PICO-GUARD Controller
Instruction Manual
3.2 Security Protocol
Certain procedures for installing, maintaining and operating the
PICO-GUARD System must be performed by either Designated
Persons or Qualified Persons.
A
Designated Person
is identified and designated in writing,
by the employer, as being appropriately trained and qualified
to perform the specified checkout procedures on the PICO-
GUARD System. The Designated Person is empowered to:
• Perform manual resets and hold possession of the reset key,
code or other security means, and
• Perform the Daily Checkout Procedure (see Section 6).
A
Qualified Person
, by possession of a recognized degree or
certificate of professional training, or by extensive knowledge,
training and experience, has successfully demonstrated the
ability to solve problems relating to the installation of the
PICO-GUARD System and its integration with the guarded
machine. In addition to everything for which the Designated
Person is empowered, the Qualified Person is empowered to:
• Install the PICO-GUARD System,
• Perform all checkout procedures (see Section 6),
• Have access and make changes to the system configuration
settings, and
• Reset the system following a lockout condition.
Manual Resets
Manual Resets are performed using external reset switches
(System Reset and External Stop Device Reset). See Section
3.3.2 for reset switch mounting and location requirements, and
Section 4.3 for reset procedures.
A reset switch might be a normally open, momentarily held-
closed push button, although some applications may require a
level of supervisory control. In this case, a key switch can be
used where the key is secured and used by a Designated or
Qualified Person, as appropriate.
Using a key switch provides some level of personnel or
supervisory control, because the key may be removed from
the switch. This will hinder a reset while the key is under the
control of an individual, but must not be relied upon solely to
guard against accidental or unauthorized reset. Spare keys in
the possession of others, or additional personnel entering the
safeguarded area unnoticed may create a hazardous situation.
WARNING . . .
Reset Switch Location
All reset switches must be:
• Outside the hazardous area,
in a location that allows the switch operator full view of the
entire guarded area,
• Out of reach
from within the safeguarded space, and
• Protected
against unauthorized or inadvertent operation.
If any areas within the guarded area are not visible from
the Reset switch, additional means of safeguarding must
be provided, as described by the ANSI B11 series or other
appropriate standards. Failure to do so could result in
serious injury or death.
3.3 Controller Installation
3.3.1 Mounting the Controller
Mount the PICO-GUARD controller inside a lockable enclosure
with a minimum rating of IEC IP54. The control module may
be mounted onto standard 35 mm DIN rail or directly to
the backplate of the lockable enclosure, using the supplied
hardware.
3.3.2 Mounting the Reset Switches
Reset switches are user supplied. An optional SPST key reset
switch is available. See Section 2.3, Accessories.
All reset switches must be mounted outside the guarded area,
and out of reach from within the guarded area. The entire
safeguarded area should be visible from the Reset switch
location. If any areas are not visible, other means must be
used to ensure that no personnel are within the safeguarded
area when the system is reset (see Warning below).
Reset switches must be protected from accidental operations
and, depending on the applicable standards, from unauthorized
operation (e.g., through the use of a key, guards, or rings).
3.3.3 Mounting the Optional Remote Display
A remote display is available (see Section 2.3) for remote
monitoring of the system’s status. Up to four remote display
units may be connected to one controller. See installation
instructions included with the remote display for more
information.
