3.3.1.1.3.2 Open circuit detection. With input power
applied, the power switch on, panel switches S1 through S83 in the
normal position, and pins 1 through 83 on connector 15J1
successively grounded, the continuity lamp shall not light. The
continuity lamp shall light under the above conditions when
switches S1 through S83 are individually set to the test position
setting of each panel switch (A failure to illuminate the
continuity lamp shall indicate an open conductor).
Interlock test switch indicator. with input
