Nortec 132-3091 manual Nhmc Operation, Start-Upself Test

SIGNAL LIGHT STATUS

YELLOW	GREEN
OFF	OFF	Off
OFF	ON	Normal operation
ON	ON	Replace cylinder or normal
		startup operation
ON	OFF	Operation fault

The prerequisites for getting power and water into the steam cylinder are as follows:

-on/off/drain switch must be switched on

-control circuit 8-10 must be made

-modulation humidistat, if present, must be calling

-control circuit 82-83 must be made

-control circuit 84-85 must be made

-cabinet mounted humidistat, if present, must be calling

-door interlock switch must be made (interlock switch can be pulled out to operate unit)

Most water does not contain enough conductivity for full boil on initial start-up. Units will need to concentrate the water over a time period (hours to days). During this process both lights are on.

NHMC OPERATION

START-UP SELF TEST

Observe the LCD display when the on/off/drain switch is first pushed on. The microcomputer pc board will check the system components, display in words what it is doing and provide a message if any faults are found. The start-up self-test sequence will be displayed as follows:

LCD	EXPLANATION/COMMENTS
	(WHAT YOU READ)
CONDAIRMATIC MC	Note the V number. It tells you
	the EPROM version.
NORTEC V2...
CONDAIRMATIC MC	Note the model type. Ensure
	NHMC (model type) compatibility
	with spec label (name plate).
	Can be reconfigured if
	necessary.
SYSTEM TEST	Test begins.
LAMP GREEN	Observe green signal light on
LAMP YELLOW	Observe yellow signal light on
CONTACT RELAY 1	Provides 24 VAC to 61-20 and
	external optional yellow lamp at
	control strip to simulate a fault.
DRAIN VALVE	Observe 24 volt solenoid
	activated on drain valve.
INLET VALVE	Observe 24 volt solenoid
	activated on fill valve.
CONTACTOR	Observe 24 volt coil activated
	on contactor OR fan activated on
	blower pack if present.
CONTACT RELAY 2	Provides 24 VAC to 63-36 and
	external optional red lamp at
	control strip to simulate cylinder
	spent.
CONTACT RELAY 3	Provides 24 VAC to 62-40 and
	external optional green lamp at
	control strip.
INTERNAL TEST	Completion of self test.
LAMP	Observe green and yellow
GREEN-YELLOW	lamps pulse on together as sign
INTERNAL TEST	that all passed.
STEAM OUTPUT	Begins normal operation and
INTERNAL TEST	displays lbs/hr.

NOTE: If cylinder water reaches the full cylinder sensor, the LCD will read “MAXIMAL LEVEL”.
