5.5 Feed
Menu
The Feed Menu adapts to the selected Feed output mode.
Hint: For easiest programming, program Feed Mode first, then step through the rest of the feed
parameters. The modes are defined as follows:
A
Bleed and Feed with Optional
Lockout
Bleed and Feed Mode turns the Feed output On and Off at the same time as the Bleed output.
The lockout setting determines the maximum allowable time for the Feed output. If this time is
exceeded the Feed output is turned off and Locked out until the Bleed output turns off.
B
Feed % of Bleed
Feed % of Bleed Mode tracks the length of time that the Bleed output is on. When the bleed
turns off the feed output is energized for a user defined proportion of the bleed time.
C
Feed % of Time
Feed % of Time Mode turns on the Feed output for a user definable % of a timed cycle. The
time cycle length is adjustable from 10 to 60 minutes.
D
Feed based on Water Contactor
Input
Feed based on Water Contactor Input Mode turns on the Feed output for a user definable time
each time a water contactor pulse is detected. This contactor input can be divided to
accommodate a large variety of water meters. Contacts will accumulate feed time so that all
contacts are accounted for.
E
Feed based on Paddlewheel Input
Mode
Turns on the Feed output for a user definable time each time a defined volume of flow is
detected. This paddlewheel input has a programmable K Factor to work with a large variety of
Hall Effect (square wave, not sine wave) flow meters.
The Feed menu will be indicated on the display by one of the following: (The 'A' indicates that the
feed is being controlled automatically.)
Feed A
OFF
Indicates that the Feed output is currently OFF.
Feed A
10:00
Indicates the length of time that the Feed output has been ON or the length of time that the
Feed output will be ON.
Feed A
NO FLOW
Indicates that Feed control has been suspended because there is presently no flow past the flow
switch.
Feed A
TIMEOUT
Indicates that the feed lockout timer in the Bleed and Feed mode has expired.
Feed A
LOCKOUT
Indicates that the output is currently locked out due to a biocide add or biocide lockout.
Bleed and Feed
Mode
Lockout
Set this for the Feed Lockout Time. The lockout time is the maximum length of time that the feed output
can be on. If the lockout time is set to 0:00, the lockout timer is no longer used and the feed output will be
on for as long as the bleed is on.
Feed % of Bleed
Mode
% of Bleed
This is the % value that is multiplied times the accumulated bleed time to determine how long the feed will
be. For example, if the bleed was on for 10 minutes and this setting was 50%, the feed output would be on
for 5 minutes.
Max Time
This is similar to the lockout time above in that the feed output will not exceed this maximum length.
Feed % of Time
Mode
% of Time
This is the % value that is multiplied times the cycle length to determine the length of time that the feed
output is ON. If the cycle length were 10 minutes and this setting was 40%, the feed output would be on for
4 minutes, then off for 6 minutes and then repeat the cycle.
Cycle Time
This determines the length of the cycle to be used.
