OGIC control equation variable timer input SV_ asserted; timer timing
on pickup time; timer output SV_T not asserted.
SELOGIC control equation variable timer input SV_ asserted; timer timed out
on pickup time; timer output SV_T asserted.
SELOGIC control equation variable timer input SV_ not asserted; timer pre-
viously timed out on pickup time; timer output SV_T remains asserted while
timer timing on dropout time.

Hexadecimal values are constructed with the highest numbered bit (e.g., LB8) being the least significant, as follows:
LB1 LB2 LB3 LB4 LB5 LB6 LB7 LB8
