Disconnect all power supplies before servicing equipment..
warninG
Safe operation of the device is only guaranteed when using certified
components!
notes
The product described hereby was developed to perform safety functions
as a part of a whole installation or machine. A complete safety system nor-
mally includes sensors, evaluation units, signals and logical modules for
safe disconnections. The manufacturer of the installation or machine is re-
sponsible for ensuring proper functioning of the whole system. Contrinex
cannot guarantee all the specifications of an installation or machine that
was not designed by Contrinex. The total concept of the control system
into which the device is integrated must be validated by the user. Con-
trinex also takes over no liability for recommendations which are given
or implied in the following description. The following description implies
no modification of the general Contrinex terms of delivery, warranty or
liability claims.
safety reGulations
This device must be installed and operated by staff who are familiar
with these instructions and with the current regulations for safety at
work and accident prevention.
Pay attention to applicable local regulations, especially regarding
safety measures.
The shock protection on the connected elements and the cable insula-
tion must be designed for the highest voltage applied to the device.
Opening the device or implementing unauthorized changes voids any
warranty.
The unit should be panel mounted in an enclosure rated at IP 54 or
superior. Dust and dampness may lead to malfunction.
Adequate fuse protection must be provided on all output contacts with
capacitive and inductive loads.
The safety function must be triggered at least once a month.
desiGnated use
The yrB-0330-242 provides a security-oriented interruption of a safety
circuit. It can be used for the protection of persons and machines in ap-
plications with active optoelectronic protective devices (AOPDs).
When used in accordance with its intended purpose and following these
operating instructions, this device presents no known residual risks. Non-
observance may lead to personal injuries and damages to property.

oPeratinG instructions
for multifunction safety relay yrb-0330-242
Muting operation
To connect max. :
3 AOPDs (active optoelectronic protective devices) 2-channel or
2 AOPDs 2-channel and 2 muting sensors 1-channel or
1 AOPDs 2-channel and 4 muting sensors 1-channel or
2 AOPDs 2-channel and key switch for stepping operation
additionally: Start button and machine contact with line fault detection
Broken wire detection on AOPD input
Outputs:
3 N.O. contacts
2 semiconductor outputs, protected against short circuit and overload
Multifunction device, different functions selectable by rotational switches:
protective operation, e.g. light curtains
protective operation with muting, e.g. conveyors
* signal sequence of muting sensors can be selected
* maximum muting time selectable
* override function via start button
stepping operation, e.g. on presses
* 1, 2 or 3 steps possible
* setting of number of steps possible via selector switch
Suitable to connect AOPDs of type 4 or type 2 according to IEC/EN
61496-1, crossfault monitoring in the AOPD
With under- and overvoltage detection and indication
reaction time: max. 30 ms
LED indication for rUN and channels 1, 2
Practical notes
Before removing the front plate, the person doing so must be dis-
charged to ground
For muting operation, the muting lamp must be conform to EN 61496-1
section A7.4
Every time an AOPD is not used, the two corresponding connection
clips S-1 / S-2 and S-4 / S-3 must be bridged, according to application
example "Stepping operation with one light curtain".
safety notes
Attention !
Not designed for installations where it is possible to go round the AOPD.
Settings have to be carried out by specialized personnel.
Settings have to be carried out with disconnected power supply.
