nSource of CurrentD HubsPFigure 28. The gang punch emitter is simply a switch with twelve positions. Each posi-tion is connected to a control panel hub. The switch is automatically operated by the514 so that the twelve positions are connected to the source of electricity, one at atime. The 12 hub emits an impulse at 12 time of each card cycle; the 11 hub emits animpulse at 11 time of each card cycle; etc.
The two following prolrlems are included so that you may evaluateyour understanding of Section 3. Make sure you understand each prohlemthoroughly before attempting to "wire" the control panel diagram.If there is any uncertainty alrout any aspect of the problem, consultthat part of the text related to it.23.
