Using the instruction manual Validity of the instruction manual This instruction manual is valid for the optek-converter 156 only. Follow the instruction manual for every operation. If the converter is not used as described in this instruction manual, your safety and the converter function could be affected.
If the possible cause of risk can be specified, the corresponding pictogram preceeds instructions: Danger! Electrical voltage. This pictogram indicates danger due to electrical voltage. Caution! This pictogram indicates information on how to avoid material damage. Note! This pictogram indicates instructional or general advice. - 2 - optek-Manual--1004-1022-02--156-US-2017-12-11 www.optek.com...
For disposal, disassemble the system components and separate them according to different material groups. Dispose of materials according to national and local regulations. If no agreement has been made, products may be shipped to optek for disposal. - 3 - optek-Manual--1004-1022-02--156-US-2017-12-11...
The manufacturer is not liable for damage resulting from use contrary to inten- ded use. Following this instruction manual is part of the intended use. The content of all serial number plates on optek products is model specific and refers to the time of delivery. - 4 - optek-Manual--1004-1022-02--156-US-2017-12-11 www.optek.com...
Have faulty parts of the measuring system replaced immediately. Spare parts must comply with the technical requirements defined by optek. This is always guaranteed when using original spare parts. For maintenance and repair activities, attach a warning sign to the external release device to prevent re-commissioning of the converter.
Use only original fuses with specified current and triggering characteristics! When a fuse has to be exchanged, first try to detect the cause and clear the fault before exchanging the fuse. When work on live parts is necessary, use insulated tools only. - 6 - optek-Manual--1004-1022-02--156-US-2017-12-11 www.optek.com...
The converter determines the change of light intensity by means of photocurrent transmitted by the sensor. After taking the logarithm, a measurement signal proportional to the concentration in the process medium is obtained. The 156 provides four defined and one variable measuring range to be adjusted to your specific process parameters.

• The power supply socket is not provided with a first-to-mate last-to-break protective ground contact. You must therefore provide an external release device. • The converter is designed for continuous operation and has only to be switched voltage-free for maintenance purposes. - 19 - optek-Manual--1004-1022-02--156-US-2017-12-11 www.optek.com...

Lamp voltage must be adjusted to the cable length in order to compensate volta- ge loss in the cable. Too low lamp voltage can lead to wrong measuring results. Too high lamp voltage reduces the life of the lamp module considerably. - 22 - optek-Manual--1004-1022-02--156-US-2017-12-11 www.optek.com...
