****** Page 2 ****** INTRODUCTION The 091-79-XX, Load Manager 2, is a device which continuously monitors the voltage of the battery. The unit is field adjustable to other voltages from factory settings. Two output relays are provided. The output relays are capable of switching 30 amperes and both “normally open” and “normally closed” contacts are provided. INSTALLATION AND ADJUSTMENT l. INSTALLATION OF THE LOAD MANAGER 2 Connect the Load Manager 2 to the battery and the loads as illustrated in figure 1. This is a typical circuit; many other variations are possible. It is important to connect the Bat+ and Bat- terminals to that point at which the voltage is to be sensed. II.

****** Page 3 ****** Ill. ADJUSTING OF THE LOAD MANAGER 2 The factory adjustment for the Load Manager 2 is for the first relay to be energized. The 2nd relay is energized at a voltage .5 volts lower than relay 1. No separate adjustment is provided for relay 2. To readjust the setpoint, remove the 4 screws and lift offthe cover. Connect a variable voltage source to the battery input terminals and an ohmeter across the normally open contacts of relay 1. Vary the input voltage to the point at which relay 1 just becomes energized. Turn the trimmer resistor RI 00 slightly CCW to lower the setpoint or slightly CW to raise the setpoint. Check the new setting to determine what voltage will cause the relay to be energized. W. FIGURE 2, VOLTAGE ADJUSTMENT 12.0 VOLTS O VOLTAGE TRIMMER RIOO CAUTION The circuit responds very slowly so allow ample time, 15 to 30 seconds for the circuit to respond to voltage changes. This time delay is required to prevent the relay from chattering for small changes in voltage around the setpoint. 170 Cherry Avenue West Sayville, NY 11796 kussmaul.com KUSSMAUL ELECTRONICS ENERGIZED AND READY WHEN SECONDS COUNT Ph: 800-346-0857 Fax: 631-567-5826 sales@kussmaul.com 4
