General non-discriminatory approach
In order to make it easier to read, this document
uses the male form in grammatical structures but
with an implied neutral sense. It is aimed equally at
both men and women. We kindly ask female readers
for their understanding in this simplification of the
text.
Supplementary information
Read the following supplementary information in its
entirety!
The following are highlighted separately in the
document:
Safety Information
Safety information is provided with detailed
descriptions of the hazardous situation. Refer to
Section 4 Safety and Responsibility.
1 Operating Concept
There are two manuals associated with the Aegis II controller, the Assembly and Operating Instruction manual
and a Browser manual. The Browser manual covers all Ethernet and WiFi communications and how to program
the unit via a PC, tablet or Smartphone. Most programming operations are more easily performed in this manner.
1.1 The Front Panel
The AEGIS II uses an OLED (Organic LED) text
display to indicate real time values of up to 6
sensors on the main display, one multicolored
Status LED to indicate alarms and unusual
conditions and 9 multicolored LEDs to indicate
output status.

The communication indication panel is located at the bottom center of the controller face.
A green light indicates the function is available. If the port is in use, the green light blinks.
(Fieldbus is not currently available.)
1.2 Functions of the keys
1.3 Changing the Operating Language
The operating language is currently offered in English only.
1.4 Keypad Lock
The controller has an available keypad lock. If the keypad lock is enabled, access requires a passcode. The
keypad password is the same as the password used in the Ethernet or Wi-Fi browser connection. See 11.2.2
Keypad Passwords.

2 Navigating the [Menu] display
The default display exhibits up to six current sensor values, and STATUS, ALARM and SETPNT buttons. The sensor
choices can be changed or rearranged. See section 2.2 Modifying the ‘Home’ Screen. The STATUS button (F1) is
explained in section 2.1 Input/Output Status. The Alarm button (F2) allows the user to view and clear the latest alarms
for all I/O points. See also section 9.7.1 Analog Alarm Configuration, for more information on alarms.
The SETPNT button (F3) allows the user to edit the set-point of any enabled relay using set-points.

2.1 Input/Output Status [momentary display]
The Home screen, shown here with 6 I/O signal values, has a
momentary display in addition to the three F key choices. The
momentary display shows the status of the input in the same
manner as the status key except that it is only viewed for as
long as you hold down the right arrow.
1- From main display press Down arrow key to invoke a
cursor, then continue with the down arrow to select a
desired sensor
2- Use Right arrow key to momentarily see sensor
information
3- Use Left arrow key to momentarily see any output that is
tied to the selected input
4- Use ESC key to Exit
5- Note: The momentary information will remain on the
display as long as you hold down the arrow key
2.2 Modifying the ‘Home’ Screen
1- To set (modify) the Home Screen press MENU
2- Use Up/Down Arrows to navigate to System then press OK
3- Scroll to Diagnostic then press OK
4- Scroll to ‘Home’ inputs then press F1, adjust
5- Use UP/Down Arrow keys to select what to display on Top, Left OLED Screen
(maximum of six parameters can be displayed on OLED) then press F1 SELECT, you
should see a square box appear in front of your selection.
6- Press F2, NEXT. “Mid, Left” should appear on the screen, use UP/Down Arrow
keys to select what to display in the middle row, left position, then press F1, NEXT, you
should see a square box appear in front of your selection

3 Identcode
All ProMinent products use an identification code (Identcode) product configuration system. The Identcode is an alpha-numeric string of characters, starting with a 4 digit
code describing the basic product type, followed by as many digits as needed to describe all options. The 4 character designation for the Aegis II is AGIb. All Aegis II
configurations begin with AGIb. (The original Aegis identcodes start with AGIa.)

The Aegis II controller inputs are assigned letters
and the outputs are assigned numbers as part of
the programming scheme. This allows, for
example, output relay 3 to be controlled by input
sensor E, Chlorine. The Chlorine sensor must be
input on E and the hypochlorite pump must be
plugged into R3.
4-20mA outputs are the only signals that do not
follow this plan. They are also assigned letters.
