engineering units will be performed automatically based on the enumeration code returned by the sensor.
The scale and offset values shown here are applied on top of the scaling native to the sensor. For example,
sensors returning temperature will always return degrees Celsius. To convert to Fahrenheit instead, apply
scale and offset as illustrated above.
The timeout, in minutes, is optional. If zero, the timeout will not be monitored. If non-zero, and the time
since last transmission exceeds this time in minutes, then the BACnet objects assigned to this sensor will
reflect a Fault status.
The sensors have high/low alarm capability. If the alarms are not being used, then the only setup needed
is on the tabular list illustrated above. To set up alarms, click on the sensor number in the first column.
This will take you to the extended alarm setup page illustrated below.
The same sensor setup information found on the tabular list is also available here, in addition to alarm
settings. Enabling an alarm requires setting the Alarm Time to a non-zero value. User scaling entered here
is applied to alarm setpoints, as well as additional internal scaling based on sensor type and its
enumeration code. Therefore, the example here will display temperatures in Fahrenheit, and alarm
setpoints will also then be entered as Fahrenheit.
The sensor Transmit Period is entered in seconds. The Hysteresis is entered as a raw count. This value is
not scaled since the same hysteresis is applied to both sensor channels, which may have different units.
The raw count is A/D count at the sensor. As an example, a single 'count' for an RTD sensor is 0.0977
