CTT Counter Timer Tachometer – Timer Modes

The CTT series from Automation Direct are multi-function digital units. They incorporate a multi-function digital counter, timer and tachometer all within the same unit. The timer mode will operate in twelve (12) different ways.

We will be looking at each of the timer modes on this versatile digital unit. Let’s get started.

Previously in this CTT Series – Counter / Timer / Tachometer we have discussed;

All timer applications begin with a timing chart. The secret of using timers is a good place to start for a review of how timing charts work.
Programming these units can look like a hard task. The manual is over 260 pages! However there is an easy way. The manual is broken up into chapters for each of the operation modes of the CTT. (Counter, Timer, Timer + Counter, Tachometer)
Once we find our operation mode, you look for the timing chart mode for your application. The manual includes all of the information that you need for that mode. This includes wiring diagrams, timing charts, program steps and dip switch settings.
ExampleSignal On Delay 1 timer mode – Page 3-4 and 3-5 contain all of the information needed to program this mode.
