‡ For Indicator-Totalizers Only
‡ For Indicator-Totalizers Only
‡1. BONNET MOUNTING SCREWS (#2)
located beneath the
indicator-totalizer bonnet lid, should be removed and the entire bon-
net (#1) lifted off of the transmitter. Replace the o-ring seals around
each of the four screws (#3) and at the bottom of the bonnet (#4) and
cover each of the new o-rings with a thin coat of silicone grease.
‡2. INDICATOR MOUNTING SCREWS (#6)
and shake-proof wash-
ers (#7) holding the indicator-totalizer unit (#5) to the transmitter
base (#10) should be removed and the unit lifted off, exposing the
A-drive gear (#8) attached to the top of the driven clevis shaft (#28).
‡3. METER CHANGE GEARS (#8 & #9)
should be inspected for
any sign of wear. The A-(drive) gear (#8) is attached to the top of
the driven clevis shaft (#28), and the B-(driven) gear (#9) is attached
to the bottom of the indicator (#5). The position of the A-drive gear
should be checked and adjusted if necessary to position the top face
of the gear 1/8 inch below the top surface of the transmitter base
(#10). The position of the B-driven gear top face should be 1/8 inch
below the bottom of the indicator-totalizer.
‡4. INDICATOR-TOTALIZER
unit (#5) should be cleaned thoroughly
using a mild soap and a soft brush. Under no circumstances should
the entire unit be immersed in the soap or should any metal object be
used when cleaning and inspecting the internal parts of the indicator-
totalizer unit.
‡5. GEARS
within the indicator-totalizer unit (#5) should be
inspected carefully. If any excessive wear is visible on the gear teeth,
and other wear points, the unit must be returned to McCrometer for
repair.
IX. INSPECTION
of all internal parts that may be replaced in the field
has been accomplished at this point. Should any of the parts upon
inspection, appear to be damaged or excessively worn, they must be
replaced to assure proper operation and prevent further damage.
X. REASSEMBLY
is necessary at this point. Before reassembling, make
certain that the unit is cleaned of any dust or dirt. Cost for replace-
ment parts not covered by warranty are available from current parts
and price list. If it is determined that the unit should be returned for
repair, please notify McCrometer prior to shipment. Each unit must
be properly packaged to prevent damage to the unit in shipment.
1. TOTALIZER DRIVE MAGNET ASSEMBLY (9)
should be checked
again to make certain it is properly set to drive the totalizer (#4). (See
step VII- 4).
2. TOTALIZER BASE CUP (#5)
can be placed back in the totalizer
bonnet (#1) on the totalizer assembly (#4) after the desiccant capsule
and the base cup o-ring (#6) are replaced and the new o-ring (#6) has
been covered with a thick coat of silicone grease. Be sure o-ring (#6)
is on base cup (#5) properly. When reinstalling the cup (#5), put two
drops of super glue on the inside edge of the bonnet 180° apart and
push cup firmly into the bonnet and hold for 30 seconds.
3. BONNET ASSEMBLY (#1)
should be cleaned and replaced on
the transmitter (#10). Bonnet o-ring (#2) should be replaced and the
new o-ring (#2) covered with a thin coat of silicone grease. Secure
four screws (#3).
‡4. CHANGE GEARS (#8 & #9)
should be checked again to make
certain they are in proper alignment (see section VIII-3). The gear
teeth should be lubricated with a light grease to assure longer life.
‡5. INDICATOR TOTALIZER
mechanism (#5) should be placed on
the transmitter base (#10) with the mounting screws and shakeproof
washers (#6 & #7). Do not tighten mounting screws (#6) until the
gear mesh has been properly adjusted. To adjust gear mesh, slide
the indicator-totalizer mechanism (#5) towards the A-drive gear
(#8) until the unit stops because of full gear mesh. Now back off the
indicator totalizer mechanism 1/64 inch and tighten mounting screws
(#6).
‡6. BONNET ASSEMBLY (#1)
should be cleaned and replaced over
the indicator-totalizer unit (#5) after replacing the desiccant bag.
Secure four screws (#2) beneath the bonnet lid. Do not over tighten
the mounting screws (#2) as this will result in damage to the screw
o-rings (#3).
XI. TROUBLESHOOTING
the transmitter is necessary if it is apparent that
the instrument being controlled by the transmitter is not receiving a
proper signal from the transmitter, and/or the totalizer or indicator-
totalizer is not functioning. Before beginning, it is important to be
sure that the problem is with the transmitter, therefore, the following
checks should be made.
1)
Check to be sure that water is flowing
through the meter at flows above the minimum flow rate for the
given size meter.
2)
Check the instrument to be sure it has the
required power being supplied to it.
3)
Check the junction box to be
sure the communication lines from the transmitter to the instrument
are making good contact and that the transmitter is wired properly
to the instrument.
1. THE TROUBLESHOOTING GUIDE
is provided to help isolate any
problem that may occur with the transmitter. Follow the instructions
and test procedures listed for each problem.
A.
If the meter totalizer or indicator-totalizer
does not
work, but
the remote instrument
does
operate (receiving the proper signal),
then see section VI, VII-1 thru 4, IX and X-1 thru 3 for checking the
totalizer, or section VI, VIII-1 thru 5, IX and X-4 thru 6 for checking the
indicator-totalizer.
