AA 106 - P.S.E. and Anti-Leak Device. There is evidence in
the circuit of the same type of galvanic P.S.E. and anti-leak device
formerly used in the MA 101. In the MA 101 this took the form of two loops
of insulated wire of dissimilar metals wrapped around the switch board with
the fuse-delay switches. If water entered the unit, a galvanic effect
resulted between the two wires (CU and ZN) and relay was actuated. This
device ap-pears in the AA 106. Some of the test characteristics are known
and are shown in figure 224. |
