4.5 CONTROL AND DRIVING SYSTEM
9 It controls the operation of the electrical motor and coupled electrical systems of your
compressor. It can be evaluated into two sub groups; electronic controller unit and starting system
controlled by this.
Electronic Controller Unit
9 It enables you to make all related operational adjustments of your compressor. Pressure and
temperature values, failures and service periods are easily traced.
In the enclosed number 2 booklet you will find all usage and adjustment data related with
controller unit.
Starter System
9 Your system is equipped with star-delta or inverter controlled start up systems. This system is
designed to protect your system from all kinds of failure situations of all equipments.
9
There is an Emergency Stop button in right of control panel for emergency situations. This button
is easily accessible.
9 As all contactor, thermal fuse and all cable connection elements are defined by code, they can be
easily traced from electrical wiring diagram and on the machine.
Wye - Delta Starter
9
Is used to avoid excessive power from network during start and for preventing the mechanical
damage that may cause by full speed start up.
9 When you want to start the compressor, first the star contactor and afterwards the main contactor
are energized the compressor motor is started up. Your compressor does not deliver air during
star period.
9 After 4-6 seconds the compressor reaches the normal speed, the star contactor releases and the
delta contactor is energized. This way your compressor is switched on full power.
9 When you want to stop the compressor the energy of the contactors are removed and the motor
stops freely.
Frequency Inverter Driving
9 In the inverter application, the motor speed is changed in the course of the pressure data received
from system. And constant air pressure is obtained in the compressed air system. This way the
most economic operation is obtained and the losses in other systems are prevented.
9
When you want to operate the system, the inverter is switched on and this allows reaching your
compressor to maximum speed from zero speed smoothly.
9 When maximum speed is reached, the compressor starts to produce air.
9 When you want to stop the compressor; again like start up the motor is smoothly decelerated and
stopped.
In the enclosed number 3 booklet; “Control and start up system” named group lists and
related electrical wiring diagrams, installation pictures and part lists of two systems are
included.
