Introduction
Modular Gas Sensors are the key feature of the MTL GIR6000
Biogas Analyser design. They are designed to be replaceable,
on-site, with minimal interruption to the operation of the
instrument, given that the location of the instrument is in a
recognised hazardous area.
In addition to the main Gas Sensor modules there are three other
module types, namely, the Pump module, the Filter module
and the Link module. This document describes the replacement
process for any of these module types.
READ THE SAFETY INFORMATION OVERLEAF!
Do not begin work until you have read and understood the
information provided there.
These instructions should be read in conjunction with the
Instruction Manual – INM MTL GIR6000.
Initial instrument shutdown
To add or change any replaceable module, it is important to
follow the procedure described here.
1. Isolate the sample gas inlet supply - using the local manual
isolation valve.
2. Disconnect the sample gas inlet pipe from the analyser.
Failure to isolate the sample gas supply pipe
before disconnection may result in toxic
3. Leave the analyser running for 5 minutes (to purge air
through system)
Purging the gas analyser will result in gas readings falling to
zero, which may generate alarms.
4. Power down the analyser using the external AC power
isolation switch.
Failure to shut down the MTL GIR6000
before replacing a module may result in an

Module removal and replacement
It is advised that any person handling an unplugged
module should wear an ESD grounding wrist strap to
prevent inadvertent static damage to any of the module's
electrical components. The ESD COMMON GROUND jack
socket provided at the lower left corner of the inner door
may be used if the enclosure is provided with a suitable
ground connection.
Each module is held in place with two threaded bolts at the top and
bottom of its front panel. The modules are keyed and will only fit in
the door panel at the appropriate location. A Phillips or flat-bladed
screwdriver is required to loosen the bolts after which they can be
freed by hand.
The module should be drawn straight out of the panel (see
photograph), which will disconnect both the gas and electrical
connections at the rear of the module automatically.
Additional effort will be required to remove a Filter Module
because of the additional O-rings it uses. Remove the Module
by exerting equal force on the both the handle and top bolt.
