5.5 Binary Outputs
Binary Output for Ground Fault
The device consists of 2 binary outputs for ground-fault indications. 1 BO is a CO type binary output and the
other BO is a NO type spare binary output.
The ground-fault binary output is user-configurable as a latch or wipe type. Refer to 5.4.9 BO Type Configura-
tion (for Ground Fault) for more information.
These binary outputs are connected to an RTU to indicate the fault status to a remote monitoring station.
NOTE
i i
Some RTU/Control system requires a pulse input to sense and transmit fault signal from SICAM EFI to
remote monitoring system. For such systems, the device is provided with a Wipe type BO operation (also
called Fleet type BO). When BO type is configured as Wipe, ground fault BO remains closed for 500
ms. To enable this function, you must configure Wipe type BO using DIP switch. Refer to 5.4.9 BO Type
Configuration (for Ground Fault).
Binary Output for Battery Health Check
A dedicated binary output is provided to indicate battery health remotely. This BO is connected to an RTU
to indicate the battery status to a remote monitoring station (SCADA). When battery is healthy, the BO is
normally open. When the battery is under low battery condition, the BO is closed.
Binary Output for Signal Lamp
The signal lamp binary output is used to connect to a signal lamp for better fault indication visibility.
Siemens provides the signal lamp accessory which can be connected to the device signal lamp binary output.
The Siemens signal lamp is battery-powered and does not need any external power supply for operation. The
signal lamp has a day time (under bright sunlight) visibility up to 70 m and night time visibility up to 300 m.
Distance measured in line of sight vision under clear weather conditions. For signal lamp ordering options,
refer to SICAM EFI - Spares and Accessories, Page 18.

In 6MD2311-1BB00-0AA3 and 6MD2311-1BE00-0AB6 MLFB variants, terminal X6 is a spare BO that can be
used as either fault BO (wipe/fleeting type) or signal lamp output (latch/permanent type).
21 Either ground fault or signal lamp output can be connected to this terminal for 6MD2311-1BB00-0AA3 and 6MD2311-1BE00-0AB6
