Sponsler, Inc. IT150N Remote Totalizer pg 4 DOC# MN-150N-B INTRODUCTION General The Model IT150N Industrial Remote Totalizer is a battery powered device that provides flow totalization in any engineering unit. Total is displayed via an 8 digit liquid crystal display. Reset of the totalizer is accomplished externally by a magnetic field. This particular feature retains the unit’s integrity permitting complete operational control in hazardous environments.
Sponsler, Inc. IT150N Remote Totalizer pg 5 DOC# MN-150N-B INSTALLATION Inspection All units are completely assembled, tested & inspected at the factory prior to shipment. Upon receipt of the unit a visual inspection should be conducted to detect any impropriety or damage that may have occurred during shipment. Report any discrepancy to the factory immediately.

The amplitude of the signal generated by the turbine is proportional to the rate of flow; therefore, sensitivity should be adjusted at the lowest usable flow rate. Rotate R1 completely counterclockwise then slowly rotate R1 clockwise until the display correctly responds then increase R1 slightly clockwise.

Reset is initiated externally by placing a magnet in the proximity of reset S7 located on the Display P.C.B. and indicated on the enclosure label as ‘RESET’. FIGURE 4 MISCELLANEOUS Factored Digital Pulse Output This signal is an open drain configuration which can sink 1A continuously. The maximum drain voltage should not exceed 150VDC (V+).

CAUTION: Do not use the LCD model or S7 as grip points to remove the board stack. Use the extended screw mounts provided. To put the 3 board stack back in the condulet, align as illustrated and push down.
