Digital Gas Controller DGC3
1 Intended Use
The PolyGard
®
measuring, controlling and evaluating system DGC3 (
D
igital
G
as
C
ontroller) is used for the
detecting and warning of toxic and combustible gases and vapours in the ambient air, mainly in multi-story
buildings and underground car parks.
The DGC3 Gas Controller fulfills the requirements according to VDI 2053 (January 04), German regulations for car
parks, ÖNORM and NVN 2443 for the stationary monitoring of carbon monoxide (CO), nitrogen dioxide (NO
2
) and
combustible gases.
The Gas Controller is suitable for the connection of up to 16 digital gas transmitters of the DT5 series. Up to four
alarm thresholds are free programmable per measuring point (MP). Each alarm threshold can be assigned to one
of the maximum 14 alarm relays (RX). With its up to 5 analog output signals (4-20 mA) the Gas Controller can be
used for the continuously various activation of frequency converters etc.
The free adjustable parameters and alarm threshold enable a very flexible use in the gas measuring technique.
Simple and comfortable commissioning is possible thanks to the configuration with preset parameters.
Configuration, parameter settings and operation are done via the logical, easy system menu structure without
specific programming knowledge.
The intended sites within the ambient conditions as specified in the Technical Data are all areas being directly
connected to the public low voltage supply, e.g. residential, commercial and industrial ranges as well as small
enterprises (according to EN50 082).
The PolyGard
®
Gas Controller DGC3 must not be used in potentially explosive atmospheres.
Prior to commissioning, it is essential to consider the included guidelines for wiring and commissioning of this
hardware.
