Step 2: Signal Definition - ABB CM-TCN Manual

Currently channel 1 is selected and the configured sensor is PT100. By pushing
the symbol for channel 1 the sub menu is entered. Pushing again will enable the
user to change the sensor type by rotation. To confirm the selection another
push action is needed, the sub-menu is left automatically after confirmation.
The following parameters can be set:

Step 2: Signal definition

In this menu up to nine different signals and three cyclic switching functions can
be configured. A signal setting consists of the threshold configuration, the hys-
teresis and ON- and OFF-delay settings related to the threshold.
With a cyclic switching function regular switching of equipment according to a
defined time schedule can be realized e.g. weekly switching of a fan for 15
minutes to reduce risk of clogging due to non-movement. Next to these two sig-
nals there are further options like fault supervision signals. More information
can be found in chapter relay assignment.
For configuration select signal S1-S9 or cyclic switching function CF1-CF3 by ro-
tating through the menu and push the selected one.
