Index
The door monitoring output is not a safety-related output; it may not be connected to the
safety circuit. The door monitoring output is generally connected to a higher-level control
system to indicate the position of the doors (open/closed) on a visual display.
The dwell time is the time that the actuator must be inside or outside the operating distance.
The fault detection time is the time for the detection of an internal fault in the device. At least
one of the relay outputs is opened safely. The welding of one of the relay contacts is only
detected after the safety guard is opened.
Proximity device with defined behavior under fault conditions (see EN 60 947-5-3).
PDF proximity devices with automatic control that do not lose their defined behavior in spite of
several faults (see EN 60 947-5-3).
PDF proximity devices that do not lose their defined behavior in spite of a single fault (see EN
60947 5 3).
Equipment of safety class III is equipment on which protection against electric shock is based
on safety extra-low voltage and is equipment in which no voltages higher than the safety extra-
low voltage are produced.
Voltage of a magnitude that does not pose an immediate risk to people. It provides safe
electrical isolation from higher voltage power circuits and is used isolated from ground.
The safety output is a safety-related output that may be connected to the safety circuit. A
safety output can be switched via relay contacts or semiconductor elements.
Assured switch-off distance S
Distance from the active face within which the correct detection of the absence of a defined
object is achieved under all defined environmental conditions, manufacturer's tolerances and
internal component faults.
Assured switch-on distance S
Distance from the active face within which the correct detection of the presence of a defined
object is achieved under all defined environmental conditions and manufacturer's tolerances.
Corresponds to the risk time according to EN 60947-5-3. This is the maximum switch-off delay
for the safety outputs following removal of the actuator.
