7.13 Load Management
The generator set may have been set up at installation to connect and disconnect certain large
loads, such as air conditioners, to manage the total load so as not to overload the generator set.
This requires the installation of relays to the load management signals which allow for the
disconnection of loads. Load management can be set to operate in automatic or manual mode.
Whether in automatic or manual mode, there is a delayed start. Load 1 is enabled three minutes
after the generator set is connected to the house loads, and Load 2 is enabled six minutes after
the generator set is connected to the house loads.
7.13.1 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.
