5.3.3. Configure basic DC system settings
TheConfigure System pagehasthreetables(Configuration,System Properties,andAlarms)with
somebasicsettingsthatmustbeconfigured.
To configure basic DC system settings (from the main dashboard):
1. GotoSystems > DC System > Configure System.
2.
IntheConfiguration table:
a. Setthesystemname,description,number,andserialnumber.
b. Setthefloatvoltagesetting.Thisisthedesiredoutputvoltageoftherectifierswhenthe
systemisinfloatmode.
c. Setthesystemvoltagesource,whichisthevoltageusedtocontrolthesystem.Thisisthe
inputoftheADIOmodulethatmeasuressystemoutputvoltage,andisusuallythesame
inputasthebatteryvoltage.
3. IntheAlarms table,configuretherelatedalarms.
5.3.4. Configure dynamic thresholds for output voltage alarms
BoththeHighandLowOutputVoltagealarmscanuseadynamicallyadjustedthreshold.ThisAdjusted

VoltagetotheconfiguredLimit.TousedynamicallyadjustedthresholdsforanOutput voltage alarm:
1. GotoSystems > DC System > Configure System.
2. IntheAlarms table,selecttheGO TO buttonfortheOutput Voltage alarmtoconfigure.
3. UsethedropdownmenutosettheAbsoluteorAdjustedfieldtoAdjusted.
5.3.5. Configure the rectifiers
Thesearesettingsthatincludestartdelay,safemodevoltage,orover-voltageprotectionthreshold.
Notice: The Safe Voltage is the voltage that the rectifiers default to if they lose communication
with the controller. This feature has a time delay that varies according to rectifier. Most rectifiers
revert to Safe Mode after five minutes. Check the rectifier manual for a list of the default
parameters.

To configure the rectifiers:
1. GotoSystems > DC System > Inventory > Rectifiers > Configuration.
2. Setupyourrectifiergroupconfigurationsettings.Theseinclude,startdelay,safemodevoltage,or
