Conveyor belt – Food and
beverage industries
Extend the life of your conveyor belt,
and gain the benefit of consistent
start-up regardless of whether the
belt is loaded or not. The soft starter
ensures gentle acceleration and
deceleration, reducing risk of product
damage due to jerky starts and sudden
stops. It also protects the couplings,
belts, and bearings against mechanical
wear.
The soft starter
• Prevents conveyor belt slap during
start
• Reduces stress on counter- balances
and weights
• Reduces electrical disturbance on the
supply, via a minimum start current
function
• Provides protection against
accidental running in reverse
• Detects broken couplings or
broken belts, and trips the motor
immediately
• Detects overload, or a jammed
or stalled conveyor, and protects
equipment by tripping the motor
immediately
Crusher and mill
– Mining
Maximise your crusher or mill
throughput by installing a soft starter
at the motor input. The soft starter
allows the motor to operate at its
upper thermal limit, while carefully
monitoring thermal capacity to ensure
motor protection. The crusher can
then safely ride through temporary
product overload situations
The soft starter
• Eliminates the need for special
control equipment, by connecting
motor thermistors directly into the
VLT® Soft Starter MCD 600 thermistor
input
• Extends the life of couplings, belts,
and bearings by gentle start-up,
minimizing torque transients
• Reduces electrical disturbance on the
supply
• Limits the demand on the supply,
especially critical on remote sites
supplied by generator sets
• Prevents damage due to
unintentional running in reverse, by
preventing start when rotation of the
3-phase incoming supply changes
• Detects broken couplings and
broken crusher belts via undercurrent
protection, and trips to prevent
further damage
