Configuring an
alarm input
After an alarm input has been activated, it must be specified which input voltage
value causes an alarm and which actions are triggered by an alarm. Click the
respective Configuration button. The following window appears:
Proceed as follows to configure an alarm input:
Step Action
1 Specify the input voltage value which does, when present at the
switching input, trigger an alarm.
The input voltage threshold is 2.5 V. Any voltage value below 2.5 V is
interpreted as 0 V while voltages higher than 2.5 V are interpreted as
5 V. In order to ensure a reliable classification, the actual voltage values
should not be too close to 2.5 V.
2 Specify under Alarm Destinations which of the relays shall switch in
the case of an alarm and which type of alarm message shall be sent.
3 Confirm and save the settings by clicking the Save button.
The internal relay of single-channel loggers (LOG D-1) is always Relay 2!
A relay cannot be assigned to more than one alarm. If a relay has been already
assigned to a switching input, it can neither be assigned to the other switching
input nor be used for threshold monitoring (see section 5.2.2).
