1 I MPORTANT S AFETY W ARNINGS 1
WARNING! Read and understand this section prior to installing the QuadSafe
RM-4 system.
1.1. S AFETY W ARNINGS
The QuadSafe RM-4 module is a “ Type 4 ” safety device. It is designed to work with
safety devices to guard personnel working around moving machinery.
Whether a specific machine application and QuadSafe RM-4 installation complies
with safety regulations depends on several items, including the proper
application, installation, maintenance and operation of the QuadSafe RM-4. These
items are the responsibility of the purchaser, installer and employer.
The employer is responsible for the selection and training of personnel to
properly install, operate, and maintain the machine and its safeguarding systems.
The QuadSafe RM-4 should only be installed, verified and maintained by a
qualified person, as “ a person or persons who, by possession of a recognized
degree or certificate of professional training, or who, by extensive knowledge,
training or experience, has successfully demonstrated the ability to solve
problems relating to the subject matter and work.
” (ANSI B30.2-1983)
To use a QuadSafe RM-4 module, the following requirements must be met:
— The guarded machine must be able to stop anywhere in its cycle. Do not use an
QuadSafe RM-4 on a press with a full-revolution clutch.
— The guarded machine must not present a hazard from flying parts.
— The guarded machine must have a consistent stopping time and adequate control
mechanisms.
— Severe smoke, particulate matter and corrosives may degrade the efficiency of
safety devices. Do not use the QuadSafe RM-4 module and safety devices system in
this type of environment.
— All applicable governmental and local rules, codes, and regulations must be
satisfied. This is the employer’s responsibility.

RM-4 Installation and Operation Manual
— All safety-related machine control elements must be designed so that a fault in the
control logic or failure of the control circuit does not lead to a failure or danger.
— Additional guarding may be required for access to dangerous areas not covered by
the QuadSafe RM-4 module and safety device system.
— Perform the STI test procedure at installation and after maintenance, adjustment,
repair or modification to the machine controls, tooling, dies or machine, or the
QuadSafe RM-4 and safety device system.
— Perform only the test and repair procedures outlined in this manual.
— Follow all procedures in this manual for proper operation of the QuadSafe RM-4.
The enforcement of these requirements is beyond the control of STI. The
employer has the sole responsibility to follow the preceding requirements and any
other procedures, conditions and requirements specific to his machinery.
2 D ESCRIPTION OF Q UAD S AFE RM-4 2
2.1. D ESCRIPTION
The QuadSafe RM-4 provides protection for machines with more than one
opening to guard. It produces a single pair of OSSD (OSSD A, OSSD B) safety
outputs by receiving safety and auxiliary outputs from up to four STI 4600 family
of light curtains. The QuadSafe RM-4 is enclosed in a 3"W X 5.8"L X 4.3"H DIN
box with two rows of removable terminal blocks. The mode and configuration DIP
switches are located inside the box. For DIP switch settings, see
“Section 4.3.”
on
page 13.
The QuadSafe RM-4 module works with up to four independent safety sensing
devices identified as safety device 1, safety device 2, safety device 3, and safety
device 4. Each safety sensing device (light curtain) has two solid-state, current
sourcing type OSSD outputs identified as OSSD 1 and OSSD 2. The OSSD signals
conform to 24 VDC indicating Machine Run and 0 VDC indicating Machine Stop.

The QuadSafe RM-4 is primarily intended to work with the 4600 family of light
curtains, but it can operate with other safety devices that test its OSSD output,
including the following other STI products: the MC4700 Light Curtain and the
BeamSafe II solid state unit (BS2RC24).
For the QuadSafe RM-4 to act as the primary safety device, the safety devices used
with the QuadSafe RM-4 module must be configured in the Automatic Start mode
and have their MPCE function disabled. The QuadSafe RM-4 also provides
connection for the safety device power, auxiliary, and start signals.
2.2. R ESPONSE T IME
The response time is less than 1 msec. The response time is measured from the
time when any safety device transitions to the MACHINE STOP state to the time
that the QuadSafe RM-4 OSSDs are in the OFF state. The QuadSafe RM-4 controls
it’s OSSDs according to the state of the safety device OSSD inputs. The QuadSafe
RM-4 outputs are only active when all the selected safety device OSSD inputs are
active.
