2.4 Timer + Counter (Mixed Mode)
CTA offers timer + counter mode. The timer corresponds to OUT1 (output 1) and the counter to OUT2 (output2).
In this mode, the timer and counter both have a phase signal input; therefore, part of the functions will be
limited. For example, there are 12 output modes for the timer of CTA, but only 8 output modes available in the
timer + counter mode (Rcy2, Scon, Ston and Stoff are not available). In addition, the mixed mode only offers
input modes Up and Down for the counter and S, T, D are no longer available in the output modes. See 2.4.1. for
how to set up the parameters in the mixed mode.

To enter the page for parameter setting of the timer + counter, press
in the main menu for more than 3
seconds. After the setup is completed, press
for more than 3 seconds under any of the parameter page you
are in and return to the main menu.
