Additional Setup If Required; Iii.1 Totalizer - Toshiba LF622 Quick Start Manual

(Note 3. The excitation current of the detector is normally stamped on the small metal plate on
the neck of the detector body that indicates the direction of flow. It can also be found on the
calibration sheet that comes with every meter. For the LF series flow meter, size 20" and above,
the excitation current remains at 0.2000 A, and the K-factor for the detector is used instead.)
(Note 4. The excitation frequency is 24Hz for meters 8" and below; 12Hz for meters up to 16";
and 6Hz for 18" and up. The excitation frequency automatically changes with meter size,
therefore there is no need to set, but one can always verify)
(Note 5. Range Type is default at SINGLE, but can be change, if other flow options are required.
Also when there is a meter size change from the default (or otherwise), the range value will be
change to m/s. When changing to gal/min, it is necessary to change units first, then set correct
range value)
III. Additional Setup if required
III.I Totalizer
- Count rate for totalizer is set in menu J: CNT/PLS; select CNT RATE, and set the
desired value (note 6)
- Using digital outputs for pulse out of the total is done in menu H:DO; Either DO1 FUNC
or DO2 FUNC can be set to PLS OUT, PLS FRD or PLS REV (note 6)
Unit for total display, is set in menu B:DISPLAY; select DSPL2 (default unit = COUNT
-
B), and set the desired unit (note 6)
