9.1 Disassembly of DON with Pulse meter
Concerning options Hx, Dx, Gx, Bx, Kx and Rx
9.1.1 Pulse output board removal (refer exploded view diagram)
To remove the pulse output board, remove the 4 electronic cover screws (10),
and remove the electronic cover (9). The pulse output board (6) can now be
accessed and removed via the removal of the electronic board screws (7).
9.1.2 Oval gear removal for DON-x05…DON-x15 (refer exploded view
diagram)
For access to the oval wheel, remove the 4 lower meter body screws (5). With
care, remove the upper meter body assembly (4) being careful not to damage or
misplace the O-ring (3) or changing the positioning of the oval wheels (2) and/or
damaging them.
For DON models DON-x05 to DON-x10, when disassembling, please notice the
dimples located on the meter bodies (1 & 4) face just outside the o-ring groove.
These dimples must align with each other, when the meter is re-assembled. In
addition, for these smaller flow-meters, only one oval wheel is equipped with a
magnet. The oval wheel without magnet must be mounted on the bearing pin
closest to the dimple marking. For these oval wheels, the sides without boring
hole for the magnet must face upwards, see detail A. With all other units, both
oval wheels are equipped with magnets.
