Load Detection; Load Detection In Auto Mode; Load Detection In Manual Mode - Deif SGC 410 User Manual

8. Load detection

8.1 Load detection in Auto mode

The controller detects the load (on mains/genset) from the contactor outputs, for example Close genset contactor and Close mains
contactor or Open mains contactor and Open genset contactor. These outputs must be configured in accordance with different types
of Auto operating modes and configuration.
Contactor status inputs are not used for load sensing in any type of Auto mode.
For Mains load sensing, two configurations are mandatory:
1. Mains monitoring must be enabled.
2. The CT location in the panel and the controller configuration must be on the load cable.

8.2 Load detection in Manual mode

The controller uses one of the following methods to detect loads during Manual mode:
• The controller detects the load (on mains/genset) depending on the Generator contactor latched and the Mains contactor latched
inputs (if configured) and their real-time status.
• If the inputs are not configured, the controller detects the load depending on the Close genset contactor and Close mains
contactor or Open mains contactor and Open genset contactor outputs. These outputs are configured with the controller buttons
or contactor controlling inputs, for example Close genset/Open mains or Close mains/Open genset.
In case of MCP Panels, since the genset and mains contactors are not configured, the detected load is treated as load on the
genset only.
