Non Critical Load Outlets On
This command controls the relay that feeds power to the NCL Outlets.
Note that if the MAIN relay is off, the outlets will still be un-energized.
Send to UPS:
NCL_ON<CR>
Action:
NCL relay closes.
Response from UPS:
NCL_OUTLETS_ON<CR> (if MAIN
relay is ON)
NCL_OUTLETS_OFF<CR> (if MAIN
relay is OFF)
Non Critical Outlets Off
Send to UPS:
NCL_OFF<CR>
Action:
NCL relay opens.
Response from UPS:
NCL_OUTLETS_OFF<CR>
Set Low Battery NCL (Non-Critical Load) Shutoff
It is desirable to allow the user to set the battery storage threshold in
which the non-critical load outlets will shut off therefore reserving the
remaining battery charge for the critical equipment. If the battery
charge falls below the threshold, Non Critical Load Outlets are turned
OFF.
A common example of critical equipment would be a projector. It is
critical that power be maintained to a projector to allow its fan to run
and cool the bulb. If the bulb is allowed to overheat, it will be damaged
and is very expensive to replace.
Send to UPS:
BATTHRESH<SP>XX<CR>
<SP> represents a space: 20 Hex
XX is a number between 25 and 60
represented in ASCII.
If XX is a valid number, between 25 and 60:
Action:
Assigns the battery threshold variable
with the value XX
Response from UPS:
BTHRESH<SP>XX<CR>
If XX is not valid:
Action:
None
Response from UPS:
INVALIDCMD<CR>
Enable Audible Alarm
It is important that the UPS be as quiet as possible as it will be located
in a home theater environment. It is desirable to control the warning
beeper. The default setting for the alarm is OFF.
Send to UPS:
BEEPON<CR>
Action:
The beeper will sound when running
from battery.
Response from UPS:
BEEPISON<CR>
Disable Warning Beeper
Send to UPS:
BEEPOFF<CR>
Action:
The beeper will not sound when running
from battery.
Response from UPS:
BEEPISOFF<CR>
Restore Default Settings
Send to UPS:
RESTORE<CR>
Action:
Set Non-critical load threshold (2.5)
to 66%
Disable the warning beeper (2.7)
Set High Voltage Failure Threshold to
147V (2.8)
Set Low Voltage Failure Threshold to
88V (2.9)
Set Battery Mode Voltage to 120V (2.10)
Response from UPS:
DEFAULTSRESTORED<CR>
QUERIES
Request Outlet Status
Transmit the ON/OFF status of the outlet banks.
Send to UPS:
?OUTLETSTAT<CR>
If NCL Outlets are ON:
Response from UPS:
NCL_OUTLETS_ON<CR>
If NCL Outlets are OFF:
Response from UPS:
NCL_OUTLETS_OFF<CR>
If CL Outlets are ON:
Response from UPS:
CL_OUTLETS_ON<CR>
If CL Outlets are OFF:
Response from UPS:
CL_OUTLETS_OFF<CR>
