Use of Programmable Automation Controller in Painting spray booths
Ascon Tecnologic’s PAC (Programmable Automation Controller) has solved the control of sophisticated painting spray booths for the automotive industry. The system assures enhanced tasks such as:
Additional air flow, to achieve the required temperature and to avoid dust
Heat energy optimization
Static electricity Neutralization or reduction
Eco function to adjusts airflow and reduce cycle times.
Remote monitoring and control functions
The Ascon Tecnologic solution
The solution can be found by using controllers of microPAC series, Touch screen of OP-MT Series and DY web server to add the remote monitoring and control function. The PAC (Programmable Automation Controller) has been selected as most suitable device to control the most important functions including the management of:
Temperature, pressure and other analogue variables
Process status and safety devices
Control signals to burner and inverters, interlocks commands and alarms.
I/Os are then processed by the CPU, which includes PID and auto tune algorithms, profiles generation, mathematics, sequences and logics to execute typical functions such as normal or eco operation, pre clean, spray, wait, purge, bake, cool down and cleaning. All programmed by standard using an IEC 61131-3 compliant software environment
The DY web server grants quick assistance in case of maintenance allowing, by an internet connection, to upload, microPAC and OP programs, to do changes and to receive e-mails signalling booth or burner fault conditions.
The OP-MT Touch screen has been designed keeping the operator in mind with icons and images to represent actions and functions, on-line help and all the necessary information are always available. RTD temperature sensor completes the system by offering accurate temperature acquisition.
