Figure 18 – Sentinel, Start Assist Tool
When the red Preheater status light turns off, remove the Start Assist Tool, and slowly release
the plunger while watching the fuel pressure gauge and ensuring that there is no change in
pressure as the plunger is being released.
When the catalytic pad is within the designated temperature range, the catalytic reaction should
hold the safety shut-off valve open enabling a continuous reaction and maintaining the flow of
fuel. If the reaction is interrupted the safety valve will close and disrupt the flow of fuel.
If the safety shut-off valve does not stay open, refer to the Troubleshooting section.
NOTE:
If the plunger is released too soon, the safety shut-off valve will close, and fuel
will not flow to the system.
WARNING!
Start Assist Tool MUST be removed for normal operation after the start-up
sequence.
8.
Once the system is running, check all fuel lines for leaks using a commercial leak detection fluid.
9.
5 minutes after releasing the valve plunger, insert voltmeter leads into the sockets marked [ +
VPU – ] and ensure that the voltage is slowly increasing.
10.
Wait 45 minutes to 1 hour for the Sentinel TEG to achieve operating temperatures.
As the unit powers up, the voltage will climb from zero to the factory set OCV as listed on the
data plate.
WARNING!
When the TEG is operating, surface temperatures of the unit can approach
temperatures close to 200 °C [392°F]. Avoid contact of skin and clothing with the
surfaces of the TEG to avoid burns.
