ES52 Autostart Engine Controller
For Diesel and Gas Engines
The ES52 is designed to provide autostart control and protection for all types of diesel and gas engine-driven equipment. The module is epoxy sealed in an ultra-compact package with mounting compatibility to an industry standard footprint. The module is easily configured using on-board DIP switches and potentiometer adjustments.
Epoxy sealed for protection against vibration, shock, and moisture.
Multi-Function Timer Output: Pre-heat, Slow, Airgate, & Choke.
Warm-up Timer Output.
Detects lost speed signal.
Zero speed restart prevents starter pinion wear.
Simple Installation and Servicing
Plug-in Terminals with no wire crimping required.
20A Removable Relays and fuses eliminate slave relays and external fusing.
Works with Mag Pickup, Alternator or Genset Output (300V max).
Field Settings with potentiometers and DIP switches.
Setup mode for quick calibration.
