Page 5: Product Description
E2611-CH4 Rev 21.06.2021 Product description Methane detector-transmitter E2611-CH4 is intended for early detection of leakages or accumulation of methane in indoor spaces. The instrument is based on a fully calibrated and temperature compensated semiconductor metal-oxide (MOS) gas sensor with high repeatability, stability and long lifetime. -
Page 6: Operating Conditions
E2611-CH4 Rev 21.06.2021 Operating conditions The device should be used in a non-hazardous (non-ATEX -rated) indoor area at the atmospheric pressure ±10%, <95 %RH, without condensation, and in a basic electromagnetic environment, where the latter is defined in EN 61326-1. Metal-oxide sensors cannot properly operate in a zero or low oxygen content atmosphere. -
Page 7: Installation And Connections
E2611-CH4 Rev 21.06.2021 Installation and connections 1. Detach the base of the enclosure by gently pulling along four guiding pins. 2. Attach the base to the wall with two screws (see drawings below). 3. Connect the power supply and external devices to the terminal blocks on the PCB according to the connection diagram below. - Page 8 E2611-CH4 Rev 21.06.2021 Jumpers OUT1 type (open: 4-20 mA; closed 0-10 V) OUT2 type (open: 4-20 mA; closed 0-10 V) Reset Modbus network parameters to default X4 terminals OUT1 4-20 mA / 0-10 V output OUT2 4-20 mA / 0-10 V output 0 V / 24 VAC Neutral (optional) RS485 A / Data + RS485 B / Data -...
- Page 9 E2611-CH4 Rev 21.06.2021 To power the instrument from an external 24 V power source, connect terminals 0 V and +U to the source. If an integrated mains power supply module is used, connect terminals L and N to the mains. NOTE! If the instrument is powered from mains, connect to 0 V and +U terminals only light external loads, which consume less than 30 mA in total, as the integrated mains supply module capacity is limited.

Page 11: Operation
E2611-CH4 Rev 21.06.2021 Operation For best stability, the gas detector should be powered permanently. If the instrument is left for a long time in an unpowered state, then after initial power-on the metal-oxide gas sensor needs some time to heat up and burn adsorbed contaminants. So for the first tens of seconds of a few minutes, an alarm activation may be possible. -
