6.2 Main Rectifier Modes
In addition to Main Rectifier States, there is a set of Main Rectifier Modes. These modes can be divided into two
categories as follows:
6.2.1 Output Voltage Modes
Voltage modes can be thought of as modes that, under software control, can directly adjust the output voltage.
The qualification of ‘under software control’ is made because there are processes that occur in the rectifier that
can change the output voltage that do not adjust the output voltage directly (such as the rectifier being in current
limit).
The following table lists the five Output Voltage Modes and a description of when they are active:
Output Voltage Modes Active when…
Float Output voltage is set to the float voltage setting.
Equalize Output voltage is set to the equalize voltage setting.
Battery Test Output voltage is set to the battery test voltage setting.
Safe Output voltage is set to the safe mode voltage setting.
Manual Test Output voltage can be manually adjusted outside of the standard adjustment ranges.
Table A–Output voltage modes
6.2.2 Output Current/Power Modes
These modes directly affect the output current and power.
The following table lists the four Output Current/Power Modes and a description of when they are active:
Output Current/Power Mode Active when…
Temperature foldback mode Output current and power limit have been reduced due to high temperature of the
heatsink or internal ambient temperature sensor.
AC foldback mode Output current and power limit have been reduced due to low AC input voltage. Note:
this will reduce the risk of tripping an AC breaker due to increased AC current draw as
the AC voltage decreases.
Short circuit foldback mode Output current limit has been reduced due to a short circuit at the output.
Internal fault foldback mode Output current limit has been reduced due to an internal fault.
Table B–Output current/power modes
6.3 Can Bus Communications
The CAN bus is used for communication between the rectifier and CXC.
The communication between the rectifier and CXC consists of commands and data transfer that are used during
the operation of the power system to configure the rectifier with system settings and to monitor rectifier status.
