Alarm LEDs and Buon Status Descripon
Major alarm LED
Red Indicates a crical condion that can cause the switch to stop
funconing. Possible causes include component removal,
failure, or overheang.
Minor alarm LED
Yellow Indicates a serious but nonfatal error condion, such as
warning for a maintenance or a signicant increase in
component temperature.
Alarm cuto/lamp test buon
– Deacvates major and minor alarms. Causes all LEDs on the
cra interface to light (for tesng) when pressed and held.
Alarm Relay Contacts
The cra interface has two alarm relay contacts for connecng the switch to external alarm devices.
Whenever a system condion triggers either the crical (major alarm) or warning (minor alarm) alarm on
the cra interface, the alarm relay contacts are also acvated. The alarm relay contacts are located on
the upper right of the cra interface.
