Configuration

"Overvoltage supervision"

The braking module has overvoltage supervision for the line supply, which stops the device if the voltage level is greater than 1.15 x UN.

Fault code 3 will be shown as the error message (See the "LED messages", “Troubleshooting”, page 36

). To differentiate between phase

loss and overvoltage error messages you can deactivate phase loss supervision by removing jumper 3 from the control card. If, after doing

so, there is a stop with indication via the red and yellow LEDs (fault code 3), this will then be due to an overvoltage.

0 Jumper open

⎯ Jumper closed

X Jumper in either position

Standard adjustment of the device:

Autostart and no stop in the case of phase loss

CAUTION

RISKS OF INTERFERENCE

• Jumper J3 can only be removed after the frequency inverter or the braking unit has

been turned off if the line supply has been cut-off by opening the series switches

(contactors, line supply switch, etc).

• To avoid a dangerous voltage rise in the devices located in the section that is not

powered up: power generation must be stopped.

• Jumper J3 must always be removed before removing jumper J7. If not, if phase loss

supervision is active, the "phase loss" fault remains displayed as long as it exists (it

is not memorized in the fault memory).

Failure to follow these precautions can result in equipment damage.
