Abstract
The modem control using solid-state circuit elements as used on electric mining shovels in the 4-to 20-cubic yard capacity range is described. The basic feedback principle is discussed and how this is used to obtain the desired characteristics required of a modem shovel control system is demonstrated. Maintenance and trouble shooting of the control system are discussed stressing that a logical approach in locating any malfunction must be followed in order to return the machine to productive work as soon as possible. The circuit elements not usually encountered, except in this type of control, are described in the Appendix.
