I also found a few results on the web for "miller and falls generator automatic transfer switch". One of the results is a 240V Automatic Transfer Switch by Millers Falls that can be used with GSD7500 & GSD9000 Series Diesel Generators . This switch can be wired directly to the house or workshop mains power fuse box. In Automatic mode, the switch will automatically start the generator if mains power fails for whatever reason. Once the generator is up to full speed and generating voltage at 50Hz, the switch will feed the power into the required load point. When mains power is restored, the ATS will transfer load from the generator back to mains power then shut down the generator. This same function can also be performed in manual mode if required. The wiring of the ATS must only be performed by a licensed electrician. The solenoid operating mechanism of the ATS ensures a high-speed transfer of loads between alternate sources of power, regardless of current draw. These ATS transfer boxes are available in 3 models to suit Millers Falls GSD7500 & GSD9000 (silenced & open frame) diesel generators, GSD13000 diesel generators (silenced & open frame), GSC12000i-Y & GST11000A petrol generators

For your question, i have replied many people, why generator set can start but not generate electricity?
Here is some reasons for reference:
1.After the diesel generator is stopped, the residual magnetism is often lost, because the material used for the magnetic pole of the exciter is close to the soft steel, and the residual magnetism is small. After the shutdown, when there is no current in the excitation winding, the magnetic field will disappear.
2.The magnetic pole of the diesel generator loses its magnetic properties.
3.Damage of excitation circuit components or circuit breakage, short circuit or grounding phenomena.
4.The exciter brush is not in good contact with the commutator and pressure of brush holder is insufficient.
5.Excitation winding wiring error, opposite polarity.
6.Stator winding and rotor winding of generator set open circuit.
7.Poor contact between diesel generator brush and slip ring, or insufficient brush pressure.
8.Diesel generator lead wire wiring is loose or switch contact is poor.
9.The fuse box is fused.
10.The "auto-manual-de-excitation" switch on the control panel is in the de-excitation position (automatic generator set has "auto-manual-de-excitation" switch).
11.The voltmeter is damaged.
12.Rotary rectifier module is damaged.

Normal starting procedure of Perkins Generator set

1. As far as possible do not start the generator set under load conditions.

2. Transfer the key switch to the starting (STAR) position. The engine should start immediately.

3. After the engine starts, return the key switch to the running (RUN) position. If the engine has not started after 10 seconds, turn the key switch back into operation and (RUN) for 10 seconds. Then repeat steps 2 and 3. If the engine is still unable to start after three attempts, please find out why.

4. After engine starts, follow steps 4.a and 4.b.

A. Check the oil pressure.
B. Check the machine for leaks.
C. Make sure the battery is charged.
D. After running the engine for five minutes, check the generator monitoring system. Make sure the engine works properly before loading.

Note: do not use ether-like spray starting aids in cold weather. Otherwise, it could lead to explosion and personal injury.

The use of water jacket heaters or extra battery capacity improves the machine's start-ability below 10 ?.

Methods for checking and cleaning the core of the rear cooler of Perkins generator set

Check for damage, corrosion, dirt, grease, insect stains, leaves, oil and other debris on the cooler. Clean the cooler if necessary.

is the auto transfer switch rated to handle a 60 kva gen set cus you can use a larger auto switch on a smaller gen set but it don't work the other way cus you'll be burning up wires and contactors and have a fire !
