The rear panel of the M501-TRS includes a terminal strip by which connections can be made to
the converters internal temperature alarm for more information on this alarm see Section 6.5).
• Connect the input leads to your alarm-sensing device (e.g. datalogger) to the center two
pins of the alarm output connector (see Figure 3-5).
• Make sure the load does not exceed the rated capacity of the relay.
3.6.2. Pneumatic Connections:
This section supercedes the information contained in Section 3.1.2 of the M101E Manual
- P/N 04740 Rev A.
CAUTION
To prevent dust from getting into the analyzer, it was shipped with small plugs inserted
into each of the pneumatic fittings on the rear panel. Make sure that all dust plugs are
removed before attaching exhaust and supply gas lines.
Sample and calibration gases should only come into contact with PTFE (Teflon) or glass materials.
They should not come in contact with FEP or stainless steel materials.
Figures 3-7 and 3-8 show the most common configurations for gas supply and exhaust lines to the
Model 102E Analyzer. Figures 3-9, 3-10 & 3-11 show the connections for units with valve options
installed.
Please refer to Figures 3-1 & 3.3 for the location of pneumatic connections at the rear panel of the
M102E and the M501-TRS.

SAMPLE
Connects the sample gas to the analyzer. When operating the analyzer without
zero/span option, this is also the inlet for any calibration gases.
EXHAUST
Exhausts the gas sampled by the analyzer. Connect to an outside area away
from people.
SPAN
On units with zero/span/shutoff valve options installed, connect a gas line to
the source of calibrated span gas here.
ZERO AIR
On Units with zero/span valve or IZS option installed, this port connects the
zero air gas or the zero air cartridge to the analyzer.
TO CONVERTER Sample gas leaves the M102E to be conditioned by the M501-TRS via this port.
