The PCU process controller is specifically designed by PINTSCH ABEN to control and monitor electric point heating installations. The programmable PCU is mounted in every INSV control cubicle which supplies the electrical power for the heating elements, mounted on a number of points located within an area of about Ø500 metres.
The modular PA-Line system design enables all possible levels of functionality the customer can require. PA-Line includes a SW module for voltage control, a NFS module for manual override, SEM modules for current measurement and EI/O modules for extension of digital in-outputs. Using ERM modules extension of a local system is possible up to 144 different element groups using 7 temperature control loops.
The PCU processor is programmed with reliable, stabile controlling software specifically written for point heating application. You operate the PCU with a user-friendly 4-line control menu display with control panel. Main functions can be operated with control buttons. The control menu informs you about the pre-set switch on/off temperatures for wet and dry frost conditions. You can read out all measured current- and temperature values, reprts and failures. LED indicators inform you about the actual operational status of the installation.
To the PCU an area detector and sensors for rail and ambient temperature are connected. Using these input signals, the PCU switches the heating on and off automatically. You can plug your laptop into the PCU to diagnose the installation. The PCU is connected to a PC in the local control room or a telephone dial/GSM modem for remote control and monitoring.
