General Information
An active optoelectronic protective device is part of the electrical equipment which has to
be applied to those machines which contain the potential risk of bodily injury. They provide
protection by causing the machine to move into a safe operating state before a person can
get into a dangerous situation (EN 61496-1).
1.3
Definition of Terms
AOPD type 2
The EN 61496 describes two types of active active opto-electronic protective devices
(AOPD) with respect to the requirements concerning safety relevant parts of control units
(ISO 13849-1).
The AOPD type 2 fulfills the requirements of category 2 acc. to ISO 13849-1. A periodic
function test has to detect malfunctions in the safety function. In case of a failure, the next
machine cycle may not be released. A malfunction of the AOPD type 2 between the
testings can cause the loss of the safety function. In normal function, at least one safety
output of the AOPD type 2 has to move into the OFF-position if the sensor reacts or if the
power supply of the AOPD is interrupted.
Safety output (OSSD)
The part of the AOPD which is connected to the machine control and which moves into the
OFF-position as soon as the sensor part reacts during normal operation.
Start interlock
An equipment which disables the automatic machine start if the power supply of the
contactless active protective device is switched on or if it had been interrupted and
switched on again.
Start testing
A manual or automatic test which is performed after the contactless active protective
device has been switched on. It tests the complete safety-relevant control system before
the normal machine operation is induced.
