10.5 Selecting AL CNF Alarm Configuration Features

These bits offer the same selections for “SP 3” and “SP 4” as “SP CNF” did for “SP 1” and “SP 2”, except for the
last bit, which controls “SP 3” and “SP 4” LATCH reset.

1.“ALC.1=0” makes Alarm 1 (Setpoint 3) active above the Setpoint value.

“ALC.1=1” makes Alarm 1 (Setpoint 3) active below the Setpoint value.


When Alarm 1 (Setpoint 3) is assigned to place a band about the Setpoint 1 level (by setting “ALF.1=3”, described
in Section 10.6), “ALC.1=0” makes Alarm 1 (Setpoint 3) active ABOVE and BELOW the band (OUTSIDE the band),
with the chosen hysteresis for Alarm 1 (Setpoint 3) now inside the band. If “ALC.1=1”, Alarm 1 (Setpoint 3) is active
INSIDE the band, with the chosen hysteresis for Alarm 1 (Setpoint 3) now outside the band.

Figure 10-7 Illustrates the Alarm configuration for hysteresis.
