SELOGIC Control Equation Variables/Timers
Sixteen (16) SELOGIC control equation variables/timers are available. Each
SEL
OGIC control equation variable/timer has a SELOGIC control equation
setting input and variable/timer outputs as shown in Figure 7.23 and
Figure 7.24.
Timers SV1T–SV6T in Figure 7.23 have a setting range of a little over
4.5 hours:
0.00–999999.00 cycles in 0.25-cycle increments
Timers SV7T–SV16T in Figure 7.24 have a setting range of almost
4.5 minutes:
0.00–16000.00 cycles in 0.25-cycle increments
These timer setting ranges apply to both pickup and dropout times (SVnPU
and SVnDO, n = 1–16).
