An interesting test was planned on Boxing Day at GSK (GlaxoSmithKline Pharmaceuticals) in Rixensart. Medicines and vaccines are made on this location. Beauty products and cosmetics are also manufactured on this site.
There are several TGBTs (low-voltage distribution boards) installed that are equipped with a net connection, in order to provide the various buildings with electricity. In addition, there’s also an emergency power supply with a generator. A UPS ensures that the power in the building does not fall away when an interruption occurs and the generators haven’t started up yet. In order to ensure that production is not compromised, this reliable system is of vital importance.
The steering of the TGBT is done via a PLC. Via Schneider, ARCsom was asked to write some new software for the PLC. We also tested the software on the installation. This test took place on December 26, while the production was shut down. Ronald and some GSK-technicians checked if everything was working as planned – and it did!
It was even quite impressive to witness a smooth switch from normal to ‘secours’, while power consumption was on a level of 800 A.
The test proved to be successful and the customer was satisfied with the result. The tension we all felt in the morning was gone: everyone back to holiday modus!
