• HART interface is now standard for configuration, information and test

• “1 sec.” response time is configured via HART.

• Default signaling for early clean optics warning optics

• Weatherprotection to be ordered separately

• GD10P “non HART” is obsolete from January 1st 2010

GD10P was brought to the industry back in 1996, and has since earned its reputation then as the benchmark for IR combustible gas detectors in areas where high safety and low maintenance are valued features. The GD10P has been virtually unchanged for13 years, and we are now proud to announce the release of an update of the electronics and software of the detector.

The basic function of the detector is unchanged, we use the same software functions to do the actual gas detection, but the microprocessor is now more powerful and we have added functionality for enhanced configuration and maintenance capability.

 HART

The single big change is the HART interface, which give users access to maintenance information. One example is the optical transmission level, which can be used to plan preventive maintenance of the detectors. Also information like actual gas reading, temperature, tag number, serial number and text fields can be utilised by a HART enabled AMS.

The HART interface is also used for extended configuration and testing of the detector:

• Configuration of Warning and Fault signalling (0 -3mA)

• Re-setting of zero point

• Loop current test mode (forced output)

• Selection of “5 sec” or “1 sec” response time (where applicable)

Any industry standard HART terminal can be used for commissioning and maintenance as the GD10P does not need any product specific device descriptor.

A command summary for all HART commands is available as a supplement to the standard operating manual.

Standard detector, individual configuration.

The GD10P has up to now been fully configured at the factory, which resulted in separate variants for each configuration. Over the years, the number of product variants increased as even minor changes to fault signalling on the 4-20mA interface required a separate ordering code, engraved on the stainless steel product label. This has a certain aspect of “keep it simple” to it, but there were absolutely no flexibility once the detector left the factory.

By opening up for individual configuration of the 4-20mA signalling and selection of the detector response time, both distribution network and end-users will see a reduction of stock as well as improved delivery times of detectors that formerly was regarded as “special versions”. A “special version” will now be a matter of configuration at commissioning
