Unblocking Impulse Allocation for IFC

Overview
The activated unblocking impulse (for more details refer to
connected via the IFC-D/P card when using the operating modes 1 and 2. When working with other operating
modes, the following system behavior must be observed:
Stand-alone Equipment
In the stand-alone unit, an activated unblocking impulse (t
5A) is executed via the RXALR relay on the ALR module. That means, there is no relay left for the receiver
alarm. The receiver alarm is indicated as general alarm GENALR.
SWT 3000 Integrated in the PowerLink System
The receiver alarm output of the PU4 module (RXALR) can be routed to the unblocking impulse in the service
program PowerSys (refer to
The RXALR output can be ranked to an alarm relay.
If there is an unblocking signaling via RXALR and ALR card, the active position of the relay must be considered
(an alarm is active when the relay is de-energized).
