Alarm selections can be connected to any Analog Signal (Table 6-3 Analog Signal Sources). Each alarm supports a setpoint type and value.

Alarm selections generate front panel alerts, support latching/acknowledge, with on delay timers. Select any Digital signal (Table 6-4 Digital Signal Sources) to disable the Alarm

Example: Using Math, Switch and Monitor blocks to achieve auto range functions

This example shows how to use the math blocks to scale the output in multiple ranges and uses a monitor and switch to select the desired amplification for the input. A relay is connected in parallel to the switch to provide an indication as to which range is currently being transmitted.
