Customers employee replaced a CC001 fuse with a KTK10 fuse.
COST:
1- 30 hp vfd alarm relay card. (Robbed Peter to pay Paul.)
2- crude repairs of relay cards for radio control system. These fail often enough so I did not catch the first failure as being odd.:ashamed:
1- Instal of Isolating relay to prevent future damage to vfd alarm card. It was only controling small cube relays to begin with.
12 - hours to check every relay, every VFD, and every interlocking cord connection on 300' of conveyors looking for shorted equipment. Includes final checkout and test run after fix.
1 - each of L14-20C & P (why is it always the last item checked)
Same employee had replaced a twistlock cord end used for control interlock with a 480v 30 amp, then modified the original to fit his replacement. Resulted in short on control circuit and his replacing of 1 amp fuse with 10 amp.
