6.0 TEST INPUT
The BSRSA interface includes a test input. This input is
used to check the interface between the photo-electric
safety system and the machine. It electrically simulates
an obstruction in the light curtain. While in the normal or
run mode, the test input is jumpered (closed). It is
opened and closed when used for testing.
machine's control logic can verify that the safety output
relays did, in fact, cycle, thereby exposing any fault
before the next machine cycle.
This test should be conducted during a safe part of the
machine cycle, or at the end of the cycle. While the test
input is opened, power is removed from the light curtain
(both emitter and receiver). Once the test input is
closed, power is restored to the light curtain.
emitter and receiver may take a few seconds to re-
synchronize, and, consequently, the safety outputs may
take a few seconds to resume their normal state. The
device connected to the test input should have a dry
contact which is closed during the run mode and
momentarily opened during the test mode.
The test input is located on terminal XI, connections 9
and 10. If the test input is not utilized, a jumper should
be installed across these connections. (This feature is
seldom used and, therefore, a removable jumper is
installed at the factory.)
7.0 MONITOR/AUXILLIARY OUTPUT
A non-safety monitor/auxiliary output is also provided.
This is a solid state relay output which is closed when
the light curtain is clear and is open when the light
curtain is obstructed, a fault exists, or a lockout
condition is present. This output is provided on terminal
X1, locations 1 and 2. This output can be used for
display and status indication purposes. It must not be
used for safety-related machine control and switching
functions.
