Glossary
AC
Alternating current.
Aggressive Fumes/Liquids
Gasses or liquids that are chemically reactive and may cause
corrosion in exposed machine parts.
Air Gap
The gap between the armature and the magnet. This air gap must
be precisely adjusted to a specific width, denoted as X. If the air
gap is too wide, the brake may not release torque. If the air gap is
too narrow, the brake may drag continuously.
Application
The machine/system in which the KEB device is to be used. For
brakes the application is typically the motor to which the brake is
attached.
Armature
The component of the brake connected to the magnet which
moves across the air gap to engage or disengage the brake.
When powered off the armature is pressed against the friction
brake assembly by springs causing braking torque. When
powered on the armature is pulled across the air gap by the
magnet and the brake releases.
AWG / Wire Gauge
American Wire Gauge. A measure of the thickness of a wire using
standardized sizes.
Branch Circuit Protection
Circuit protection for the portion of the electrical distribution
system that extends beyond the final branch circuit protection
device. A branch circuit is used to run motors or other appliances,
and is what is commonly found inside a building.
CE
European safety standards for products in the European
Economic Area. Manufacturers self-test products against these
standards to maintain CE certification. The CE mark indicates a
product meets EEA safety standards.
CEC
Canadian Electric Code. Safety standard for electrical installations
used in Canada.
Control Device/Interface
The COMBISTOP brake is controlled electronically by a control
device. This can be as simple as a switch, or as complex as a full
suite of control software.
CSA
Canadian Standards Authority, also known as CSA Group.
Organization that tests and certifies products according to
Canadian safety standards. The CSA mark indicates a product
meets Canadian safety standards.
Customer
The corporation or individual who purchased the COMBISTOP
brake.
DC
Direct current.
Device / KEB Device
The COMBISTOP brake described in this manual.
Drive Shaft
A mechanical component for transmitting torque and rotation from
a motor to other parts of a mechanical system.
Dry running
Operation in dry environments with no danger of dripping or
splashing liquids.
