8k2
While in the idle state, the resistance between the two connections is approximatel�� 8.2k kW. If actuation
of the safet�� edges is reported, the resistance is less than 100 W. In the event of a fault or interruption
of safet�� edges, the resistance is greater than 100 kW.
6.1.6 Variant R
Control output via semiconductor rela��
Semiconductor
rela��
In order to perform an externall�� requested test in accordance with categor�� 2, this variant is alwa��s
combined with variant T (test).
6.1.7 Variant T
An externall�� requested test can be performed via three connection cables. The polarit�� and test
request are set according to the configuration of the connection cable with voltage.
