equal to the value set for the Accumulator Volume, the relay activates for the calculated number of pulses from the
feed monitor, and the accumulated total is reduced by the accumulator volume amount.
If the trigger volume is achieved again before the activation time has expired, the newly calculated feed monitor
pulses per unit volume are added to the remaining number. If the relay state is continuously on for longer than the
Output Time Limit, then relay will deactivate.
Output Details
The details for this type of output include the relay on/off state, HOA mode or Interlock status, total accumulated
on-time, alarms related to this output, current cycle on time, remaining feed volume, accumulator total, cycles of
concentration, relay type and the current control mode setting.
Settings

Target
Enter the desired PPM set point for the product.
Specific Gravity
Enter the specific gravity of the product to be added.
Accumulator Volume
Enter the volume of water passing through the water meter to trigger the chemical feed.
Flow Input
Select the flow meter to be used as an input for this control relay.
Flow Input 2
Select the second flow meter, if any, to be used as an input for this control relay.
Cycles Input
Select the virtual input that is programmed as a Ratio calculation of the system
conductivity/makeup conductivity, or select None.
Low Cycles Limit
Enter the lower limit for cycles of concentration, if used. The calculated on-time is limited
to a maximum value if the cycles of concentration gets too low.
Daily Max Time
Enter the maximum amount of accumulated on-time, in Hand or Auto modes, that the
relay can have between midnight and midnight the next day. If the time is exceeded, the
relay will deactivate, and a Daily Max Timeout alarm will be triggered. The alarm will
clear, and relay allowed to reactivate at midnight the next day.
If the relay was in Hand mode when the alarm was triggered, it will revert to whichever
HOA state it was in prior to being set to Hand.
To override the Daily Max Limit for the rest of the day, press Reset Output
Timeout.

Relay, Counter Timer Control Mode
ONLY AVAILABLE IF HVAC MODES ARE DISABLED IN CONFIG MENU – GLOBAL SETTINGS
The Counter Timer algorithm activates the relay for a programmable amount of time, triggered by the accumula-
tion of a programmable number of contact closures from a Digital Counter type input.
Output Details
The details for this type of output include the relay on/off state, HOA mode or Interlock status, time on, remain
-
ing on-time, accumulator total, total relay activation time, alarms related to this output, relay type and the current
control mode setting.
Settings
Touch the Edit icon to view or change the settings related to the relay.
Feed Duration
Enter the amount of time for the relay to activate for once the accumulated setpoint
number of contact closures has been reached.
Accumulated Setpoint
Enter the number of contact closures required to trigger the relay activation.
Input
Select the input to be used to control this output.
