COMITRONIC-BTI RDX8 Notice Technique page 3

Launching year 2010
1. Application
RDX8 switch detects the opening of a safe access. It comprises a trans-
mitter and a receiver and is contactless. This device is the anti-fraud type
and does not work if a magnet is applied to try to inhibit it. The product
meets the essential requirements for the safety of Directive 94/9/EC and for
which a declaration of Conformity is available. Due to their low self-heating,
magnetic switches RDX8 well suited for high ambient temperatures (70 °
C with a temperature class T6), they never reach the ignition temperature
of the gas or dust. The RDX8 be used in Area 2/22 within the parameters
indicated in the table of electrical features. It provides 2 lines NO and NC
line redundant and synchronized.
2. ATEX Safety and MACHINE safety

Covered standards: EN 60947-5-3, EN 61241-1, EN 60079-15
Performance level : up to PL = e according to ISO 13849-1 associated with
a safety module (AWAX26XXL-EEX3)
Classification: up to PDF-M to EN 60947-5-3 and associated with a safety
module (AWAX26XXL-EEX3)
B10d = 25 million to 20% load (30 mA)
Time of service : TM = 20 years
Operating temperature : -5 ° C to +70 ° C
3. Using
The installation of this product requires that you have a skill in ATEX.
This system is designed to be installed on a door or a movable guard
machine. Before installation, you must perform a risk assessment to
ensure that the features of this device are appropriate criteria for use and
environment of the machine.
4. Zener barrier ATEX
The RDX8 is rated "nC / tD" it is not necessary to use a zener barrier.
However, it can be proved that the equipment never undergo alteration
throughout its life (eg mechanical shocks that would alter the seal). We
recommend using a zener barrier ZRX8 ensure safety. The case is a standard
size 45mm DIN rail mounted.
5. Directive Machine 2006/42/EC and Directive Atex
94/9/EC.
If the product is intended to RDX8 a dangerous machine then you must
ensure compliance with the Machinery Directive. In this case you must use
the safety controller AWAX26XXL-EEX3 that incorporates a dual-channel
zener barrier for ATEX and a controller discrepancy according to ISO 13849-
1. The case is a standard size 45mm DIN rail mounted.
6. Mounting and dismounting
Have two legs brackets, the two elements (transmitter and receiver) is
easily fixed using screws 4mm diameter (washers ZU4 provided). Tamper
screws and tool option. The receiver is equipped with a multiconductor
cable AWG23 diameter 5.5mm and length of 12m standard.
Datasheet of RDX8 switch
Thank you for your confidence in COMITRONIC-BTI products.

34 allée du Closeau - ZI nord des Richardets - 93160 Noisy le Grand
7. Maintenance and fixing
During the whole operating life of the machine, by respecting the frequent
checking, be sure that the device is still fully operational. The mounting must
be controlled to find any print of breakings, damages or manipulation.
If necessary, replace the device. BTI can not be held as responsible for a
damage on this device if the procedures described in this document have not
been correctly respected or if the device is used in an unusual condition.
The safety switches must be so installed that hey don't touch each other when
the doors are moving to avoid any damages. We advice to install mechanical
guides on the doors.
The respect of the frequent checking and of the fixing guidelines are necessary
to benefit of the warranty.
Every 6 months :
Switch off power. Check the cleanness of the device. Clean any dirtyness. Check
screws. Switch on again and check the whole circuitry functionning.
Check alignment transmitter / receiver. The distance between the two parts
when the door is closed must always be positive, we recommend 3 ~ 5 mm.
Restore power and check for proper operation of the circuit safe.
8. Installation
Installation of the electrical systeme and all safety switches must be done by
the responsible company operating on the industrial site.
