Display
Contactors
The display indicates whether the primary (main supply) contactor is open or
closed or whether the contactor is armed and ready for closing. The main supply
open/close indicator is visible at all times.
The icon will indicate three possible states of the contactors.
A secondary contactor is also available to control loads such as night storage
heating. The same behaviour as defined for contactor 1 is also applied to
contactor 2.
Load Control Relay
The LC1 icon represents the state of the load control relay. When LC1 is
illuminated, the load control relay is closed and the load is connected. If LC1 is
not present on the display, the load control relay is open and the load is
disconnected.
