Digital Counter / Timer / Tach User Manual, 1st Ed.

General Description

The CTT series is an extremely versatile multi-function device that is easily configured for operation as a digital
counter, timer, combination timer + counter, or tachometer. Both voltage and non-voltage inputs are accepted
from a wide variety of sensor types with NPN, PNP, or dry contact outputs. The first output on the CTT is
a single-pole, single-throw relay and NPN transistor that operate concurrently. The second CTT output can
be ordered as either a single-pole, double throw relay or NPN transistor. Parameters are easily set using the
externally accessible DIP switches or the lockable keypad. The double-line, 6-digit, two-color LCD display
shows the counter, timer, or tachometer present values, setting values and menu parameters during set-up.
Additional individual indicators are provided for inputs, outputs and functions. The standard 1/16 DIN size,
included panel mounting clip and gasket make panel mounting a snap. The CTT is available in 120-240VAC
and 24VDC powered models.

Getting Started with Counters

Step 1: Determine Required Counter Function

Counter Functions

1-Stage Counting (

StA6E 1

)

A single count setting value SV is available in 1-Stage Counting. Both Outputs 1 and 2 operate concurrently and will
turn ON momentarily or will be maintained ON depending on the Output Mode selected.

2-Stage Counting (

StA6E 2

)

In 2-Stage Counting, count setting value SV1 controls Output 1 and count setting value SV2 controls Output 2.
Outputs will turn ON momentarily or will be maintained ON depending on the output mode selected.

Batch Counting (

bAtCH

)

In Batch Counting, count setting value SV controls Output 2 which will turn ON momentarily or will be main­tained ON depending on the output mode selected. Count setting value BATCH SV controls Output 1which will
be maintained ON.

Total Counting (

totAL

)

A single count setting value SV is available in Total Counting. Both Outputs 1 and 2 operate concurrently and will
turn ON momentarily or will be maintained ON depending on the Output Mode selected.

Dual Counting (

dUAL

)

A single count setting value SV is available in Dual Counting. Both Outputs 1 and 2 operate concurrently and will
turn ON momentarily or will be maintained ON depending on the Output Mode selected.

Step 2: Determine Required Counter Input Mode

Counter Input Modes:

Counting Up (UP)*

With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will increment the count
present value PV by 1. Turning ON the input signal at CP2, will prohibit the input signal at CP1 from incrementing
the PV.

With the input signal ON at input CP1, each trailing edge of the input signal at CP2 will increment the count
present value PV by 1. Turning OFF the input signal at CP1, will prohibit the input signal at CP2 from incre­menting the PV.

Counting Down (

down

)*

With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will decrement the count
present value PV by 1. Turning ON the input signal at CP2, will prohibit the input signal at CP1 from decrementing
the PV.

With the input signal ON at input CP1, each trailing edge of the input signal at CP2 will decrement the count
present value PV by 1. Turning OFF the input signal at CP1, will prohibit the input signal at CP2 from decre­menting the PV.

Counting Up / Command Counting Down (

Ud A

)*

With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will increment the count
present value PV by 1.

With the input signal ON at input CP2, each leading edge of the input signal at CP1 will decrement the count
present value PV by 1.

Counting Up / Counting Down (

Ud b

)*

Each leading edge of the input signal at CP1 will increment the count present value PV by 1.

Each leading edge of the input signal at CP2 will decrement the count present value PV by 1.

Digital Counter / Timer / Tach User Manual, 1st Ed.

1-800-633-0405

2-4

Quadrature (

Ud C

)*

When the quadrature input signal at CP1 changes before the input signal at CP2, the trailing edge of CP2 will incre­ment the count present value PV by 1.

When the quadrature input signal at CP2 changes before the input signal at CP1, the leading edge of CP2 will decre­ment the count present value PV by 1.

Addition (

Add

)**

Each leading edge of the input signal at CP1 will increment the count present value PV by 1.

Each leading edge of the input signal at CP2 will increment the count present value PV by 1.

Subtraction (

SUb

)**

Each leading edge of the input signal at CP1 will increment the count present value PV by 1.

Each leading edge of the input signal at CP2 will decrement the count present value PV by 1.

width parameter (

rtSr

) or DIP Switch 8.

Mode Q (q)

When the count present value PV counts down to 0 both outputs 1
and 2 will turn ON momentarily for the time set in the output pulse
width parameter (

tout2

). The count PV will continue to decre­ment with each input signal until the end of the output pulse time
when the outputs turn OFF and the count PV is reset automatically
to the count setting value SV.

The leading edge of a “reset” input signal at RST1 will turn OFF
both outputs, reset the count PV to the count SV and prohibit an
input signal from decrementing the count PV. The trailing edge of
the “reset” signal at RST1 enables counting to begin.

The “reset” signal minimum pulse width is set by reset pulse width
parameter ( rtSr ) or DIP Switch 8.

Mode A (A)

When the count present value PV counts down to 0 both outputs
1 and 2 will turn ON momentarily for the time set in the output
pulse width parameter (

tout2

). The count PV will remain at 0

regardless of additional input signals.

The leading edge of a “reset” input signal at RST1 will turn OFF

1-Stage Counting (

StA6E 1

)

A single count setting value SV is available in 1-Stage Counting. Both Outputs 1 and 2 operate concurrently and
will turn ON momentarily for the time set in the output pulse width parameter (

tout2

) or will be maintained ON

depending on the Output Mode selected.
