The logical AND connection means that lower unit (Unit B)
calculates the logical multiplication (AND) of the safety
output information from upper unit(Unit A) and safety input
signal "b", which is input to lower unit. In the example of a
right picture, the safety output of Unit C is "a" AND "b" .
Connect L1 or L2 of upper unit to T41 of lower unit, and
connect GND of upper unit to T42 of lower unit. To set
Safety instantaneous outputs of the subsequent Unit in ON
state, its Logical AND Connection Preset Switch must be
set to AND (enabled) and High state signal must be input
to T41 of the subsequent unit.
