TTK’s FG-OD cables are certified ATEX / IECEx according to the marking mentioned above, according to EN / IEC 60079-0, EN / IEC 60079-18 and EN / IEC 80079-34. 
Special installation precautions are required when working in explosive atmospheres, such as use of zener barriers, specific location of alarm and/or satellite panels etc. 
The client is responsible for verifying that the design and installation of the detection system, in an ATEX / IECEx classified zone, is consistent with the classification of the area. 
The client retains sole responsibility for its use of TTK’s products.

Sensor terminal parameters:

 a. Discrete output.

Note: 

It is very important to follow the output circuit polarity as 

shown below, with the positive (+) side of the circuit wired to the 

CH1+/CH2+ terminal and the negative side (-) wired to the CMN 

terminal. Otherwise, the output circuit will remain ACTIVE (or 

CLOSED) regardless of the state of the output channel.

The discrete output of FG-STAD is driven by the unit and 

designed to give an alarm signal.

Other faults: Leak and break sensor / bus simultaneous, 

power supply lost.
