AutomationDirect CTT Series User manual

3505 HUTCHINSON ROAD
CUMMING, GA 30040-5860
Digital Counter/Timer/Tachometer
CTT Series
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.

Using the counter feature of the CTT to count the total number of pieces in a box to signal a conveyor to advance to the
next station.
Counting Input

Reset
Count
Input Mode
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.
Output Mode
Mode F (F)
When the count present value PV counts up to the count setting value SV both outputs 1 and 2 will turn ON.
The count PV will continue to increment with each input signal. The leading edge of “a reset” input signal at RST1 will
turn OFF both outputs, reset the count PV to 0, and prohibit an input signal from incrementing the count PV. The trailing
edge of the “reset” signal at RST1 enables counting to begin.

To enter the page for parameter setting of the counter, press Äfor the main menu for more than 3 seconds. After the setup
is completed, press Äfor more than 3 seconds under any of the parameter page you are in and return to the main menu.
Timer Example:
A basic Timer used to control a clamp time of a compression model press.When the operator signals the
mold is loaded with material by pressing the start button the hydraulic cylinder closes the press to make a
limit switch which starts the CTT timing. Upon completion of the timer cycle Output 1 is turned on and the
press is opened by the hydraulic cylinder.
Signal On Delay 1 (Sond1)
With power applied to the CTT, the leading edge of an input signal at START will begin the
timing period setting value SV (timing up or down based on parameter (t modE). At
the end of the timing period both outputs will turn ON momentarily for the time set in the output pulse
width parameter (tout1) or will be maintained ON if the output pulse width parameter (tout1) is set
to 0.00. The trailing edge of the “start” signal has no effect on the outputs or timing period. The leading
edge of an “reset” input signal at RST1 will turn OFF the outputs and reset the timing period.
The “reset” signal minimum pulse width is set by reset pulse width parameter
( rtSr ) or DIP Switch 8. The leading edge of an “pause” signal at GATE will pause the
timing period after it has been started. The timing period will continue after the trailing edge of the
external switch “pause” (Gate) signal. When power is removed, both outputs will turn OFF and the
timing period will be reset.

Keypad set up of the parameters in the Timer:
Tachometer Example:
Using PSCALE to convert pulses into engineering units
The PSCALE feature of the CTT is very useful in converting the pulsed signal from an encoder or sensor into some
usable unit of measurement.
For example if one was to connect a proximity switch to the CTT to monitor the speed of a motor using a sensing gear
there is a simple calculation to convert the pulses from the sensor to Motor RPMs.
Using this formula you can calculate a PSCALE value to change a pulse signal into RPMs. First obtain the pulses per
revolution (ppr) or number of teeth on the sensing gear for example in the illustration below there are 38 teeth on the
gear or 38 ppr. If the gear is coupled directly to the motor this is all that is required to perform the calculation.
PSCALE = 60/ppr or 60/38
PSCALE = 1.579
With the PSCALE set to 1.579 for every 38 input cycles the CTT will display a value of 1.
Select functions: There are 4 modes in CTT, (left to right) timer, counter, tachometer and timer + counter.

Set up pre-scale value: 1.000 (default 1:1) Range: 0.001 to 99.999
St–taC
Set up the delay time after switching on the power: 0.0 (default). The tachometer will start to run when the set delay
time is due after the power is switched on. Setup range: 0.1 to 99.9 seconds
––00
St–Av6
Set up average value of the input filter: The average value is for making the present value detected by the tachometer
more stable.
The setup range is 0 to 3 (1 = 2 data, 2 = 4 data, 3 = 8 data). For example, if you select “3”, the system will
average the 8 present values from the tachometer to make the present value displayed on the screen more stable.
–rtsr
Set up minimum width of reset signal: Default = 20ms; 1ms is also selectable.
––20 –––1
Select output modes: There are 4 output modes, 2Lo1Lo, 2Lo1Hi, 2Hi1Lo, and 2Hi1Hi, For example, when you select
2Hi1Lo, and assume the first set value is 100 (2Hi) and the second 50 (1Lo), the output value of the tachometer will be
below 100 (2Hi) and above 50 (1Lo) and CTT will not perform an output. If the set value exceeds the range, CTT will
perform an output.
