Time switch (DTC)

The "time switch" (DTC) function, along with the real-time clock in the converter, offers the

option of controlling when signals are switched on and off.

● Switching temperature control from day to night mode.

● Switching a process control from weekday to weekend.

The converter has three independently adjustable time switches. The time switch output can be

interconnected with every binector input of your converter, e.g. with a digital output or a

technology controller's enable signal.

● Enable parameterization of the DTC: p8409 = 0.

As long as the parameterization of the DTC is enabled, the converter holds the output of all

three DTC (r84x3, x = 1, 2, 3; r84x3.0 normal, r84x3.1 inverted status message) at LOW.

● Activate/deactivate the weekday

- p8410[0] = 0

- p8410[1] = 1

- p8410[2] = 1

- p8410[3] = 0

- p8410[4] = 1

- p8410[5] = 1

- p8410[6] = 0

● Setting switching times:

– ON: p8411[0] = 20 (hh), p8411[1] = 0 (MM)

– OFF: p8412[0] = 10 (hh), p4812[1] = 0 (MM)

● Enable the setting: p8409 = 1.

The converter re-enables the DTC output.
