Bleed Time Lim xxxx
Use the arrow keys to change the maximum amount of time that the bleed valve can be
continuously open before the controller shuts the valve and activates a Bleed Time Limit alarm.
Press the Enter key to accept the new value. The Time Limit is intended to prevent the bleed valve
from turning over the whole system if the conductivity input fails in such a way that it will never
close the valve. For example, the conductivity may be stuck at a value above the set point, and
can’t respond to changes in conductivity.
Note that the bleed valve will not open again until someone resets the timer!
It will take some experience to find out what the normal bleed time will be. If the valve cycles
open and closed under worst case loading conditions in 30 minutes, you may want to set the Bleed
Time Limit at 60 minutes.
Hand Time Limit xxxx
Use the arrow keys to change the maximum number of minutes that the Bleed output can be
activated in the Hand mode. Any value between 0 and 1440 is acceptable. A value of 0 means the
output can be left on indefinitely. Press Enter to accept the new value.
Spike StPt (mV) xxxx
This menu only appears if the ORP control mode is Direct ORP sensor with Spike. The Spike Set
Point is a higher than normal ORP set point that is triggered by a time of day setting. Use the
arrow keys to change the ORP value at which the relay will close in order to correct the ORP
during the spike time of day. The time of day that the spike occurs and the amount of time that the
higher ORP value is maintained must be programmed using a computer.
Feed Set Points
% of Bld to Feed xxx (if Feed as % of Bleed)
Use the arrow keys to change the percentage of the bleed time that you want the feed output to be
on. For example, if you are feeding after bleed, and the bleed valve is open for 10 minutes, and the
Feed Time is 50%, then the Feed relay will be activated for 5 minutes.
If you are feeding based on Multiple Sources, this menu will appear once for each makeup water
source.
Time Period xxxx (if Feed as % of time)
Use the arrow keys to change the time period you want to use. The time period effects how often
the inhibitor feed occurs, and in conjunction with the % of period to feed, effects how long the
pump will run. Any value between 1 and 1440 minutes is acceptable. Press Enter to accept the new
value.
% of Per to feed xxx (if Feed as % of time)
Use the arrow keys to change the percentage of the time period that you want the feed pump to
run. Any value between 0.1 and 100% is acceptable. Press Enter to accept the new value.
For example, if you are doing feed based on % time, and the time period is 60 minutes, and the %
of period to feed is 10%, then out of every 60 minutes the feed pump will run for 6 minutes.
If you are feeding based on Multiple Sources, this menu will appear once for each makeup water
source.
