The TEM-EVO is an engine controller supplied by MWM with their gas engines. Other gas engine manufacturers (Caterpillar, Cummins, Jenbacker etc also have dedicated engine controllers.
In the case of the TEM, this is solely and engine management system, the only thing it does with the ac generator is to monitor the stator RTDs.
The TEM relies on a higher level controller to give start and stop commands as well as issuing the generator power demand etc.
The TEM is supplied by MWM in a small Rittal cabinet, complete with cables to connect to the engine wiring. This cabinet is usually mounted near the engine.
The TEM Screen is usually mounted on the front of the generator set control panel. This panel will contain the synchronizer and other control devices. The generator breaker panel which naturally will contain the breaker (usually low voltage), is usually mounted alongside the generator control panel.
Is you arrangement like this?
If so, then what AVAT seem to have done is to design a generator control panel, but without a power breaker panel.
If this is the case, then this AVAT panel is of no use to you, as you will have something that perform the same function.
If you require to remotely control and monitor your MWM sets, then I suggest that you first talk to the supplier / packer of your generating set package, since the generator control panel may have the option for remote control.
Otherwise, you may have to install a new control panel, which may be too complicated.
