****** Page 2 ****** INTRODUCTION: The 091-96-xx LOAD MANAGER 1 H is a device, which continuously monitors the voltage of the battery. The unit is factory set to actuate at 1 2 volts, for 1 2 volt models or 24 volts for 24-volt models, but may be adjusted to other voltages. The output relay is capable of switching 30 amperes, and both a “normally open” and normally closed” contact are provided. INSTALLATION: Connect the Load Manager 1 H to the battery, the load and the fuse as illustrated in figure 1. This is atypical circuit. Other circuit configurations are possible. It is always necessary to connect the Bat+ and Bat- terminals to that point at which the voltage is to be sensed. ADJUSTMENT: The factory setting for the Load Manager 1 H is 12.0 volts (24 v). Field adjustment of the set point is possible. To do this, remove two screws holding down the cover. Note the position of the voltage adjustment trimmer R6. This is the 12-volt (24 v) setting. To decrease the voltage turn counter clockwise. To increase the voltage turn clockwise. Two indicator LED’s are provided adjacent to the terminal strip. When the green LED is lit, the voltage sensed is normal. When the red LED is lit, the voltage is below the set point. The voltage detector can be tested by gradually lowering the system voltage while simultaneously measuring the voltage applied to the input terminals with a precise voltmeter and noting the voltage at which the red LED turns “ON”. The 091-96-xx Load Manager 1 H contains an adjustable high hysteresis feature. With the normal trip point set to 12.0 volts (24.00 volts), the hysteresis circuit maintains the relay energized until the voltage increases above 13.45 volts. This assures thatthe loads being controlled are not energized until the sensed voltage reaches 13.45 volts (26.9 volts). This limits the ON/OFF cycling of the load. The hysteresis may be adjusted using trimmer RI 5. Turning RI 5 CCW will decrease the hysteresis while turning CW will increase. Unless absolutely necessary it is recommended that the hysteresis remain at the factory setting.
