Reliable

Rest easy knowing the ES52 will operate normally every time, all the time, in the harshest of conditions. Unrivaled electronic noise immunity ensures even greater reliability than discrete logic designs. Differential speed sensing minimizes interference with twisted-pair while eliminating the need for coaxial cable. Durable solid-state outputs, with unlimited life, will make service calls rare. An auto-reset fuse protects the annunciator outputs and never needs replacement. An internal self-test algorithm verifies the integrity of every component, before and even after the unit leaves the factory. No wonder the ES52 is supported by the longest warranty in the business.

Compatible

If you're acquainted with other major engine controllers, then you already know how to connect an ES52. The unit has all the common features available with other controllers and can replace them easily without rewiring.

Integrated

Tight integration reduces external components: inductive kick-back diodes and reversed polarity are built-in. The ES52 also includes a multifunction timer output which can be configured for one of the following: Glowplug, SmartChoke™, Airgate, or Slow, which eliminates the need for an external timer!

Smart

These smart features can be invaluable:

1. Zero Speed Recrank - no starter engagement until 0 rpm is reached; you'll never worry about damage to the starter mechanism.
2. Loss of Speed Failure - avoids starter or overspeed damage due to a lost signal.
3. Oil Verification - checks the integrity of the oil circuit prior to starting the engine.

For reduced installation time, a friendly setup mode will ease you through all calibrations. A host of extended lamp indications such as "Engine Stall" will save valuable servicing time by providing concise diagnostic information.

Versatile

Magnetic pickups are often too costly or difficult to install. Universal Speed Sensing additionally accepts signals such as belt alternator, flywheel alternator, and generator AC output in 2 selectable frequency ranges. Whether you're faced with a 12 or 24 V system, or with switched-to-gnd or switched-to-bat(+) failure inputs, the ES52 automatically adapts. Further flexibility is offered with options such as remote annunciation, auxiliary failure input/indication, and custom programming for special OEM requirements.
