Type 2 Sensors

When type 2 sensors are used, two pairs are to be connected
for each LCU input circuit. They are tested automatically. The
test command to the sensor (terminals 14/16/26/28) can be
selected by simple connection to the adjacent terminals
(terminals 15/17/27/29) (test with 0 V-potential or plus-
potential), see fig. 8.

Fig. 8. Selection of the test command for type-2 sensors:
Command via 0 V-potential, command via +V-potential.
The single-channel switching outputs of the type 2 receivers
are connected to terminals 9 and 10 (pairs 1 and 2) and/or to
terminals 21 and 22 (pairs 3 and 4).
