the electrical connections are correct, and that any
moving parts are mechanically protected.
• For safety purposes, with the exception of adjustment
and tuning phases by staff authorized to intervene on live

adjustment and tuning phases to protect users from
electric shock.
4.1 - Starting with the power supply
Since the run command has been factory-enabled via a jumper,
the motor starts as soon as it is switched on.
The speed is adjusted with the local control knob (B 31/32 or
B 33/34 option) or a remote reference (0-10 V or 4-20 mA).
Power-up: the green indicator lamp is lit continuously.
The control terminals SDI1 and SDI2 (VMA 33/34) or 11 and 12
(VMA 31/32) are linked (unlocking).
4.1.1 - Automatic starting
By leaving the wire between control terminals 8 and 11
(VMA 31/32) or DI2 and +24V (VMA 33/34), the motor
starts running forward.
4.2 - Starting with remote volt-free
contact
Once it has been switched on, the motor starts in accordance
with the run command given by the closing of the volt-free
contact corresponding to the desired direction of rotation.
The speed is adjusted with the local control knob (B 31/32 or
B 33/34 option) or a remote reference (0-10 V or 4-20 mA).
