Common questions:

– How to ensure a long life of the compressor?

– Using a softstarter for starting will reduce the accelerating

torque, thereby minimizing the mechanical stress.

– How to build a compact compressor unit?

– Using a compact softstarter like PSR or PSE will allow a

much more compact starting equipment than for instance

a Star-Delta starter.

Common questions:

– How to avoid extended voltage drops due to long

starting time?

– Use ABB’s softstarter equipped with current limit to

keep control of the starting current.

– How to extend the life of the driving belts?

– Our softstarters will reduce the mechanical stress during

start, thus avoiding slipping belts.

– How to ensure the operation of the fan?

– A softstarter with underload protection will detect broken

belts, making the operator immediately aware of the

problem.

Common questions:

– How to reduce the need for service and repair of the

conveyor belt?

– A softstarter from ABB will ensure starts with minimal

mechanical stress on the conveyor belt.

– How to avoid that the conveyor belt is running in the

wrong direction?

– Use a softstarter with phase reversal protection.

– How to improve the efficiency of the conveyor belt?

– Using softstarters with high and low current warnings

allow you to load on and off the conveyor belt.

– How to ensure a successful start even after longer times

without operation?

– A softstarter with kick start function will provide sufficient

torque to be able to overcome the initial high friction from

a temporary jammed belt.

Common questions:

– How to avoid voltage drops when starting?

– ABB’s softstarter will reduce the starting current

and thereby avoid the voltage drops.

– How to avoid water hammering when stopping?

– Use our softstarters equipped with an optimized

stop ramp. Or even better, with torque control.

– How to ensure high reliability in harsh environments?

– Use our softstarters equipped with coated circuit

boards to better withstand those environments.

– How to protect my pumping equipment in the best

possible way?

– Use ABB’s softstarters equipped with our special

designed protections such as overload, underload,

and locked rotor protection.
