2.1 Set Point Options
SET POINT - What reading turns the relay on.
DIFFERENTIAL - Amount reading changes by before
HIGH ALARM - What reading generates a High alarm.
LOW ALARM - What reading generates a Low alarm.
LIMIT TIME - What amount of continuous bleeding will
generate a time alarm notice. The bleed is not locked-
out by this alarm.
Note: Each alarm value can also be set up to be displayed or not on the front screen, as well as remotely
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
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. Boiler Conductivity
the conductivity sampling method.
Timed sampling incorporates a sample timer which allows the boiler to be sampled at periodic intervals.
Sample intervals are adjustable from 1 minute to 99 hours, 59 min. Sample duration (on-time) is adjustable
from 1 second to 99 minutes, 59 seconds.
Sample and hold uses a sample timer for periodic sampling intervals. The unit will sample for its duration
and then hold the blowdown valve closed for a settable period (hold time). The conductivity is checked at the
end of the hold period, if additional blowdown is required the blowdown valve is held open for a preset amount
of time (blowdown time). Then sample cycle is repeated.
Pulse Sample
water instead of the sample interval timer.
Continuous sample has a sample of boiler or condensate water go past the probe continuously. If the
