2. PRODUCT DESCRIPTION
2.1. System Overview
The AV88 is a universal analyzer for use with allAV88 enabled AnalogPlus sensors. The enclosure has -DIN
dimensions for easy mounting and is rated NEMA 4X for outdoor use. Ituses a liquid crystal display (LCD) with
a high contrast backlight for best readability and is
powered with 24 volts DC.
The AV88 is quickly configured for a specific sensor
type with a small plug-in personality module adjacent to
the sensor terminalblocks. This module provides
wiring information about specific sensor connections
and provides the appropriate calibration, configuration
and diagnostic menus. When there is no plug-in
personality module configured inside the AV88, the
measure screen will show dashed lines.
The AV88 has two standard 4-20 current loops.
Options include two alarm/control relays and network
communications to a host computer.
Host communication options include, Modbus,
DeviceNet,RS-232 ASCII, Profibus and others.
There are sevenkeys for menu navigation. The MENU key provides options for calibration, configuration,
communications, outputs and relays. The ESC key is used to return to the measure screen.
2.2. Mounting
The AV88 can be mounted on a wallor panel mounted in -DIN or -DIN forms. A gasket is built into the
display for a NEMA 4Xseal. Mounting instructions must be followed to maintain seals. The AV88 can be pipe
mounted and panelmounted with optional mounting hardware.
2.2.1. Conduit Box Wall Mount
The AV88 conduit box is mounted to a wallor plate with #8 or M4 screws through the mounting holes as
shown. There are seven Pg11 and Pg16 knockouts in the conduitbox. Two cord grips are supplied and it is
recommended thatthey be used in the conduit holes onthe bottomside of the box to prevent rain or moisture
from settling at the conduit interface. It is also possible to mount the box using interior breakouts. Four plastic
caps are provided to seal the interior mounting screws. Nema 4X ratings will be maintained only when the #8
mounting screws are used in the holes outside the conduitbox gasket.

wall or plate with #8 or M4 screws
through the mounting holes as
shown.
Seven Pg11/16 Conduitbreakouts
are available for cord grips or conduit
hardware.

2.2.2. -DIN Panel Mount
A -DIN panel mount bezel and gasket can be ordered to fit the AV88 as shown. The AV88 display is
tightened down to the bezel using the four captured screws in the AV88.The bezel is then mounted to a -DIN
square opening with the hardware shown in the figure below.

2.2.3. -DIN Panel Mount
The AV88 Display can be mounted directly to a -DIN panel opening using the captive mounting screws in the
AV88 and the -DIN supports as illustrated in the figure below. A -DIN bezel gasket can be provided to
ensure a NEMA 4Xseal on the panel.

2.3. Power, Relay and Current Loop Wiring
The AV88 Display comes with two terminal blocks. The 10-pin block on the leftis used to hook up two current
loops and two relays (if installed). The 12-pin terminalblock on the rightis used to hook up 24-volt power, host
communications (if installed) and one of many analyticalsensors. There is a sensor personality module for
each sensor type thatis plugged in and fastened downas shown iffigure 2.1A.
Sensor personality modules show which sensor the AV88 is configured for and provide wiring information.

2.4. Personality Module Insertion and Removal
The AV88 can be configured to work with any AnalogPlus sensor parameter by installing the desired
personality module.
Removal
To remove a personality module,disconnectthe sensor cable from the screw terminals, remove the acorn nut
from the center ofthe box and then pull on the push/pull rod as shown in Figure 2.1B. Be sure to keep the
acorn nut in a safe place so that a new module can be properly secured.
Insertion
Hold the personality module by the push/pull rod.
Insert the guidepost through the alignmenthole.
Gently insert the module. Do not force the
connector pins in place.
When the personality module is seated,secure it
by installing the #4-40 Acorn Nut.
The fullfamily of parameter specific personality modules and associated wiring information is shown in Figure

2.5. Sensor Parameter Wiring
The AV88 can be configured to work with any AnalogPlus sensor by installing the appropriate personality
module. Each module clearly shows how to wire the sensor with terminalnumbers, wire colors and sensor
functions.
Currentparameters include: pH,ORP, Contacting Conductivity, Resistivity,Dissolved Oxygen, Dissolved
Ozone, Toroidal Conductivity and Turbidity.

2.6. Host Communications Wiring
The AV88 can be ordered with or without digitalcommunications to a hostcomputer. Labeling for host
communications on screw terminals 3 and 4 indicates the type of communications provided.
When no host communications option is
installed the label will show “NC” by each
terminal.
2.7. Measure Screen Overview
The AV88 user interface is shown in Figure 2.2. It consists of an LCD module that contains two lines of16
alphanumeric characters and seven keys to navigate the menu. The contrast ofthe LCD module can be
adjusted by simultaneously pressing the escape and up-arrow keys (for more contrast) or the escape and
down-arrow keys (for less contrast).
A pressedkey is identified by a gray background, e.g., .

When a sensor module of the same type is replaced inthe AV88, currentoutput, PID and relay settings are
maintained. If a sensor module ofa new type is installed, these settings are automatically set to default
conditions appropriate to the new parameter.
The measurescreen is the same for all parameters. Itdisplays the sensor value on the top line and the
temperature on the bottomline.The AB indicators on the far right side of the top line indicate the state of the
relays (whenthis option is installed). Anuppercase letter indicates thatthe corresponding relay is energized.
An underscore indicates thatthe corresponding relay is de-energized. The example in Figure 2.3 illustrates the
display of a conductivity measurementat Station Address 1 with relays A and B energized.
When the Sensor Module is absent, the condition will be indicated by dashes on the measure screen as shown
in Figure 2.4.
