1. Introduction

The AV-9900 High Temperature Short Time Controller provides all USPHS required functions associated with

recording pasteurized product temperature, signaling the flow diversion valve (F.D.V.), and recording the Flow

Diversion Valve position. Additional features allow for multiple diversion set-points, recording active diversion

setpoint, cold product recording - with optional control, and hot water control.

The remainder of this publication will serve as further introduction to the features of the AV-9900, as well outlining

procedures necessary to perform the PMO Appendix I tests.

Document Revision 3.0 4

2. Key Product Features

The AV-9900 Microprocessor Based Safety Thermal Limit Recorder incorporates many time proven features found in

earlier Anderson products. Ease of operation and high safety standards were brought together specifically to meet the

demands of the pasteurization process. Key features of the AV-9900 are as follows:

2.1. Hot Product Temperature Sensor

The Hot Product Sensor is a dual element, 1000 ohm Resistance Temperature Detector (RTD). The Primary RTD

supplies the recording - thermal limit signal input, with the Secondary RTD supplying a verification for that signal.

Sensors are available with a wide variety of sanitary connections featuring a 5-1/2” or 7-1/4” probe length.

Provision for the

Health Authority Seal

on the stainless steel conduit housing provides separate servicing of the probe,

and ease of installation. Overall response characteristics allow for cable runs of up to 500 feet.

Chart ranges are programmable, and are factory set to meet all Pasteurized Milk Ordinance (PMO) requirements. In

addition, criteria of 12 hour rotation and 1OF divisions have been met.

2.2. Diversion Switching

Diversion set-point circuitry provides for up to five selectable cut-in/cut-out temperatures. User configurable

parameters exist for displaying the active set-point. The current set-point is recorded to the chart for verification at

time of cut-

in. Diversion set-point values are easily modifiable upon breaking the Health Authority Seal, and entering the system

program mode. In addition to restricting access to the Run/Program shunt jumper, the chart plate seal also prevents

modifications to circuit boards and input/output wiring connections.

Flow Diversion Valve position is indicated by red and green lights on the chart plate, in addition to being recorded by

an event pen on the outside area of the chart. The event pen position is outward for forward flow on all diversion set-

points. Selection of the current diversion set-point is accomplished via the front mounted user keypad and display.

Five function keys become active, allowing the user to choose the desired set-point.

2.3. Diagnostic Circuitry

The AV-9900 provides fail-safe operation via internal self-diagnostics of the Hot Product Probe input signals. The

Primary RTD input signal is continually referenced against the Secondary RTD signal. The result is indicated on a

series of LED’s, located just above the user display, and labeled

Sensor Balance

. If both RTD elements are in

agreement by less than .5 OF , no LED’s are lit. Each increment of .5OF shift will light an LED. At the point at which

the elements differ greater than 2OF , the AV-9900 will go into automatic divert. In addition, the user display will

indicate that a

Probe Failure

has taken place. Until a replacement Hot Product Probe is installed, the unit will not

allow a forward flow condition to take place.

2.4. Pen Drive Mechanism and Chart Printing

The pen drive mechanism is similar to a dot-matrix print device in that a series of dots are placed down onto the paper

chart. This mechanism is fully alpha-numeric capable, allowing printing of ranges, units, alarm’s, etc. to the chart. All

four pens are housed within a small pen cartridge, in a straight line arrangement. As a result, all data printed to the

chart is on the same time line. No lag exists from pen to pen as with typical felt pen type recorders. Chart ranges and

scales are factory programmed, per applicable PMO requirements, but may easily be re-ranged in the field. Charts are

plain paper, and pre-printed only with circular ring divisions. Division spacing meets PMO requirements. User

defined scales and chart ranges are printed in one of four available colors.

2.5. Cold Product Record - Control

The AV-9900 may be configured to receive an input from an RTD, or mA transmitter, measuring the Cold Product

temperature as it exits the pasteurization loop. This function may be specified at time of order, or upgraded in the field

at a later date. A factory set, field modifiable scale has been programmed for the recording pen. Data will be recorded

in color allowing easy interpretation when reviewing chart information.

An additional option exists for controlling the Cold Product Cooling within the AV-9900. An optional PID Loop

Control function can be specified at time of order, or upgraded at a later date in the field. This function will receive its

input from the same probe measuring the Cold Product temperature. In turn, a desired set-point may be programmed,

with output signals interfacing to the cooling loop. The PID, or control functions, will vary the resulting output signal

based on rising above or falling below the desired Cold Product set-point.

2.6. Hot Water Loop Control

The AV-9900 may be configured to receive an input from an RTD, or mA transmitter, measuring the Hot Water Loop

temperature. This function may be specified at time of order, or upgraded in the field at a later date. In turn, a desired

set-point may be programmed, with output signals interfacing to the Hot Water Loop. The PID, or control functions,

will vary the resulting output signal based on rising above or falling below the desired Hot Water set-point.

If various products are being processed, up to five Hot Water Controllers are available (one for each STLR diversion

set-point). Each controller may have it’s own set-point and PID tuning parameters. When the operator selects a new

STLR diversion set-point, the corresponding Hot Water Controller is automatically selected. Again, Hot Water

Control set-points and PID tuning parameters would have been pre-programmed

3. Hardware Descriptions

In performing the required testing, access will be made to various areas of the AV-9900 hardware. Specifics are

illustrated as follows:

3.1. Chart Plate Seal

Provisions have been provided for placing the Regulatory Wire Seal in the upper right corner of the chart plate. When

in place, this seal prevents unauthorized access to not only the internal wiring, but also access to the Security Mode

Shunt (see next section).

3.2. Security Mode Selection Shunt

The AV-9900 is equipped with a movable shunt to allow toggling between RUN and PROGRAM modes of operation.

While in RUN mode, access is prevented to all system critical parameters (ranges, setpoint changes, etc.). Changes

may be made to display functions as well as selection of the currently active diversion setpoint. While in PROGRAM

mode, full access to all system parameters is allowed.

NOTE:Moving the Security Mode Selection Shunt to the PROGRAM position will

immediately

force the unit to

DIVERT flow. If already in DIVERT flow, the unit will remain in that mode even if the hot product temperature rises

above the active setpoint.

The following diagram illustrates the location of the Security Mode Selection Shunt, in addition to the settings, RUN

or PROGRAM.

Document Revision 3.0 9

4. User Display

Also located on the front chart plate is the User Display. From here, data such as a digital readout of the STLR

temperature value may be viewed. This display will be utilized in selected areas of the Pasteurized Milk Ordinance

Appendix I testing.

Two options exist for the display; CONTINUOUS DISPLAY and SEQUENCE DISPLAY. When in continuous

mode, the selected parameter is viewable at all times on the display. This is the required mode for completion of the

Appendix I testing. While in sequence mode, various parameters scroll over the screen at a timed interval.

If the unit is set to SEQUENCE display mode, the following procedure will allow the unit to be placed in continuous

mode, with the STLR temperature visible:

4.1. Setting CONTINUOUS Display
