Thank you for selecting
SSi
P/N 13039 for your batch furnace, probe maintenance application.
You lubricate critical machine parts on a regular basis if you want them to last. Your zirconia
carbon sensor also requires regular maintenance. Buildup of carbon in the space between the
zirconia sensing element and the sheath, as well as at the sensing point, will eventually adversely
affect the proper operation of the probe. If carbon (soot) is allowed to accumulate to the extent
that atmosphere cannot penetrate to the sensing surface, control is impossible. The 13039 is
designed to prevent that from happening by accepting signals from the AC20 controller to
conduct a procedure to remove the carbon. It is intended for use with batch and continuous
furnaces. (See P/N 13036 for generators.)
SPECIFICATIONS
Reference air flow- 2 scfh max
Burnoff air flow- 10scfh max
Dimensions- 10" x 10" x 6"
Weight- 17.4 lbs
Actuation- N.C. inner door switch.
DESCRIPTION
The 13039 probe conditioning box is designed for use with batch and continuous furnaces.
Existing burnoff systems that are designed to work with a programmable controller cannot be
used as "stand alone" systems without significant modification. Further, most cannot provide
adequate air for burnoff because they simply switch the output of low flow reference air pumps
to the burnoff fitting without regard to adequate flow. Fig. 1 shows the piping and wiring
diagram of the 13039 PC Box

INSTALLATION
The compact JIC box is provided with flanges, each having two 1/4" mounting holes. Locate the
box within about 6 feet of the sensor, if possible. Avoid locations close to a source of
combustibles such as the vent pipe of an oil quench tank, or a natural gas fitting that could
develop a leak. Because the reference air pump aspirates air from its immediate vicinity to pump
to the probe reference air fitting, it is possible to experience a significant error in measurement
due to reaction of the combustible with air inside the probe. The result is a low reading of carbon
potential, which will cause the controls to add excess natural gas and overcarburize your work
piece.
OPERATION
Once you have conducted the brief startup procedure outlined here, you need only sit back and
enjoy safe, effective probe conditioning. No special programs to write, no scheduled operator
routines.
With the system wired as illustrated in Fig. 1, the furnace at normal operating temperature, and
the valve on the burnoff air flow meter closed, a burnoff at the AC20 is initiated. Set the burnoff
flow to about 5cfh. Observe the probe temperature and O2 millivolt reading, and adjust the
burnoff airflow until the millivolt reading is below 200 millivolts, preferably at 0. The
temperature will pass through a maximum as the flow is increased, then drop to a value close to
the normal probe temperature. Burnoff will now occur each time the inner door is opened, and
then closed. A manual burnoff can be conducted at any time from the AC20.
Refer to your GOLD PROBETM instruction manual for a complete description of probe
conditioning theory. System operation is described on Fig. 1.
