PICO-GUARD Controller
Instruction Manual
13) o Initiate machine motion of the guarded machine and,
while it is moving, open (block) the beam through an
optical element. Do not attempt to reach into the dangerous
parts of the machine. Upon opening (blocking) the beam,
the dangerous parts of the machine should come to a stop
with no apparent delay. Upon closing (clearing) the beam,
verify that the machine does not automatically restart,
and that the initiation devices must be engaged to restart
the machine.
14) o Block (open) a channel beam and verify that it is not
possible for the guarded machine to be put into motion
while a beam is blocked (open).
15) o If USSI inputs are used, initiate machine motion of the
guarded machine and, while it is moving, generate a USSI
stop signal by actuating a external stop device. Do not
attempt to reach into the dangerous parts of the machine.
When the USSI signal occurs, the dangerous parts of the
machine should come to a stop with no apparent delay.
Clear the USSI stop signal, and verify that the machine
does not automatically restart, and that the initiation
devices must be engaged to restart the machine. Repeat
for all other external stop devices.
16) o Remove electrical power to the PICO-GUARD System. All
OSSD outputs should immediately turn OFF, and should
not be capable of turning ON until power is re-applied
and, if configured for Manual Power-up, a system reset is
performed (Auto Power-up requires no system reset).
17) o Test the machine stopping response time, using an
instrument designed for that purpose, to verify that it
is the same or less than the overall system response
time specified by the machine manufacturer. (Banner’s
Applications Engineering Department can recommend a
suitable instrument.)
WARNING . . .
Do Not Use Machine Until
System Is Working Properly
If all of these checks cannot be verified, do not
attempt to use the PICO-GUARD System/guarded
machine until the defect or problem has been
corrected (see Section 5 of the manual).
Attempts to use the guarded machine under such conditions
could result in serious bodily injury or death.
18) o If any decrease in machine braking ability has occurred,
make the necessary clutch/ brake repairs, readjust
separation distance (Ds) appropriately, record the new Ds
calculation on the daily Checkout Procedure card and/or
in Section 6.4 of the manual , and re-perform the Daily
Checkout Procedure.
19) o Examine and test the machine primary control elements
(MPCEs) and any intermediary controls (such as interface
modules) to verify that they are functioning correctly and
are not in need of maintenance or replacement.
20) o Inspect the guarded machine to verify that no other
mechanical or structural problems could prevent the
machine from stopping or assuming an otherwise safe
condition when signalled to do so by the PICO-GUARD
System.
21) o Examine and inspect the machine controls and
connections to the PICO-GUARD System to verify that no
modifications have been made which adversely affect the
System.
Do not continue operation until the entire checkout procedure is
complete and all problems are corrected.
