Apparatus for checking the operation of control circuits |
| abstract |
The disclosure describes apparatus for checking the operation of control circuits of the type used to actuate the hammers of a printer. A first gating matrix is addressed by a selector so that the control circuits are operated in groups during a plurality of sub-cycles of operation. Detectors which generate an error signal in response to the erroneous operation of each control circuit are connected to the gates of a second gating matrix arranged in the same manner as the first gating matrix. The selector also addresses the second gating matrix so that the detectors which generate error signals can be identified in an error register connected to the second gating matrix. |
