General Information
Note!
There are two device variations described in this connecting and operating instructions.
The difference between the two devices is in their supply voltage. The TNT 35 is intended
for 24V DC operation. The TNT 35/7-24V is intended for 24V AC operation. The basic
remarks concerning the functioning and assembly of the safety system are valid for both
device variations.
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 optical 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 output
switching element 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.
