Description

Simatek Frequency Converter is an electronic accessory. It gives the opportunity to choose the desired chain speed within the limitations of the elevator. The frequency converter is particularly adapted for the requirements of the elevator as to operational optimisation, monitoring, and protection against breakdown.

 

By means of the frequency converter you will attain full utilisation of the elevator as to the desired capacity. The chain speed is adjusted so that the buckets will be filled optimally. In this way you will obtain the optimum utilisation of the elevator capacity.

 

At the same time you will ensure that the elevator does not run faster than necessary which means that service parts and moving parts in the elevator are not loaded more than necessary. The frequency converter will also ensure a soft acceleration/deceleration.

Avoid unnecessary expenses due to heavy breakdowns

The software of the frequency converter is especially developed to protect the elevator against breakdown. This is conducted by means of the software in the frequency converter which constantly monitors the power consumption. If an accident occurs which causes the power consumption to increase suddenly, the elevator will immediately be brought to a stop.

 

The software also monitors any slowly increasing power consumption caused by wear, product accumulation, or the like. In these cases the elevator will also be brought to a stop. The software will monitor according to a fixed limit in the parameters of the frequency converter, which is set at run-in.

Function

The frequency converter provides the opportunity of two operation modes.

 

Mode 1:
For the elevator which is fed with a continuous constant product flow.

 

Mode 2:
For the elevator which is fed with varying product flow, or if there is a risk of the elevator occasionally running the buffer bin empty of product. Most feeding systems only work optimally if there is product continuously in front of the feeding system.

 

Here you can change between two speeds, either a speed adapted to the maximum capacity or an idle speed, when there is not enough product to fill the buckets. At an idle speed the feeding system is stopped, and the elevator goes on at a low speed, until there is enough product in the buffer bin. This operation mode has to be controlled by level sensors in a buffer bin in front of the feeding system of the elevator.
