6.1.3 Control System Power
After the LabGard® ES NU-543S is plugged into the appropriate facility line power the control system will power up
and display a power on reset message, the last revision of software (for several seconds) and time. The control
panel will also indicate the power up status by blinking the red alarm LED. Pressing any key will acknowledge the
power up status and turn off the blinking red alarm LED.
If a power interruption occurs, all control system functions, calibrations and parameters will be maintained and
continue upon restoration of power. Just as the initial power up, the red alarm LED will blink to indicate power up
status along with the display message of power on reset.
6.1.4 Standby Mode
When the BSC is not in use, the display will indicate the NuAire logo with the current time provided in the upper
right corner. Any of the function keys, except the blower that initiates run mode may be turned on and off in
standby mode. The cabinet status and main menu may also be accessed for use as needed. The display for the
FlowGard™ Control System has a screen saver built in for extended OLED life. The screen saver time is 5 minutes.
This means after 5 minutes when the blower is not on, the display will go dark. Pressing any key will again
illuminate the display.
