The relay assigned to the pre-alarm is activated, its contact switches and, in the example
shown below for a basic structure, the warning lamp switches on. Press and the XX will
disappear and be replaced by (--) and the pre-alarm relay will go back to idle.
Now move the cursor to the right, pressing and moving it to relay 1t.
Activate relays 1t, 2t and FA the same way and check the correct engagement of the
respective devices connected to them.
After the tests are completed, press until the status screen disappears: any relays that
are left active during the check will in any case be deactivated when leaving the screen.
CAUTION
Remember that if you leave the screen using ESC, any changes to the enablement
status will be confirmed (statuses “
A"
and “DE”); any fail status (“
FA
”) forced
during the check will in any case be deactivated when you leave the screen.
