Project #0753
Page 1 Page 2

Project #0752 is restoring the GRS NX panel to a decent working order by using a Allen Bradley SLC-504 PLC. Some of the exit buttons are broke and just need new springs. This panel features the moving switch indicators, some of the motors are seized up and need to be fixed. It was rumor that when Cleveland transit removed these panels that they just sat outside. By the rust and such I would say that is correct. Most of the buttons at the top of the panels are broken but the switch heaters. The switch levers are broken but one of them and another is missing the knob. To learn more about GRS NX panels go here:
