ABB Totalflow mflo Series Startup Manual page 2

Introduction:
This startup guide is to assist in the startup of the
computer. Through this guide will be references to status codes that are
displayed in different annunciator positions on the unit's display. Since
assignments can now be made to any of the eight annunciators, there is
no specific annunciator for a specific code. However, for those of you
familiar with previous assignments, units are typically shipped with the
assignments defaulted as you are accustomed to seeing. This pertains
more to communication's ports since users may have custom
applications assigned to the other annunciators.
Recommended Start-Up Sequence
HINT: Step 1 thru 22 is a recommended start-up sequence and some of
the steps do not go into any great detail. Some steps because detail is
not needed and some because more information is available later in the
Start-Up Guide. For example there are later topics for installing and
wiring the RTD, installing the main battery, solar panel installation plus
other information. So, scan through the guide to see what information is
available before you begin the installation. Also keep in mind that units
on a RS485 bus may not have a battery or solar panel since they can be
powered from a remote power source such as another
does contain a battery and solar panel.
Physical mounting and piping:
1. Unpack
2. Inspect for damage and missing or incorrect components.
3. Determine where to mount the
4. Install bracing for µFLO (pipe saddle, direct mount, pipe driven in
ground). Attach U-bolts to 2" pipe using silicone spray or Teflon tape
to prevent galling. (See Figures 1 & 2)
5. Mount manifold to bottom of the µFLO. Since the µFLO can be
ordered with the flow going left to right or right to left, verify direction
of flow by looking at the transducer tag that shows a (+) and (-).
Plus(+) indicates the high side (upstream side), therefore flow is from
(+) to (-). For direct mount manifolds, the direction is very important.
(See Figure 3 for a typical manifold configuration)
6. Connect stainless steel tubing from manifold to orifice tap valves.
With the manifold equalized to avoid damaging the µFLO's
transducer, apply pressure to the manifold and check for leaks. For
best measurement, use large bore, short, equal length gage lines
with a downward slope to taps (at least 1" per 3 feet).
