Resetting latched indicators and output relays
All indicators and output relays can be given a latching
function in the configuration.
There are two ways to reset latched indicators and relays:
1.
Move to the initial display, see Figure 2.2.1-1, from the
alarm list, by pushing the CANCEL key for approx. 3 s.
Then reset the latched indicators and output relays by
pushing the ENTER key.
2.
Acknowledge each event in the alarm list one by one, by
pushing ENTER the equivalent times. Then, in the initial
display, reset the latched indicators and output relays by
pushing the ENTER key.
The latchings can also be reset via the communications bus or
via a DI input configured for that purpose.
