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.

APPLICATION

You must make certain programming and

wiring choices to accomplish your application. We recommend the following sequence:

Answer the following questions:

What type of

What engineering units should the counter be scaled

sensor will be used?

to?

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.

Screens There are four program-mode screens

in the

DPCl 0-CS

and

DPClO-CC. Upon entering the setup mode, thecounterwill

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

may

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 counter with a range of zero to

-9,999,999.

99,999,999,

or a down

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

Count Inputs

DPClO-CS

The from solid state, current sourcing sensors at up to 10 input. The sensor must supply at least more than

has hi-speed inputs and can accept pulses

+2.0

V dc, but not

+28

V dc to the input. Counts are entered on the

kHz

per

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

from solid state, current sinking sensors or contact closures to ground at up to 20 Hz per input. These inputs are internally

pulled up to

V dc. The sensor must be capable of sinking current from the input to bring the input voltage down to +0.4

V dc or less. Counts are entered on the negative-going

edge of the pulse.
