Signal assignment
In this step the configured signals can be assigned to the previously selected re-
lay. Using the push-rotate button allows to select the available signal categories
one by one: Threshold, cyclic switching function and sensor error. Additionally,
the working principle and the reset option can be defined.
The following picture displays the assignment menu for threshold settings. The
numbers represent the signals one to nine configured before. By rotating the
push-rotate button each of the numbers can be selected. To assign a signal the
button needs to be pressed. The selection is shown by a black background be-
hind the chosen number.
Relay 1 – threshold signal:
In the picture signal 1 is currently assigned to relay 1. The curser on signal 2 sig-
nals the user the position on the display. For the signal on which the cursor is
currently positioned, the configuration is shown in the bottom line of the screen.
In the picture for signal 2 the threshold configuration is CH2 > 175.0 °C
Relay working principle
For each of the relays the working principle can be adjusted to open circuit prin-
ciple (NO) or closed-circuit principle (NC). The default setting is closed-circuit-
principle (NC) for profile 1. Closed-circuit principle means that in case of no
event the relay coil is energized immediately. If an error occurs the relay de-ener-
gizes.
