Speed Switch SELOGIC Control Equation Setting
The speed switch SELOGIC control equation, SPEEDSW, defines the relay input
contact that is connected to the motor speed switch. The factory default setting allows
you to connect the speed switch contact to input IN3 at the relay or input IN7 at the
SEL-2600 RTD Module, if installed. The Speed Switch Trip logic, described in
Section 4: Settings Calculation, uses the result of the SPEEDSW SEL
OGIC control
equation.
