Limit Timer – Set this value to the maximum amount of time for the timer to run
while the bleed function is running. If this time is exceeded the controller will go into
alarm and the timer control output will de-energize.
Alarm – The timer activates based on system alarms for powering sirens, lights or
sending remote signals.
Set-point Control – This timer behaves like a conductivity, pH and ORP relay. The
relay will turn on and off based on a probe input set-point.
Disabled – The timer does not activate.
4.8.1 Timers – Pulse Timer
From this menu configure how the timer will run while in pulse timer mode. This mode uses
the water meter input to cause a counter to accumulate a certain volume of water before
the timer is activated. Once the accumulated volume is reached, the timer is activated for
the programmed Feed Time.
Feed Time – Set this value to the amount of time for the timer to run when the
water meter accumulator count reaches the accumulator set.
Accumulator Set – Set this value to the amount of water that needs to accumulate
prior to a timer feed time. The units will be in gallons or liters depending on what
units are set in the configure menu.
Accumulator Count – This is the current running count of the water meter
accumulator.
4.8.2 Timers – Percent Timer
From this menu configure the timer to operate on a percentage of a fixed cycle time
repeatedly.
Example:
Cycle Time=60minutes.
% Minutes to run=10%
In this example the timer will feed for 10% of 60 minutes, or 6 minutes every 60
minutes.
4.8.3 Timers - 28 day (Biocide Timer)
From this menu configure how often and the duration for the biocide 28-day timer to run.
This controller can also perform a pre-bleed, using a conductivity minimum with a fixed
time, and a bleed-lockout function for each biocide feed program. Each 28 day timer has
four (4) programs (Program A to D) with individually programmable settings as follows:
Days/Weeks – Set the days and weeks for the timer to run.
Start Time – Set the time of day for the timer to begin. If a pre-bleed is
programmed, this is the time that the pre-bleed starts. Setting the value to 00:00
means the start time is ignored.
Feed Time – Set this value to the amount of time for the timer to activate the timer
control relay for each start time.
