IDEC SmartRelay User’s Manual
Flow sensors monitor the fans. If, after a short delay, no
airflow is registered, the system is switched off and a fault
reported. Acknowledge this by pressing the stop switch.
Monitoring the fans requires an analyzer circuit with several
switching devices in addition to the flow sensors. A single
IDEC SmartRelay module can replace the analyzer circuit.
