User manual KUSSMAUL 091-75-AT

[. . . ] The system consists of a voltage detector and controller Model 091-139-CONT-12 and a separate 200-ampere rated solenoid, Model 091-139-SOL-12HO for switching the batteries. In addition to maintaining battery isolation the AUTO ISOLATOR I may parallel the batteries on engine starting if the auxiliary battery has sufficient charge to assist in the cranking.

BATTERY VOLTAGE DETECTOR TIMER Figure 1 Block Diagram SYSTEM OPERATION The system receives its power from the ignition switch. With the switch "OFF" all the power is removed from the system and the solenoid is deenergized. As soon as the operator turns the ignition "ON", the system is powered and detects the voltage of the main and auxiliary batteries. If the auxiliary battery voltage is 12. 4 volts or greater, (indicating sufficient charge) cranking the engine will cause the paralleling solenoid to be energized. A 10-second timer will maintain the paralleling solenoid if the engine doesn't start immediately and must be cranked a second time. SOLENOID, Model 091-139-SOL-12HO Volts: 12 volts D. C.
