Emerson MPR25 Low voltage disconnect LVD, Procedure 15 - Parallel verification, Step, Action

			Installation and start-up procedures 65
Procedure 15 - Parallel verification
Step			Action
1		It is recommended to leave the units functioning for at least 30 minutes
		to reach full stability prior to final adjustment.
2		Turn all the DC breakers to the ON position.
3		Turn all the AC breakers to the ON position.
4		To achieve the system float voltage determined by the battery vendor or
		the power engineer, increase the FLT potentiometer of the lowest current
		rectifier, or reduce the FLT potentiometer of the highest current rectifier
		to bring the system float voltage up or down respectively.
		The system float voltage shall be read from the system’s meter voltage
		reading.
		Verify that the system float voltage level is constant while proceeding
		through the next step.
5		The load share amperage for each rectifier must be equal. Adjust the
		individual float potentiometer as needed to balance the current delivered
		by each rectifier. It is recommended that the current from each rectifier
		be at least 3 amperes (that is, 9 A for three rectifiers) for best operating
		results.

	Note:		Some rectifiers may still indicate an RFA (red RFA led).
			A red RFA indicates a rectifier delivering less than 0.1 A.
			Rotating the float potentiometer (FLT) slightly clockwise
			will make the LED illuminate green.

Low voltage disconnect (LVD)

Testing and adjusting the LVD units (NT6C13FA/FH) (Circuit Pack

NT6C13PB Rel. 03).

To verify the LVA and LVD/LVDR operating levels on line, without disconnecting the load, proceed as indicated in Procedure 16:
