Parameter Locations, Descriptions, and Default Values

PARAMETER NAME/	DESCRIPTION	DISPLAY SCREENS /
[MENU LOCATION]		DEFAULT SETTINGS
Battery Low Temperature	The output relay energized if the Battery	Batt LT Alm	m+
Alarm	Temperature drops below the battery	Minor
Security Level {1}	Low Temperature threshold.
[BATT/SET-ALM]
Battery Low Temperature	Battery Temperature is temperature	Batt LT Thr	m+
Threshold Security Level {1}	measured at the battery probe. An alarm		0.0 C
[BATT/SET-ALM]	is generated if the battery temperature
	drops below this value.
Battery Low Voltage Alarm	The output relay energized if the dc	Batt LV Alm	m+
Security Level {1}	output voltage drops below the battery	Minor
[BATT/SET-ALM]	low voltage threshold.
Battery Low Voltage Threshold	An alarm is generated if the dc output	Batt LV Thr	m+
Security Level {1}	voltage drops below this value.	22.00 V
[BATT/SET-ALM]
Battery Maximum Recharge	One of three parameters that control the	Batt Max Rechm+
Current	dc output voltage. If Battery Current		50 A
Security Level {1}	surpasses the Maximum Battery
[BATT/PARAM]	Recharge Current, the dc output voltage
	will be reduced (the system limits the
	charging current to this programmable
	value).
Battery Temperature	Battery temperature measured by the	Batt Temp	+
{Status Only}	system controller at the optional battery	25.2 C
[STATUS]	temperature sensor probe.
Circuit Breaker 1 Alias	An alternate name (alias) that can be	Cir Bkr 1	m+
Security Level {1}	assigned to a circuit breaker if desired.		+24V
