Macurco CX-xx Manual (Rev-1.0) Eng
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 CX-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 CX-6 display will flash the error.
*See section 4.5.14 Select Trouble Fan Setting – "tFS" for options.
