ABB Totalflow X Series Startup Manual page 2

Introduction:
This startup guide is to assist in the startup of any flow computer or
remote controller of the XFC (flow computer) or XRC (remote controller)
series. It is however, primarily intended for gas orifice applications. It is
hoped that this guide in conjunction with other drawings and
documentation that accompanies your order will result in a smooth
installation. If for some reason, you have questions that are not
answered in this guide or your other documentation, call your local
Totalflow representative or call the number listed on the back page of
this guide.
Installation & 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.
Physical mounting and piping:
1. Unpack
2. Inspect for damage and missing or incorrect components.
3. Determine where to mount the unit.
4. Install bracing for unit; (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 unit; Right port of unit is NORMALLY
high pressure (upstream side). Check the AMU model number to see
if it is designed for flow from left to right (4CYC) or right to left
(4AYC). You can also look on the transducer for (H or +) for high
side and (L or –) for low side. 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 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).
