The ROUTE Module
Using a Temporarily Attached Pickup
Error Message
If the linked speed reference POINT does not precede the speed tagged dynamic data
POINT in the
GX
Series Microlog's ROUTE list, speed tagging is disa
bled. Speed tagging
is also disabled if the speed reference POINT has been downloaded to the
GX Series
Microlog in the proper hierarchy position but no data has been taken on it. In both
cases, the following message appears when attempting to collect data for the speed
tagged dynamic data POINT.
Microlog
Speed control point: >>Speed Tagging not taken.
Please take data.
Measurement aborted. Press OK to continue.
•
Press the
OK
function button to return to the ROUTE list.
Take data for the speed
reference POINT before continuing, or reconfigure the ROUTE in the @ptitude
Analyst host software and re-download.
Ensure that the speed reference POINT falls before any speed
tagged POINTs in the ROUTE list, and that data has been
taken
for the speed referenced POINT prior to any speed tagged
POINTs.
Speed reference POINT data (RPM) can be re
-collected as often as the user chooses,
however, speed tagged POINTs linked to the speed reference POINT are not updated
with a new speed value unless they too are re-collected after the speed reference
POINT is re
-collected.
Using a Temporarily Attached Pickup
Refer to Appendix D of this manual for important restrictions when using the CMXA
75-SL-Z2 Microlog in a Zone 2 restricted area.
If a magnetic or permanently mounted sensor is not used, the pickup should be placed
in contact with the machine before you initiate a measurement with an Enter button. If
the vibration probe is placed in contact with the machine after the measurement is
initiated, press the
Retake
function button and re-
take data for the same POINT again.
When using a hand
-held probe, it is important that you hold the probe steady and with
even pressure. The GX Series Microlog's high-speed acquisition requires only a few
seconds to collect an averaged FFT spectrum.
If the
Config
uration screen’s
Display Update
setting is set to
Multiple
and the vibration
probe loses contact or you are forced to discontinue collecting averages for other
reasons, such as an ambient temperature too hot to continue holding the probe in
place, the averaging process can be stopped at any time by pressing the enter button.
Recognizing this possibility, the GX Series Microlog divides by the number of averages
actually collected rather than by the number specified. Thus, as an FFT spectrum is
being averaged, the values stored and displayed are accurate for the number of
averages collected up to that point. If the averaging process has to be stopped after
three or four averages, the reduction in accuracy is usually minimal.
