DANGER
Before changing jumper positions, remove voltage from the equipment and wait at
least 5 minutes.
CAUTION
Never set jumpers to a voltage value lower than the inverter supply voltage, to
avoid continuous activation of the braking unit.

RIMMERS
Depending on the jumper configuration, each trimmer allows the fine-tuning of the braking unit voltage
threshold trip.
Jumper-trimmer matching is as follows:
Jumper Function
J3
Fine-tuning of pick-up voltage through trimmer RV2
J4 Fine-tuning of pick-up voltage through trimmer RV3
J5 Fine-tuning of pick-up voltage through trimmer RV4
J6 Fine-tuning of pick-up voltage through trimmer RV5
The rated voltage for the braking unit activation and its range to be set with the 4 trimmers is stated in the table
below:
Mains voltage [Vac] Jumper Trimmer
Minimum

481÷500 (4T) J5 RV4 730 783 861
230-500 J6 RV5 464 650 810
CAUTION!!
Max. values in the table above are theoretical values for special applications
only; their use must be authorized by Elettronica Santerno. For standard
applications, never change the factory-set rated value.
