9.4.4 Earth Leakage Transformer Fault Alarm (only in TF-CDI)
This alarm can not be programmed. Computer plus is configured by default so that when it detects that the
secondary circuit of the WG earth leakage transformer is open and the I leak alarm is enabled, the alarm will
trip. The status of the alarm is displayed on Fig. 104.
9.5 Programming the alarm relay
There is only one alarm relay and it can be used with any "OR" combination of the available alarms.
– To open the relay setup menu in the Set Alarm list, select the Relay configuration option and press OK
see Fig.95.
– The list of alarms will be displayed (Fig.96) and you can assign the alarms that will make the relay switch
(ON) and which will not make it perform the switching action (OFF). The relay is switched when any of
the alarms assigned trips, provided that these are enabled and that the global enabling option is also
activated.
