ere is a 0-4-hour time delay adjustment range (available on each timing circuit). e emergency switch provides up to 15 minutes of operation after the timer shuts down the equipment. Power loads can be managed separately through the two independent timing circuits. e Lind Electronics T2 Shut Down Timer (model SDT12-12-081) prevents over-discharge by shutting o up to single 30amp and 20amp loads at a pre-set time, using two independent timing circuits. A timer potentiometer is preset at one hour but can be changed for a maximum delay of up to two hours. e timer can be disabled by removing a diode on the circuit board to make the Load Manager strictly a voltage-sensitive shuto device. A sense wire at the PC board connector leading to the starter crank circuit keeps the Load Manager from shutting o if battery voltage drops too low during the engine start cycle. Once the engine is started and system voltage rises 0.5 volts above the shuto point, the timer is reset. e circuit-board edge connector for this is provided with the new unit, but don’t forget to take it along when transferring the Load Manager P to a new vehicle. Timer control wiring is done through a connector on the side requiring a lead for power, ground and an input from the starter crank circuit. Kussmaul makes a sealed Load Manager in the line, the Load Manager 1HP, but it doesn’t have a timer. e Load Manager P is not sealed, so a protected mounting loca-tion is highly recommended. If battery voltage drops below its set point at any time during the timing cycle, power will immediately be disconnected. At the end of the timing cycle, power to the load will be disconnected. When it senses that the engine is not running, an internal timer is started. Load Manager P is an engine o, timeout timer, voltage sensing device. RAM MOUNTING SYSTEMS SMART ENERGY SOLUTIONS BATTERY BRAIN Kussmaul Electronics’ Load Manager P is one of over a dozen of their DC power management devices. e devices turn o electrical loads at a pre-set time after the engine shuts down.
