UEL Tab
The UEL tab is used to configure the unit’s settings related to operation of the
Under-excitation Limiting (UEL) function. The values entered in this tab
establish break points in a piecewise linear curve that defines the characteristic
curve for this function. See the generator manufacturer’s data for the proper
setting information.
Refer to
for more information on the operation of the UEL function.
• Under-excitation Limiting Enable – Select this check box to enable
over-excitation limiting. Tag UEL_En in the configuration table stores
this parameter. In addition to selecting the check box, which sets the
UEL_En
tag in the configuration table, the UEL_En tag in the Output
(Scheduled Write) Data table must also be set to enable this function. In
Series B deices with firmware revision 3.3 or earlier, the UEL limiter
operates if either the enable box is checked or the UEL_En tag in the
Output (Scheduled Write) Data table is set.
