4.3 Control key (CTRL)
The CTRL key is located next to the 7-segment-display on the right and
serves as simple operating element on the module. With this key the CP
50x/x can be switched into different operating modes and/or different com-
mands can be issued.
● Distriction is made between short (< 0.5 s), long (> 0.5 s, <10 s) and
very long key operations (>10 s).
● Short keystrokes allow the user to switch and selected between the indi-
vidual commands, while these commands are displayed by flashing in
the 7-segment display. Once the initial status has been reached again
this will be indicated normally again.
● Long keystrokes are used to execute a command and to change into the
new status.
● If the CTRL key is held pressed longer than 10 seconds, a hardware re-
set of the module is triggered.
