ELECTRICAL CONNECTIONS
The SRUB controller has twenty integral connection
terminals, in two rows, along the top of the unit. The
terminals are marked according to their intended
function. Each terminal is suitable for up to two (2)
2.5mm² (14 AWG) solid wires. Crimped ferrules or
tinning must be used on all stranded wires.
Figure 60
shows the system block diagram for the SRUB
controller.
Figure 61
shows the terminal numbers for
the various input and output functions.
Particular attention should be given to the jumper
placements for configuring MANUAL RESET and
AUTOMATIC RESET. These jumpers must be installed
properly in order to insure the correct and safe operation
of the system.
Note:
Improper installation of the jumpers may lead to
false indication of the two green LEDs (channel 1 and
channel 2). For example, both LEDs may be
illuminated, indicating both safety outputs are “on”
(closed), however, the outputs may actually be “off”
(opened) without the proper jumper configuration.
Figures 62 and 63
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 SRUB controller. All connections between the
SRUB and the light curtain (emitter and receiver) must
be made with the proper emitter and receiver cables
(order separately).
