CTO trigger counter
This function controls the number of consecutive actuations of
the limiter. When the preset counter value is reached, the limit-
er disconnects the power supply permanently (no automatic re-
turn). The system can be switched on again after a manual reset
of the lock. By default (parameter 0) the limiter has the lockout
function set to 10 minutes after 5 consecutive disconnections.
The accrued value of the counter is reset in case of permanent
operation of the limiter longer than 10 minutes.

rent measured value of the disconnection counter.
