The first four items define the possible functioning modes of the alarm relay:
Force OFF It blocks the relay in the de-energised state, the contact between the terminals 3
and 4 is always open.
Force ON It blocks the relay in the energised state, the contact between the terminals 3 and 4
is always closed.
Energized on error The functioning of relay RL3 is controlled by the error condition of one or
more parameters, selected among those listed below at the Source item.
By selecting this functioning mode, the relay RL3 energises and the contact between
terminals 3 and 4 closes, in case one or more selected parameters go in error. In
normal conditions, if the selected parameters are not in error, the relay is de-
energised and the contact between the terminals 3 and 4 is open.
De-energized on error The functioning of relay RL3 is controlled by the error condition of
one or more parameters, selected among those listed below at the Source item.
By selecting this functioning mode, the relay RL3 de-energises and the contact
between terminals 3 and 4 opens, in case one or more selected parameters go in
error. In normal conditions, if the selected parameters are not in error, the relay is
energised and the contact between the terminals 3 and 4 is closed.
The current mode is indicated by an asterisk (“ Energized on error ” in the example): to change
