LS+, not L+, should be used for short-circuit protection. Each LS+ features individual
short-circuit and EMC protection that make it important to use LS+ for only it's four
related inputs.
Line Control
Line control is a short-circuit and line break monitoring system (e.g., E-Stop inputs)
which can be configured for the GuardPLC system. Up to 8 digital outputs (DO1 to
DO8) can be configured as pulsed outputs. The example below shows 2 pulse
outputs connected to the digital inputs (DI) of the same system. As a result, the
connections to the digital inputs (DI) are monitored.
