Honeywell SmartLine SLG 700 User Manual page 162

Instructions pertaining to R1.020000 and higher firmware:
a) If a field background is being used, disable it.
b) Using a user interface, select the correct Probe type from the table below:
Wire Probe Type
SINGLE-TWIST WIRE
MULTI-TWIST WIRE
c) If the probe length was changed, ensure that the correct probe length is being used and
reset the transmitter (see above for instructions on determining the correct probe length).
d) If a field background is desired, a new field background can be taken.
Instructions pertaining to be included with replacement of multi-twist wire probes:
a) Refer to Revision 4.0 of the SLG 700 SmartLine Guided Wave Radar User's Manual.
References below will be to this revision of the manual.
b) Determine the sensor firmware version of the transmitter (the procedure will vary
depending on the user interface. Consult the User's Manual, the HART Manual, or the FF
Manual.

c) Tools required – refer to section
d) Remove existing probe using an AF 8 mm wrench on the locknut and an AF 7 mm
wrench on the probe. Remove the existing end-of-probe hardware if it is needed for the
new probe.
e) Attach new probe – if the probe length has changed measure the length from the
reference plane to the end of the probe. Keep in mind that for a wire probe with an end
weight, the probe length is measured from the transmitter reference plane to the top of the
end weight.
f) If a field background is being used, disable it.
g) If the sensor firmware version is R1.020000 or higher, change the probe type to
MULTI_TWIST_WIRE, otherwise ensure it is WIRE.
h) If the probe length was changed, ensure that the correct probe length is being used and
reset the transmitter.
i) If the sensor firmware revision is R1.010000, an adjustment should be made to the
propagation factor and vapor attenuation (correlation parameter).
j) The propagation factor should be set to 0.9985 and the vapor attenuation should be set to
0.03300 if the model is SLG720 and to 0.04145 if the model is SLG726.

1.000000/1.000100: a change of probe type to multi-twist wire is not
supported.
1.010000: a change of probe type to multi-twist wire is supported but cannot
be completed only with only three-button/display operation. Either a HART
or FF user interface is required.
1.020000 and higher: a change of probe type to multi-twist wire is supported
with all interfaces.
