LOAD MANAGER PROGRAMMING
Recognizing that priorities may change after an installation is made, the Load Manager Mark II is
designed so that the sequence of load removal may be easily altered.
At installation, the highest priority load is wired to relay K1 which is operated by terminal 3. The second
highest priority load is wired to relay K2, which is operated by terminal 4. A total of 8 relays, decreasing
in priority are operated by terminals 5, 6, 7, 8, 9, & 13. See Figure 4 - Schematic, Installation.
Upon start-up, when the Load Manager Mark II operates as a sequential loading device, the loads are
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 Mark II will deenergize loads at approximately 2 second intervals starting
with the lowest priority. Loads will be removed until the voltage sensed returns to normal. The exact
interval between load removals depends on the degree of the overload and the capacity of the
batteries. With only a slight overload and large batteries the time interval is extended.
After installation the user may vary the priority by altering the switch setting from the BASIC SETTINGS
illustrated on Figure 3 - Relay Wiring Connections.
Each switch controls the operation of a relay. The actuation sequence of a particular relay
is controlled by the individual levers of each switch. Lever #5 is the lowest priority, while
lever #1 is the highest. It is thus possible to arrange the relay operating priority for the 5
lowest priority relays.
NOTE
The Load Manager Mark II contains the load switching relays. The
manual switches wired by the installer control the 12 volt supply to these
relays.
THE RELAY CONTACT CAPACITY IS 30 AMPS. DO NOT EXCEED.
Caution: There are 5 switches, each with 5 levers. Only one lever on each switch my be in the
"ON" Position.
