Limitations of SELOGIC Control Equations
Any single SEL
OGIC control equation setting is limited to 17 Relay Word bits that can be
combined together with the SEL
OGIC control equation operators listed in Table 5.2. If this limit
must be exceeded, use a SEL
OGIC control equation variable (SnVm) as an intermediate setting
step.
For example, assume that the trip equation (SEL
OGIC control equation trip setting M86T) needs
more than 17 Relay Word bits in the associated equation setting. Instead of placing all Relay
Word bits into M86T, program some of them into the SEL
OGIC control equation setting SBA.
Next use the resultant SEL
OGIC control equation variable output (Relay Word bit SnVm) in the
SEL
OGIC control equation trip setting, M86T.
The SELOGIC control equation settings in the Group settings are limited to no more than 550
elements. In the Global settings, they are limited to no more than 50 elements. Table 5.4
summarizes this information.
