The SR–2700 allows you to make changes or customize the
windows. There are two methods for entering or changing
items on the interface.
The

Change

button will 1) cause a toggle-function menu to

appear or 2) cause a keyboard to appear.
1) If the item to be changed has only a couple of choices,

touch the

Change

button and toggle through the choic-

es. Directly touch your choices or use the directional
arrows (depending on the window you are viewing) to
select the item intended for change. After the item is
changed touch either the

button or the

in the

upper right corner of the window to exit (use

to exit

when there is no

button).

2) If the item to be changed needs to be entered or has

many choices, press

Change

and a full alphanumeric

keyboard window, with capital letters, numbers and
special characters, will appear. Touch the characters
needed for the change and then touch

Enter

. The format

for the value to be entered will be on the top line.
Touching

Enter

will change the value unless the format

is incorrect. If you touch

Cancel

, you will go back to the

preceding window and the value will not be changed.

NOTE:

Touching the top line of this window gives

access to international characters.

MAIN MENU (Figure 4)

This section introduces the

MAIN MENU

and

Sub-Menu

items, along with the functions available. Select the desired
sub-menu by touching it with the stylus. Other sub-menus
will become available when the selected window appears.
(Appendix A has a listing of the menu tree; Pages 23 and 24
have menu flow charts.)

Readings (Figure 5)

The

READINGS

Window displays an overview of the status

and on times for the sensors showing pressure, pH, ORP
and temperature.
An ‘x’ in the box after Flow 1, 2, or 3 indicates flow; an
empty box indicates no flow. The window’s mid-section
displays the sensor measurement information, which may
be arranged in any order.

When the flow switches are enabled in the programming,

they allow chemical feed while there is flow, but prevent
feed at no flow. Disable the flow switch in the program-
ming to allow chemical feed at no flow.

The Flow Window displays the following:
ITEM: Sensor names.
MEAS: Current measurement reading. The

Overfeed

box

follows this number. An ‘o’ in any box indicates that that
relay is in overfeed (see Page 9) and will not turn ON until
the overfeed timer is cleared.
SET: Sensor set point.
ON TODAY: Total time the MPS has been on since the last
overfeed clearing time.
RLY: The Relay number.

Data (Figure 6)

The

Window displays recorded data (history) from all

sensors. The sensor readings may be viewed on the front
panel of the controller or downloaded into a PC to print
through NotePad or Excel. The data recording time intervals
may be set by the operator. The range is from one second
(minimum) to eighteen hours (maximum). (See the

GENER-

menu/

Data Setup

sub-menu for more information.) In

the absence of power, the SR–2700 retains all recorded
data and program values for up to ten years.
