Generator Installation/Removal
Generators are inserted into the optional generator
housing attached to the bottom of the sensor housing at
the base of the transmitter. Before installing the
generator, check to see that the set screw on the side of
the holder is loose and does not contact the generator
during installation. An indexing groove on the side of the
generator aligns the connector for a perfect fit. Once
installed apply a little pressure to the top of the generator,
and tighten the set screw (using the ATI screwdriver) on
the housing to provide a secure fit. If the set screw is not
secure, the connector on the generator may disengage
causing a “generator missing” error message on the
display.
To remove the generator from the holder, loosen the set
screw on the side of the holder and pull up on the outlet
stem.
An O-Ring in the sensor cap provides the mechanism for
securing the generator to the transmitter. Simply press
the generator into the bottom of the sensor cap until it is
secure.
