Electronic Position Indicators
The electronic position indicators consist of optically isolated, solid state relays which are driven by
photo-electric sensors coupled to the mechanical position of the RF path’s moving elements (see
Figure 2-2). The circuitry consists of a common which can be connected to an output
corresponding to each RF path. If multiple RF paths are engaged, the position indicator
corresponding to each closed RF path will be connected to common. The solid state relays are
configured for AC and/or DC operation. See “Indicator Specifications” on page 25. The electronic
position indicators require that the supply (20 to 32 VDC) be connected to pin 1 and ground
connected to pin 15.
