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 3). The circuitry consists of a common which can be
connected to an output corresponding to each RF path. If multiple
RF paths 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 page 21 for
"Indicator Specifications". The electronic position indicators
require that the supply (20 to 32 VDC) be connected to pin 1 and
ground connected to pin 15.
