Had the job of removing an old Siemens S5 control panel for a plastics extruder and replacing with a new modern Allen Bradley PLC and Panelview Plus HMI Screen. New modern SSD DC 690+ drives on Devicenet and Siemens Solid State Switches for the heaters. New panel was tight as the customer wanted extras so we did a back to back job between the steel work !

Had a weeks work in Denmark removing a Robot Spray System with all associated controls. Robot was a Kuboto Steel (taken over by Mitsubishi), area was a hazardous one with EXd motors and Intrinsic safety circuits. Robot cell had Sick Safety Lasers for entry exit on the conveyor system. Unit was shipped back to the UK and installed here with some new modifications.

Asked to have a look at a heater bank on a dryer for polymer material

Cable too small, cable wrong specification and circuit breakers too large

Clearly whoever did the original install shouldn’t be trusted to wire up a 13Amp plug !
