Operation Description
Power Up -
The unit will not operate until all the inputs and
safety controls are checked for normal conditions. The unit
has a 5 to 80 second random start delay at power up. Then
the compressor has a 4 minute anti-short cycle delay after the
random start delay.
Standby
- In standby mode, Y1 abd Y2 are not active. The
compressor will be off.
Dual Compressor Cooling, 1st Stage (Stage 1, B) -
The stage 1
compressor will be staged to full capacity 20 seconds after Y1
input is received at the ABC A board.
Dual Compressor Cooling, 2nd Stage (Stage 1, Stage 2, B) -
The stage 2 compressor will be engaged to full capacity 30
seconds after Y2 input is received at the ABC A board.
Other Modes of Operation
Emergency Shutdown -
Four (4) seconds after a valid ES
input or communicated signal, P2-7 is present, all control
outputs will be turned off and remain off until the emergency
shutdown input is no longer present. The fi rst 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 or communicated signal 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. These feature can be applied to Circuit A or B
individually.
Aurora ‘Base’ Control LED Displays -
Although the
HydroLink2 Aurora comes with a 10” color touch tablet, the
ABC does have LED’s for reading basic status and fault codes.
These three LEDs display the status, confi guration, and fault
codes for the control. These can also be read in plain English
via the HydroLink2 Touch Display.
