2.2 Wiring Guidelines 1. WARNING: DO NOT apply external voltage to annunciator outputs (terminals 13 to 18). This will damage the ES52. If this may occur in your application, place a diode in series with each affected annunciator output. 2. DO NOT use wire smaller than 18 AWG. -
Page 9: Terminal Descriptions
The power for the crank output and fuel output is obtained from this terminal. If the 20A fuse is blown the ES52 will not start. Fuel output provides 10Amps maximum. Fuel output closes to +12/24 VDC when start signal is actuated, and opens when either an Engine failure is detected or when stop signal Operating &... -

A diode across Auto and Start/Stop terminals is required on versions of the ES52 with the Cool- Down feature (ES52 EI, FE, and LT variants). See the tech notes section at the end of this manual for further information. The standard ES52 version does not require this. - Page 12 Operating & Installation Manual for the ES52 Engine Controller...

If the engine has been previously running, and more than 5 minutes of rest has elapsed. If DIP switch 6 is set to the off position, the ES52 does not provide oil verification. The ES52 goes immediately into cranking; it will then check for a low oil failure condition after the oil bypass period has elapsed. -

ES52 because the controller remains in run mode and senses that the generator has stopped. This would be indicated by a Flashing Overspeed LED. By leaving the ES52 OFF for 10 seconds before it is returned to the Auto setting the memory will be cleared and it will function as intended. - Page 24 ES52 controller. The step-down transformer acts to reduce the false speed signal on the line to a level that the engine controller will not recognize as the engine running.
- Page 25 4. Connecting ES52 to a Transfer Switch (or remote device) The ES52 remote start contacts carry high current, up to 20A peak during starting (for more info see RSC1 and RSC2 in section 2.3 on page 9). If necessary use an external normally open relay to limit the current to the remote device.

Questions and answers
how to connect the speed sensing wire to generator ?
To connect the speed sensing wire to a DynaGen ES52 generator:
1. Use a step-down transformer with a primary input of 120 or 240 VAC (depending on generator output) and a secondary output of 12 VAC.
2. Connect the primary side of the transformer to the generator output (line to neutral).
3. Connect the two wires from the secondary side of the transformer to the two speed sensing terminals on the ES52 controller using a twisted pair.
4. Ensure the transformer is around 24VA in size.
This setup reduces false speed signals to a level the controller does not recognize as the engine running.
