Console
This is the main unit of the SafeGuard™ system. The
console continually scans for a blocked indication. It
consists of a display, power button, and volume buttons.
Sensor
The sensor assembly is a liquid flow chamber sur-
rounded by a blockage detection shroud. The bottom
openings of the sensor assembly accommodate a
variety of plugs (male) and caps (female). The sensors
may be mated with other sensors in a manifold or used
individually. The chamber contains a detection cartridge
which rises with flow. Sensors models are marked with
an imprint in the clear ring at the top of the sensor body;
standard sensors are marked “P2” and sensors de-
signed for use with fumigants are marked “T1”.
Fittings
Micro-Trak offers a wide variety of O-ring seal fittings to
connect SafeGuard™ sensors to your plumbing system.
The use of non-Micro-Trak fittings with SafeGuard is
strongly discouraged and voids the warranty in the
event of damage caused by leakage.
Implement Switch & Module
SafeGuard can accept an optional Implement Switch
and corresponding Module. This option silences the
audible alarm on the SafeGuard when the implement is
not in use. The Module provides the interface between
an implement switch and SafeGuard wiring and can be
placed at any point in the chained sensor connections.

Implement Switch Module
Implement Switch Module with Whisker Switch
A three-pin Metri-Pack connector joins the implement switch. The switch is con-
nected between pins A & C. When the switch is closed the audibel alarm is on.
When the switch is open, the audible alarm is muted and HOLD is displayed. The
display still shows blockage and error indications when HOLD is displayed.
The implement switch module can be installed at any position on the data line. If
is the last item on the data line, a termination cap should be installed on the open
connector.
The Implement Switch has a magnetic base which allows it to be positioned on the
implement as needed.
The coiled spring actuator will active when moved in any direction.

Operation
When the console is turned on it searches for sensors and implement switch mod-
ules installed on the data line. During the power up sequence the console displays
the number of sensors found, for example: S16 indicates 16 sensors were detect-
ed during power up. If the number of detected sensors has changed since the last
power-up sequence, the console will pause, display the new sensor count, and
beep to alert the operator. Operator must acknowledge the new sensor count by
pressing either volume button to continue the power-up sequence.
• Devices are numbered sequentially based on their position on the data line
starting with # 1 being closest to the console end of the cable.
• Sensors and implement switch modules are numbered separately so the first
implement switch module on the data line is always module # 1.
The console continually monitors the sensors for a blocked indication. When a
blockage is detected the console immediately alerts you by flashing the red warn-
ing LED, sounding an audible alarm, and displaying the number of the sensor that
is blocked. This alert will remain until the blockage is cleared. With the implement
switch activated the display should show that all runs are blocked, and HOLD is
displayed (audible alarm muted). This serves as confirmation that the system is
working properly.
Power – Turns the system on or off.
Warning Indicator – This flashes
to indicate a blockage. The audible
alarm will be beeping unless the
volume setting is at minimum.
Volume decrease – Pressing this
decreases alarm volume. The lowest
setting silences the alarm. The alarm
will remain muted until the volume
setting is increased. Cycling power
does not turn the alarm back on!
Volume increase – Pressing this
button increases alarm volume. Power Warning

Up
After every start-up, confirm that the displayed number of detected sensors
matches the actual number of sensors used on the implement. If it does not
match, refer to Troubleshooting section of this manual on p. 8.

Power Up Sequence
• Elapsed Time - Total cumulative time the console
has been turned on.
• Software part number - The part number of the
SafeGuard™ software.
• Software Revision - Revision designator for the
SafeGuard™ software.
• Number of sensors detected - The system counts
the blockage sensors it sees on the data line
on power up. If the number of detected sensors
changes during operation, an ERROR is generated.
This example shows 16 sensors detected.
If the number of detected sensors has changed
since last power-up, the current count of sensors
will be displayed, the audible alarm will sound, and
the warning indicator led will flash.
Operator must acknowledge the new sensor
count by pressing either volume button to contin-
ue the power-up sequence.
• Implement Switch Module Status - The system
indicates if an implement switch module is detect-
ed. The total number of modules detected will be
displayed. This example shows 1 implement switch
module detected.
SafeGuard™ displays a sequence of information screens during the power-up routine.

Normal Operation
System Status – Not Applying Liquid
Typically the SafeGuard is turned on before liquid application begins, so the
sensors detect blockage (no flow) after initial start-up. The system will display ALL
BLOCKED, or ALL BLOCKED HOLD if an implement switch is being used and is
open. If the HOLD indicator is lit the audible alarm is silenced.
System Status – Normal Operation
While applying, the display shows ALL GOOD.
System Status – Blockage Detected
When a blockage is detected the display shows
the number of the sensor which is reading
blocked. If there are multiple sensors blocked,
the display will scroll through all blocked sensor
numbers, i.e. # 7… # 12... # 28. Sensors are
numbered starting at the first sensor on the
data line.
The warning LED flashes red and the alarm
sounds once every three seconds. The audible
alarm is muted if an implement switch is holding
the system in standby mode (HOLD), or if the
volume is set to the minimum setting.

Console won’t turn on
Is there power on the console power cable? Pin A is +12 VDC, Pin B is ground.
• NO Troubleshoot for possible blown fuse, broken wiring or bad connections
on power cable. Verify there’s power at cable connection point.
• YES Disconnect data cable and try to turn on the console. If it turns on with
data cable disconnected troubleshoot damaged cable or sensor assembly. If it
does not turn on with data cable disconnected, replace console.
Sensors Not Detected
Several sensors in a row missing - Check connection between last good sen-
sor and first bad sensor. Bypass first bad sensor in string with extension cable
or adjacent sensor leads.
Single sensors not detected - Isolate or verify bad sensor by bypassing sus-
pect sensor with extension cable or sensor leads. Cycle power on console to
re-scan for sensors.
Implement Switch Not Working
HOLD indication on display won’t go out
Using a jumper wire short pin A to pin C on three-pin implement switch module
connector. If the HOLD indicator goes away, replace implement switch (not
module). If it does not go away, replace implement switch module.
HOLD indication won’t turn on
Disconnect implement switch from module. Does HOLD indication turn on?
• NO Replace implement Switch Module
•YES Verify implement switch operation / replace implement switch.
Sensor not detecting blockage or Showing blockage when not present
Doesn’t read BLOCKED
If the cartridge is at the bottom of the sensor assembly and the sensor does
not indicate BLOCKED, verify cartridge is in sensor tube with tail on top/ball on
bottom. If this is correct, replace sensor.
Doesn’t read GOOD
Remove cartridge from sensor chamber. Sensor should read GOOD. If it
doesn’t read GOOD with cartridge removed, replace sensor.
