Figure 12 - Two Emitter/Receiver pairs
When operating with 2 E-R pairs, the wiring configuration shown in figure
12 must be respected. It must be made certain, that EMITTER 1 directs its
beam only to RECEIVER 1 and EMITTER 2 directs its beam only to
RECEIVER 2.
CAUTION
Make sure that EMITTER 1 never directs to
RECEIVER 2. To satisfy this demand, verify that the
BWS-T2 switches from GREEN to RED status, when
beam one OR beam two are interrupted separately.
