WARNING:
Channel B (1.B, 2.B, and so on) can’t be used on Virtual Channels. If you need
to use the channel B of a multiaxis sensor, like Voltage 2CH, Vibrating Wire + Thermistor,
and all others, you should use 2 separate channels during configuration.
ALARMS
Overview
•
NI400 can handle alarms of both channel (reading out of a determined range) and
device (malfunction, wrong configuration etc.)
•
Alarms can be recorded on Alarm logs and can be sent via SMS, EMAIL, FTP or acti-
vate through NI400’s Digital Output (refer to Chapter for more info).
•
A first configuration must be done in the Alarm Configuration page (on the web serv-
er, click on “Configuration” and “Alarms”). The following screen will be prompted.
Simple steps to configure alarms:
•
Select Output
•
Select “Delay”
•
Select “End”
Configuration
Figure 71
In the “SENSOR” section, it is possible to select how NI400 will handle Sensor’s alarm:
Enabling any of this checkbox will modify datalogger’s action:
• Send SMS will send an SMS with the Alarm
•
Send email will send an email with the Alarm, to specified recipient (see next section)
•
Upload on FTP will upload the Alarm Log’s row with the alarm triggered
•
Enable Digital Output will trigger the Digital Output terminal block to control an
external Alarm system
•
Frequency increase will increase acquisition frequency to gather more information
about the event that has triggered the alarm. Acquisition Frequency is set at 1 minute
when the channel is in ALARM. If the datalogger is configured to read different sensors,
and more than one sensor is in alarm, reading frequency will probably be lower.
