APPLICATIONS
This totalizer is intended for simple totalizing applications.
One count input pulse per item is necessary. The only
decisions to be made are:
1. Do you use the high or low speed input?
2. Do you want the front panel reset button active?

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. To avoid an accident follow
these guidelines:
?? Do not stack or jumble up batteries
?? Do not heat batteries above 95°C
?? Do not disassemble batteries
?? Do not recharge lithium batteries
?? Do not apply pressure to, or deform batteries
?? Do not solder to batteries
?? Do not dispose of batteries in fire
?? Insert battery with correct polarity

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: If a relay contact is used as a
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: Do not mount he totalizer nearasolenoidorother
inductive devices. Supply enough ventilation to keep the
totalizer operating within the temperature specifications.
