Use and Care Manual

1-2014 3. Operation
3.8.1 Automatic Load Management
When set to automatic mode, the user takes no action and can only view which loads are
connected. Three minutes after the generator starts, the load that is connected to genset load
L1 is connected. After a delay of three more minutes, the load that is connected to genset load
L2 is connected. If the connection of loads L1 and L2 exceeds 95% of the generator's load
capacity, they are disconnected by the generator. Following another three minute delay, the
control reconnects both loads following the same connection sequence used in the first attempt
(three minutes apart). If generator load capacity is exceeded again, both loads are disconnected
and no further reconnection is tried.
To select automatic load management and view whether the selected loads are connected while
the generator set is running:
1. Press the LOAD button on the home screen.
2. Press the up or down arrow button to select Automatic.
3. Note which loads are connected or disconnected.
4. Press the BACK button to return to the home screen.
Adjust percent load to match the de-rate.
3.8.2 Manual Load Management
CAUTION
To reduce unnecessary loss of service, it is highly recommended that manual load
management be undertaken only by an authorized Cummins Power Generation dealer.
When set to manual mode, the user is able to view, connect, and disconnect loads. If the
connection of loads L1 and L2 exceeds generator capacity, the AC circuit breaker trips.
To select manual load management when the generator is running:
1. Press the LOAD button on the home screen.
2. Press the up or down arrow button to select Manual.
3. Note which loads are connected or disconnected.
4. Press the double-down arrow button to go the load connect/disconnect screen.
5. Connect or disconnect Load 1 or Load 2 as necessary by pressing either button under
Load 1 or Load 2.
6. Press the BACK button to save the setting and return to the home screen.
