Process High | If Alarm 2 is a Process High Alarm, | Input Range Minimum | Input | |
Alarm 2 | the value of the process variable at or | to Input Range | Range | |

Process Low | If Alarm 2 is a Process Low Alarm, the | Input Range Minimum | Input | |
Alarm 2 | value of the process variable at or | to Input Range | Range | |

Band Alarm 2 | If Alarm 2 is a Band Alarm, the band | 0 to input span from | 5 units | |
| of process variable values, centred on | (program) setpoint |
| |
| the (program) setpoint, outside which |
|
| |
| the process variable will cause this |
|
| |
| alarm to be active (see Figure |
|
| |
|
|
|
| |
Deviation | If Alarm 2 is a Deviation Alarm, gives | input span from | 5 units | |
Alarm 2 | a value above (positive value) or | (program) setpoint |
| |
| below (negative value) the (program) |
|
| |
| setpoint. If the process variable |
|
| |
| deviates from the setpoint by a |
|
| |
| margin greater than this value, the |
|
| |
| alarm becomes active (see Figure |
