Printing out configuration values
After installation is complete, a table of configuration values can be printed to insert
into one of the hanging plastic envelopes for future reference. The housing cover/
display needs to be removed to access to the display port, which is necessary to
retrieve the table of configuration values.
1. Unscrew the four captured cover screws using the supplied 3 mm Allen wrench
and remove the enclosure cover. Leave the display cable connected to the main
unit.
2. Insert a mini-USB cable (not included) into the USB connector on the bottom side
of the display PCB.
3. Connect the other end of the cable into a standard USB port in a laptop.
4. The Series IEFB insertion thermal energy meter will appear as a standard USB
drive on the laptop.
5. The file name with the configuration values is in the format of: serial number.txt.
The serial number can be found on the product label on the side of the meter.
6. Print out the configuration values and insert into one of the hanging plastic
envelopes for future reference
7. Re-attach the housing cover/display by tightening the four 3 mm screws.
Removing Series IEFB Insertion Thermal Energy Meter
1. To remove the meter from an installation without a valve, depressurize the pipe
and skip to step 4. If installed with a valve loosen compression fitting (4) and
withdraw the meter shaft fully through the valve until it stops.
2. Tighten compression fitting (4) snug.
3. Close valve (6) via valve handle (7).
4. Remove meter by unscrewing process collet (5) from valve (6).
Removing Thermowells
1. To remove the thermowell from an installation without a valve, depressurize the
pipe and skip to step 4. If installed with a valve, loosen compression fitting (2) and
withdraw the thermowell shaft fully through the valve until it stops.
2. Tighten compression fitting (2) snug.
3. Close valve (4) via valve handle (5).
4. Remove thermowell by unscrewing process collet (3) from valve (4).
