Power P
The power limiter allows you to power the circuit when the total
power of the receivers in the controlled circuit is lower than the
one set on the limiter scale. Exceeding the set power consump-
tion threshold in a controlled circuit results in a disconnection of
the power supply to this circuit after a user-set time. The power
supply will be restored automatically after a preset time. If the
power consumed is still greater than the set value, the circuit will
be disconnected again.
Automatic disconnection will also occur if the power consump-
tion is 8 times higher than the set threshold and if the power
consumption exceeds 16 kW. The limiter is locked for 30 seconds.
Voltage UL/UH
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.
