SICK microScan3 User Manual

17 Glossary
CoLa2 CoLa2 (Command Language 2) is a protocol from SICK, with which
a c
lient (control, computer, etc.) can access suitable SICK sensors
via a network (TCP/IP) or USB.
Collision protection field The collision protection field detects oncoming industrial trucks
in narrow aisles based on the reference target. It has a greater
scanning range than a protective field. With the collision protection
field, collisions of industrial trucks in narrow aisles can be safely
prevented.
The collision protection field is not suitable for detecting people.
The collision protection field may only be used in narrow aisles.
Contour detection field The contour detection field monitors a contour of the environment.
T
he electro-sensitive protective device switches the associated
safety outputs to the OFF state if a contour does not correspond to
the set specifications, e.g. because a door or flap is open.
Control input A control input receives signals, e.g. from the machine or from
t
he control. Use of control inputs is how the protective device
receives information about the conditions at the machine, e.g., if
there is a change of operating mode. If the protective device is
configured appropriately, it will activate a different monitoring case
after receiving a new control input.
The control input information must be transmitted reliably. Gener‐
ally, at least 2 separate channels are used to do this.
Depending on the device, a control input can be realized as a
static control input or a dynamic control input.
Dangerous state A dangerous state is a status of the machine or facility, where
people ma
y be injured. Protective devices prevent this risk if the
machine is operated within its intended use.
The figures in this document always show the dangerous state of
the machine as movement of a machine part. In practice, there
are different dangerous states, such as:
•
Machine movements
•
Electrical parts
•
Visible and invisible beam
•
A combination of multiple hazards
Electro-sensitive protective
de
vice
An electro-sensitive protective device is a device or system of
devices for safety-related detection of people or parts of the body.
It is used to protect people from machines and facilities that pose
a risk of injury. It triggers the machine or facility to adopt a safe
state before a person is exposed to a hazardous situation.
Examples: Safety light curtain, safety laser scanner.
ESD Electrostatic discharge
ESPE Electro-sensitive protective device
Field set A field set consists of one or more fields. The fields in a field set
ar
e monitored simultaneously.
A field set can contain different field types, e.g., a protective field
and a warning field.
Hazardous area Hazardous area is any space within and/or around machinery in
whic
h a person can be exposed to a hazard. (ISO 12100)
