Control Direction
(only appears if Type of Bleed is Based on System Conductivity or Other 4-20 mA input 4)
Click on the radio button to select between the normal “Force Lower” or “Force Higher”.
Dead Band
(only appears if Type of Bleed is Based on System Conductivity or other 4-20mA input 4)
Type in the text box the conductivity (or ppm) value away from the set point at which the bleed
valve will close. For example, if you are forcing the conductivity lower, your set point is 2000
µS/cm, and your dead band is 100 µS/cm, then the bleed valve will open at 2001 and close at 1900
µS/cm. The purpose of the dead band is to prevent rapid cycling of the relay open and closed,
which can shorten its life. The dead band should be set for the lowest value that still prevents the
relay from chattering.
Bleed On-Time per Makeup Volume
(only appears if Type of Bleed is Time Based on Makeup Volume)
Type in the text box the number of minutes that the bleed valve should be open after a given
volume of makeup water has entered the system. Any value between 1 and 1440 minutes is
acceptable.
Makeup Volume
(only appears if Type of Bleed is either Time or Volume Based on Makeup Volume)
Type in the text box the volume of makeup water that needs to enter the system before triggering
the bleed valve to open. Any value between 1 and 10,000 is acceptable.
Bleed Volume per Makeup Volume
(only appears if Type of Bleed is Volume Based on Makeup Volume)
Type in the text box the volume of water that the bleed valve should let out of the system after a
given volume of makeup water has entered the system. Any value between 1 and 10,000 is
acceptable.
Source 1, 2 or 3 Conductivity Range
(only appears if Type of Bleed is Based on Cycles of Concentration)
Type in the text box the range conductivity (or ppm) values that the controller will use to identify
the makeup water source. For example, if the water from this source is typically 275 µS/cm, set the
range at 200 to 350 µS/cm. Source 1 must be the lowest conductivity range, Source 2 the next
highest, and Source 3 the highest conductivity. The controller automatically enters the
conductivity value of the next range to prevent overlapping ranges, or gaps between the ranges.
Source 1, 2 or 3 Cycles Set Point
(only appears if Type of Bleed is Based on Cycles of Concentration)
Type in the text box the desired set point cycles of concentration if the makeup water source is
Source 1. Repeat for each makeup water source. Any value between 1 and 50 is acceptable.
Source 1, 2 or 3 Cycles Dead Band
(only appears if Type of Bleed is Based on Cycles of Concentration)
Type in the text box the cycles of concentration value away from the set point at which the bleed
valve will close. For example, if your set point is 6.00 cycles, and your dead band is 0.10 cycles,
