Emergency Shutdown - Four (4) seconds after a valid
ES input, P2-7 is present, all Aurora control outputs
will be turned off and remain off until the emergency
shutdown input is no longer present. The first time that the
compressor is started after the control exits the emergency
shutdown mode, there will be an anti-short cycle delay
followed by a random start delay. Input must be tied to
common to activate.
Load Shed - The LS input disables all outputs with the
exception of the blower output. When the LS input has been
cleared, the anti-short cycle timer and random start timer
will be initiated. Input must be tied to common to activate.
Aurora ‘Base’ Control LED Displays
These three LEDs display the status, configuration, and
fault codes for the control. These can also be read in plain
English via the Aurora AID Tool.

Aurora Interface and Diagnostics (AID) Tool
The Aurora Interface and
Diagnostics (AID) Tool is
a device that is a member
of the Aurora network.
The AID Tool is used to
troubleshoot equipment
which uses the Aurora
control via Modbus RTU
communication. The AID
Tool provides diagnostics,
fault management, ECM
setup, and system configuration capabilities to the Aurora
family of controls. An AID Tool is recommended, although
not required, for ECM airflow settings. The AID Tool simply
plugs into the exterior of the cabinet in the AID Tool port.
