Alarms - Novus LogBox Wi-Fi Instruction Manual

10. ALARMS

LogBox Wi-Fi has four channels. It is possible to set a minimum alarm and a maximum alarm for each channel. Alarms will be displayed and can
be configured to trigger an internal Buzzer for audible warning and a Digital Output for user control.
The alarm configuration general parameters are described below:
● Buzzer Runtime: Allows you to set a buzzer runtime for each time the device enters an alarm situation. The configuration will be performed in
seconds, from 0 to 65000 s, where 0 means that the buzzer should not be triggered. The longer the buzzer runtime, the greater the battery
consumption during the alarm situation.
● Digital Output Mode: Allows you to configure the digital output to follow an alarm situation. This way, whenever the alarm situation is satisfied,
the Digital Output will be activated. The digital output will be disabled if no channel is an alarm situation.
When an alarm condition is satisfied, the
that satisfy the current state alarm situation. The
symbol indicates that since the device was powered on or since the last alarm status was cleared, an alarm occurred. The retentive alarm statuses
of each channel can be cleared through the display screens or through NXperience.
For each enabled channel, it is possible to enable a minimum alarm and a maximum alarm, according to the following parameters:
● Setpoint: Shows the value to be exceeded for the channel to satisfy the alarm situation.
● Hysteresis: Shows the barrier to be exceeded for the channel to exit the alarm situation.
After the alarms are enabled, they behave as follows:
● Maximum Alarm: The channel will enter the Maximum Alarm when the current value is greater than the Maximum Alarm Setpoint and will exit
the maximum alarm when the current value is less than or equal to the Maximum Alarm Setpoint minus the Maximum Alarm hysteresis.
● Minimum Alarm: The channel will enter the Minimum Alarm when the current value is lower than the Minimum Alarm Setpoint and will exit the
minimum alarm when the current value is greater than or equal to the Minimum Alarm Setpoint plus the Minimum Alarm hysteresis.
The alarm status information, as well as the maximum and minimum values reached in each channel, will be updated by any events that trigger an
acquisition, which may be readings within the log range or in the display update range. If a channel reaches a minimum or maximum value or an
alarm condition during an acquisition other than the log range, it may not be logged in the memory. Thus, statuses may indicate that the channel
has already reached one of these situations and the information is not available in a download.
