Advantage Controls MegaTron - Set Point Options; Conductivity, pH, and ORP Set Points

15
2.1 Set Point Options
SET POINT - What reading turns the relay on
DIFFERENTIAL - Amount reading changes by before
the relay is turned o󰀨
HIGH ALARM - What reading generates a High alarm
notication.
LOW ALARM - What reading generates a Low alarm
notication.
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).
Note: Each alarm value can also be set-up to be displayed or not on the front screen as will as remotely
notied 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 identied values.
BEST MAKEUP - Conductivity of best expected
makeup water.
BEST CYCLES - Cycles desired with best water.
WORST MAKEUP - Worst expected water.
WORST CYCLES - Cycles with worst water.
SYSTEM MAX - A xed conductivity set point that
overides the cycles setpoint if reached.
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.
INTERRUPT - Only applies to pH settings and
allows the Interruption of pH control during bleed,
other chemical feed or both.
SET POINT 2 - Is only present on systems with
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.
Note: When the Limit Time value is met it will force o󰀨 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.
