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).
