We removed an old SSD 545 DC drive controlling an Old Bull DC motor and replace this with a new Parker 400kW 890PX AC Inverter to drive a new Elin water cooled AC motor. An AC30 Inverter was fitted to the water cooling system to regulate the cooling water flow on the motor. All safety interlocks were accomplished within the 890PX and AC30. The 890PX having Safe Torque Off wired and enabled. The new panel was integrated into the existing system which utilised an Allen Bradley 504 PLC and Allen Bradley Panelview 1400e.

We were asked to Design, Build, Install and Commission a 37kW flood defence system (pump station).

The setup utilised a Parker SSD Ac30 Inverter and all the control programming that would normally have been done in a Programmable Logic Controller was now done within the AC30 Inverter using CodeSys.

The AC30 Inverter controls the Levels and has a summer and winter level setting, the speed is regulated on level on a PID loop, the AC30 controls and monitors the cubicle temperature and all trips within the panel. Linked to the AC30 is a Parker SSD TS3003 HMI Display which shows the operator all the set points and setup details, this also sends texts in the event of a fault or high water level.

After a machine move we got asked to look at a webster bennett control panel and main motor, the motor had been making a horrible noise and not running poroperly. After an hour it was diagnosed that the A1 and A2 had been reversed on the wires going to the motor and this had caused one of the motor hrc fuses to blow. Three new fuses and correctly wired and the unit ran fine. The control panel was integral to the machine and built by Square D in 1964.

This motor is an 11kW and has been running at around 12.35kW for quite a few years now, the motor is suffering from overheating and the terminal box wiring clearly shows signs of this. the extra kW are costing in the region of £800 a year in excess electricity. The motor wiring will not last much longer.

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 !
