5-2 | IPS-4 Dual Bench (UV / IR) Analyzer
Under normal operating conditions, lethal concentrations of H2S
and other toxic gases/liquids from the sample stream may be present
within the sample system. The sample system is defined as all compo-
nents in the analyzer system through which sample gas passes.
Before working on the sample system, manually Zero the analyzer
(from the Calibration screen, select Start Zero Calibration and
press
ENTER
), isolate it (block it in) from the sample stream, and
disconnect the power. Follow this procedure prior to changing out
any analyzer components or replacing any parts (as part of regular
preventive maintenance), or when performing leak checks following
the replacement of instrument air or other adjustments to any of the
connection points in the analyzer’s sample system. If this is not pos-
sible, a breathing apparatus must be worn while servicing the
sample system.
If handling the circuit boards, do not subject them to static discharge.
The ideal solution is a static-safe work area. Since such areas typically
are not available at analyzer installation sites, the use of a wrist strap
connected directly to a ground is recommended. If a wrist strap is
not available, you should at the very least touch the metal chassis to
ground yourself before handling the boards.
