9.5.9 Change 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.
9.5.10 Change 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.
To enter a new value:
• From the Setup Sensor Menu, choose High Setpt for the selected
sensor and press Enter ↵ .
• To change the High Setpoint:
• Use the arrows ↑ ↓ to choose a character.
• Press Enter ↵ to advance to the next character position.
• When finished, press Enter ↵ again.
