Checking The Connections - Nice Mindy A60 Mode D'emploi

3.6) Checking the connections

The following operations entail working on live circuits;
most of these run on extra-low safety voltage so they are
not dangerous; however, some are mains voltage circuits,
which means they are HIGHLY DANGEROUS! Pay the
utmost attention to what you are doing and NEVER WORK
ALONE!
• Power the control unit and check that voltage between terminals
17-18 is approx. 24Vac.
• Check that the "OK" LED flashes rapidly for a few moments and
then that it flashes at a regular frequency.
• Now check that the LED's related to the N.C. (Normally Closed)
contacts are on (all safety devices active) and that the LED's relat-
ed to the N.O. (Normally Open) inputs are off (no command); if this
is not the case, check the connections and efficiency of the vari-
ous devices. The STOP input switches off both FCA and FCC.
• Release the leaves, take them to the halfway point and then stop
them; this way the leaves will be free to move in either the open-
ing or closing direction.
• Now make sure that movement occurs in the right direction, i.e.,
see whether the movement set on the unit corresponds to that of
the leaves. This check is of paramount importance, if the direction
