Table 2.12 lists internal elements which may be used singly to control output contacts for testing
purposes but are not available for SEL
OGIC control equations. Use SELOGIC control equations to
define MER, MTO, MTU, and MTCS. MER controls triggering of event reports. MTO, MTU,
and MTCS establish tripping conditions.
