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 GD-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 GD-6 display will flash the error. *See the
Trouble Fan Setting Option.
