Control functions
8.1 Remote reset
The Remote reset of the trip unit and output contacts control function allows the alarm pop-
up on the trip unit and output contacts to be acknowledged following an event from the Trip,
Alarm or Operation section.
The reset command is given from the digital input.
Digital input settings
The digital input settings (RR/DI terminal) are accessible from the CONFIGURATION
DIGITAL INPUT menu of the sentinel Energy display or from the Hager Power setup software.
It can be set for one of the following control functions:
Remote reset (by default)
If there is a pulse on the RR/DI input, the reset to zero enables the trip alarm pop-up window
of the sentinel Energy trip unit to be remotely acknowledged and also allows the D0x contact
corresponding to the OAC alarm output contacts module to be reset.
Switching between profile A and profile B
If there is a state change on the RR/DI digital input, the protection profile switches from profile
A to B and vice versa.
Switching between tari meters T1 and T2
If there is a state change on the RR/DI input, the energy tari metering switches from the T1
meters to the T2 meters.
Inhibition of advanced protections
If there is a state transition on the RR/DI input to the high signal,, the inhibition command is
applied to the advanced protections configured for the inhibition.
For reset of the output contacts, refer to Chapter 7.10 Programming the OAC module.
