positive-going edge of the pulse.
The DPClO-CC has low speed inputs and can accept pulses

neously, in which case the displayed total does not change.
Count Inputs
The
-9,999,999 to
totalizet ’srange is
-9,999,999.
If both inputs are
used, the totalizer displays the difference count between the
two inputs-counts at Input B are added, counts at Input A are
subtracted. In this mode of operation, the

counter with a range of zero to
start from a user-programmed offset value. The offset
value is a positive number and may be up to six digits.
If only one of the count inputs is used, the totalizer becomes
an up counter with a range of zero to

OPERATION
Add/Subtract Counting
There are two count input terminals on the rear of the
totalizer. Count pulses entering Input A (terminal 3) cause
the total to decrement (count down). Count pulses entering
Input B (terminal 2) cause the total to increment (count up).
The totalizer may start counting from zero, when reset, or

value other than zero. The offset may be up to six digits. The
offset cannot be a negative number.

Calculating the Count Scale Factor
The count scale factor is used to convert the incoming count
pulses to the desired unit of measure to be displayed (feet,
gallons, etc.) or to correct for a known amount of error (wheel
wear, viscosity, etc.). This scaler has
six digits available with
a fixed decimal point.

WIRING RECOMMENDATIONS
Following these suggestions will increase noise immunity
and lengthen unit life.
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 the totalizer near a solenoid or
other inductive devices. Supply enough ventilation to keep
the totalizer operating within the temperature specifications.
Do not mount this unit in a heavy vibration area.
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 heat batteries above
