Dynamization - IDEC HR6S-DN Instruction Manual

Dynamization

Dynamization of Inputs
Dynamization is used for cross circuit detection between two safety-related inputs or between one
safety-related input and the Start input or a cross-circuit to an external power supply unit or to
ground. Dynamization is implemented by means of periodically generated test pulses at the control
outputs of the safety-related inputs S#1 and of the start input Y1.
Whether dynamization of the safety-related inputs is used depends on the selected application
(see page
function
The following diagram illustrates the dynamization principle and timing:
The diagram presents the input channels S11-S12 and S21-S22. The remaining input channels
S13 and S23 as well as the remaining safety-related inputs S31-S32-S33, S41-S42-S43, S51-S52-
S53, and S61-S62-S63 use the same logic as the input channels and safety-related inputs
illusrated.
The same logic applies to Y1 and Y2.
