SETTING UP THE INDEX ASSEMBLY
Output Shaft Rotation
To change the rotation of the output shaft to counterclockwise (figure
1.Loosen set screw e on gear E.
2.Disengage gear E from counter gear D.
3.Tighten set screw e.
4.Loosen set screw c on gear C.
5.Engage gear C with counter gear D.
6.Tighten set crew c.
7.Take care to align the gears properly, and verify that they turn freely and do not bind.
Figure 2- 2 Index Box Assembly
Input Drive Value
Fig. 2-2 above shows gearing in the correct position for 10, 100, 1,000 or 10,000 cubic
feet/revolution (ft3/rev) and 0.1, 1 and 10 cubic meters/revolution (m3/rev). To change the input drive value to 5 ft3/rev:
1.Loosen set screw a on compound gear A.
2.Lower gear A until its upper teeth engage the upper teeth of compound gear B.
3.Tighten set screw a.
4.Take care to align the gears properly, and verify that they turn freely and do not bind.
When changing a MTEK6000 in the field from a 10, 100, 1,000 or 10,000 ft3/rev drive meter with a 5 ft3/rev drive, the CF per Pulse In or Meter Drive parameter, must be changed to a value of 10 using software or the optional, external keypad / display.
NOTE
Electronic parameter CF per Pulse In or Meter Drive should always equal the meter drive value EXCEPT for 5 ft3/rev meters which should be set at 10. When switching to
5ft3/rev, the gear ratio is adjusted so that two revolutions of the input drive gear result in one revolution of the magnet and hub assembly, which sends a pulse signal to the instrument that equals 10 ft3/rev. The value can be changed using software or the optional, external keypad / display (see Appendix A for addressing).
To change the input drive value to 10, 100, 1,000 or 10,000 ft3/rev, return compound gear A to its original,
