PROBE CONDITIONING SYSTEM MANUAL
INSTALLATION
Location
The compact JIC box is provided with flanges, each having two 1/4" mounting holes. Locate the
box within about six feet of the sensor, if possible. Avoid locations close to a source of
combustibles such as a natural gas fitting that could develop a leak. Wire and pipe the system as
shown on the enclosed diagram. If trim gas is added by a motor operated valve, the control
interrupt terminals can be used to interrupt power to the motor, if it is not a spring return model.
This will hold the additive gas flow constant during burnoff.
Commissioning
Locate the probe in the generator wall so that the indicated probe temperature is stable between
1400 and 1600oF.
With the power switch off, set the burnoff time T1 to 3 minutes, the cycle time T2 to 24 hours
and the Delay Timer TR106 to 10 minutes. Close the burnoff flow meter valve and turn on
power switch SW-1. Set reference airflow close to, or above full scale.
Adjust burnoff airflow to about 3 cfh and observe the probe millivolt reading. If it doesn't drop
well below 200mv (preferably to zero) before the burnoff time is up, increase the time until it
does during a subsequent burnoff cycle. (To start a new burnoff at any time, turn off the power
switch to reset the timer, then turn the power back on.) Observe the time for the observed dew
point to return to within 1oF of the set point, and set this value on timer TR106. Your system is
now operational. Values of 24 hours cycle time, 3 minutes burnoff time and 8cfh burnoff flow
are typical for this application. When operating at dew points lower than 35oF, it may be
desirable to reduce the cycle time to 12 hours or less. If you encounter difficulties, contact SSI
for advice and assistance.
OPERATION
When power is first applied, reference air starts flowing and burnoff timing (T1) starts with
timer contacts energized. On completion of burnoff, cycle timing (T2) and the delay timer (TR
106) start. When the delay timer times out, control is restored and timer T1 continues. To do an
immediate burnoff at any time, turn the power switch off to reset the timer, then back on to
initiate burnoff. Refer to the GOLD PROBETM instruction manual for a more complete
discussion of probe conditioning. We think you will be delighted with the performance of your
probes once you have installed this engineered conditioning system. If you have any questions,
suggestions or problems, your GOLD PROBETM team is only as far as your phone. Call us at
