Product Identification
n the AOE, observe the specification label on the top of the
O
enclosure. Verify the voltage indicated.
Choosing a Location for the AOE
1) Environment - This product is suitable for ordinary loca-
tions only. It can be used in either indoor or outdoor envi ronments. Note the temperature limits in the specifications.
) Placement - The hardened communication network used to
2
interconnect the SMUs, Flexars, HMI2s, and AOEs permits the
ends of the network to be extended as much as 4000 feet.
This permits placement of the particular product in the area
best suited. For example, the HMI2 could be mounted in
the main control room, and the AOEs could be mounted
closest to the equipment to be controlled by the outputs
thereby minimizing installation cost.

AOE Mounting (See Figure 1)
1) Location: Select a mounting location in accordance with the
Pre-Installation Considerations.
2) Preparation: Open the AOE cover and locate the four cor ner mounting locations. These mounting points are located
outside of the environmentally protected area of the enclo sure. Use the AOE as a template to mark the locations of
the four corner mounting points.
3) Mounting: Secure the AOE to the wall with 1/4" bolts. Note
head size must be smaller than 1/2" and the bolts must be
at least 1" long to reach through enclosure.
4) Accessory Mounting Brackets: If mounting through the
enclosure is undesirable, external mounting brackets can be
purchased as an accessory. The brackets can be oriented
vertically or horizontally.

1) Permanently Connected Equipment - Disconnecting
devices shall by included in the system installation. In instal-
lations where multiple circuits are used (i.e. independent cir cuits for power input, cycle, count and sound),
individual disconnects are required. The disconnects
shall be within close proximity of the equipment,
accessible to operators, and marked appropriately as the
disconnect for the associated circuit. Assure the disconnect
ratings are appropriately sized for the circuit protected (See
Specifications).
2) Circuit Separation - Two cable entry locations are provid ed to aid in maintaining separation of "hazardous live" (typi cally mains voltages such as 115Vac and 230Vac) and lim ited circuits (typically control voltages less than 30Vrms or
42.4VDC). However, since the SMU's single wiring com partment can not absolutely protect against physical contact
between multiple circuits, it is required that all wiring have an
insulation rating of 300v minimum, and a temperature rating
of 80˚C (176˚F) minimum.
3) Protective Earthing - Each AOE is provided with a
"protective conductor terminal" which shall be terminated
to the local earth ground potential. This terminal shall be
used to eliminate shock hazard in the unlikely event of inter nal insulation breakdown. Select wire size that can carry in
excess of the sum of all circuit's maximum amperage.
4) Power Input - The AOE is designed to accept either 115
VAC or 230 VAC (factory set). Verify the intended voltage
supply is compatible with the voltage configuration indicated
on the electronics and the external nameplate. Connect
power as shown to "L1" and "N" being sure to observe polar ity. The AOE features a specific cord connector entry for
power suitable for a cable with a diameter of .17" through
.47". The cord connector can be removed leaving a .875
through-hole suitable for 1/2" conduit fittings.
5) Communications Link - The AOE features a cord connec-
tor entry for communications suitable for a cable with a
diameter of .17" through .47". The cord connector can be
removed leaving a .875 through-hole suitable for 1/2" con duit fittings. Interconnection of the network is performed by
a 2-conductor shielded cable (such as Belden 9322). All
products are interconnected in a daisy-chain, multi-drop
configuration. Order of connection is not important.
Communication networks such as this operate best when
the interconnection has only two ends. "T"s should be
avoided whenever possible. Observe polarity when making
the communication interconnection (D+ and D-). Attach
cable shield in terminal provided.
6) Sensor Compatibility - When using an HMI2 as the
Operator Interface, SiloPatrol SMUse’s and Flexar guided
wave radar sensors may coexist on a common RS-485 com munication buss with an Auxiliary Output Enclosure (AOE)
and the Auxiliary Output Enclosure will function properly.
When using SiloTrack Server Inventory Management
software, the AOE will only function properly when connect ed on an RS-485 communication buss configured for the
SMU

SiloPatrol protocol. AOE outputs can be assigned to Flexar
guided wave radar sensors that reside on a separate RS-
485 communication bus properly configured for the Flexar
protocol in the SiloTrack network setup screen.
Please consult Bulletin 344J (SiloTrack Server).
7) Output Connections - The AOE features additional access
ports for connection of required outputs. The two-card sys-
tem has eight (8) ports, four on each side of the enclosure.
The four-card system has sixteen (16) ports, eight on each
side of the enclosure. Each port is plugged to exclude dust
and water infiltration. When needed, the plug can be
removed leaving a .875 through-hole suitable for 1/2" con-
duit fittings. The output connection cabling utilized should
be suitable for the environment and electrical requirements
of the loads. The analog outputs are non-isolated and self powered. Observe polarity when making interconnection.
The relay outputs are non-powered (dry) and are SPST.

(See Figure 3, 4, 5 and 6)
1) AOE Address Selection Switch - Each AOE must be given
a unique network address that is determined by the rotary
switch setting within the AOE. The network address will cor respond with the output link established in the operator inter face (HMI2 or SiloTrack
network address, communication will be successful to each
without error indication, however each AOE will have identical
outputs. Note that the selected switch setting is denoted by the
selection pointer, not the screwdriver slot (See Figure 5). Switch
selections "1, 2, 3, 4" are acceptable address selections and
refer to AOE addresses 1-4. Switch selection "8" will force all
relays "off". Switch selection "9" will force all relays "on". Switch
selection "A" will force all analog outputs to "4mA". Switch
selection "B" will force all analog outputs to "20mA".
2) AOE Network Termination Switch - Each AOE has a
network termination switch in close proximity to the RS-485
network terminal block. The two products of the SMU/ Flexar/
HMI2/AOE system positioned at both network ends must
have their termination switches "on". The rest of the devices
on the network must have their termination switches "off".

3) AOE Indicators - Three LEDs depict the status of the AOE.
"Power" (green): When lit, it indicates that the AOE power
supply and firmware is functioning.
"Com Error" (yellow)
: When lit, it indicates that no network
communication is being made with the AOE. This can be
caused by a the absence of any operator interface (HMI2 or
SiloTrackTM) links to the AOE address selected, or the halting of
communication caused by the HMI2 exiting the DSPLY mode.
"Config Error" (red)
: When lit, it indicates that an instruction
being received via the network communication is being sent
to an AOE card location that is "empty" or occupied by a dif ferent output type. A "blink" condition means two instruc
tions are for the same card, one being valid (the correct out put type) and the second being invalid (the incorrect output
type).
4) AOE System Reset Switch - Momentary closure of the
pushbutton switch will "restart" the entire AOE system. All
relay outputs are "shut off" and all analog outputs are forced
to "4mA" until new conditions are received via the network
communication and sent to the respective outputs.
5) AOE Card Positions - The analog and relay cards are uni versal and can be placed in any position within the AOE.
However, the card position numbers are fixed and must be ref erenced when establishing the link between channel number
and output within the operator interface (HMI2 or SiloTrack
M

).
Card position #1 must be in place in order to use Card
position #3. Card position #2 must be in place in order to use
Card position #4.

PROBLEM: AOE's green LED is "off" indicating
operational problem
CAUSE/SOLUTION:
1) This condition is caused by the AOE unable to boot its
internal software.
2) Verify electrical power is connected to the AOE.
3) Verify proper alignment of PCB-to-PCB connectors.
4) Press and release "system reset switch" to restart the AOE.
PROBLEM: AOE's yellow LED is "on" indicating a
communication error
CAUSE/SOLUTION:
1) This error is caused by the AOE's inability to receive any
commands designated for the particular AOE address. The
yellow LED will be "off" when the AOE detects that an
incoming message belongs to it.
2) Verify communication connection has been made to the
AOE from HMI2 or SiloTrack.
3) Verify polarity of the communication connection.
4) Verify electrical power is connected to the HMI2 or SiloTrack.
5) Verify that the HMI2 or SiloTrack has been programmed to
send data to the AOE address.
6) Verify the AOE's address selection switch matches that of
the HMI2 or SiloTrack programmed link.
7) Verify that the HMI2 is in "DSPLY" mode, otherwise no AOE
updates are sent resulting in this error condition after a 3 second timeout.
Figure 6
PROBLEM: AOE red LED is "on" or "blinks" indicating a
configuration error
CAUSE/SOLUTION:
1) This error is caused by the mismatch of incoming data and
the type of output (empty, analog or relay) that is located at
the particular link location.
2) Verify the links assigned from HMI2 or SiloTrack match the
type of cards positioned in AOE. The address convention
if controlled by an HMI2 is AOE # (1, 2, 3, or 4), Card Position
# (1, 2, 3, or 4), and Output # (1-4 for an analog card and 1 8 for a relay card). When using SiloTrack, this convention is
preceded by the network # (1-8).
