INTRODUCTION

PROGRAM MODE

Your OMEGA

DPCl 0-CS or

DPCIO-CC

is a counter with an eight-digit LCD display. A programmable scaler and decimal point allow for display in any engineering unit.

How many pulses per item is the sensor providing?

Is a decimal point needed on the display?

Calculate the scale factor.

MOUNTING

NOTE: To enter the program mode, you must connect a jumper between terminals 1 and 5 (see page 4). To leave the program mode, disconnect the jumper.

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 is a positive number and may be up to six digits. If only one of the count inputs is used, the totalizer becomes

edge of the pulse.

COUNT SCALER 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.). 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.

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

Do not recharge lithium batteries

Do not dispose of batteries in fire

Insert battery with correct polarity
