APPLICATIONS
This totalizer is intended for simple totalizing applications.
One count input pulse per item is necessary. The only
decisions to be made are:

OPERATION
The totalizer display has lead-zero blanking. No decimal
point is available.

Do you use the high or low speed input?
Do you want the front panel reset button active?
Terminal 3 is pulled down to common. When
supplies voltage to this terminal, one count is registered on
the display. The sourcing signal must supply at least

Terminal 2 is the low-speed, current-sinking count input
designed to be used with a contact closure to ground. It has
a maximum count speed of 20 Hz. Inputs into this terminal
are counted on the negative-going edge.

WIRING RECOMMENDATIONS WIRING DIAGRAMS
Following these suggestions will increase noise immunity
and extend the life of the product.
Cable:
Make the connection between the count source and
the totalizer with a two-conductor shielded cable. Connect
the shield to earth ground at one end only.
Relay Coil Suppression:
count source, suppress the relay coil. This can be accom-
plished with an RC network for AC coils or a diode for DC
coils.
Mounting:
inductive devices. Supply enough ventilation to keep the
totalizer operating within the temperature specifications.
BATTERYSAFETY
The lithium battery that powers your device contains inflam-
mable materials such as lithium organic solvent, and other
chemical ingredients. Explosion or fire may result if the
battery is not handled correctly.
