5.3 Commissioning
Before power up make sure that all parts are tightly screwed (cable glands, blinding plugs and the detector
lid). All fixing bolts (for the detector lid and bushing) must be in place and firmly tightened to prevent any
self-loosening during operation of the detector.
New detectors and factory calibrated and checked.
The detector behaviour after power on is described in Table 2.
If a test of the gas detection system is required, supply test gas to the gas detector and make sure that the
detector behaviour is in line with the specification.
It is recommended that – if possible – the commissioning of a gasometric installation should
take place in conditions where there is no risk of explosion – e.g. during a standstill of the
technological installations.
For large systems it is recommended to carry out commissioning of the entire system in several steps with
successive connection and commissioning of subsequent detectors. It makes easy to reveal and remedy any
possible errors.
5.4 Configuration of gas detectors
Detectors have two jumpers designed for configuration of the device – see Figure 10.
Other parameters of gas detectors are configured using dedicated software:
Sigma Toolbox package for PCs with the Windows system,
Detector Toolbox for Android devices.
This software can be downloaded from the manufacturer's website https://www.atestgaz.pl/en/software .

Configuration of the current source
The detector is furnished with a source of electric current. Depending on needs the source can be
configured as a SOURCE or a SINK – see point 4.3.1.
Configuration by installing a jumper – see table below.
