WARNING
Continuous operation
Devices up to E01/V1.0.0:
In continuous operation for PL e/Cat. 4 in accordance with ISO 13849-1 or SILCL 3 in accordance
with IEC 62061, the key safety values apply where the function test interval (state change of
the outputs) ≤ 1 year.
Devices from E02/V1.1.0:
In continuous operation for PL e/Cat. 4 in accordance with ISO 13849-1 or SILCL 3 in accordance
with IEC 62061, the key safety values apply where the function test interval (state change of
the outputs) ≤ 20 years.
