6.3 Rectifiers
This menu category consists of rectifier alarms and controls. Parameters can be set/accessed such as
float/equalize voltages, high/low voltage alarms, and start delay.
6.3.1 Rectifier Report
This feature will enable the user to view, in a list report (see 4.4.2, Figure 9), all of the acquired rectifiers in the
system. The first column lists the serial numbers of the rectifiers. The report then displays the output current of
each rectifier under the Amps column (or toggle for % of maximum output) and the number of active alarms under
the Alarms column (if that rectifier is issuing an alarm). The rightmost column displays the number of settings out
of tolerance (OOT per web interface).
Select a rectifier and tap “View Details” to produce another list showing details of the entire rectifier alarms and
settings that are out of tolerance.
6.3.2 Configure Settings
This feature will enable the user to configure settings (via menu items) for all of the acquired rectifiers in the
system.
Figure 32–Configure Settings (rectifiers) window
The menu items described below may be configured via a virtual numeric keypad (5.1.5) or by toggling the listed
item. For a basic programming example, see 5.2.
6.3.2.1 Float (FL) Voltage
This menu item enables the Supervisor to set the system BATTERY VOLTAGE (measured at
an analog input channel) to the desired float voltage value. Float voltage charges the battery
string and supplies the load. Normally, the power system will operate in the float mode. This
setting should have a minimum of LVD + 1V and a maximum of OVP – 1V.
6.3.2.2 Equalize (EQ) Voltage
This menu item enables the Supervisor to set the system BATTERY VOLTAGE (measured at
an analog input channel) to the desired equalize voltage value. Equalize voltage charges the
battery string at a higher than normal voltage to either recharge batteries after a power failure or
to balance individual cell voltages. Periodic equalizing of the battery string may be required to
optimize battery performance and life. This setting should have a minimum of LVD + 1V and a
maximum of OVP – 1V.
6.3.2.3 Battery Test (BT) Voltage
This menu item enables the Supervisor to set the Battery (Discharge) Test Voltage to the
desired value during the test (mode). This setting should have a minimum of LVD + 1V.
6.3.2.4 Safe Voltage
This menu item enables the Supervisor to set the default system voltage (Safe Mode) in the
event that communications to Cordex rectifiers should fail. See 3.4 for more details about this
feature.
