Liquid Blockage Monitor for ISOBUS

3
System
The SafeGuard™ ISOmod uses an existing virtual terminal
(VT) in the cab to display liquid blockage information
and control settings. On-screen messages and simple
icon buttons on the virtual terminal access all monitoring
functions. View real-time status of individual and total
sensors arranged into dual networks and independent left
and right sensor banks. Data communication is based on
ISOBUS - ISO 11783 standards.
ISOmod™ Interface
This is the information processing unit of the SafeGuard™
ISOmod™ system - continuously scanning rows for
blockages and displaying information on the Virtual
Terminal screen. It provides the physical interface
between the liquid blockage sensors and the Virtual
Terminal. The wiring harness of the ISOmod connects to
the sensors and an available ISOBUS connection.
Sensor & Cartridges
The sensor assembly is a liquid flow chamber surrounded
by a blockage detection shroud. Its physical character-
istics are similar to visual flow monitor devices. The flow
openings accommodate plug (male) and cap (female)
fittings. (See page 21) The sensors may be mated with
other sensor assemblies or used individually. The chamber
contains a detection cartridge which rises with flow. A
fumigant-ready version of the sensor is also available.
Cartridges are available in a variety of weights to
accommodate a wide variety of liquid densities, and also
to provide partial blockage monitoring.
Implement Switch (optional)
The ISOmod wiring harness also has a Run/Hold con-
nection for an optional Implement Switch. This circuit
silences the audible alarm and also enables the review
of recorded screen information. (See page 11)
Micro-Trak makes an Implement Switch (P/N 18541)
with an integral magnetic mount designed to easily
connect to the ISOmod wiring harness.

System Layout
This diagram shows an example of a typical layout. Your installation layout and
plumbing will vary depending on your system requirements. Arrows indicate flow.
(Note: Sensors do not need to be arranged symmetrically.)

Sensor Configuration & Numbering
The SafeGuard ISOmod system has 2 separate networks - labeled Net 1 & 2 on the
harness; each has a separate left and right side. Dual networks simplify monitoring
when applying 2 different products at the same time. On-screen configuration infor-
mation references any network and side (L/R) that is connected at start-up. Network
names can be edited from the Configuration Screen once the system is running on the VT.
Choose a location for the ISOmod enclosure near the center of the implement to
minimize the need for additional extension cables.
Note: From the ISOmod harness, Network Left connections have “Shroud” connectors
and Network Right connections have “Tower” connectors.

ISOmod Installation
1. Place the ISOmod™ enclosure in selected location, mark holes, drill, and secure
with 1/4” fasteners (not included). Mounting holes are 4” apart on center. (See
below)
2. Connect ISOmod™ wiring harness to sensors. Sensors are numbered starting
with farthest Left as #1 and continuing sequentially to the Right. The open
connectors on the last sensors on all network branches must have a termination
cap (included).

Sensor Installation & Location
Paired
Sensors are paired between rows.
1. Mount the sensors vertically with the outlet at the top. See sensor measurements
on page 19 for hole spacing. Sensors must be mounted plumb for correct
operation.
2. Sensor leads are daisy-chained together directly or with the use of extension
cables.
3. The last sensor in each grouping will have an unused connector. Termination caps
shipped with the ISOmod kit must be installed on any unused connector.
Sensors Over the RowSensors Paired
Over the Row
Sensors are placed at each row. Cabling connects to an end sensor and sensors are
daisy-chained together. Typically, sensors are plumbed together using fittings with
integral hosebarbs. (Available in 3/4” or 1” size.)

Manifold style installation
Sensors are joined together using u-clips, like standard visual ball monitors. The
sensor with 3” leads would be used to minimize excess cabling between sensors.
Liquid can be fed to sensor groups via cap and plug fittings, or a Tee fitting designed
to link two sensors with a flow inlet.

Implement Switch
The implement switch mutes the audible alarm - preventing unwanted alarms and
pop-ups on the VT when the implement is not in use. It connects directly to the
ISOmod wiring harness. SafeGuard also responds to Implement Switch signals
available on the ISObus network.
Installation:
1. Remove the supplied jumper from the wiring harness connector labeled Run/
Hold.
2. Connect the implement switch connector labeled SafeGuard Run/Hold to the
wiring harness connector labeled Run/Hold.
The implement switch has a magnetic base which allows it to be easily positioned
on the implement. Simply mount the implement switch near a moving part of an
operating mechanism on your implement (additional extension cables may be
needed).
The switch is wired “Normally Open” and is connected between pins A & C. When the
switch is closed (pressure on tip) the audible alarm is on. When the switch is open
(no pressure on tip) the audible alarm is muted and HOLD is displayed. The display
continues to show blockage and error indications when HOLD is displayed.
Remember: +12 VDC on pin A = Audible alarm ON
Implement Switch Source:
Selects source for implement switch signal.
Local Only - SafeGuard will react to an Implement Switch that is connected
directly to the wiring harness or available signals on the ISObus network.
12345 (example) - SafeGuard will only react to Implement Switch information
originating from a Micro-Trak ISOmod. If that signal is available, a
button with the last 5 digits of the ISOmod serial number will be visible.

Operation
When the system is turned on, SafeGuard ISOmod searches for sensors installed on
the data line. If the number of sensors it finds is different than the last power-up, it will
notify the user with an on-screen message.
Example:
Always confirm the number of detected sensors is correct when the system is pow-
ered-up. If the number of sensors detected differs from the actual number of sensors
installed, troubleshoot the missing sensors. (See page 18)
The system continuously monitors the sensors for blockage. When a blockage is
detected, SafeGuard immediately alerts the operator by flashing the warning triangle
icon, sounding an audible alarm, and displaying the number of the blocked sensor.
This alert will remain until the blockage is acknowledged. With Hold activated by an
implement switch, the display will still show blockages, but audible alarm is muted
and pop-up screen activity is disabled.
NOTE: The open connectors on the last sensors on all network branches must have a
termination cap (included).
ISOBUS Connection
The SafeGuard ISOmod joins to existing ISOBUS compatible connectors to display
liquid blockage information on a Virtual Terminal.
Micro-Trak manufactures “Tap Cables” which allow the SafeGuard ISOmod to connect
without interrupting other devices already in use, and an IBIC breakaway cable to
allow the SafeGuard ISOmod to directly connect to an ISOBUS network.

On Screen Display
The SafeGuard ISOmod is designed to integrate into serial networks that use ISOBUS
standards - ISO 11783. The appearance of the on-screen display will vary depending
on the brand of Virtual Terminal that is used.
The system is also designed to run along side, and in the background, with other
programs on the VT. When a blockage situation happens, the SafeGuard ISOmod
screen will pop-up to the front to allow the user to assess the situation.
NOTE: Blockage monitoring is only active from the Home Screen.
Recording Blockage Information
Problem blockages can be recorded for later review by pressing the “Record Current
Screen” icon during the blockage. The recorded information can later be recalled and
played back when the system is in Hold. (If an Implement Switch is not used, this will
require removing the jumper from the connector on the Run/Hold line.)
Reviewing Recorded Blockage Information
To review information:
1. Place system in HOLD.
2. Press “Play” icon . The top of screen will display “Playback” and recorded
blockage information will be shown.
3. If multiple blockages are recorded, press the arrow icons to navigate
or press “Play” to scroll through automatically. Scrolling can be stopped by
pressing “Pause” .

Section Control
If a Micro-Trak Dual ISOmod is also connected to the ISOBUS network, SafeGuard
sensors can be grouped and assigned to respond to Section Control messages. This
means that as sections are individually controlled on the Dual ISOmod, SafeGuard will
selectively turn off sensors to prevent false alarm readings.
Section Control Setup:
1. Choose MTSI Control as Section Control Source.
2. Choose the channel for setup.
3. Choose the Section Control Source that matches the last 5 digits of the serial
number of the connected Dual ISOmod. Select the intended Channel at right to
associate sections to.
4. Press the Sensor Assign icon at right. (Channel 1 shown.)

15
5. Assign sensors to available sections. Sensors are assigned in ascending numerical
order - refer to page 5 for numbering schemes. In the example shown, Sensor
1 is assigned to Section 1, Sensor 2 is assigned to Section 2, Sensors 3 & 4 are
assigned to Section 3, and so on.
