Function of the Energy trip unit
3.4 Managing alarms and logs
Note
To allocate the OAC contact to the PTA overload pre-alarm, the contact is forced to
automatic mode and the contact opens when the alarm disappears.
Configuring trip alarms
Trip alarms can be configured from the HTD210H panel display, the HTP610H
configuration tool and by using the Modbus connection via a HTC3x0H
communication module.
The trip alarm activation and deactivation hysteresis is fixed and cannot be adjusted.
Only the priority level setting is necessary.
Trip alarm setting Default setting
Priority level None – low – medium - high High
Note
The trip alarms are signalled by a pop-up message on the embedded display of the
Energy trip unit regardless of the priority level setting.
Configuring custom alarms
Custom alarms can be configured from the embedded display and the HTP610H
configuration tool.
For all alarms, the activation and deactivation time delays can be set between 1 and
3000 seconds, at one-second increments.
