The Scheme Of Xlogic - Rievtech xLogic ELC Series User Manual

The fans are monitored by means of flow sensors. If no air flow is registered after a short delay time has
expired, the system is switched off and an error message is generated, which can be acknowledged by
pressing the off button.
Fan monitoring requires an analyzer circuit with several switching devices, in addition to the flow sensors.
A single xLogic device can replace this analyzer circuit.
