Set remaining settings equal to combinations of elements in the Relay Word via SELOGIC
Control Equations. You can clear logic settings by entering NA.
The following settings S(123) through A2(1234) can be set to equal any OR-combination of
elements in the Relay Word rows indicated in parentheses.
S(123) = ? Input into timer TS (TS output is Relay Word bit ST)
Settings A(12) through J(1234) are for Relay Word bits A through J, respectively.
A(12) = ?
B(12) = 50NLT ?
C(12) = 50NL ?
D(12) = ?
E(34) = 79RS+79CY+52AT ?
F(34) = IN6 ?
G(34) = ?
H(34) = ?
J(1234) = ?
K(1234) = ? Input into timer TK (TK output is Relay Word bit KT)
L(1234) = ? Input into an inverter (output is Relay Word bit !L)
A1(1234) = TF ? A1 output contact setting
A2(1234) = NDEM ? A2 output contact setting
