Each contact output can be controlled directly using the select-before-operate output control function. The
output logic expression that normally controls the state of an output can be overridden and the contact
pulsed, held open, or held closed. This function is useful for testing purposes. An alarm point is available
in the programmable alarm function for monitoring when the output logic has been overridden. See the
Alarms chapter for more information about programmable alarms. Output logic override control is
achieved using the front-panel interface or BESTCOMSPlus. Use the Metering Explorer to open the
Control, Output Override screen. Refer to Figure 35.

Enabling Logic Override Control
By default, logic override control is disabled. Output logic override must be enabled before the control can
be used. Enabling of the output logic override control is not possible at the front panel. It can only be
enabled through a communication port using BESTCOMSPlus (Figure 35). Click on the Disabled button
next to the output you want to control. This button will change to Enabled and the following three action
choices will appear to the right: Reset, Set, and Pulse.
Pulsing a Contact Output
Pulsing BE1-11g outputs provides the user the ability to test the operability of an output without
energizing a measuring or timing element. This feature is useful when testing the protection and control
system. When pulsed, an output changes from the current state (as determined by the virtual output logic
expression) to the opposite state for 200 milliseconds. After 200 milliseconds, the output is returned
automatically to logic control.
