CM performs the checkup
of ISM main contacts position and updates the “’ISM main contacts position” relay
status in the following cases:
In case Close command was applied from the CM. In this case the update is performed not later than in
150 ms after ISM main contacts closing;
In case Trip command was applied from the CM. In this case the update is performed not later than in 70
ms after ISM main contacts opening;
Periodically every 10 s in case no Close or Open command was applied from the CM.
In case application project requires to define main contacts position faster than the timing mentioned above it
is recommended to use auxiliary switches installed at the ISM. Position indication of ISM provided by CM can
be incorrect, in case CM is not operable due to absence of auxiliary supply.
