Chapter 3 Operation
DI SETTINGS
All the alarms can be configured with No.1 to No.8 alarm contacts. '0' means no alarm dry contacts. All the alarm dry
contacts provide NC (normally closed) or NO (normally opened) output and the default alarm dry contacts are given in
the following table.
Table 3-5 lists the alarms that you can scroll through in the ALARM SETTINGS/ALARM LEVEL menu, and also
shows their factory default 'Alarm Level' and 'Mapped Output Relay' settings.
