5.8.4 Dual-channel sensor, not monitored
Using dual-channel homogeneous sensors without pulsing can lead to problems. Short
circuits cannot be detected in the supply line of the dual-channel sensor, e.g. in the
cable. Safe operation can only be achieved by routing the cables separately and making
sure the terminals cannot short circuit.
The DCS..B option can operate safely with dual-channel diversified sensors without
pulsing.
