Setting Description
Trigger Delay Sets a delay period between when the trigger occurs and when the aux
output is activated.
Clear Level Sets the voltage or temperature level (depending on the selected
trigger source) at which the aux output becomes inactive.
Clear Delay Sets a delay period between when the Clear Level setting occurs and
when the aux output becomes inactive.
For default settings, see "Aux Menu" on page B–6.
Important:
Changing the Trigger Level resets the auxiliary output. If an auxiliary
output trigger is active, changing the trigger level will clear the trigger.
Low Batt Voltage Activates the Auxiliary Output when the battery voltage falls
below the Low Batt Voltage setting for the trigger delay time. The Auxiliary
Output turns off when the battery voltage rises above the Clear setting for the
Clear Delay time. Use this setting if you want the auxiliary output to control a
relay to disconnect loads from a battery that is nearly discharged, or to activate a
low-battery-voltage alarm such as a buzzer or light.
High Batt Voltage Activates the Auxiliary Output when the battery voltage
rises above the Hi Batt Voltage setting for the trigger delay time. The Auxiliary
Output turns off when the battery voltage falls below the Clear setting for the
Clear Delay time. This setting is useful for:
• Installations that have another external charging source such as a wind
generator or hydro generator connected directly to the batteries. The XW
Inverter/Charger Auxiliary Output can control a relay to disconnect the
external charging source from the battery when the battery is in danger of
being overcharged, or control a relay to turn on a diversion load.
• Activating a high-battery-voltage alarm such as a buzzer or light.
• Activating a vent fan to disperse hydrogen from the battery compartment
when the batteries reach their gassing voltage.
Low Batt Temp Activates the Auxiliary Output when the battery temperature
falls below the Low Batt Temp setting for the trigger delay time. The Auxiliary
Output turns off when the battery temperature rises above the Clear setting for the
Clear Delay time. Battery temperature is measured with a battery temperature
sensor. Do not use this setting if a battery temperature sensor 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 Batt Temp Activates the Auxiliary Output when the battery temperature
rises above the Hi Batt Temp setting for the trigger delay time. The Auxiliary
Output turns off when the battery temperature falls below the Clear setting for the
