Notes
A light axis consists of a
transmitter and a receiver
with the following
designations:
L49C[I]… = light axis, complete
LS49C[I]…= transmitter
LE49C[I]… = receiver
Alignment indicator:
(’K’ see dimensioned
drawing)
Yellow LED =
light path free - with
reserve
Yellow LED, flashing =
light path free - no func-
tion reserve
