indicate element replacement required due to intelli-
gence.
13. Indicates need for element replacement.
14. Indicates (displayed with 15) that initial characteristic
pressure drop is being displayed.
15. Indicates that current pressure drop is being displayed.
16. Indicates (displayed with 15) that average pressure drop

2.2 Batteries
A. Installation
-
Remove battery compartment cover
and install three AA, 1.5V batteries. Install in proper
orientation as noted in battery case. Re-install cover.
B. Life
- Battery life is typically 15 months
operating the LCD display only with 7 days of
LED illumination thereafter. Red light will flash
and battery icon will show when batteries
require replacement.
C. Memory
- Program settings and cumulative informa-
tion is retained during battery expiration and replace-
ment.
2.3 Programming
1. After batteries are installed, red LED light will glow
briefly; display will flash until unit is programmed.
2. Press and hold Enter button for 3 seconds to begin
programming.
3.
Select maximum elapsed time before element replace-
ment - press Scroll button to advance from 1 to 15
months.
4. Press Enter button to accept choice.
5.
Select unit of measure for pressure - use Scroll button
to choose between KG/CM
2
, PSI, or BAR
6. Press Enter button to accept choice.
7.
Select maximum allowable pressure drop - use Scroll
button to advance from 0.01 to 1.00 KG/CM
2
or BAR; or
0.1 to 15 PSI. Use Shift buttons to change advance rate
(BAR and KG/CM
2
-
tenths or hundredths; PSI - tenths or
ones).
8. Press Enter button to accept choice.
9.
Input element type - use Scroll button to advance
from “A” to “H”. See chart on Page 1 for reference.
10. Press Enter button to accept choice.
11.
Select Initalize or Run modes.
Initialize
Use Initialize on initial start-up or after
replacing elements. To Select Initalize,
press Enter when pressure drop and
run Icons are displayed (Initialize symbol
shows). If Initalize is selected the program will ignore
the first 24 hours of operation to allow the element(s)
to achieve a steady state. After this period, pressure
drop measurements will be averaged over the next 144
hours to determine an initial characteristic pressure
drop. The differential pressure calculation used to
determine the optimum time for element replacement
uses this characteristic drop as the starting point.
After the initialization period, Monitor automatically
switches to the Run mode.
Run
To select Run, press Scroll button so that only
the run icon is displayed. If RUN is selected,
the monitor uses the previous initial charac-
teristic pressure drop as the reference. Use this mode if
the Monitor is re-programmed but the element is not
replaced.
12. Press Enter button to exit program mode and begin
operation.
2.4 Display
1.
Run mode
- in the run mode, Processing
icon flashes; indicating that the Monitor is
processing data.
2.
Readouts
- the display cycles through the following
readouts:
a. Current differential pressure.
b. Average differential pressure
over the past 24 hours.
c. Projected days until element replacement. When the
Monitor estimates that filter element replacement will
occur within 60 days, the days remaining will be
displayed. This allows time to have replacement
element(s) on hand.
3.
Alarms
a. Indication of need for element replacement.
If any criteria for element replacement is met,
the red LED will flash.
1) Need for replacement based on
expiration of maximum time -
“0 days” displayed
2) Need for replacement based
on maximum pressure drop -
inputted maximum pressure
drop displayed.
3) Need for element replacement
based on intelligence (calculated
optimum time).
b. Need for battery replacement -
Battery Icon and red LED will flash.
