Step Description Complete/Measured Values Dealer sign-off Customer sign-off
1 Confirm the air filter covers are removed.
2 Power on engine, check for any fault codes.
3 Check customer Input / Output connections, proper operation (direct rack, secondary gas shutoff valve).
4 Diesel-only startup, ensure proper engine/generator function.
5 Check voltage / current for each phase.
6 Check for leaks (cooling, lube, manifold area, exhaust).
7 Operate engine through as much load range as possible.
8 Confirm no excessive exhaust restriction (including catalyst).
9 Pull a Product Status Report.
10 Measure exhaust Diesel Oxidation Catalyst inlet temperature.
11 Check all temperatures.
12 Check all pressures.
13 Confirm E-stop works.
14 Supply gas system checks.
- Clean, dry gas per Application and Installation Guide, LEBW4977, "Gaseous Fuels".
- <10 ppm H2S present in gas (<50 ppm with a stainless steel aftercooler).
- Gas pressure is (12 to 35 psig).
- Meets required gas flow (per web calculator tool).
15 Regulator pressure is set properly (engine loaded and running) per procedure. Refer to Testing and Adjusting, "Fuel Pressure (Gas System)".
16 Check gas system for leaks.
17 Confirm Software Enabled Attachment works, blending enabled.
18 Enable Dynamic Gas Blending mode.
19 Set desired substitution percentage and check for fault codes (pressure within range, gas valves performance, etc.).
20 Inspect supply gas equipment for proper operation while gas is flowing.
21 Operate engine through as much load range as possible.
22 Monitor all pressure and temperatures.
23 Check engine operation during load steps; tune the engine governor accordingly (ECM or direct rack controller).
24 Operate engine paralleled with other DGB equipped engines with DGB enabled.
25 Check engine operation during load steps; tune the genset controller accordingly (EMCP or other controller). Register the Retrofit
Because retrofits to a prime product will change the configuration of the product, updating the configuration in SIMSi and AIMS is important. If the retrofit information is not provided, Caterpillar will not be able to provide important product updates.
When performing a retrofit installation, record the vital information in Table 37. Note: If the procedure is performed by the customer, ask the customer to record the proper information.
