Parameter Locations, Descriptions, and Default Values

PARAMETER NAME/	DESCRIPTION	DISPLAY SCREENS /
[MENU LOCATION]		DEFAULT SETTINGS
Compensation Low Knee	The temperature compensation low knee	Comp Lknee	m+
Security Level {1}	is the point below which there is no	0.0 C
[BATT/COMP]	additional battery voltage compensation
	for further decreases in temperature.
Compensation Method	One of three parameters that control the	Comp Method m+
Security Level {1}	dc output voltage. Activate “ON” or de-	OFF
[BATT/COMP]	activate “OFF” battery temperature
	compensation.
Compensation Temperature	Temperature compensation coefficient	Comp TC	m+
Coefficient	between low knee and high knee in	- 3.00mV
Security Level {1}	mV/cell/°C. (Compensation equals zero
[BATT/COMP]	at 25°C.)
Control Unit Revision	Hardware revision level of the control	Cntrl Rev	+
{Status Only}	unit. This parameter cannot be changed.	000002
[SYSTEM/SETUP]
Conv HV Alm	The output relay energized if the	Conv HV Alm	m+
	Converter Voltage (nominal -48 Vdc) is	Minor
	above the Converter High Voltage
	threshold.
Conv HV Thr	Converters are an optional device used	Conv HV Thr	m+
	to convert +24 Vdc to –48 Vdc.	-58.00 V
	Converter Voltage is converter bus
	voltage measured by the controller. An
	alarm will be reported if voltage is higher
	than the voltage entered.
Conv LV Alm	The output relay energized if the	Conv LV Alm	m+
	Converter Voltage (nominal -48 Vdc) is	Minor
	below the Converter Low Voltage
	threshold.
Conv LV Thr	Converters are an optional device used	Conv LV Thr	m+
	to convert +24 Vdc to –48 Vdc.	-50.00 V
	Converter Voltage is converter bus
	voltage measured by the controller. An
	alarm will be reported if voltage is lower
	than the voltage entered.
Date	Internal system calendar date. Used as	Date	m+
Security Level {1}	a date stamp in the event log.	DEC 16 1999
