BOOK#091-36 INSTRUCTION MANUAL AUTO-TROL Model 091-36 A CONTROL TO PROTECT ALTERNATING CURRENT LOADS FROM LOW FREQUENCY POWER INPUT 3 YEAR WARRANTY KUSSMAUL ELECTRONICS CO., INC. 170 CHERRY AVE., WEST SAYVILLE, N.Y. 11796 TEL: in NY 631-567-0314 TOLL FREE: 800-346-0857 FAX: 631-567-5826 INTRODUCTION: The AUTO-TROL Low Frequency cutout relay is intended to protect A.C. loads by disconnecting them from the power source when the frequency of that power source drops below 60 Hz. This prevents excessive current draw and motor burnouts. The AUTO-TROL is a solid state control operated from the vehicle's +12 volt system. It detects the input A.C. voltage and whenever the frequency of that voltage is below 60 Hz. deenergizes it's power output relay. The AUTO-TROL is wired to the vehicle's battery and is continually energized. It's current drain is negligible and will have no effect on the battery. INSTALLATION: 1.0 Mount the AUTO-TROL in a suitable location and wire as illustrated in figure 1. NOTE: The "neutral" of the A.C. generator must be connected to the vehicle ground and battery "negative". If this does not exist, contact Kussmaul Electronics Co. for special instructions. 2.0 Wire the White/Red wire to the +12 Volts D.C. 3.0 Wire the Black wire to the vehicle ground. 4.0 Wire the A.C. power source to terminal 87 on the relay. Note that this terminal already contains an orange colored wire. The orange wire is the "sense" wire, it must remain on terminal 87 with the power input. 5.0 Wire the load that is being protected to terminal 30. THIS COMPLETES THE INSTALLATION. PLEASE CHECK ALL WIRING TEST: 1.0 Start the engine and operate the generator at it normal speed and frequency (60 Hz). The Green LED indicator on the side of the AUTO-TROL should be lit. The relay is closed and the load energized. 2.0 Set the engine to low idle to produce a generato frequency less than 50 Hz. The Green LED indicator will be "off" and the load disconnected.
