Instruction manual

Cycles Set Pt xx.xx (if Bleed based on cycles, 1 source)

Use the arrow keys to change the desired set point cycles of concentration.. Any value between 1

and 50 is acceptable. Press Enter to accept the new value.

Dead Band xxxxx (if Bleed based on system conductivity or 4-20 mA input)

Use the arrow keys to change 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. Press Enter to accept the new value.

Cycle Dead Bnd xx.xx (if Bleed based on cycles, 1 source)

Use the arrow keys to change the cycles of concentration value away from the set point at which

the bleed valve will close. Press Enter to accept the new value.

For example, if your set point is 6.00 cycles, and your dead band is 0.10 cycles, then the bleed

valve will open at 6.01 cycles and close at 5.90 cycles. The purpose of the dead band is to prevent

rapid chattering 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.

Retention Time xx:xx (if Bleed based on cycles, 1, 2 or 3 sources)

Use the arrow keys to change the hours and minutes it takes for one makeup water source to

replace the previous water (under normal loading conditions). The controller will not change set

points immediately upon detecting a new water source. It will use the programmed retention time

to gradually transition from one set point to the other. Press Enter to accept the new value.

S1 Cycle Set P xx.xx (if Bleed based on cycles, 2 or 3 sources)

Use the arrow keys to change 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. Press Enter to accept the new value.

S2 Cycle Set P xx.xx (if Bleed based on cycles, 2 or 3 sources)

Same as above, for the Source 2 makeup water.

S3 Cycle Set P xx.xx (if Bleed based on cycles, 3 sources)

Same as above, for the Source 3 makeup water.

S1 Cycle Dd Bd xx.xx (if Bleed based on cycles, 2 or 3 sources)
