Connecting Signals and AC Power
Refer to Figures 3-1 and 3-3 while wiring the Probe Heater Assembly.
This procedure assumes the Heater Assembly has already been in-
stalled on the HAG Probe.
To ensure easy removal of the Heater Assembly in the future, use at
least 60 cm (2 feet) extra conduit (
North American installations ) or
cable ( European installations ) at the Heater Assembly Junction Box.
North American installations
Flexible conduit suitable for the location can be used between the
Heater Assembly Junction Box and any rigid conduit. An alternative
is to use TEK cable for the entire distance.
European installations
Heat resistant cable and Ex d cable glands must be used, suitable for
85 °C (185 °F).
Any electrical connections, adjustments, or servicing of the analyzer/
HAG Sample Probe while it is energized or de-energized should be
performed only by properly trained and qualified personnel using
materials and methods specified and approved by the Owner Company
and the local electrical inspection authority.
Wiring Sample Probe Heaters Controlled by Analyzer
This wiring procedure is for HAG Probe installations used with Model 931
or Model 932 Analyzers.
For Model 919 or Model 920 Analyzers with a HAG Probe, refer to the
“Model 919/Model 920 Analyzers with Heated Acid Gas Sample Probe”
Manual Supplement in the “Supplemental Information” section of this
manual. Also, refer to Final “As-Built” drawings in the “Supplemental
Information” section of the analyzer or HAG Probe manual.
