Unused screw terminals must be tightened home.
6.3 Commissioning
New detectors and factory calibrated and checked.
The detector behaviour after power on is described in Table 3.
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.
6.4 Configuration of gas detectors
Detectors have two jumpers designed for configuration of the device – see Figure 9.
Other parameters of gas detectors are configured using dedicated software (Sigma Toolbox).
This software can be downloaded from the manufacturer's website

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.
