Time/Cont.
(Time per contact.) This determines the length of time that the feed pump should be on for each contact
that is received.
÷ Contacts By
This setting allows a divider to be entered. The divider will count actual contacts from the meter until the
setting is reached before a contact is considered to be received. For example, if the divider is set to 10 and
the Time/Cont is set to 5:00, then the feed output would turn on for 5:00 minutes after 10 contacts were
received.

Mode
Time Limit
This setting puts a limit on the amount of time that can be accumulated by the water meter input. Once this
setting has been reached, all contacts will be ignored until the accumulated feed time expires. By setting
Time Limit = Time/Cont., the accumulation of contacts can be disabled.
Hint: Program this first when initially setting up the Feed and Blowdown additions.
Time/Vol
This setting determines the pump on-time once a given volume of water has passed through the
paddlewheel sensor. The volume required to initiate feed is set below.
Vol to Init.
This setting determines the volume of makeup water that will initiate chemical feed.
K Factor
Enter the number of pulses per unit volume that the paddlewheel sensor sends out. This value is usually
printed on the sensor’s flow cell or in its instructions.

Paddlewheel Mode
Time Limit
This setting puts a limit on the amount of time that can be accumulated by the water meter input. Once this
setting has been reached, all contacts will be ignored until the accumulated feed time expires. By setting
Time Limit = Time/Vol., the accumulation of contacts can be disabled. This is set in minutes and seconds.
The following settings are for all feed modes.
Chem Feed Mode
A / B / C / D / E
This allows the user to select the chemical feed mode as described above.
H O A
This sets the Hand Off Auto for the feed output. This was explained in the Bleed Menu section and
functions similarly. In Off position, the output will not turn ON regardless of the feed mode selected.
