Sentinel NH3 Troubleshooting

Sentinel shows no flow and rows are grey

1. Make sure the

MASTER

button on the

HOME

screen displays

MASTER ON

. If not, touch the button to

cycle it.

2. Is Sentinel disabling the rows?

A. Go to the

HARDWARE

page. (see pg. 23) If

USE LIFT SWITCH

box is checked, and a dedicated

lift switch is not installed, the Sentinel is disabling flow on all rows because it thinks the implement is

up. Uncheck the

USE LIFT SWITCH

box. If a dedicated lift switch is installed and plugged into the

Sentinel ECU harness, the switch may need adjusted to correctly show the implement status. If a lift

switch is used that is normally closed, the INVERT LIFT SWITCH box needs to be checked.

3. Are you performing a stationary test? If so, a simulated speed must be entered. (see pg. 23)
4. Is a speed being displayed on the Sentinel

HOME

screen when moving?

A. If not, change the speed source (see pg. 23)

Sentinel NH3 Line Sensor(s) will not address

1. Make sure that the Temperature Interface Module is plugged into the Flowmeter Bus connector on Senti-

nel harness.

2. Make sure Line Sensor 1 is plugged into the Temperature Interface Module like on the Component Lay-

out on Page 9.

3. Make sure all Line Sensors are plugged in correct order.
4. Check the

NH3 Module Diagnostics

screen to confirm all Line Sensors and Temperature Interface mod-

ule are green. Press

READDRESS NH3 SENSORS

to restart all the sensors and readdress them.

Sentinel doesn’t show up on my display

1. Verify that the Sentinel ECU has power - 2 green lights should be illuminated on the ECU.

A. Using a voltage tester, check voltage on the ECU harness as identified on pages 13-17.

2. Check connections:

A. Tractor ISO plug

B. CAN and power connections leading to the ECU harness

All Sentinel NH3 Line Sensors are red on NH3 Module

Diagnostics page.

1. On the top of the NH3 Module diagnostics screen, is the module status green? If yes, move on to step 2.

If no, skip to step 3.

2. Unplug all line sensors except Sensor 1. Push

Readdress NH3 sensors

button and see if first sensor

status turns green. If the sensor status turns green, then continue to plug one sensor at a time, pushing

the

Readdress NH3 sensor

button between each time you plug in a sensor. If you come across a sen-

sor that makes all the sensors turn red, unplug it and skip it on the daisy chain of sensors and see if the

sensor after the bad sensor will turn green. If the next sensor turns green, then call SurePoint for sensor

replacement.

3. If the module status is red, refer to page 16 wiring diagram and test voltages.
