indirect monitoring is possible via the feedback
circuits.



Input circuit function

The input circuit function logically links input signals for further processing. There are
different methods for activation:



Input circuit function single-channel via NC contact



Input circuit function with dual-channel equivalent activation,
with/without cross-circuit monitoring, with/without synchronous time monitoring



Input circuit function with dual-channel non-equivalent activation,
with/without cross-circuit monitoring, with/without synchronous time monitoring



Two-hand function with activation by one NO contact per hand (EN 574, IIIA)



Two-hand function with activation by NO/NC combination for each hand (EN 574, IIIC)



Dual-channel equivalent activation by semiconductor
