6.2.2 Configuring alarm conditions (Threshold monitoring)
The device can trigger an alarm whenever a specified minimum or maximum threshold
is crossed. That way,
• alarm messages can be sent via SMS and / or e-mail (if GSM connectivity has been
established and properly configured)
• an unscheduled measuring data upload to your FTP server can be performed (if
GSM connectivity has been established and properly configured)
• up to two connected devices (e.g. a pump or a valve) can be triggered by the
internal relays
Alarm thresholds have to be specified for each channel individually.
Specify under Alarm Destinations which Internal Relay shall switch to trigger the
connected device and which type of alarm message shall be sent
(SMS and / or e-mail and / or data upload to FTP server).
If a maximum level is set, the activated relay will trigger a connected device to switch on
as soon as the max. level is exceeded. The device is switched off, as soon as the signal
falls back below the threshold. This process takes place vice versa for a minimum level.
The minimum and the maximum threshold cannot be assigned to different relays. If both
levels are set, each of the activated relays will switch as soon as one of the thresholds is
crossed, no matter which one.
A relay cannot be assigned to more than one alarm. If a relay is already included in an
existing channel configuration, it cannot be used in combination with any other channel
or switching input.
