Signalling System Repairs – Can we help?
Signalling System Repairs – Can we help?..us the question we often get asked! Yes we can!
Below, is an image of a Siemens FF011 (FF Series) switching unit that monitors the inputs and outputs of a signalling system on a railway.
This is an example of a small PCB ready to be repaired and refurbished. These are sent to Greasley Electronics on a regular basis and have been for over 20 years now! We have to ensure that each board is doing the right thing. Not only railways, but we repair and refurbish for underground systems too. Our most experienced engineer, Neal knows all about these PCB Repair faults and has enjoyed the challenge over the years!
What is normally the fault?
Aged related components are often changed but sometimes the main integrated circuits are the fault so these have to be changed too. Each one is tested on a test rig.
