Nortec Industries GS Series manual FTBD Hour, Blowdown Rate, Float Check

FTBD Hour

Works in conjunction with FTBD hours.

DATE/TIME/UNITS	FTBD HOURS	XXX

WATER MANAGEMENT	BLOWDOWN RATE		XX%
	FLOAT CHECK		HH:MM	0335
CONTROL TYPE
	FILL CORRCTN		XX%

CALIBRATE	DRAIN COOL:		ON

BLOWDOWN RATE CHANGE VALUE XX% STEAM OUTPUT

Here the user sets the time of day (24 hour format) when they want the FTBD to execute. The time can be set to trigger the cycle during off hours, when the humidity requirements are minimal.

The time is adjusted in one-hour increments.

Blowdown Rate

This parameter adjusts the frequency of blowdown cycles.

DATE/TIME/UNITS	FTBD HOURS	XXX
LANGUAGE CONTROLS	FTBD HOUR		XX
WATER MANAGEMENT	BLOWDOWN RATE		XX%
	FLOAT CHECK		HH:MM	0335
CONTROL TYPE	FILL CORRCTN		XX%
CAPACITY LIMIT
	DRAIN CORRCTN		XX%
CALIBRATE	DRAIN COOL:		ON

FLOAT CHECK CHANGE VALUE HH:MM

Depending on water quality, the blowdown rate can be adjusted from 5% to 50%. The percentage is based on the steam production rate i.e. a 10% BD rate will drain 10 kg. of water for every 100 kg. of steam produced.

The higher the mineral content of the water the higher the BD rate should be set.

Float Check

This parameter sets the time of day the controller will force a float check.

Float checks are important to ensure the water level detection system is operating correctly. The float check also tests the fill and drain system and will report any problems detected.

To set the time of day, highlight the selection then enter the user code (0335). Press enter. Use the UP/DOWN arrows to adjust the hours (24 hour format). Pressing enter saves the setting and indexes the display to minutes. Use the UP/DOWN arrows to adjust the minutes. Pressing enter saves the setting and returns the user to the previous menu.
