Loss of Sensing Voltage - Time Delay (sec). The value of this field determines the time delay between
when a loss of sensing voltage is recognized and the BE2000E responds according to the Hardware
Shutdown and LOS Option options selected. A time delay of 0 to 25 seconds may be entered in 1 second
increments.
Generator Overvoltage - Voltage Level (%). The value of this field is expressed as a percentage and
determines the level of generator voltage required to initiate a generator overvoltage condition. An
overvoltage percentage value of 105 to 120 percent may be entered in 1 percent increments. A generator
overvoltage condition lights the GENERATOR OVERVOLTAGE LED on the front panel and closes the
Alarm output at BE2000E terminals AL1 and AL2 after a delay of 0.75 seconds.
Metering, Operation and Alarms
The Metering, Operation and Alarms screen is viewed by clicking the Metering button or by clicking
Screens on the menu bar and clicking Metering/Operation. Information displayed on the Metering,
Operation and Alarms screen can be frozen by clicking the Metering button while viewing the screen or by
clicking Metering on the menu bar and clicking Disable Metering. Metering can be resumed by clicking the
Metering button or by clicking Metering on the menu bar and clicking Enable Metering. The Metering,
Operation and Alarms screen consists of two tabs: Operation and Alarm/Status.

generator
voltages and are the products of the voltage sensed at terminals E1, E2, and E3 and the Generator PT
ratio. All metering values are updated once each second. When single-phase sensing is used (System
Configuration screen, Sensing Voltage) and the BE2000E sensing voltage terminals (E1, E2, and E3) are
connected as shown in the Installation chapter, all of the generator voltage metering values will be
identical.
Gen Current (A). This metering value indicates the level of the B-phase generator current and is the
product of the current input to CT1 and CT2 and the CT ratio. Generator current is monitored through
BE2000E terminals CT1 and CT2.
