INTRODUCTION
The Load Manager Mark II is a device which:
1. Sequentially energizes and deenergizes relays which are mounted inside the unit at approximately
1/2 second intervals in order to reduce transients in a vehicle’s electrical system.
2. Detects when the vehicle’s electrical load is greater than the output of the alternator. When this
occurs, loads are sequentially deenergized until the alternator output is equal to the load.
The Load Manager Mark II contains the following features:
1. An electrical input which changes the Load Manager Mark II from an automatic load shedding
device to operation only as an automatic load sequencer.
2. An automatic override of the Load Manager Mark II which operates all the relays simultaneously by
connecting one input to ground.
3. An adjustable time delay from 2 to 16 seconds which prevents load shedding until the timeout
occurs. This timer starts when the Load Manager Mark II detects an overload. If the battery voltage
returns to normal before the timeout, the timer is reset and no loads are shed.
4. An indicator panel which includes a Power ON LED indicator and a Load Reduce indicator. This
provides the vehicle's driver with the information that the Load Manager Mark II is in operation and that
the loads are in the process of being shed.
5. Internally mounted relays that eliminate the need to supply separate relays in the vehicle. The loads
are wired to the relay contacts at the top of the unit using standard 1/4" quick disconnect terminals.
Each relay output is rated at 30 amperes maximum at 12 volts.
