Ah, a little more detail, if you are dealing with a specific unit, such as your example 3456, then a serial number would be VERY helpful, as there are three different serial number prefixes for theis family of engines, each with their own little quirks and differences. The AL4 on the EMCPII+ is basically telling you that when it is installed and programmed for use on an electronic engine, the engine ECM is telling the EMCP II+ it has a problem, either an alarm or shutdown depending on how it is programmed (RENR1200, EMCP II+ Manual for EUI Engines, pg 48), so first off, do you have the proper manual for the installed EMCPII+ in conjunction with your engine/generator package?
So you have an indication for low coolant temperature, is that coming from the EMCPII+ or the engine ECM, as it can be programmed in either? Do you have CAT ET? Are you sure the engine ECM has no active or logged codes. Do you have the troubleshooting manual for your engine?
Since both the EMCPII+ and the engine mounted ADEM ECM are broad application controls, there could be a large number of things causing your apparent problems, depends on the flash file installed in the engine ECM, how its adjustable parameters are set, and how the EMCPII+ is programmed.
If you want a start in basic CAT electronics and controls, this may be a good place for you to start, https://www.caterpillaruniversity.com/dlms/PerfCtr, you can sign up and take free on-line classes, most are geared towards earth moving but the basic principles are the same.
If you want more direct help from the forum, provide the serial number of the equipment you're asking about.
