VOLTAGE REACTION
The stabilization of the output voltage coincides both on the HPS (2 wires) output terminals and
on a possible long distance outlet (4 wires) to eliminate the fall in voltage influence of the
connections. To operate the long distance stabilization first connect the opposite terminals on the
back of the machine following the indications at the voice INSTALLATION. The choice of the kind of
long distance stabilization can be operated by means of the buttons 4 wires and 2 wires at the
voice SENSE.
Notice that HPS corrects falls in voltage on the connections until 10% of the set up voltage to avoid
possible overheating of the same line. After exceeding this limit
HPS doesn’t guarantee that the
value of the output voltage is equal to the set up voltage and is visualized a signal of error (see at
voltage alarms).
2.7.2.
TYPE OF OUTPUT
There is only the three-phase output.
The output power is variable to type of the load, for resistive load the power is nominal power, for
inductor load is greater than the nominal power, for capacitor load is less than the nominal power.
2.7.3.
CONTINOUS OR INRUSH MODE
Using the "Inrush" switch you can select the operation of the machine, in particular you can
change the current limits as shown in the tables. When the LED on the inrush switch is lit the
machine is on Inrush mode and the HPS can give three times the rated current; when the LED is off
the output current continuously is higher. This button is disabled or there is not if the machine has
not the inrush capabilities.
