• Before switching on the VARMECA 30, check that
the electrical connections are correct, and that any
moving parts are mechanically protected.
• For the safety of personnel, the VARMECA 30 must not
be switched on with the protective cover removed.
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).
4.3 - Starting with local run/stop control
(BMA 31/32, BMA 33/34 or BMAVAR
31/32, BMAVAR 33/34 option)
Once it has been switched on, the motor starts after the
control knob corresponding to the desired direction of rotation
has been pressed for one second.
The speed is only adjusted with the local control knob.
4.4 - Setting the speed
4.4.1 - External reference
Adjust the speed reference using the chosen reference
(0/10 V or 4/20 mA).
4.4.2 - Control knob options (B 31/32 or B 33/34)
and remote potentiometer option
Adjust the speed reference using the control knob or the 10
k
Ω
remote potentiometer.
4.4.3 - Internal speed control option (CVI VMA
31/32 or CVI BMA 33/34)
Adjust the speed reference using the Int. Spd. potentiometer.
Adjust the Max. Spd. or Min. Spd. potentiometers if it is not
possible to reach the desired speed.
