In this application (above) the Fan or primary relay is used as a low-level alarm relay. The Alarm or secondary relay is used as a
supervisory relay when utilized in the normally closed configuration. The CM-6 monitors all critical functions of the unit
through software diagnostics that continually test and verify its operations. If a problem is found, the unit will switch to a fail-
safe/error mode or trouble condition. In this error mode the Fan* and Alarm relays will be activated indicating the trouble
condition at panel and the CM-6 display will flash the error. *See section 4.5.11 Trouble Fan Settings – "tFS" for options.
