4.1.4.2 Adjustments – Required for Automatic Load Control
There are 4 potentiometers on the RTC-100 that allow the user to
program the board with required information about the generator
(see Figure 8). Both the RUNNING watts and the STARTING watts
are required for the RTC-100 active load control to function properly.
It the STARTING watts are not know, then enter the RUNNING watts
as the both the RUNNING and STARTING watts on the potentiom-
eters. The RTC-100 utilizes this information to determine if enough
KW is available to turn on the controlled loads when the generator is
connected to those loads.
