6-26 Modular Block System: Burner Management
Standard Function Blocks
Spurious signal sequence at BASE input
Spurious signal sequence at AuSt input
According to the alloted time base, the set time is
decreased (
BASE = 0) or increased (BASE = 1). The
counter value at the T_V-input is multiplied with the
time base, giving the required time.
Changing from “manual reset” ( AuSt = 0) to “automatic
reset” ( AuSt = 1) can only be achieved by a new
system start after a signal change at the AuSt input, i.e.
re-assigning the parameter, down-loading a re-linked
program and restarting the system.
