Important Information
•The Senzit Monitoring Device connects to the pressure ports on the downstream side of heavy-duty equipment engine air systems that will be monitored
and requires basic connection of pressure tubes and electrical cable connectors. Refer to this guide for correct installation and connection procedures.
Incorrect installation or connections may result in injury or equipment damage and may void warranty.
•Ensure mounting location is sufficient distance from high heat sources. Senzit Monitoring Device can become damaged if exposed to excessive heat. Avoid
mounting device with ambient pressure sensor facing upwards to safeguard against water accumulation.
•Device operating temperatures are -13° to 176°F (-25° to 80°C)
•Product input voltage: 6V ~ 32V
•Senzit hardware comes with a standard 1-year i2m warranty.
Before Installing Device
•Download Senzit-HD App from App Store or Google Play Store. Tap “Add Device” and scan QR code on the device or device packaging. Then follow the

Installation Instructions
1. Turn off engine. Disconnect negative battery cable.
2. Locate a flat surface for mounting Senzit Monitoring Device near air filter housing. (NOTE: Senzit is designed to withstand outdoor conditions. For best performance, it
should be mounted outside any metal enclosures, with a clear line of sight to the sky. External antenna is available for purchase in cases where Senzit can’t be mounted
outside.)
a. Select a location away from moving parts and direct heat sources.
b. Place device on flat mounting surface and mark the bracket holes.
c. Drill holes in surface (make sure proper clearance around and behind surface).
d. Use self-tapping screws or loose hardware to mount the device and bracket.
3. Install airline tubing and adapters.
a. Insert 6 mm Air Line Tubing into air system pressure port on
Senzit Monitoring Device.
b. Locate air housing service port. Remove cover or existing
indicator from air housing/duct service port. Inspect for
damage or blockage. Install M10 Male Straight or Elbow Hose
Quick Connector. If existing OE monitor has a power wire,
keep it installed by adding the Senzit Monitoring Device in
parallel using the M10 Tee adapter with the OE monitor.
(NOTE: Use M10 Male –1/8” Female adapter if port is 1/8”
thread.)
c. Install 6 mm Air Line Tubing from Senzit Monitoring Device to
air system service port, trimming of any excess tubing using a
plastic tubing cutter.
d. Use cable ties to secure Air Line Tubing away from moving
parts or direct heat sources.

4. Connect Senzit Monitoring Device power cables.
a. Senzit power cable must be wired to fused power supply.
b. To avoid any short circuits, make sure engine is off and negative battery cable is disconnected before connecting Senzit Monitoring Device to
power source.
c. Connect Senzit red power cable (BATT_V) to 12 or 24 volt continuous power source using fuse tap or splice into an existing power cable using
in-line fuse. Connect Senzit yellow power cable (IGN_IN) to 12 or 24 volt ignition power source using fuse tap or splice into an existing power
cable using in-line fuse.
i. Check fuse panel for open circuits, wire in as close to fuse panel as possible. Test light may be required.
ii. Ensure a solid connection is made. Use heat shrink to cover any exposed wires.
iii. Do not wire to oxygen sensors.
d. Connect black ground cable to a grounded source.
i. Ground should be unpainted metal or common ground to ensure solid connection.
ii. Improper ground will result in poor device performance or other issues.
e. Secure all connections away from moving parts and heat sources using cable ties. Additional cable ties may be required.
f. Reconnect negative battery cable to the battery.
g. Turn the ignition key to start equipment or move to accessory position to power device.
After Installation
1. Once plugged in to power, the LED indicator lights will illuminate. The green and blue LED indicators should be on if the device has power and cellular
connectivity. Connectivity can take 5-10 minutes.
2. The power and cellular connectivity status can be determined by the LED Indicator Lights:
a. HD Device:
i. Solid Green with Solid Blue LED –Power and cellular connectivity
ii. Solid Green with No Blue LED –Power but no cellular connectivity
iii. Solid Green with Flashing Blue LED –Power but searching for cellular connectivity
1. (Most applications take 5-10 minutes)
iv. No LED Lights –No power and no cellular connectivity
CAN bus connection
CAN bus connections are not enabled at this time. Wires should be bound and located away from any moving parts.

Troubleshooting
PROBLEM
WHAT TO DO
1. No power
A) Check to ensure wire connections to power and ground are secure.
B) Check to ensure ground cable is attached to bare metal surface.
C) Check to ensure there is no short in the cables.
D) Check to ensure the voltage is within the 12-24V range.
E) Check battery connections.
F) Ensure the equipment ignition has been actuated or key is turned to accessory position.
2. No cellular connection
A) Mount the device outside any metal enclosures.
B) If device cannot be located outside metal enclosure, attach cellular antenna extension, placing the antenna
in a location outside the vehicle. Antenna extension can be purchased through Senzit provider.
3. No data is shown in the app
A) Confirm LED indicator lights are powered on.
B) If both LED indicator lights remain solid, unplug the power cable and let
the system remain without power for 1 hour. Plug the power cable back in,
wait 5-10 minutes and then check the LED Indicator Lights again.
C) Senzit will go through automatic updates the first time it is powered on from the factory. This process can
take several minutes to an hour. It is suggested to allow Senzit to accumulate a few hours before checking for
data.
