Text Box: ECU®-9988N TERMINAL OUT Text Box: PHYSICAL DIMENSIONS Text Box: SPECIFICATIONS: VOLTAGE RANGE - 9 TO 28 VOLTS MAGNETIC PICKUP - 250-8500 HERTZ STARTER AND FUEL OUTPUT - 5 AMPS MAX LAMP OUTPUTS (TOTAL) - 1 AMP MAX Text Box: The above illustrates the ECU-9988N engine control with an energized to run engine. Placing the control switch in MANUAL or closure of the Remote Start Contacts while in AUTO initiates the Crank mode. The Fuel and Starter Relays are energized causing the engine to begin cranking. If the engine does not start in the allotted time, as determined by the Crank Cycle Adjust and Dip Switch setting, the Overcrank Fault occurs, and the Fuel and Starter Relays are turned off. If during cranking the internal speed switch detects a speed equal to or above the Crank Disconnect Adjustment Setting the Starter Relay turns off, the LOP/HWT delay timer is initiated. After this delay period if the LOP or HWT switch closes the engine will shutdown immediately. If the internal speed switch detects a speed equal to or above the Overspeed Adjustment Setting the engine is shutdown immediately. To stop the engine or to clear a fault condition place the control switch in the Off position. If the signal from the magnetic pickup is lost during cranking or running the engine will shut down and the Overcrank & Overspeed LED's will both turn on.
