System and Control Options

9.5.9Change Low Setpoint

The Low Setpoint value is typically above the 4 mA value for the sen- sor. For example, if the 4 mA value is 50°F, the Low Setpoint might be 60°F. When the sensor crosses below this value, an alarm or event will occur, depending on the sensor configuration.

The default Low Setpoint for each sensor is -950.0. Values that can be entered range from:

•the 4 mA value + the Offset value (in the example, 50+5=55) to

•the 20 mA value + the Offset value (in the example, 90+5=95)

To determine these values, see 9.5.4 - Change 4 mA Value, 9.5.5 - Change 20 mA Value and 9.5.6 - Change Offset Value.

To enter a new value:

•From the Setup Sensor Menu, choose Low Setpt for the selected sensor and press Enter ↵ .

•To change the Low Setpoint:

•Use the arrows ↑ ↓ to choose a character.

•Press Enter ↵ to advance to the next character position.

•When finished, press Enter ↵ again.

9.5.10Change High Setpoint

The High Setpoint value is typically below the 20 mA value for the sen- sor. For example, if the 20 mA value is 90°F, the High Setpoint might be 85°F. When the sensor crosses above this value, an alarm or event will occur, depending on the sensor configuration.

The default High Setpoint for each sensor is +950.0. Values that can be entered range from:

•the 4 mA value + the Offset value (in the example, 50+5=55) to

•the 20 mA value + the Offset value (in the example, 90+5=95)

To determine these values, see 9.5.4 - Change 4 mA Value, 9.5.5 - Change 20 mA Value and 9.5.6 - Change Offset Value.
