INTRODUCTION
The LOAD MANAGER is a device which:
1. Sequentially energizes and deenergizes relays at approximately 1/2 second
intervals in order to reduce transients in a vehicle’s electrical system.
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. When this occurs, loads are sequentially deenergized until the
alternator output is equal to the load.
The LOAD MANAGER features an input which permits selecting the load shedding feature or
operating only as an automatic load sequencer. It is possible to completely override the LOAD
MANAGER and operate all relays simultaneously by connecting one input to the vehicle ground.
An indicator circuit is included to operate a small LED indicator panel. This provides the vehicle’s
driver with the information that the LOAD MANAGER is active and loads are being removed from
the system.

LOAD MANAGEMENT PROGRAMMING
Recognizing that priorities may change after an installation is made, the LOAD MANAGER is
designed so that the sequence of load removal may be easily altered.
designed so that the sequence of load removal may be easily altered.
At installation, the highest priority load is wired to relay 1 which is operated by terminal 3. (NOTE
THAT THE RELAYS ARE NOT PART OF THE “LOAD MANAGER” AND ARE SUPPLIED BY THE
INSTALLER) The second highest priority load is wired to relay 2 which is operated by terminal 4.
A total of 7 relays, decreasing in priority are operated by terminals 5, 6, 7, 8, & 9. See the schematic
of figure 1.

Upon start-up, when the LOAD MANAGER operates as a sequential loading device, the loads are
applied in priority order with the highest priority first.
applied in priority order with the highest priority first.
When the LOAD MANAGER feature is enabled and excessive electrical loads cause a drop in
battery voltage, the LOAD MANAGER will deenergize loads at approximately 60 second intervals
starting with the lowest priority. Loads will be removed until the voltage returns to normal.

After installation the user may vary the priority by altering the switch setting from the BASIC
