2.1 Set Point Options
>SYSTEM 1 COND SETPOINT<
SET POINT
DIFFERENTIAL
HIGH ALARM
LOW ALARM
LIMIT TIME
Note: Each alarm value can also be set-up to be displayed or not on the front screen as will as remotely
notified or not if connected to the Web Advantage server.
2.2 Make-up or Miscellaneous Conductivity
Tower systems with this option have an additional menu on the review page labeled SAMPLE METHOD. The
sample method pop-up screen allows the user to select continuous or cycles control. With cycles selected
under Settings a best and worst cycles value is attached to a best and worst make-up conductivity value. The
controller will control the cycles proportionally between the two cycles values as the make up conductivity
changes between the two identified values.
>SYSTEM 1 COND SETPOINT<
DIFFERENTIAL
HIGH ALARM
LOW ALARM
LIMIT TIME
Note: If continuous is selected the standard settings are used for system conductivity and the
miscellaneous conductivity (labeled M COND) is the set points menus.
2.3 pH and ORP
The pH and ORP set point settings follow the same format as shown above in section 2.1.
>SYSTEM 1 pH SETPOINT<
SET POINT
DIFFERENTIAL
HIGH ALARM
LOW ALARM
LIMIT TIME
Note: When the Limit Time value is met it will force off the control relay being driven by pH or ORP.
To reset the limit timer and get the control relay active again enter a new Limit Timer value.
SET POINT - What reading turns the relay on
DIFFERENTIAL - Amount reading changes by before
the relay is turned off
HIGH ALARM - What reading generates a High alarm
notification.
LOW ALARM - What reading generates a Low alarm
notification.
LIMIT TIMER - What amount of continuous bleeding
will generate a time alarm notice. The bleed is not
locked-out by this alarm (pH, ORP and mA in functions
are).
BEST MAKEUP - Conductivity of best expected
makeup water.
BEST MAKEUP
BEST CYCLES - Cycles desired with best water.
WORST MAKEUP - Worst expected water.
BEST CYCLES
WORST CYCLES - Cycles with worst water.
WORST MAKEUP
SYSTEM MAX - A fixed conductivity set point that
WORST CYCLES
overides the cycles setpoint if reached.
SYSTEM MAX
INTERRUPT - Only applies to pH settings and
allows the Interruption of pH control during bleed,
INTERRUPT
other chemical feed or both.
SET POINT 2 - Is only present on systems with
SET POINT 2
Dual pH control option. It is a second set point for
applications when an acid and caustic are required.
Set Point 1 will be for feeding acid and Set Point 2 for
feeding caustic.
