Rectifier Description	Displays the model number of the installed	Rect 1 Desc	#
{Status Only}	rectifier. NOTE: This information can be	MRF28H54
[MODULES/RECT/INFO]	viewed for each rectifier installed by using the
	horizontal arrow keys.
Rectifier Fail 1-of-N Alarm	The output relay energized if Rectifier Fail 1-of-N	Rect 1ofN Almm+
Security Level {1}	alarm occurs. This is a special rectifier alarm	Minor
[SYSTEM/SET-ALM]	group that signifies that one rectifier has at least
	one alarm condition.
Rectifier Fail 2-of-N Alarm	The output relay energized if Rectifier Fail 2-of-N	Rect 2ofN Almm+
Security Level {1}	alarm occurs This is a special rectifier alarm group	Major
[SYSTEM/SET-ALM]	that signifies that more than one rectifier has at
	least one alarm condition.
Rectifier Fail Safe Voltage	Rectifier default output voltage if communication	Rect Fail Safem+
Security Level {1}	with the control unit fails.	-54.00 V
[MODULES/RECT/PARAM]
Rectifier Fan Fail Alarm	The output relay that is energized or special	Rect FF Alm	m+
Security Level {1}	rectifier alarm group n of N that occurs when a	n of N
[MODULES/RECT/SET-ALM]	rectifier fan has failed.
Rectifier Fan Fail Alarm Status	The status will be “ON” if the rectifier fan has	Rect 1 FF	#
{Status Only}	failed. NOTE: This information can be viewed	OFF
[MODULES/RECT/INFO]	for each rectifier installed by using the
	horizontal arrow keys.
Rectifier Fault Alarm (RFA)	The status will be on if the rectifier output has	Rect 1 RFA	#
Status	failed. NOTE: This information can be viewed	OFF
{Status Only}	for each rectifier installed by using the
[MODULES/RECT/INFO]	horizontal arrow keys.
Rectifier RFA Alarm	The output relay that is energized or special	Rect RFA Alm	m+
Security Level {1}	rectifier alarm group n of N that occurs when a	n of N
[MODULES/RECT/SET-ALM]	rectifier output has failed.
Rectifier Standby Alarm	The output relay that is energized or special	Rect Stdby Almm+
Security Level {1}	rectifier alarm group n of N that occurs when the	n of N
[MODULES/RECT/SET-ALM]	control unit is holding a rectifier in the standby
	mode.
Rectifier Standby Alarm Status	The status will be “ON” if the control unit is holding	Rect 1 Stdby	#
{Status Only}	the rectifier in the standby mode. NOTE: This	OFF
[MODULES/RECT/INFO]	information can be viewed for each rectifier
	installed by using the horizontal arrow keys.
Store Configuration	Setting this parameter to “Enable” will cause the	Store Cfg	m+
Security Level {1}	current rectifier configuration to be stored (the	Disable
[SYSTEM/DIAG]	display toggles back to “Disable” after entry).
System Current	The total system output current (calculated as the	Sys Current	+
{Status Only}	sum of the individual rectifier output currents).	145.8	A
[STATUS]
System High Temperature	The output relay energized if the System	Sys HT Alm	m+
Alarm	Temperature exceeds the system high	Minor
Security Level {1}	temperature threshold.
[SYSTEM/SET-ALM]
System High Temperature	System Temperature is ambient temperature	Sys HT Thr	m+
Threshold	measured inside the controller. An alarm will be	70.0	C
Security Level {1}	reported if temperature is higher than the
[SYSTEM/SET-ALM]	temperature entered.
