[ENG] 4.5. [DKSF 48.4 IU] Configuring Top and Bottom Margin of a Safe Range for a Temperature Sensor
To configure a top and bottom margin of a safe range for a temperature sensor, there is a need to go to the page «
» of a device web
TEMPERATURE
interface:
where:
Top Margin of Safe Range, °C – is a field for setting a top margin of a temperature range for each temperature sensor. A temperature range is used to
specify conditions for generating SNMP TRAP and Syslog notifications as well as e-mail and SMS notifications (in a device with an embedded GSM
modem).

On default
Bottom Margin of Safe Range, °C – is a field for setting a bottom margin of a temperature range for each temperature sensor. A temperature range is
used to specify conditions for generating SNMP TRAP and Syslog notifications as well as e-mail and SMS notifications (in devices with an embedded
GSM modem).

Status – displays a current status of a temperature sensor. Its possible values are:
Failure – a temperature sensor is not connected or does not respond;
Normal – a temperature sensor responds and a temperature value is within the margins of a specified range for this temperature sensor;
Above normal - a temperature sensor responds, and a temperature value is above a specified range for this temperature sensor;
Below normal - a temperature sensor responds, and a temperature value is below a specified range for this temperature sensor
After changing the settings, there is a need to save the parameters by clicking the button «

To prevent frequent triggering of a top and bottom margins, a switching hysteresis of
.
1°C is used
A hysteresis sets a «corridor» around a specified temperature, within the limits of which top and bottom margins of a safe range do not
respond to temperature oscillations. This feature allows to avoid frequent random notifications from a temperature sensor caused by natural
spontaneous oscillations of a temperature measured by a sensor. If a current status of a temperature sensor is «above normal», then a
threshold for switching a status is a specified temperature minus a hysteresis value. And vice versa, if a current status is «below normal», then
a threshold for switching is a specified temperature plus a hysteresis value. As soon as a temperature increases or decreases reaching a
threshold value (taking a hysteresis into account), thus leaving margins of a «corridor», a temperature status is changed.
