Step Procedure
6.
Disconnect LCD Board cable connector from
µ
FLO 2100767 Board
Display Port connector J5 (Figure 4–1, Item 9).
7. Using a 3/16” nut driver, remove four Display Board hexagonal mounting
standoffs. Lift Board from door mounted standoffs.
If Board is being returned to Totalflow for service, it is recommended that
attached ribbon cable be left connected and returned with Display Board.
8. To reinstall Display Board, perform procedures 1 to 7 in reverse order. DO
NOT over tighten screws. Once Display Board is reinstalled, apply power
to
µ
FLO and verify information displayed on LCD is correct. Adjust
contrast potentiometer R15 (Figure 4–1, Item 7) for optimum display.
To adjust display contrast, use an extra small screw driver to turn potentiometer
R15 (Figure 4–1, Item 7) completely clockwise, then move screw back counter
clockwise until screen is readable.
Replacing Integral Multivariable Transducer (IMV)
Under no circumstances shall the
µ
FLO IMV cover be removed. Removal of this
cover, and entry into interior of IMV,
voids IMV warranty
. If the IMV requires
servicing, the entire assembly must be removed from
µ
FLO, securely packaged for
shipping and returned to Totalflow.
Procedures
In the following procedure, the common name for a component or it’s jumper
number if available (abbreviated J) or part is followed by a number in parentheses.
This refers to the call out item number referenced on each drawing.
Instructions
Step Procedure
1.
Make sure the J1 (Figure 4–1, Item 16) memory backup jumper covers the
top two pins. This enables the memory backup.
2.
Using meter run installed Manifold high/low control valves, equalize
pressure to IMV. See Figure 4–4.
3.
Using
µ
FLO high/low tap valves, close off both lines. These two valves
connect Meter Run high/low output lines to
µ
FLO.
4.
Vent manifold to atmosphere using vent valve.
5.
Completely disconnect high/low Manifold lines from IMV.
