importAnt notes
noTe
The UD10 with CGS Interface option and
CGS sensor is certified as a “Gas Detector”
and performance approved to standards
FM6310/6320, ATeX 60079-29-1, and IeC
60079-29-1.
noTe
only Constant Current type CGS sensors may be
used with the UD10.
CautIon
The sintered metal flame arrestor is an integral
part of the combustible gas sensor. Do noT
operate the gas detector if the flame arrestor is
damaged or missing, since the exposed element
is a potential ignition source.
CautIon
Silicone based lubricants must never be used on
or near the CGS sensor, since this can result in
irreversible damage to the sensing element.
CautIon
When used as a stand alone device, the high
alarm must always be programmed for latching
operation. When used in conjunction with a
Control Unit and configured for a non-latching
high alarm, the control unit must always latch and
require a deliberate manual action to clear a high
gas alarm.
