n Activating a vent fan to disperse hydrogen from the battery compartment when
the batteries reach their gassing voltage.
Low array voltage (LowArrayV): Activates the auxiliary output when the PV array
voltage falls below the trigger setting for the trigger delay time. Deactivates the auxiliary
output when the PV array voltage rises above the clear setting for the clear delay time.
High array voltage (HighArrayV): Activates the auxiliary output when the PV array
voltage rises above the trigger setting for the trigger delay time. Deactivates the auxiliary
output when the PV array voltage falls below the clear setting for the clear delay time.
Use this setting if you want the auxiliary output to control a series latching relay to
disconnect the PV array from the charge controller or trigger an alarm when the PV array
voltage exceeds the trigger setting (the charge controller’s maximum operating voltage is
550 VDC).
Low battery temperature (LowBattTemp): Activates the auxiliary output when the
battery temperature falls below the trigger setting for the trigger delay time. Deactivates
the auxiliary output when the battery temperature rises above the clear setting for the
clear delay time. Battery temperature is measured with a BTS. Do not use this setting if a
BTS is not installed. With this setting, the auxiliary output can turn on an indicator alarm if
the batteries are too cold. A battery with frozen electrolyte will not accept a charge.
High battery temperature (HighBattTemp): Activates the auxiliary output when the
battery temperature rises above the trigger setting for the trigger delay time. Deactivates
the auxiliary output when the battery temperature falls below the clear setting for the clear
delay time. Battery temperature is measured with a BTS. Do not use this setting if a BTS
is not installed. With this setting, the auxiliary output can turn on a fan to cool the battery
compartment.
High heat sink temperature (HighHsTemp): Activates the auxiliary output when the
charge controller’s heat sink temperature rises above the trigger setting for the trigger
delay time. Deactivates the auxiliary output when the heat sink temperature falls below
the clear setting for the clear delay time. This setting can be used to trigger an alarm.
Fault (Fault): Activates the auxiliary output when any error, warning, or fault occurs.
This trigger source is not configurable.
Trigger Source Configurable Ranges
This table contains the available configuration ranges and default settings for
configurable trigger sources. The units vary according to the trigger source selected. If
the selected trigger source is based on a battery voltage, the range also varies according
to the nominal battery voltage of your system.
Note: Changing the trigger level resets the auxiliary output. If an auxiliary output trigger is
active, changing the trigger level will clear the trigger.
Trigger Source Range Default Trigger Default Clear
