1 - Where can I find the CRE Config Software and supporting documentation for my CRE TECHNOLOGY product?

• Visit the download area page for the device on our website. All information and PC Software for the devices are listed here.

2 – I don’t know how to connect my CRE TECHNOLOGY device on my PC in order to program it. What do I have to do?

• Visit our download area page to get the product documentation. You can also consult our youtube page for tutorial.
  • CRE TECHNOLOGY Youtube Channel

3 – I have a commissioning to prepare, What should I do first?

• Ensure that you follow correctly and step by step the “WIKI – commissioning” procedure. Contact CRE Technical Support if you have problems after performing the procedure.
  • Check the documents below

4 - I want to update my GENSYS 2.0 firmware, How can I do it?

• Ensure that you follow correctly the ‘’How to update my gensys firmware sd card’’ procedure.

5  - I can’t connect to my UNIGEN with CRE config Software. How can I do it ?

• Ensure that you follow correctly the “Wiki hyperterminal Unigen” procedure. Contact CRE Technical Support if you have issues after performing the procedure.

6- I do not understand the label or the fault number displayed on the screen of my product.

•  The default number of pages alarm / fault may correspond to a predefined function of the product, in this case you can find correspondence in chapter alarm / fault of the product documentation, you can also get more information on label / numbers in two ways:
  • Enter the number in the info page (I) and see the description.
  •  With the PC, in the System menu / transfer GENSYS-PC file / default alarm summary/ you can download the alarm & fault list configured in the product and see label or the desired number.
•  If the number / label do not correspond to a predefined function, it is a customized configuration, in this case it is recommended to contact the person who completed the program, you can also get more information on this label / number using the two search methods indicated above (info page and PC access).

7- How to replace an existing genset controller by a GENSYS system, or how to combine an existing engine controller with a GENSYS system?

All existing devices in the market can be replaced by a GENSYS system or combined with a GENSYS System, the important points to start are:

• In the case the GENSYS system is combined with existing controller (ex: GENSYS use for synchronization only):
  • Make sure the start sequence and engine control sequence is inhibited (activate “external start sequence” in the CRE Config software/configuration/engine )
  • Make sure the speed and AVR control is manage by the GENSYS only (no several control sources are allowed).
  • Make sure any stop command from the existing controller will result a CB tripping on the GENSYS (ex: fault or remote stop), this is to avoid an unexpected stop during paralleling operation.
• In case the GENSYS replace completely the existing system (ex: refit of engine control unit):
  • Make sure the wiring harness is identify and each potential is known (ex: connection on digital input has to be 0VDC, AC voltage measurement is limited between 0 and 500VAC, Currents inputs are 0-5A, digital output are transistor output 300mA max,…)

It is important to verify each point.

• Make sure the basic main protections will be activate in the GENSYS (Oil Pressure, Over speed, reverse power)
• If the engine is an electronic engine, make sure its configuration allow external CAN J1939 control, or analog/pulses speed control, otherwise contact engine manufacturer for conformity information.

8 – How I can test the engine stability and GENSYS PID?

In order to test the engine stability (ex: because hunting on load impacts, or unstable with low load,…) the test is simple: once the Genset is on load and single, simulate the stability problem (load impact, actuator manipulation,..;) and switch the CRE system in MANUAL mode and, if the engine recover its stability, it means the PID of the CRE system has to be improved; if the instability is present during MANUAL mode operation, it means the engine setting itself has to be improved.

Note: In MANUAL mode, island operation the CRE system has no automatic control on the governors/ecu.
