4.7.2 Current limit

Linear limit (by potentiometer on the front fascia)

First of all, make sure that the load is connected.

In the event of use of an external potentiometer or an external 0-10 V signal, make sure that
the "Threshold current limit" setpoint is set to the maximum.

• Turn the linear current limit potentiometer (indicated on the front fascia

"I limit

Limit I")

completely anti-clockwise (minimum position which

corresponds to a minimum current).

• Apply a 0 V signal to the input and connect the supply voltage.

The rms voltage at the load terminals must be zero.

• Increase the input signal to 100 % (if possible).

The load voltage must represent approximately 15 % of the supply voltage.

• Gradually turn the current limit potentiometer clockwise and check that the current

is increased slowly. Set the potentiometer in order to obtain the maximum
admissible current for the load.

Warning

For the current limit setting, only use an ammeter giving the true
rms value to prevent risks of errors which may reach 50 %.

For a

three-phase installation,

care must be taken to turn each of the potentiometers

gradually in succession in order to retain the balanced currents in each of the phases.

Warning

For a "3 phase plus neutral" configuration, the neutral current for a

load with a high temperature coefficient can be 1.7 times greater than
the phase currents, limited by the current limit.

Take this into account when designing the installation.
