OPTION NUMBER DESCRIPTION
STANDARD
EQUIPMENT
Single gas conditioner (dryer / NH
3
removal) for ozone generator supply
gas stream only. Includes mounting bracket for two dryers (Option 86
mounts on the back).
OPT 86
Single gas conditioner (dryer / NH
3
removal) for sample gas stream only.
Mounts on the back of the existing dryer bracket. Converts analyzer to
dual-conditioner instrument.
OPT 88
Single combination gas conditioner (dryer / NH
3
removal) for both the
sample gas and ozone supply air. Replaces the standard dryer for O
3
air and comes with mounting bracket.
The combination conditioner is a low-cost option for drying both the sample gas and ozone supply air with one
dryer. However, this dryer can only be used in applications where both sample and calibration gases (after
dilution) are at or near ambient and constant concentrations of oxygen (about 21%), because the ozone
generator needs a high and constant amount of oxygen to generate ozone properly. Stack applications or
industrial applications in which the sample gas has a significantly reduced or highly variable concentration of
oxygen need to use the separate dryer option 86. The combination conditioner needs to be specified upon
ordering the analyzer.
5.11. ALARM RELAY OPTION (OPT 67)
The M200EH/EM can be equipped with a set of 2 concentration alarms. Each alarm can be independently
enabled or disabled as well as programmed with its own, individual alarm limit point (see Section 6.14 for details
on programming the alarms).
The status of each alarm is available via a set of alarm relay outputs located on the lower right hand corner of
the analyzer’s rear panel (see Figure 3-2). While there are four relay outputs on the back of the analyzer, only
Two of the outputs correspond to the instrument’s two concentration alarms.
