Type IIIC
W
ith type IIIC, two pairs of complementary inputs (N/O contact / N/C contact pair) are
monitored.
A valid input signal is only generated if the ON state (High/Low level) is present at
both inputs within a period of 0.5 s (synchronous changeover, both two-hand switches
actuated) and both were previously in the OFF state (Low/High level).

WARNING
Ine
ffectiveness of the protective device due to unrecognized switching signals between
the safety sensors
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
►
Configure the test periods of the test outputs as shorter than the duration of the
switch-off condition for the safety sensors.
5.4.1.6 Diode module DM8-A4K
The diode module DM8-A4K serves as a connection adapter when multiple pressure-
sensit
ive safety mats that trigger short-circuits are connected to an FX3-XTIO or FX3-
XTDI module. It decouples test outputs X1 and X2, thus increasing them fourfold.
NOTE
T
he DM8-A4K diode module is not a safety component in the sense of the Machinery
Directive. It therefore does not have to be taken into account when calculating the
safety integrity level (SIL according to IEC61508 and IEC62061) or the performance
level (PL according to ISO13849-1).
