ELECTRICAL CONNECTIONS
Figure 51
also shows the 32 integral connection
terminals, in two rows along the top of the interface unit.
The terminals are numbered 1 to 32. Each terminal is
suitable for up to two (2) 2.5mm
2
(14 AWG) solid wires.
Crimped ferrules or tinning must be used on all stranded
wires.
Figures 52 and 53
show system block diagrams for the
BSRUA-2 Controller.
Figure 52
shows the configuration
for one light curtain.
Figure 53
shows the configuration
for two light curtains.
Figure 54
shows the terminal
numbers for the input and output functions (Input Power,
ac/dc, and the redundant safety outputs). These
functions and terminal numbers are the same for either
the one or two light curtain configuration. The necessary
jumpers for the different configurations are noted. They
must be installed properly in order to insure the correct
and safe operation of the system. Some jumpers may
be factory installed, and the user must insure that the
unit is configured properly for the intended use.
All connections between the BSRUA-2 and the light
curtain(s) must be made with the proper emitter and
receiver cables (ordered separately).
For the case where one light curtain is used, refer to
Figures 55 and 56
. These show the interconnection
diagram and the wire run list (WRL) and give the proper
terminal numbers and their associated functions for the
cabling between the GS-120 Series emitter and receiver
units and the BSRU-2A controller.
For the case where two light curtains are used, refer to
Figures 57 and 58
. These show the interconnection
diagram and the wire run list (WRL) and give the proper
terminal numbers and their associated functions for the
cabling between the GS-120 Series emitter and receiver
units and the BSRU-2A controller.
Be sure to observe the color coding shown to assure
proper operation.
